I had only one batch during my extract days that carmelized. I had left the burner on while I poured in my extract. What I recommend that you use: 1. Get a Pizza stone to put on the burner to even out the heat from the electric coil. 2. Once your water get's near boiling, remove from the heat or turn it off, THEN put in your extract. STIR like crazy to get it to mix in. 3. Watch your boil, stir from the bottom almost constantly to keep the sugars supended. As for your other questions: 1. Possible but try a stone first. 2. Heavy pot ware is not absolutly messary. This will prolong the heat to boil and the cool down. 3. Yes, possible. I have used 5 gallon pots during my extract days. Now I used a 10 gallon boiler. 4. No the rolling boil is what you need to get the best out of your hops. 5. Your choice... 6. Had it, cured it. Comment, Read the books, Miller and Papazan are favorite writers on brewing subjects..

I have seen several recipes using chocolate and roasted barley and they all use different amounts. The style description at the Brewery's Library states that it should have a slight roast flavor and a deep ruby red color. My question is, how much of each should I use of each for a 5 gallon batch?

I brewed two different beers, one a export type stout, one a strong ale. The stout had very little kreusen; the strong ale practically blew the top off the fermenter. I ended up removing even the blow off tube and letting the foam spill out (I guess this is "open fermentation") Details: Stout: 70% Marris Otter Pale Strong: 87% M-O pale 15% Crystal 200L 7% Carapils 7.5% Roasted barley 3% Chocolate 7.5% Black Patent 3% Peated Specialty malt all Hugh Baird, I think OG= 1.074 FG=1.020 OG: 1.078, still fermenting Single infusion for both 65C/150F for 1.5 hours. Yeast for both was dry Danstar Nottingham, pitching rate was the same, temp = 21C/70F, both beers primary fermenter was a plastic bucket with 20% headspace. In the future, how can I know what beer will ferment violently so that I can plan accordingly? In my situation I often have to leave newly brewed beer unattended for long periods; so I'd like to know how to set up the primary before I leave. BTW, these were 1 gallon test batches; stout total grain = 4 lbs, strong = 3.7 lbs. I know my efficiency is lousy; In this "mini mash" setup my sparging is too fast.

I have been using the same foil airlock technique when I brew lagers. I place one layer of sanitized foil on my primary fermenter right after pitching the yeast. When fermentation activity picks up, I replace the foil with a conventional airlock. I started doing it because of a few instances of "airlock suck-back" caused by lager yeast's longer lag times and cooler fermentation temps.

This annual competition is open exclusively to women homebrewers, regardless of where they live. The 1997 Queen of Beer is Nancy Sampson of Orlando, Florida. Her "Predator Pale Ale" took the Best of Show honors. Congratulations, Nancy! The results have been tabulated and are listed at our website at http://haze.innercite.com. In this, our fourth year, we had the largest number of entries ever! I asked one of the Best of Show judges for their opinion of the quality/caliber of beer(s) submitted for this competition and the reply was "Overall, I think you had a better quality of entries than I?ve judged in 1st round Nationals or State Fair, and maybe the best overall quality of any competition I?ve judged at." You go girl!!! Thank you all for your entries and making this competition possible. Remember, it's not to early to start brewing for next year!.

Date: Fri, 31 Oct 1997 11:36:10 -0600 (CST) From: Samuel Mize <smize at prime.imagin.net> Subject: Wort-scorchin' caramel crisis (Wort caramelization) Greetings to all, and especially to: > HOMEBREW Digest #2545 Fri 31 October 1997 > From: S&R Moed <bina at idirect.com> > Subject: Wort caramelization? ... > Any time I have boiled a wort from extract I always end up with a > bitter/sweet taste which I attribute to caramelization. ... I have been > boiling 4 pounds of extract in 2.5 gallons of water, then topping up to 5 > gallons. Brewers sometimes scorch wort, although seldom badly enough to toss the beer. You may be very sensitive to the taste. Thin enamel pots are especially prone to this, but can be used with just a little care. Many of us (including me) use enamel pots on electric stoves. Once you've fixed the burning problem, you should get significant benefits in clarity and flavor from boiling your wort, so I strongly recommend you try again with these suggestions. There are several suspects here. Most likely, you need to raise your pot. Also, let's check your exact procedures. Finally, I'll answer your specific questions. RAISING YOUR POT With a thin pot sitting on the element, you have in effect a chunk of red-hot iron touching your wort. The easiest fix is to raise the pot a bit off the element -- maybe 1/8 to 1/4 inch. With the pot lifted, you are using radiant heat to warm the entire bottom layer of the pot. Some people get a "heat tamer" at a hardware store -- sounds good to me, but I have yet to find one. Some use an unvarnished wire hanger bent into a "V" shape to sit between the pot and the element. Or you can rest the pot on supports spaced around the element. I do this with mason jar rings, but my elements stick up above the stove top -- if yours are flush or recessed, use something shorter. You get less heat this way, since you aren't getting direct heat conduction from the element to the pot. Most stoves will still have plenty of capacity for a partial boil. Another benefit is that home stove elements are NOT designed to be run at top power for over an hour without air flow drawing off heat. They are designed for smaller pans and shorter cooking times. Most canning pots overlap the element enough to close off air flow. So, raising the pot will reduce caramelization AND extend the life of your element. BOILING PROCEDURE Let's check your procedure. Do you: - Mix extract into tap water, then heat or - Bring water to a boil, add extract while boiling Either of these can burn some of the malt extract, because you get a thick layer on the bottom being directly heated. You want lots of water in there to moderate the heating of the extract, with convection currents sweeping the extract away from the heat source before it can scorch. The best procedure with extract is: 1) Bring water to a boil (de-oxygenates it, and heats it so the extract will mix well). 2) Remove from heat (or turn off burner and wait 10-15 seconds for the element to cool). 3) Add extract to water. 4) Stir thoroughly until ALL the extract is dissolved, and there is NO layer on the bottom. 5) Return to heat and bring back to a boil. If this describes your current procedure, I suppose you might be using too much heat (this would indicate you have one heck of a powerful electric stove). You want a nice rolling boil, where the fluid is stirring itself nicely -- but don't dump in more heat than it takes to sustain that level of boil. SPECIFIC QUESTIONS You asked: > 1.Could I be scorching the wort Yes, see above. > 2. Should I use a heavier pot? That would help, but raising it off direct contact with the element should give adequate results. Even if you get a heavier pot, raise it off the element. > 3. Could it be because the wort is to concentrated? Going to full boil would also help. I use a 33 quart enamel pot, which I got from Wal-Mart (sold as a tamale pot). I put this over two elements -- it doesn't quite cover them, which is good, and I get most of the heat from both of them. > 4. should I go for a gentle boil? NO. You need a "rolling" boil -- with convection currents firmly stirring the wort. If it's just bubbling, the wort won't "roll" away from the heat source, and you may get a static layer on the bottom being directly heated -- creating MORE caramelization. > 5.Should I use a propane burner? I doubt it would help, although it might heat the bottom a tad more evenly. Most people go to propane burners to get more heat, for faster or larger-quantity boils. > 6. Do any of you have caramelization problems? No one else in the history of brewing. I made all this up. :-) > If it's not caramelization what could it be? ... > Rob Moed > Oakville, Ontario, Canada.

Date: Fri, 31 Oct 1997 12:52:53 -0500 From: mjk <knoroa at rbnet.com> Subject: Adequate Ventilation New to HBD, 1st Post. Great stuff every day. Question about Ventilation: Having gone all grain, I've been banished to the unheated, detached garage for all brewing activities and am concerned about maintaining enough ventilation for my propane burner. Considered solutions are: (1) do all "burning" outside and worry about the hot-liquid-transportation factors, (2) brew with the garage door wide open and blow a window fan for ventilation and wear an extra pair of socks and sweatshirt, (3) brew with garage door partially open for ventilation and install a flue extending through the apex of roof (window fan as well) or (4) some contrived combination of the previous. Assuming the obvious safety precautions are taken (i.e. no gas cans, no oily rags near burner, etc.) what amount of ventilation would be prudent? Fermentation & Racking will be done in basement of house. Opinions appreciated. TIA. I'll have to work on my catchy & thoughtful trademark slogan... Mark K. Return to table of contents
Date: Fri, 31 Oct 1997 11:52:27 -0600 (CST) From: Samuel Mize <smize at prime.imagin.net> Subject: Save that moldy beer! I promised earlier this year to post the info from rec.crafts.brewing on saving beer that has started to mold in the fermenter. This isn't my knowledge, it comes from Rick Hawkins at IA State. Note first that people often ask on r.c.b if their beer is molding, and it turns out to be islands of very tight foam, not mold at all. If you DO have mold, here are Rick's directions: - -- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -- [This is combined from two messages by Rick Hawkins] Most batches with surface mold can be saved; but time is critical. By the time they drop spores, it is too late. Most surface mold is aerobic; it requires oxygen to grow. It gets some when you first put the wort in the fermenter, and a little more when you rack to the secondary. If you have a lot of headspace in the secondary (a couple of gallongs), they get out of control fast. - -- - - - -- An earlier version of these instructions have accounted for about 200 gallons saved--about half of those gallons were mine :) 1) act quickly. time is your enemey. 2) it is usally possible to salvage most of your beer if it catches mold. The point of no return is when the "floaters" drop "danglers", which is the mold "spooring". Prior to this, the mold is (mostly) localized at the top. Once they spoor, it's all over, and the sewer rats have a good night. 3) oxygen is your enemy. Most mold that bother homebrewers can grow only slowly without it, and grow rapidly with it. 4) if possible, keg. after sanitizing the keg, pressurize to 40psi or so, let set a few minutes, and release pressure through the safety valve or the gas line. Repeat twice. Rack your beer into it. If possible, siphon directly into the "beer out line" to minimize splashing, etc., and allow you to leave the keg sealed (you will need to release pressure frequently while siphoning. 5) if you can't keg, sanitize your bottles and prime each bottle rather than the batch (to avoid stirring and letting in more o2). Do not use a bottling bucket; this is one more chance to get o2. this is more important than clarity & sediment--do you want to be able to drink it, or do you want to look at it? leave minimal head space at the top of each bottle (again, minimizing o2). 6) when transferring, kiss off about the top 2" of your beer. While this is painful, it's better to write this stuff off than to risk getting the mold into the bottles. 7) if at all appropriate to the style, dry hop. Either an ounce or two in the keg in a bag, with weights to pull it down, or a 1/4" or so or a whole flower in a 22oz bottle (half this for 12 oz). This is a *heavy* dryhopping rate; scale back for stlyes that can't handle it. Dryhopping does two things: 1) some preservative effect, 2) masks mild off-flavors. (dry-hopping a keg can also give you a few more days if you get lactic; otherwise, there's nothing to be done for this plague. 8) drink it quickly; while you have alleveiated the problem enough to save the batch, you have not eliminated it 9) good luck.

Date: Fri, 31 Oct 97 12:54:47 CST From: jwilkins at imtn.tpd.dsccc.com (John Wilkinson) Subject: Wyeast 1968 Mike Rose wanted to know about the necessity for aerating and agitating wort pitched with Wyeast 1968. I use 1968 more than all the other yeasts combined and I never agitate. I do aerate or oxygenate very well at the start but not during fermentation. I pitch fairly large starters that have been stepped up about three times or reuse yeast from the previous batch. I usually brew three batches in succession so I can easily reuse the yeast. I merely siphon off the completed beer and pour the chilled new wort into the fermenter onto the sediment. I get 75% apparent attenuation with no rousing or oxygenation after the initial oxygenation.

TEED" <MS08653 at msbg.med.ge.com> Subject: Looking for burners .int homebrew at hbd.org Greetings folks, been spending my last few months building my rims system and am looking for a few items to complete my system. Hope some of you can help me locate a few things. I need a perforated false bottom that wont break the bank ( the rims already has.. ) to replace or cover the slotted manifold I am currently planning on using. The hole in the top of the mashtun is 12" round, so I need one that folds or can be cut and made to do so, or any ideas from the experienced. Will a slotted tubing manifold work well with a perforated metal 'cover' over the top of it? Since I already have a framework, I dont need the support of a complete cajun style cooker, all I need is a burner. Already have an lp regulator and such. Is there a source for just burners or a way to build one from readily available parts? I have built one burner from a water heater burner but dont feel it will work well for the boilpot, however it should work fine for heating the mashtun ( the flame tends to be closer to the edge of the pot than the center due to the diameter of the burner plate ). Any URLs to rims systems would also be appreciated. If I get a good supply I will compile and send up to the group if interested. Hoping to see my system up and running in the next couple weeks. Question on mills... Is there an advantage to getting the adjustable maltmill in regards to crushing unmalted wheat or other hard as nails grains? Using my corona I would start at a larger setting and do 3 or so passes progressively dropping the plate spacing. Or am I better off using the corona for the 'grinding' and a fixed mm for crushing malt? I thought for the difference in price that I would sell the corona and get an adjustable mm and be happier? Or would I? Thanks... Mike Teed ms08653 at msbg.med.ge.com Return to table of contents
Date: Fri, 31 Oct 1997 11:10:12 -0800 From: George_De_Piro at berlex.com (George De Piro) Subject: Re: Wyeast 1968 and rousing/aerating / Deschutes Yeast? Hi all, Mike has read that Wyeast 1968 (London ESB) requires agitation/aeration during the fermentation in order to achieve proper attenuation. He wonders about aerating it periodically until fermentation lock activity peaks. I just finished up a batch of ESB brewed with 1968. I spoke with a couple of people (you know who you are) about the merits/detriments of aerating once fermentation was going. In my opinion, aerating the ferment is probably a bad idea; it may elevate the diacetyl levels, but it will also hurt the shelf life of the beer. If you are planning on cask conditioning and drinking it quickly, that may be fine. If you are planning on having the beer around a little while, you may be upset by the cardboard notes that it will acquire after a short time. I don't think that oxygenating for 1 min. per hour until you see airlock activity is a good idea, either. You may actually achieve too much yeast growth, and an increase in off flavors, by supplying the yeast with that much oxygen. I found that simply pitching the yeast and oxygenating in the normal fashion (45 sec. blast for 4.5 gal. of wort) worked fine. I swirled the carboy a couple of times during the fermentation to ensure that the yeast stayed in suspension. That may not have been necessary (I didn't check the gravity during fermentation). By keeping the carboy closed during the swirling oxygen is excluded from the ferment. I should say that the beer is disappointingly low in diacetyl. I guess if I had let the yeast stay at the bottom, I would have gotten more, but attenuation may have suffered. I'll have to try it again... A related question: The ESB I spoke of was split into different fermenters. One batch was fermented with Wyeast 1968, the other with yeast cultured from Deschutes Obsidian Stout. They were fermented under the same conditions. The resulting beers are damn similar, and the fermentations behaved alike, too. Does Deschutes yeast = Wyeast 1968? Any knowledgeable opinions?

Date: Fri, 31 Oct 1997 14:37:29 -0500 From: "Jeff Johnson" <jdj at mindspring.com> Subject: Wit/Fruit Wheat Double Brew Hi all, My wife has been nagging me for a Georgia Peach Wheat beer for some time now. I also would like to make a Belgian Wit. Here's what I'm gonna do: I plan on brewing a 10 gallon batch in my 1/2 bbl brewery using the recipe below. I'll then split the 10 gal into two 5 gal batches. Recipe: 9 lb 2-row lager malt 6 lb wheat malt 3 lb flaked wheat 2 lb flaked oats Mash in at 122 deg F and hold for 20 min. Raise temp to 135 deg F and hold for 20 min. Raise temp to 153 and hold for 75 min. Mash out at 170 deg and sparge to collect 12 gal of sweet wort. Boil for 75 min using 15 IBU's of Tettnang and Hallertaur hops, and about 1 oz Tettnang finishing hops. In one of the 5 gal splits I'll ferment with Wyeast 3944 Belgian White yeast and at kegging time I'll add a "tea" made from 1oz. Curacao Orange peels and 1.5 TBLSP coriander seeds. In the other 5 gal split I'll ferment with Wyeast 1338 European Ale yeast (hopefully to leave some residual sweetness) and keg with 4oz of Peach Fruit extract. Granted the Wit will not truly be to style, but it should be close (maybe??). What do ya'll (using my Georgia accent) think?

I've recently brewed 2 barleywines (allgrain), and my extraction rates were well below normal. I am wondering whether the mash regime has anything to do with it, or whether I just did a poor job. I average 76% efficiency, but these batches came in at 61-62%. Here are the numbers - I'd appreciate any guidance HBDland can offer. The base malt was primarily marris otter crisp. both 3 gal batches. batch 1: 11 lbs 2 row, 11 oz caravienne, 7 oz munich I may not have hit these temps exactly - didnt keep very good notes. also, my thermometer broke, so I used a metal one of onknown accuracy. however, results for the 2 batches (second with a great thermometer) were nearly identical. lauter went fine, probably 1-1.5 hrs. l 25 minutes at 144F 60 mins at 155 15 mins at 168 batch 2: 11 lbs 2 row, 11 oz caravienne, 7 oz munich Here is how the (shagrin) mash went: overshot a target beta glucanase rest temp of 100 (probably not needed, but I hoped to reduce some teltale haze and increase the extraction rate (hah)). i hit 107. stired for 20-25 mins to lower the temp, ended up at 104. lauter stuck allot (i allowed the grain bed temp to fall too low i think), nearly 2 hrs total. overshot a target beta amylase rest of 144 as well. hit 147. 5 mins to stir/cool to 145, then 20 mins rest. raised to 154, 30 mins rest (temp dropped to 149) raised to 154, 30 min rest. dropped to 150-151 raise to 168, restt for 15 mins. The only good thing about the lower-than-target OG is that it is hoppier :-) -Tim Tim Fields ... Fairfax, VA tfields at his.com Return to table of contents

I can't shake loose the dough required for Volrath nirvana just yet and the publicans are pretty good at keeping track of their empty Sankeys, knowhatImean? Not that I would take one without permission. I can get the aforementioned 8-gallon job for about US$35 and am sorely tempted in the short run. Do they hold up for a year or two on top of 100,000 BTU's of propane? Can you drill them without major chipping to add a spigot? Are they too thin? They seem to be to me. Even if I don't go to all-grain right away, I do want to boil the whole wort.

What you really need to be concerned with is your wort stability. If you have bad wort stability then maybe you *should* be worried about 12 hour lag times or even 6 hour lag times. Hell pitch a gallon of yeast, that'll get things going quickly and cause those folks getting "long" lag times of 4-6 hours to hang their heads in shame. Before everyone sounds off about how bad 12 or even 24 hour lag times are, let me ask ALL of you: Have you ever done a wort stability test? Yeah...didn't think so. I have. In my brewery, oxygenated, unpitched wort has gone four days without ANY off flavors or fermentive activity when incubated at 80-90F. That being the case, I have no concern for long lag times because they *will not* be the cause of off flavors. I suggest periodically doing WST to ensure that your sanitation practices are up to snuff. This, if nothing else should allow you to *relax* about those "long" 12 hour lag times.

Obviously homebrewing's lots of work and complication in any person's life. Careless I may be in brewing techniques, but not lazy. Homebrewing amazes me in that there are so so many niches for our artful ness and creative energies. Some brewers are mechanical engineering wizards with RIMS etc while others have beautiful, creative labels. Some brew and brew old favorite recipes while others explore the outer reaches of ingredients and historical practices. Some have serving excellence with multi-tap arrangements in atmospheric pub-like environments served by St. Pauli girl wife/SO lookalikes while others craft beers artfully within existing beer style. Others practice the culinary arts to match beer and gormet foods. Some choose to be very social and share their brews with many guests. Some yeast ranch and or grow hops while others answer newbie questions on the HBD. Some search the world for the highest quality and freshest ingredients while other scrub bottles and fill and cap. There are many priorities to choose between. Am I lazy if some of the above are not emphasized in my brewing regimen? Theres lots of details and much to respect.

Date: Sat, 1 Nov 1997 11:26:21 -0400 From: ajdel at mindspring.com (AJ) Subject: water analysis John Kostelac asked about his water. Ordinarily I'd e-mail but I thought the barium level was interesting: >Aluminum .020 mg/l >Barium (the highest) .228 mg/l >Iron .080 mg/l >Nickel .020 mg/l The only two on that list of real concern are the barium and iron. Barium is pretty nasty stuff but this level is well below the EPA limit for drinking water of 1 mg/L (though it is a bit over twice the EEC limit of 0.1 mg/L). The iron is just below the 0.1 mg/L taste threshold which is the most brewers like to see. On to the more conventional stuff: >Constituent Units are mg/l unless otherwise noted >Calcium 33 >Magnesium 5 These represent moderate levels of hardness (82.5 mg/L as CaCO3 calcium hardness and 20.6 mg/L as CaCO3 magnesium hardness for a total of 103 mg/L). Unfortunately, it's not very much at all relative to the reported alkalinity. Kohlbach's residual alkalinity is about 230 mg/L for this sample. Light colored beers brewed with this water will not reach appropriate mash pH. Acidification, calcium supplementation or addition of dark malts to the grist will be required. >Chloride 62 >Sodium 108 Both high. The water (and beer) might taste salty. This is not a problem for many ales, however. One suspects that this water comes from a source adjacent to natural halite deposits OR that it is the results of measurements taken during the winter when salt is being applied to roadways. >Fluoride 0.5 Not a problem at this level. Well below the EPA limit of 4 mg/L. >Nitrate (as N) 0.11 Well below the EPA limit of 10 mg/L and not high enough to worry about bacterial reduction to yeast poisoning nitrite. >Sulfate 2 Very low. It's this low level of sulfate that allows the barium to be as high as it is. Sulfate will have to be augmented to lend authentic hops character to any ales. Gypsum is the usual choice and this has the additional benefit of increasing the calcium. Bumping the sulfate up an order of magnitude (20 mg/L) or 2 (200 mg/L) should lower the barium (by precipitating barium sulfate) by at least enough to get the level below the EEC limit and perhaps a good deal more. >Total Hardness/CACO3 102 See above. >pH 7.9 (no unit, of course) Normal for a highly carbonate water >Dil. Conduct(UMHOS/CM) 690 (no unit) umhos/cm (ususally listed as uSiemens/cm) is the unit. The TDS is about half this number >Tot. Alka. as CACO3 256 This is a lot of alkalinity. As we noted, the residual alkalinity is nearly this large because of the small amounts of calcium and magnesium. The saturation pH of this water is about 7.42 which, as it is less than the pH, means that the water is likely to precipitate calcium carbonate if boiled thus reducing this alkalinity somewhat but only to the extent of the calcium. The maxiumum it could lose would be 82 ppm as CaCO3 (and in fact it would probably lose less). Suplementation of the calcium with gypsum would then definitely be required. Calcium chloride could not be used as the chloride level is already high. >Bicarbonate 312 61*(Alkalinity/50) = 312 i.e. the alkalinity is mostly from bicarbonate. In fact it is a bit suspicious that the reported number came out exactly 312. The actual bicarbonate number will be a little less than this at pH 7.9. >Carbonate 0 At pH 7.9 the amount of carbonate is unappreciable >Dissolved Solids 367 Note that this is about half the conductivity. >P. Alkalinity / CACO3 0 P alkalinity is the amount of acid required to LOWER pH to 8.3 If the pH is less than 8.3 to start with the P alkalinity is, obviously, 0. This water isn't too bad for brewing as long as you stick to ales and supplement the sulfate. It's going to take some fiddling to do lagers (and some ales such as wheat beers) sucessfully though. The main problem is in the high alkalinity relative to the calcium with secondary problems being in the high sodium and chloride levels. Numquam in dubio, saepe in errore. Return to table of contents
Date: Sat, 01 Nov 1997 10:11:13 -0600 From: Eric Pendergrass <eap at netdoor.com> Subject: When to transfer to secondary? Greetings, I've been reading the HBD on and off for about 3 years, and I have some questions about a lager I'm brewing. It's an extract bohemian pilsner using Wyeast 2278. It has been fermenting at the same rate (about 4 bubbles/min. at 46 degrees F) in my fridge for 7 days, and is past "high krausen". I feel like this rate is healthy for such a low temperature, and considering I used a large starter (6 hr lag time). I plan to lager at 35 F for several weeks once fermentation stops. Two concerns I have regard oxidation and diacetyl/off-flavor reduction. First, would it be better to go ahead and rack to the secondary while a significant amount of CO2 is still being produced (in order that a CO2 blanket would more quickly form over the racked beer in the secondary, preventing oxidation)? Second, by racking the beer off the flocculated yeast this early would I reduce the capacity of the remaining yeast to complete fermentation and subsequent lagering? Isn't off flavor reduction a function of the number of yeast present during conditioning, to a certain extent? When should I rack this beer if it's still actively fermenting? On a related note, I have noticed a rotten egg smell in my fridge, and I know this is oft encountered during lager fermentation. Is there anything I should or shouldn't do in order to ensure it does not end up in the final product? Eric Pendergrass eap at netdoor.com Return to table of contents
Date: Sat, 1 Nov 1997 11:22:46 -0500 From: "Michael Gerholdt" <gerholdt at ait.fredonia.edu> Subject: Extracting pleasure Thomas Lowry considers our conversation about the possible qualitative differences between brewing from previously extracted sugars and from freshly extracted sugars "bickering" and "fighting among family members." I certainly don't see it that way, and don't consider expressing my opinion to be tatamount to 'selling us a new religion.' Because I know how people tend to react and over-react to the written word, I was pretty careful (or so I thought) in how I stated my opinion. But obviously it was not careful enough. Most homebrewers are extract brewers. I don't consider them lazy. I know that my all grain beers taste better than my extract beers. I have made extract beers recently with a friend who's learning, and I certainly didn't try to make worse beer just because it was extract. It just doesn't taste as good, IMHO. Thomas, your comments here: "On the other hand Michael, if mashing and then brewing with all grain brings you to the point that you say 'to consider making an extract beer with its savings in time and effort would seem like something of a luxury - a self-indulgence.', then I say, it's time you take a vacation." are unwarranted. I make all grain beer because I want to. Making extract beer is not what I want to do. I think you should examine your motives when you start telling people to take vacations. My post was a considered and honest opinion. Your comments above are inflammatory. Stick it in your lauter tun, buddy! <g> (Sorry, forgot - you don't have one! Well, be creative . . . <g>) LISTEN with a friendly ear: I think it takes some _very_ fresh ingredients, which are not always easy to come by, to make an extract beer that can stand up to an all grain beer. With properly stored grain, I have fresh ingredients on hand at all times. It does take longer to brew, but I don't have to worry about freshness problems. Also, the ability to nuance a recipe is so much easier with grain. A pound of Munich, half a pound of wheat, a quarter pound of Special B - compiling a grain bill with some malt complexity is utter simplicity. To do this with extracts is possible (almost), but it is expensive; and freshness is even more of a factor when you are dealing with specialty grain extracts than when dealing with base malts. I don't think it is the skill of the brewer as much as these considerations which make the difference in quality between most extract based brews and all grain brews. AND That's about all I have to say about the difference between brewing with commercially extracted and condensed sugars, rehydrated (oh yes they are, Thomas, by the homebrewer), and brewing with freshly extracted sugars from the grain. Grant Knechtel quotes me before saying : "To criticize anyone for omitting a step is a little hypocritical - obviously few of us have the time and space to *completely* make our own beer." I'd ask you, Grant, to re-read my post and point out anything in it that could be construed as a criticism of anybody. It just gets silly, trying to have a normal conversation by written word, sometimes! Thomas ends his post with: "What happened to 'relax, don't worry, have.......'?" Shouldn't that be: 'Relax, Don't Worry, Have an All Grain?' (for those who can't read between the lines, here's an explicit <G> for you.) Enjoy the brew! Michael Gerholdt Return to table of contents
