---------------------------------------------------------------------- Date: Tue, 15 Nov 94 15:20:14 EST From: Nancy.Renner at um.cc.umich.edu Subject: PET bottles, sparging end point, swollen extract cans, very fresh extract (From *Jeff* Renner) About PET (plastic) bottles. The local homebrew shop thinks these are the greatest thing since sliced bread. They sell 16 oz (or maybe 0.5l?) brown screw cap ones for $10/24 (+$0.79 for caps). The manager has abused these by way overpriming and all he got was a swollen bottle, not a bomb. He even boiled one. He just got a 4 oz. bottle! He likes them because they're light, unbreakable and cheap. The local fraternities are prohibited (by insurance?) from having glass at parties, so I'm thinking of brewing up something with my son so they can be exposed to something better than megaswill lite. Of course, since some of his brothers seem merely to want to be able to puke for less than $4, this may be casting pearls (or perles) before swine. *** Harry Covert wonders when to stop sparging. Someone (forgot who) posted a few weeks ago to stop when you get a perceptible color change. That's a little early! I go to 1.006-8 or so as long as my pH stays below 6, which it always has, so that I don't even check it anymore. I do taste these late runnings, however, just to make sure they don't taste astringent. Just watch your water chemistry - low bicarbonates and high enough Ca for pale malts, and enough bicarbonates for dark malts. I'm lucky. I can boil my bicarbonate water and add back CaCl2 (~1/2 tsp./5 gallons of water, Al) or CaSO4 for pale lagers or ales, and just use the water as is for dark beers. I'm sure I could use boiled and decanted water for Pilsners with a long acid rest, but I haven't. *** On the Judge Net Digest, there has been a brief discussion on "extract tang," which I suggested might come from old cans of extract in which there has been slow biological activity. I have tasted off flavors, especially in swollen cans, and, years back, in extract that was bulk packaged in plastic 1/2 gallon jugs. This prompted BrewerLee to repeat what was posted here some months back, that cans can swell from crystallization of the sugars. That may be, but I have certainly seen it with the production of gas and off flavors in extracts that were creamy smooth, i.e., no crystals. I have a few cans of old Premier in the basement that are quite swollen. (Someone got them from a warehouse in Detroit where they were being thrown out and brought a couple of cases to our beer club when I hosted the meeting, and these were left). The last one I opened was uncrystalized but gassy and had a sour, cooked cabbage flavor. It isn't fit to use even in dark, sour rye bread. *** This brings up something that I hope isn't seen as commercial. I just opened a can of Mahogany Coast pale extract that really smelled like fresh, malty wort! I can't claim to be completely uninvolved since the owner of G.W.Kent is a friend, (this is a private label of theirs), but that is my only connection. It seems that it is selling so fast that they can't keep it in stock. They have brought in two shipments since the brand's introduction (this summer?) and they had to wait for it to be produced before it was shipped, hence its freshness. Of course, there is no guarantee that it will be fresh down the pipeline. *** DonBrew says: >I found with my Corona that the solution is to hold the bottle tightly >with my left hand and actuate the lever with my right hand <snip> I've been wondering what to do with my old Corona since I switched to a Malt Mill! ;-) *** Thanks to all who have been signing with their locations. I've gotten several private email messages agreeing that this is useful. It looks like a trend. Jim Doyle details his location all the way out to "The Eye of God," but no city!

Lenzini" <jlenzini at mail.more.net> Subject: coriander/cilantro - used carboys I've been following the current thread concerning coriander in beer. Although, I've never tried using it, I've been tempted since reading about it in Zymurgy. I like using it as a spice on food and have grown my own. I also like cilantro (the leaves of the coriander plant - or is coriander the seeds of the cilantro plant) and was wondering if anybody tried using that in their homebrew.

Mutation should not be any more of a problem at 70F than at lower temperatures. I would be concerned about REALLY high temps, say, in the high 90's. >1c. Will my yeast go thru temp shock or will they be innured to that because >they have supposedly undergone post-krausen hibernation? You'll likely have temperature shock if you toss your 70F starter into 50F wort. Ideally, you would like to slowly lower the temperature of your starter down to 50F-55F when it begins to complete it's fermentation. Then you can pitch into 50-55F wort without temperature shock. Another method (which can give you some unwanted fruitiness) is to pitch your 70F starter into 70F wort, wait for fermentation signs and then slowly cool your fermentor down to 50-55F. You do want to wait till post-kraeusen to pitch because this is the time at which the yeast have the highest level of glycogen stored up. Incidentally, 1 quart is slightly on the low side for a lager -- ideally, for a "normal" gravity lager (12P (1.048), if I'm not mistaken) you want to pitch 2 liters of starter for a 5 gallon batch (you can pour off much of the spent starter wort). For higher gravities, you want to increase pitching rate. There is a formula, but I don't recall if it was in Noonan or Hough. Al. Return to table of contents
Date: Tue, 15 Nov 94 15:58:37 EST From: JULIO CANSECO <JCANSECO at UGA.CC.UGA.EDU> Subject: bottling tip Fellow homebrewers: As a new homebrewer I have enjoyed the amount of information available in the HBD. I have shared some of it with my fellow club members, most of us newbies. Here's my $0.02 worth in return. At our last meeting someone showed us that if you use 1 1/2 or 2 inches of plastic pipe when bottling instead of the most typical 3 feet and attach it to the spigot and then secure your bottling wand to it ( the one with a spring valve ) you end up with a stationary bottling wand that's hands free. This allows you to manipulate your bottles more easily all by yourself. I am sure this no news to more experienced brewers but may be of some use to other newbies.

Date: Tue, 15 Nov 1994 22:23:11 -0500 (EST) From: Craig Mcpherson <craigm at helios.cae.ca> Subject: Alcohol & Body (fwd) - ---------- Forwarded message ---------- Date: Tue, 15 Nov 1994 22:03:18 -0500 (EST) From: Craig Mcpherson <craigm at helios.cae.ca> To: Chris_Cesar at qmgate.arc.nasa.gov Subject: Alcohol & Body The following reply was sent mailed to Chris_Cesar in response to a post in Homebrew Digest openly wondering how it is that his beers come in just under 5% and yet are full in body, while Bud comes in around the same and is lacking in substance. I think the answer lies in "heavy gravity" brewing. High grav brewing is carried out by most of the major North American breweries in order to maintain both a "consistent" product and keep costs under control. Note I said "consistent" and not "good". For example, I live in the great northern tundra of Canada (yeah yeah, I have to fight off eskimos on the way to work each day). Anyhow here Molson's brews a product called XXX (triple ex) at 7.3%, this in turn gets watered down (literally) to form Molson Export Ale at 5%, and yet again to make their light beer (Canadian lite comes in at something like 4%). Brewing this way doesn't have to yield crap beer. In fact many microbreweries and some quality European ones do this as well. They also do some "tweaking" of the product and its flavoring as well along the way. One local micro here (in Quebec) bottles a most wicked wheat beer called "La Fin de Monde" (the end of the world) which is much like a dense Celis white from Texas - in fact Pierre Celis gave them the recipe. This beer clocks in at 9%, and they also "cut" it with sterile water and perhaps add some spices to create their Blanche de Chambly line of wheat beer at 5%, almost identical to the Celis white. This beer talk is all incredibly regionalin nature. No doubt the same is carried out by the majors and minors where others live. craigm at helios.cae.ca Return to table of contents

Last month I received a six'er of bier labeled: OKTOBERFEST German Styled Harvest Beer from teh Buffalo Brewing Company in Lackawanna, NY. It is bottled conditioned as evidenced by the scant dregs. The label gives no hint of the ingredients. Now I lived in Germany for over 8 years and drank, and drank, and drank beer. While I am not a fan of weizen, esp hefeweizen, I could stomach the krystalweizen, but I don't think I ever tasted a "harvest beer". This stuff is sour and not at all palatable. Is this potentially infected or is it supposed to be sour? Anybody want it? Four bottles left. E-mail seems most appropiate unless some of the masters think it deserves public discussion.

Adjuncts, adjuncts, adjuncts - -------------------- Mail Item Text Follows ------------------ To: I1010141--IBMMAIL From: Bob Paolino Research Analyst Subject: RE: Swill alcohol levels. Adjuncts, adjuncts, adjuncts Subject says it. You know those ads that say "More of what you want, less of what you don't"? Answer to #1: alcohol. Answer to #2: flavour, body, hops. I've done a 1.024 beer that had more flavour than Buttwipers/Miller/DogStyle et cetera. But, of course, the swill factories would never be able to sell a beer with 2-2.5% alcohol. That's why they proudly use the finest corn and/or rice. If you use something that ferments almost completely, you get the extra alcohol without having to worry about adding any of that nasty beer flavour. Some people ask me why I pay $6/sixpack for beer. I tell them it depends what you want, and that I probably spend less on beer than the swillers. I can have a couple of real beers and feel satisfied, whereas if I drank the $3-4/sixpack swill, I wouldn't feel satisfied even after six, just drunk. Now tell me who's buying the more expensive beer--even if you ignore the cost of feeling lousy and doing stupid things.

Date: Wed, 16 Nov 1994 8:16:09 -0500 (EST) From: "Rick Gontarek, Ph.D." <GONTAREK at FCRFV1.NCIFCRF.GOV> Subject: sanitization, yeast culturing/freezing Hello everyone. Listen, would someone please tell me how to brew beer? Thanks. Seriously, there has been some discussion of late regarding modes of sanitization of bottle, carboys, etc. Every brewer has his or her own personal methods, but I'd thought that I'd share mine. With regard to bottles, after I drink a brew, I rinse the bottle with hot water and then set it aside. When I have two cases of clean empties, I hit 'em with a hot squirt from my tap using a bottle/carboy washer (this is only about $9.00, and as far as I am concerned, is one of the most useful additions to any home brewery), then I put 'em in my dishwasher. I run the dishwasher without any detergent, and set it to heat dry. This is done just prior to my bottling session. After I rack my beer to the bottling bucket, I open the dishwasher a bit to let out the scalding steam, and with clean hands I take about a dozen or so bottles out at a time, let 'em cool for a few moments, then I fill 'em. If you find that you have inadvertently left your bottles without rinsing out the dregs, you will have a nice thick mat of green fuzzy white hairy beasties growing in the bottom. In this case, I'd recommend that you soak the bottles in a bucket of hot water and a few ounces of bleach. Then rinse the bottles well (very well), and proceed as above. To clean my glass carboys, I rinse them briefly with the bottle washer (gotta love that thang), add a few ounces of bleach, and then fill it with hot tap water. After a day or two, I empty the carboy, and rinse it really well, put some aluminum foil on the top, and store it until I need it. For plastic buckets/fermenters, I have found that 70% ethanol (ethyl alcohol) in a small spray bottle works wonders. I merely rinse the bucket with hot water, then give it a good once-over with the ethanol, then I wipe the inside dry with a paper towel. Ethanol is used by many homebrewers, but I highly recommend it for everyone. Be careful, though, because it's highly flammable. Using these procedures, I have *never* (in several years of brewing) experienced an infection of any kind (knock on wood, now that I've jinxed myself). The dishwasher is great. I am a scientist, so I have access to an autoclave. I used to autoclave my bottles, but I found that some became weakened after repeated rounds of autoclaving. Anyway, this is some advice from someone who is happy with his technique. Someone asked about freezing down yeast. This method is for those with lab facilities (probably not many of you, oh well). Whenever I buy a new yeast strain, a streak a bit out onto a sterile agar plate to get isolated single colonies (a la Yeast Faq). These single colonies are then grown in several milliliters of sterile beer wort until it ferments out. The yeast slurry is then mixed with an equal volume of 30% sterile glycerol, apportioned into sterile tubes, and then kept frozen at -70 degrees C. About a week before I brew a batch, I thaw a tube (about 1 ml), and innoculate a 10 ml sterile starter. After two days, I innoculate 300 mls with the yeast from the 10 ml culture. After about two more days, it's ready for pitching. Anyway, the point is that a final concentration of 15% glycerol is the standard microbiological procedure for freezing down bacteria and yeast. Yeast kept at -70C are viable (in my experience) for several years. I don't know about if they're kept at -20degrees C, but I do know that your home freezer is not cold enough to freeze the yeast/glycerol. One last thing (promise). I am making labels for my Christmas brew using Canvas on my Macintosh. Does anyone know where I can get Christmassy clip art (like at some ftp site on the net)? I really don't want to purchase a whole set of clip art, but I need something (like a Christmas tree or a wintry scene or Santa Claus or something) for the center part of my label. If anyone has a clue, I'd be greatly appreciative. Ta-ta for now. Enjoy your beer!!

Does >anyone have any experience with this? Is a deep freeze too cold? How >long does the yeast remain viable? I am a microbiologist and the glycerol method is one that we use to store yeasts and other fungi in cold storage. The yeasts are kept at -80C/-62F or in liquid nitrogen vapor (-150C/-238F) for years without any significant loss of viability. I believe refrigerator freezers are somewhere in the neighborhood of -17C/0F and should last at least a year without dying. The usual rule for freezer storage of microbes, the colder the better. When bringing them out of storage, warm the container with your hand and then thaw them quickly with warm water. Our other method of storage is freeze-drying but I don't think many homebrewers have access to a lyophilizer. ;-) Pat Humphrey Future Homebrewer Return to table of contents

Its a simple proportion: 4 * (1.152) + 11 * (1.0) = 15 * OG that is you mixed 4 gallons of 1.152 wort to 11 gallons of water (SG=1.0) to get 15 gallons of dilution with specifig gravity OG. OG=1.041 in your case. Maybe this problem should be posed in a grammar or high school freshman algebra book to keep students from saying that they'll never use algebra so why should they learn such useless stuff.

And to think that I knocked one witbier at the Belgian Spirit of Beer contest for having 'too much coriander'. I hope it wasn't submitted by Chuck Cox. By the way there were some excellent homebrewed whites entered in the contest. Maybe Pierre is getting scared that he may have some competition soon and is no longer giving out his "secrets" on brewing this style. Dan Foster asks: >We brewed a double batch of Mountmellick Irish Stout (extract) last night. >Both batches used identical ingredients and procedure. Starting gravity for >the first batch: 1.026. For the second: 1.042. I forgot to measure the >gravity of the first batch until 45 minutes after we pitched yeast. Is that >responsible for such a low OG, or did something else go horribly wrong? This is a common misreading due to stratification of your wort - the more dense stuff will initially settle to the bottom and lighter stuff will be on top. If you took your sample from the top of the fermenter after letting it sit for 45 minutes and didn't stir, you simply measured the OG of the lower density stuff on top.

The recipe for the wit that took best of show at the Spirit of Belgium is posted below. You'll notice that the amount of coriander is only 5 grams per 5 gallons, but half is boiled for 15 minutes and the rest is added to the secondary. Although I haven't received the judges' comments back, this tastes about right. I've also noticed that the flavor is more intense in the kegged portion - it seems to mellow in the bottle. The coriander should be a subtle flavor that is balanced by yeast phenolics and bitter and sweet orange peel. Lactic acid or lactobacillus should be added to cut the sweetness, otherwise the wit would be cloying. Here's the recipe: 5# D-C pilsner malt 4# raw wheat flakes 0.4# rolled oats Step infusion mash: Dough-in at 110, hold for 10 minutes and acidify the mash if the pH is above 6. 30 minute protein rest at 128 F (normally 125 F, but I wanted to get more cloudiness), followed by a 60 minute starch conversion at 152-155 F. Mash out at 170 for 5 minutes, and sparge to a volume of 6 1/3 gallons. I boil off a little more than a gallon in my set-up and end up with 5 gallons with a gravity of 1.052. Hop/Spices: 0.9 oz. East Kent Goldings (60 minutes=20 IBUs) 0.25 oz. Saaz (15 minutes) 2.5 g. freshly ground coriander (30 minutes) 1 oz. organic orange peel from Israel (15 minutes) 2.5 g. freshly ground coriander (secondary) Force chilling, pitched a 1 pint starter of Wyeast 1214, and fermented at 62 F. I think I'll use a more phenolic yeast in my next batch. Rack to the secondary after 5 days and allow to ferment out. Here's the key ingredient: when bottling, add a 50-100 ml starter of lactobacillus, along with 3/4 cup of priming sugar. The acidity gradually build in the bottle or keg, and is noticable after 2 weeks. If you don't want to bother with the bacteria, add USP lactic acid to taste.

These are the people that sell hops for $3.85 a *pound* and up. Their number is in Brewing Techniques. They don't pay me. I'm not even a satisified customer yet! But I probably will be when those 4 lbs of hops show up at my door. *** Mike Montgomery was looking for the AHA American IPA style. Looks like they have one. This is from the AHA guidelines from Spencer's Beer Page: >6. American-Style Pale Ale > >a. American Pale Ale > Pale to deep amber/red/copper. Low to medium maltiness. High hop > bitterness.

Date: Wed, 16 Nov 1994 12:07:16 -0800 From: ruderman at esca.com (Curiouser and curiouser...) Subject: Low pH Barley Wine Over this past summer, when the sun actually shone in Seattle, I made a 5 gallon batch of barley wine. The original potential alcohol reading was about 14%. For the primary fermentation, I pitched a dry Pasteur champagne yeast along with a British ale yeast (Wyeast). After the third fermentation (about a month after the first fermentation), I noted that fermentation had all but stopped with a P.A. of 7%. I repitched some champagne yeast, but there was little improvement. After two months, and a final P.A. of 6.8%, I gave up and bottled my brew. Since then, my eyes have been openned and the cause of my problems (and really sweet barley wine) was due to a low pH (less than 4). My question is, if I pour all my bottled barley wine into a pot, bring it back to a boil and add in some calcium carbonate (I think that's the right stuff to raise the pH to 4.0+), chill the wort, put it back into my carboy, and pitch some more champagne yeast, will fermentation resume? Has anyone tried this sort of thing before and does it work (or does reboiling the batch wreck it in some manner)? Any thoughts and insights would be appreciated.

Remember, proper O2 injection of wort results in ~8mg/L DO (dissolved oxygen). Bubbling pure O2 through chilled wort for 20-60 min will maybe come close to this amount.

Date: Wed, 16 Nov 1994 20:58:54 -0500 From: CliffR3500 at aol.com Subject: Coriander Hello All, I have been following with interest the discussion about Coriander. I happend to have been brewing two batches of my house bitter on Saturday and Sunday when I started reading about corianders brew magic. On the fly I conducted a minor experiment by adding about 6 seeds to the mash and about 1/2 an ounce to the last ten minutes of the boil of one of the batches. Other than that both batches are as identical as I can manage to make them and are fermenting happily side by side. I'll post the tasting results in a couple of weeks. Until then, I was hoping to get some more information on this wonder seed. The article that started all this commotion made some pretty sweeping generalizations that I was hoping to get some comment on. Namely: >I believe adding a few coriander seeds to the mash helps >reduce the effects of hot side aeration. I also believe using >coriander in the boil helps slow the process of oxidation in >the finished beer. >My coriander beers tend to clear quickly and don't develop >chill haze. It seems to me coriander has preservative and >fining properties. The claims about its contribution to the flavor and character of the beer I'll proabley be able to deduce on my own (Though I would be interested in any discussion on this topic as well!), but I was wondering what other coriander brewers out there thought about the above claims.

In laboratories, yeast is commonly frozen in a final concentration of 25% sterile glycerol. These are frozen at -70 to -80 C. At these temperatures, the yeast cells will stay viable almost indefinitely (as long as, once frozen, the vial is never thawed). Strains are "revived" from the frozen state by scraping a bit of the frozen mixture off of the top and streaking it on an agar plate. I don't have any experience trying to maintain frozen stocks at temperatures higher or lower than the range above. However, I don't think a common household freezer (about -20 C) will do, especially not a frost free freezer, which goes through constant freeze/thaw cycles.

It is a clarifying/fining agent that meets the rein criteria >to "work mechanically or by absorbing". So that clarifying must be why >those cloudy wit beers taste so good! ;^) Actually, Carl Saxer wrote that, in his experience, beers that he has made with coriander cleared *faster*. The clearing of a beer has to do with yeast settling and nothing to do with the permanent haze of a witbier. For all you beginners out there who are running to the grocery store looking for coriander to put in your Oktoberfests: don't expect miracles. This HBD thread is a joke... Chuck and a number of others poking fun at Carl's rather zealous excitement about coriander. The Zymurgy article does imply that coriander can help add that "elusive" maltiness in an Oktoberfest, but as I read it, Carl meant this tongue-in-cheek. Too bad it's not true, though -- I wouldn't mind it if a few drops of coriander tea added to a paper cup of Miller turned it into Spaten Helles... Al. Return to table of contents
