---------------------------------------------------------------------- Date: Wed, 30 Nov 1994 14:42:33 -0600 From: keithfrank at dow.com (Keith Frank) Subject: Celis Raspberry trade / Sam Adams(tm) clone / Non-alcohol beer *** From Bruce DeBolt *** I will travelling to Richmond, VA on Dec. 6, arriving late afternoon/ evening. If anyone in the area is interested in Celis Raspberry beer I would be willing to bring a six pack in exchange for a regional micro six pack, especially if it is a holiday/winter type. Private e-mail on this please. My understanding is that Celis Raspberry will not be distributed nationally until this spring. Regarding the Sam Adams clone request from Jack Skeels (I hate to post this, especially after blasting Boston Beer Works in previous posts, but to help an interested homebrewer...). I made one last January using a blend of pale and amber extracts (about 1.050 o.g.), Wyeast 1056 fermented at 55-60F, and dry hopping with 1 oz. of Liberty pellets in the secondary. I was shooting for a lager type mellowness by fermenting at low temperature and it worked well. It was probably the most popular beer I've made for the non-homebrewing friends. Don't have the details at the office so apologize for lack of quantities, etc. There was a post about the usefulness of the Carbonator cap yesterday, I'd like to add one more. At the request of a pregnant friend I made low-to-no alcohol beer by heating a Sierra Nevada type pale ale homebrew to 180F (azeotrope for ethanol/water is 172F) for 5-10 min. with stirring, then cooling rapidly and force carbonating in a 16 oz. PET bottle using the Carbonator cap. I used about 25 lb pressure and placed in an ice water bath for 1-2 hours with lot of shaking. It worked very well. I had no way to quantitate the alcohol content but judging from the volume loss and the (lack of) taste I think it was nil. Taste was much better than O'Doull's, etc. but of course not up to the real thing. Bottom line is she liked it. I am going to try this with some other styles and will report later if there is interest. By the way, the beer freezes much quicker without the alcohol, we found out the hard way on the first attempt to carbonate it quicker. No affiliation with the product, etc. Bruce DeBolt Lake Jackson, TX c/o keithfrank at dow.com Return to table of contents
Date: Wed, 30 Nov 1994 16:07:02 -0500 (EST) From: eric addkison pendergrass <pendeea3 at wfu.edu> Subject: Blueberry Stout / Raspberries / Newcastle Recipe A friend and I are brewing a an Irish stout and want to flavor it with some sort of fruit (like blueberries). I was wondering how much to use, and what, if any, special techniques to employ. As well, if there are any other fruits (besides blueberries or raspberries) which would work well I would appreciate the input. - -------------- I put about 30 oz. of canned raspberries in the secondary of a german alt, and was wondering if I should have crushed the raspberries first (to make full use of the juices trapped in the berries). Is this generally what is done, or are these types of fruits generally left whole? - -------------- Kevin Fons asked about a recipe for Newcastle Brown Ale. Here is one which is supposed to be similar: From: carl.price at cae.ppd.ti.com (cprice) Newsgroups: rec.crafts.brewing Subject: Re: New Castle Brown Ale Recipe ? Date: 12 Oct 1994 20:09:03 GMT I made Papazian "Naked Sunday Brown Ale" several months ago and was very impressed with the similarity to New Castle. HomeBrew Headquarters didn't have the canned/hopped extract that Papazian's recipe called for so I used: 2lbs of Pale Malt extract 4lbs of Amber Malt extract 1oz Willamete Hops (boil) 1/4 tsp Irish Moss (last 15 min) Boil the whole mess 1 hour. Pitch yeast. I used the Wyeast British Ale "smack pack" started the day before.

Date: Wed, 30 Nov 1994 16:30:15 -0500 (EST) From: "nancy e. renner" <nerenner at umich.edu> Subject: Watery beer, airlock siphon, Wiley mill (From *Jeff* Renner) Eamonn McKernan has watery beer (as I recall, a lager at ~1044) that he wants to "doctor." First, Eamonn, let me suggest that, since you say thihs has happened twice, perhaps your hydrometer is off. A 1044 beer really shouldn't taste watery. I've seen hydrometers off by .008. Maybe your extraction isn't as efficient as you think. Tap water at the specified temp. (prob. 15^C) is pretty close to 1.000, but use distilled water. I went through about a dozen in the bin at my shop before getting one that was accurate. Next, what about that beer in your secondary. I really wouldn't think it would work too well to add a large amount of fermentables to it. Here are some ideas - hop tea (if it is underhopped), crystal malt "tea" for priming, roast malt "tea" (probably chocolate) for color and flavor interest. Or brew up a bull batch of overkill lager and combine the two. *** I may have been misunderstood when I mentioned siphoning of chlorine water into my beer. I meant from the blowoff bucket thru the blowoff tube. That's why I use a one piece airlock first. I like to use vodka, too, even though water may work. Vodka is especially important when lagering, when water might freeze. *** v.f. daveikis has a Wiley Mill. I think the Coyote should know about this! It is probably mfg. by Acme. ;-) What I think you have, v.f., is a hammer mill. Our local organic flour mill uses one, which they like because it doesn't raise the flour temp as much as stone mills. Usually I've seen them at feed stores, where they are used for grinding grains for livestock. I think it'd be hard to control the crush - it'd probably be too fine and the husks would almost surely be too fine for lautering efficiency. But try it in situ bevore you move it!

Date: Wed, 30 Nov 1994 16:56 EST From: CSS2 at OAS.PSU.EDU (SPEAKER.CURTIS) Subject: which soda keg is better? A question for the collective wisdom of the HBD: I am considering getting a spare fridge and a soda keg setup for my homebrew...I'm tired of filling and capping bottles, and at $33 a case I can't buy enough Grolsh to give me sufficient swing-topp bottles...SO I have access to both Pepsi and Coke kegs, I mean pin-lock and ball-lock kegs from various connections that I have, so the question is - which is better? Is one version better than the other? Any inherent problems with either type (ie., harder to sanitize, leaks more often, etc). Before I go ahead and start buttering up people for kegs, I'd like to know which is better for beer applications - or is there no difference??? Private email is fine; if anyone is interested, I'll post the results later. Thanks and Hoppy Brewing Curt css2 at oas.psu.edu Return to table of contents

Bob Paolino <uswlsrap at ibmmail.com> urged supporting local brewers. I heartily second Bob's message. Support your good local brewers! Support your good local brewers! (At least when you run out of hb.) Fortunately, GVSU is located near Kalamazoo, home of Bell's. If Bell's several ales don't provide enough variety, Frankenmuth's pilsner is pretty good even if it's from the east side of the state (but leave alone their "old detroit" ale or whatever it's called).

Date: 30 Nov 1994 13:22:48 U From: "Manning Martin MP" <manning_martin_mp at mcst.ae.ge.com> Subject: Fermentor Geometry This is an interesting subject indeed. Why not stir up a fermentor geometry debate? I still think that the difference in geometry between a carboy configured (filled) for blow-off vs. not is insignificant, but as regards my other comments on fermentor geometry, Jeff Berton provided me with the info Al K. referenced. Looks like I missed this one the first time around. I do not claim to be an expert on this subject, but I still don't see what it is about the geometry that could possibly be causing the effects descrbed. Perhaps even more curious is the extreme sensitivity or lack thereof in different strains. G. Fix> I feel this depends very much on the yeast strain used. For example, GF> W-34/70 makes much better beer when fermented in a squat 1/4 bbl. GF> pony keg than it does in a Cornelius keg. The effects are striking GF> and include fermentation times (7-8 days vs. 18-21 days), longer GF> lag times (4-6 hrs vs. 24-36 hrs.), and higher end point diacetyl GF> levels. On the other hand, strains like St. Louis lager (aka A-B GF> lager) do not seem to be affected as much. These changes are so dramatically different that it seems like some other variable has changed. Perhaps there was variation in the pitching rate or wort aeration? (Lag and ferment times are sensitive to these). Were the wort compositions similar? How many tests were done? GF> The data on W-34/70 refers to fermentations at this strain's GF> optimal temperature; i.e., 48F. If this was the ambient temperature, rather than the internal (beer) temperature, perhaps the geometry difference (surface/volume and thin-walled soda keg vs thick-walled quarter barrel, and likely better convective heat transfer coefficents on both the beer and air sides for the taller vessel) changed the heat transfer from the fermenting beer enough to change its internal temperature significantly? The soda keg will certainly ferment cooler than the quarter for the same ambient temperature, and, it is well known that different strains quit at different temperatures, and that a few degrees can be significant for any given strain. GF> I cited only lager yeast, but the same issues apply to GF> ale strains as well. A striking case is the new single strain GF> Whitbread yeast. It has been trashed because of poor attenuation and GF> flocculation in tall unis. This is curious; poor attenuation and poor flocculation do not often go together. Also, these are tall commercial tanks right? "Tall" means how many feet? On system size.. >George Fix> In fact, it is just the opposite, and indeed these effects seem >GF> to be the most significant for small systems. DeClerck did most >GF> of his work on his liter sized lab system (see e.g. the references >GF> quoted in Textbook of Brewing, Vol. 1) I'd like to check this out, but I don't own a copy of the book.

I have had the pleasure of drinking my 1st partial mash over the last few days! it is great! Big hit at a party we had the other night. I would like to thank all of you netbrewers who assisted me in getting expected values for various grains and advice on partial mashes etc. The brew is very smooth with a nice head (first brew I have done in 9 batches that I can say that) enough hops to make them noticable but overpowering (I'm no hop head) and a nice residual sweetness. This may become the first House Brew! Recipe available upon request! By the way Dale with the barley llergy. I tried to mail you and it bounced.

Date: Wed, 30 Nov 1994 15:56:23 -0800 (PST) From: Jeremy Ballard Bergsman <jeremybb at leland.Stanford.EDU> Subject: FOOP, brown malt, watery lager, O2 I have been holding back from the FOOP discussion but in the last HBD there were several statements I felt I had to comment on. _____________ From: Domenick Venezia <venezia at zgi.com> Most denatured proteins will spontaneously "renature" when returned to the original conditions. Presumably if a protein is "natured" when in solution in the beer/wort, then denatures by the hydrophilic/phobic forces in the foam, then falls back into solution it will refold to its original configuration. - ------------- I think you should ask one of the yeast guys where you work to vortex up some kind of enzyme really well, let the foam subside, then try using it. Protein folding is one of the mysteries of biology and most proteins will not correctly re-fold once denatured. He continues: _____________ Actually, given that the foam is a result of denatured (extended) proteins, it doesn't matter how the protein folds in solution and it doesn't matter whether it returns to its "original" configuration, since its behavior in solution does not determine foam production. Given that foam production is the result of the hydrophilic/phobic character of the proteins, and that hydrophilic/phobic character of the protein is solely determined by its sequence of amino acids, unless that sequence changes, e.g., the chain is broken or chemical bonds are broken, its hydrophilic/phobic character can not be "used up" or changed. - ------------- I agree with the first part. Unlike the enzyme in my example above, the exact folding shouldn't matter, but contrary to the latter statements, denaturing proteins may lead to their hydrophobic areas associating with each other, with the hydrophillic areas being exposed to the solution. This could reduce the surface action of the protein. The character is not used up, but hidden. I am also skeptical that this effect is real. I'm also going to agree with Phil Miller by disagreeing with some of his statements. ____________ From: pmiller at mmm.com (Phil Miller) The main chain bond in polystyrene is a C-H bond, same as a protein, right? So I don't think protein molecules are inherently 'weaker' than polystyrene molecules... - ------------ I'm sure Phil meant to say that the main chain bond in polystyrene is a C-C bond. This is not the same as in proteins which are -C-C-N-C-C-N-, with every other C having a double bonded oxygen on it, contributing some double bond character to the main chain. Again I am skeptical of the effect of FOOP, especially as mediated by chain breakage. These bonds are pretty strong. Here is my experiment. I have a bottle of beer on my kitchen counter. I am going to give it a good shaking every time I think to. I will time how long the foam lasts the first time and later if it seems to get shorter. *************************** From: Eamonn McKernan <eamonn at rainbow.physics.utoronto.ca> I have a watery lager in the secondary. I want to add some flavour, but not much (if any) more alcohol. - --------------- First, I find that flat beer from the fermenter always tastes more watery than it will later. Maltodextrin will add residual sweetness (and body?). Dry hopping will add flavor (Sam Adams dry hops their lager). A mini mash of some (.5 lb?) light crystal (boil and cool before adding) might flesh things out a bit too. I wouldn't worry about adding fermentables at this stage, but you will have to age it more. *************************** From: raines at radonc.ucla.edu (Maribeth_Raines) I am looking for a commercial source of brown malt. I know this was discussed about a year ago. and I'm looking for some to brew an original british porter. - --------------- The Beverage People in Santa Rosa, CA carry this. Call 1800-555-1212 for their number. I did this earlier this year and it turned out great except for a better than average mash yield resulting in an OG of 1.077! Adding some Brettanomyces smoothed out the esteriness. She also adds, _______________ There are several things which suggest at least to me, to aerate after pitching. First is that the *maximum* amount of oxygen that can be dissolved in cooled wort is 8 ppm. - ---------------- Note that this is only for adding oxygen with air. The levels can be made much higher with pure O2 gas, which is used by many commercial breweries. Jeremy Bergsman jeremybb at leland.stanford.edu Return to table of contents
Date: 30 Nov 94 19:24:27 EST From: John Grant <74444.3034 at compuserve.com> Subject: Historical Recipes from Canada Hi Folks! Here a few interesting historical brews from Canada. All of these recipes are taken from "Young's Demonstrative Translation Of Scientific Secrets; Or A Collection Of Above 500 Useful Receipts On A Variety Of Subjects" by Daniel Young. Printed by Rowsell & Ellis, King Street East, Toronto, Canada, 1861. The entire document was deciphered, computerized, and uploaded to the Compuserve TWHOME Forum (secret.zip) by Paul Hubbs and Bob Gravonic of Toronto. Cider Without Apples To each gallon of cold water put 1 lb. common sugar, 1/2 ounce of tartaric acid, one tablespoonful of yeast, shake well, make in an evening and it will be fit for use next day. I make in a keg a few gallons at a time, leaving a few quarts to make into next time, not using yeast again until the keg needs rinsing. If it gets a little sour, make a little more into it or put as much water with it as there is cider and put it with the vinegar. If it is desired to bottle this cider by manufacturers of small drinks, you will proceed as follows: put in a barrel 5 gallons of hot water, 30 lbs. of brown sugar, 3/4 lb. of tartaric acid, 25 gallons of cold water, 3 pints of hop or brewer's yeast, work into paste with 3/4 lb. of flower, and one pint water will be required in making this paste; put all together in a barrel which it will fill and let it work 24 hours, the yeast running out at the bung all the time by putting in a little occasionally to keep it full; then bottle, putting in two or three broken raisins to each bottle, and it will nearly equal champagne. Spruce or Aromatic Beer Take 3 gallons of water, 2 1/2 pints molasses, 3 eggs well beaten, 1 gill yeast, put into two quarts of the water boiling hot, put in 50 drops of any oil you wish the flavour of, or mix one ounce each, oil sarsafras, spruce, and wintergreen; then use the 50 drops. For ginger flavour take 2 ounces ginger root bruised and a few hops, and boil for 30 minutes in one gallon of the water, strain and mix all; let it stand 2 hours and bottle, using yeast, of course, as before. Lemon Beer To make 20 gallons, boil 6 ounces of ginger root bruised, 1/4 lb. cream-tartar for 20 or 30 minutes in 2 or 3 gallons of water; this will be strained into 13 lbs. of coffer sugar on which you have put 1 oz. oil of lemon and six good lemons all squeezed up together, having warm water enough to make the whole 20 gallons, just so you can hold your hand in it without burning, or some 70 degrees of heat; put in 1 1/2 pint hops or brewer's yeast worked into paste as for cider, with 5 or 6 oz. of flower; let it work over night, then strain and bottle for use. This will keep a number of days. Philadelphia Beer Take 30 gallons of water, brown sugar 20 lbs., ginger root bruised 1/4 lb., cream tartar 1 1/4 lb., carbonate of soda 3 ounces, oil of lemon 1 teaspoonful, put in a little alcohol, the white of 10 eggs well beaten, hops 2 ounces, yeast one quart. The ginger root and hops should be boiled for 20 or 30 minutes in enough of the water to make all milk warm; then strain into the rest, and the yeast added and allowed to work itself clear as the cider and bottled. A Superior Ginger Beer Take of sugar 10 lbs., lemon juice 9 oz., honey 1/2 lb., bruised ginger root 11 oz., water 9 galls., yeast 3 pints, boil the ginger in the water until the strength is all extracted, which you may tell be tasting the root, then pour it into a tub, throwing the roots away, let it stand until nearly luke warm, then put in all the rest of the ingredients, stir well until all dissolved, cover it over with a cloth, and if it be in the evening, let it remain until next morning, then strain through cloth, and bottle it, and in a short time it will be fit for use. Some use less sugar, and some less lemon juice, to make it with less expense; but it is not so elegant a drink as this. Ginger Pop No. 1 Take of water 5 1/2 galls., ginger root bruised 3/4 lb., tartaric acid 1/2 oz., white sugar 2 1/4 lbs., the whites of 3 eggs well beat, a small teaspoonful of oil of lemon, yeast 1 gill; boil the root for 30 minutes in 1 gallon of the water, strain off, and put the oil in while hot, mix all well, make over night, in the morning skim, and bottle, keeping out sediment. Ginger Pop No. 2 Take best white Jamaica ginger root bruised 2 oz., water 6 quarts, boil 20 minutes and strain, then add cream tartar 1 oz., white sugar 1 lb.; put on the fire, then stir until all the sugar is dissolved; then put into an earthen jar, now put in tartaric acid 1/4 oz., and the rind of 1 lemon, let it stand until 70 degrees of Fahrenheit, or until you can bear your hand in it with comfort, then add two tablespoonsful of yeast, stir well, bottle for use, and tie the corks; make a few days before it is wanted for use. Improved English Strong Beer If you have malt use it, if not, take 1 peck of barley, and put it into a stove oven, and steam the moisture from them, grind coarsely, and pour into them 3 1/2 gallons of water, at 170 or 172 degrees. (If you use malt it does not need quite so much water, as it does not absorb so much as the other. The tub should have a false bottom with many gimblet holes to keep back the grain.) Stir them well and let stand 3 hours and draw off, put on 7 gallons more water at 180 or 182 degrees, stir well, let stand 2 hours and draw off, then put 1 gallon or 2 of cold water, stir well and draw off; you should have about 5 or 6 gallons; mix 6 lbs., coarse brown sugar in equal amount of water, add 4 oz. of good hops, boil for 1 1/2 hour; you should have from 8 to 10 gallons when boiled; when cooled to 80 degrees, put in a teacupful of good yeast and let it work 18 hours covered with a sack. Use sound iron-hooped kegs, or porter bottles, bung or cork tight, and in two weeks it will be good sound beer, nearly equal in strength to London porter, or good ale, and will keep a long time. Hop Beer Take of hops 6 oz., molasses 5 quarts, boil the hops in water till the strength is out, strain them into a 30 gallon barrel, add the molasses and a teacupful of yeast, and fill up with water, shake it well and leave the bung out until fermented, which will be in about 24 hours; bung up, and it will be fit for use in about 3 days. A most excellent summer drink, smaller quantities in proportion. Happy historical experimentation! And, oh yes, Bula! John H. Grant 74444.3034 at compuserve.com Return to table of contents
Date: 30 Nov 94 20:44:01 EST From: Don Rudolph <76076.612 at compuserve.com> Subject: SA Clone, FOOP Geez, the last few HBD issues have been GREAT with lots of interesting threads. I'd like to join in the fray if I may. - ----------------- Jack Skeels says he's ashamed to ask for a SA clone recipe. I'm not. Send them on to me! I like the beer. - ----------------- FOOP debate rages on, great stuff. Domenick, my (cloudy) understanding of protein chemistry is that denaturing can be a permanent condition. For example, if an alpha helix of a protein is denatured, the H-bonds that hold the baby together fall apart. As long as the concentration of proteins is not too high, the alpha helix will spontaneously revert to its original shape when the conditions (pH, temp) permit. But if H-bonds are formed with nearby amino acids from other polypeptides or from other parts of itself, the protein will be a tangled mess. The reason protein structures are so orderly and neat is the way are synthesized, polymer- ized, and packaged by other enzymes .. and I'd venture to say that they are easily messed up. I mean try to get a fried egg to revert to good ol' runny albumin. Can't do it. Anyway, I vote for the possibility of permanent denaturation of heading proteins in beer.

I happen to have my log book at work so I could send a recipe to brother Kyle Roberson, and it happens to have a Kolsch recipe that turned out OK. Want it? OK here it is: 7.5 lb Belgian Pils Malt 1 lb Wheat Malt .25 lb 40L Crystal 1.5 oz Tettnanger (aa = 5.5%) 60 min .25 oz Tettnanger 20 min .25 oz Saaz (aa = 2.8%) 20 min .25 oz Tettnanger 5 min .25 oz Saaz 5 min 1 tsp Irish Moss 1.5q Wyeast Kolsch yeast starter Original Gravity 1.045 Terminal Gravity 1.008 Bitterness ~25 IBU Color ~4 L Rest 25 min at 135F, 25 min at 145F, 60 min at 155F. Entered in local competition, 2nd Place, 33 points average. Most negative comments were on DMS and astringency which relate to poor technique but not recipe formulation. The yeast flocculated very poorly, I had to filter. But some I did not filter did clear after cold lagering. This beer should be fermented at relatively low temps and lagered COLD. Came out with subdued fruitiness, medium body, and dry crisp finish. Good luck! - ------------------ Allergy challenge ... sounds fun. You know, trying to make beer without barley/wheat/rye. Why not malt the corn (and rice??) and try to brew with that. Didn't we read this in a Zymurgy issue a while back? Anyone remember which issue? How about corn and rice with amylase and/or koji? - ----------------- BTW, if you haven't, try Anchor's Holiday brew. It's great.

Higher temperatures can cause a staining problem to surrounding wall areas. No rinsing necessary. Use daily to sanitize dishmachines and other equipment. Renew solution before amber color disappears. SANITIZING EATING AND DRINKING UTENSILS 1. Scrape and preflush utensils to remove excess soil. 2. Wash in a solution of 1/2 oz MIKROKLENE to 2-1/2 gals water (25 ppm tit I) or other recommended detergent. 3. Rinse in clean water. 4. Sanitize in a solution of 1/4 oz MIKROKLENE to 2-1/2 gals water (12 ppm tit I). Immerse all utensils for at least one minute. 5. Drain and air dry. When used as directed, MIKROKLENE complies with FDA Food Additive Reg. 21 CFR 178.1010 (b) (4) for sanitizing solutions which are not to be rinsed from food contact surfaces. DILUTION TABLE ppm titratable iodine 12.5 25 50 75 100 oz MIKROKLENE per 2.5 gals water .25 .5 1 1.5 2 note: 1 oz = 2 Tablespoonfuls or 6 teaspoonfuls - --------------------------------------------- end of clipping Sorry about the major bandwidth use but this is the word according to the manufacturers and many people have been asking/suggesting. -Lee Bussy leeb at southwind.net Wichita, Kansas Return to table of contents

Morris type temp. controller to operate either as an I/O card in a PC or thru a serial/parallel port on a PC? Also, I would like to add a temp readout on the monitor. I am adept at putting things together and weak on programming and engineering. I can't think of any reason this type of thing couldn't work, but I don't have any clue how to go about it. I would assume the simplest way waould be to replace the Pot with a circuit driven thru one of the ports. Any help would be appreciated, if some of you engineer types and programmer types have some ideas we should go to E-mail I suppose. Oh, yeah did I mention CHEAP!?

Date: Wed, 30 Nov 1994 20:35:31 +0800 From: bjones at bdt.com (Bob Jones) Subject: Long aerations I hear you people talk of long aerations. Well when I used to ferment in 5 gal carboys and aerated for more than a few minutes, I got foam out the top of the carboy like ice cream. I would have to shut the O2 off and wait for quit a while before turning on again. I finally started injecting the O2 in line on the wort traveling to the carboy. This helps until the liquid level rises close to the top. I now ferment in a 15 gal sanke and all this isn't a problem since I have about 4 gals of head space. So how do you guys & gals aerate for long periods if you use a 5 gal carboy? Bob Jones bjones at bdt.com Return to table of contents

The higher the gravity, the more compulsory it is! Aerating is dissolving oxygen into *cooled* wort at fermentation temperature (not oxidizing). At my homebrewery I have used the surest, purest and incontrovertibly fastest way: Pure clinical oxygen (in 5 litre pressurized containers) which I introduce into the wort sitting in carbuoy *through 0,2 micron membrane filter, which no known contaminant penetrates*. This is the sure and safe way of dissolving oxygen, and is widely used by brewin laboratories having same scale as we homebrewers have. My mashing & boiling capacity is max. 60 Litres (abt. 16 US Gallons). All the very best and Malty Christmas to all Ilkka Sysila from Helsinki, Finland Return to table of contents

Ok, now what im getting from this is, invert carboy, tap and drink. Ewwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwww! I dont know about the rest of you, but the LAST thing in the world I would want to do is INVERT my carboy after fermentation. The first few glasses of that stuff would look like MUD and taste like it too! Ok, you invert the secondary, or rack to a clean carboy. How do you carbonate it? I wouldnt think that it would be smart to prime and presureize a glass carboy. And where are you going to stuff it? I know MY fridge wont hold it. My beer fridge might not even hold it. To me, this looks like a marketing gimick... I think the $26 would be better spent on a used Keg and parts for it. Rob Return to table of contents

Ok, im curious if anyone has tried making a smoked beer. Ive got a ton of mesquite (sp?) wood chips left over from grilling all summer. Im curious how a dark beer, dark amber beer (not a stout), would be smoked. I dont want something overly bitter, im looking for something very smooth, that would compliment the smoke flavor, not confuse it. I dont want something overly hoppy that is competeing with the smoke flavor. I want the smoke flavor to show through. 1. How do I smoke the grains. I dont have a smoker, but I have a webber grill. Would like a low heat on the webber, with the grains on a cookie sheet do it? Do I have to get the grains moist? I have no clue as to how to smoke them. 2. What grains would be good to smoke? Rye? Barley? Malts? 3. I currently dont have a grain mill, can I smoke the precracked grains? 4. Just how much grain am I going to have to smoke? 5. Would running hot wort through the woodchips lend the right flavor? I could just run the sparge water through the woodchips, would act like a sort of filter. I think it would also be slow enough to extract the flavor from the woodchips. Anyone try this? (Beachwood? AB?) I kind of want to stay away from "Liquid Smoke", as this would lend the right flavor, I think its not what im shooting for. Id prefer a natural process over liquid smoke.

I couldn't get the bottles more than 3/4 full, and >foam began the minute beer flowed into the bottle. >I chilled both the bottles and the CBF in the fridge with the keg. >What's the trick to make this gizmo work? I have had great sucess with CP fillers. Before filling a bottle it should be pressurized to equal the pressure of the keg. The keg and the filler should have the same CO2 source. When the beer inlet valve is opened very little if any should flow into the bottle. To make it flow, some of the counterpressure must be released. As little of a pressure difference as possible while still alowing beer to flow will keep it from foaming. When the bottle is full, stop the beer flow and then bleed off the excess pressure. If you have a pressure gauge on outlet side of the CP filler it will make things faster. It will take about one minute to fill a bottle. With practice it will get faster. Also the be certain that the beer that you are tring to bottle is not over carbonated. If it is over 3.0 volumes it will be very difficult. Also I noticed a post about hopping rates and the effect of temperature on hop isomeri- zation. It was mentioned that supposedly only heat is a factor in these reactions. However I have observed situations which would indicate that factors other than boiling alone can be effecting hop reactions. micah millspaw - brewer at large - ------------------------------ Return to table of contents
Date: Thu, 1 Dec 94 08:23:04 EST From: u2rg9red at hanover-crrel.army.mil (ROBERT E DAVIS ) Subject: foam Grettings to all in HBDland, I sent a friend of mine parts from the HBD discussion on foam for his input. He is a molecular physicist, working as a post doc in the Chemistry Department at Dartmouth input. He is quite a fan of my home brew, and a knowledgable guy to boot. His comments regarding the foam/protein discussion: All very interesting stuff, though the info in these notes is a little confused. OK proteins are indeed long chain molecules made up of amino acids. In their so called "native conformation" they are folded up into a well defined compact globular structure (generally with the hydrophobic amino acid residues buried in the core and the hydrophilic ones out on the surface). Most proteins are easily denatured by mechanical agitation, changes in pH, or changes in temperature. A denatured protein takes up a so called "random coil" conformation. The formation of foams from denatured proteins is indeed due to the interplay between the hydro-phobic/philic units. If there is some reasonable segregation along the backbone of such units then the denatured protein can act as a surfactant (such as a common soap). Surfactants migrate to the air/water interface and their presence dramatically reduces the surface tension of this interface allowing the ready formation of bubbles and foams (which have a SL of surface area). Now, the problem w/ denaturation vs. time. Contrary to what is stated in the discussion, MOST proteins DO NOT return to their native conformation after being denatured. OK, you might not think this is a problem since if they are in solution, whether denatured or not, they can still act as surfactants and create foams, right? NO, THIS IS ABSOLUTELY WRONG!!. Proteins in their native conformation are wicked stable as a function of time (assuming you don't perturb the solution so as to cause denaturation). Denatured proteins, on the other hand, do not fare so well. They have a problem of AGGREGATING with each other in solution (i.e. they tend to stick together). When this happens on a large scale you get what is known as FLOCCULATION - a very "wispy" type of precipitation. Anyway, once the proteins aggregate, whether they stay in solution or precipitate out, they will no longer display the surfactant type behavior necessary for producing foams. So the simply stated conclusion is that yes you do in a sense "use up" the proteins in the foam formation since once denatured they won't remain in a nice unaggregated form for a very long period of time and once they aggregate they're out of commission as far as foam formation is concerned. Re the guys comments about polystyrene (PS). The backbone bond in PS is made of C-C bonds of course while in proteins you have both C-C bonds and amide (N-C) bonds. Anyway you're not likely to "break" proteins by shaking the solution, you'd need a lot more shear than that. Of course PS does not fold up like a biological protein, its normal conformation resembles a denatured protein (i.e.. random coil). One other point that's relevant. In your beer wort and what not you have a lot of stuff floating around from the live "bugs". When you kill these bugs or as they die their cell membranes will lyse (break open) releasing all the stuff inside which will include a lot of protealytic (sp?) enzymes - these are proteins which chew up other proteins, so you might get protein degradation just due to the presence of these protealytic dudes. This would be a degradation that is to some extent constant in time. ******************** Bert Davis Cold Regions Lab Hanover, NH Just a dorky ol' Xtract brewer tryin to keep his head...

That brought back a memory of my own. A few months back -- possibly in the summer, I was talking with the people at that store too. I noticed that they had replaced their JSP Maltmill (tm) with a stainless steel Glatt. So I asked them about it. They said that the Maltmill wasn't working very well for them. The words 'slow' and 'unreliable' came up and they found the new stainless steel Glatt Mill to be superior in production and quality. Now it's very possible that they had a bad mill, and I don't know not having owned or used a Maltmill. However, it's gone and they replaced it with a Glatt -- and it's been there ever since.
