---------------------------------------------------------------------- Date: Thu, 7 Aug 1997 06:48:17 -0700 From: dwhitwell at foxcomm.net (David Whitwell) Subject: Controlling Fermentation Temps O Great Brewing Collective: I've seen the recent discussion of temperature controllers both here and on RCB, and I finally decided to chime in with something I found on the web. At http://hbd.org/users/mtippin/ (sound familiar?) is Marty's Homebrew Gadgets Page (man, this guy is my kinda gadget junkie), and near the bottom is a link to http://members.aol.com/kennyeddy/chiller/chiller.html which has plans for building your own fermentation chiller, using polystyrene and frozen plastic milk jugs. The author says his unit can be built for ~$70 if you use all new parts. I modified it to be a bit sturdier, but the cost was well under $50 because I scrounged stuff. Why? Because that leaves my spare fridge open to store homebrew, my frozen hops, and uses a heck of a lot less power than a fridge temp controller would. Brew On!

Date: Thu, 7 Aug 1997 09:50:41 -0400 From: "David R. Burley" <Dave_Burley at compuserve.com> Subject: Hop Back,Arty Acronymn Brewsters: Compuserve lied. I still have the same transmission problem. Sorry about this inconvenience. - ---------------------------------------------- Braam Greyling asks for information on a hop back construction. I know what I mean by hop back, but I'm not sure I know what you mean, since these pages and publications have used the term to be some sort of inline filter into which you can also dry hop! while racking the wort.. In the British brewing industry the hop back is most often a shallow tank with a bottom filled with narrow slots which can be covered by a = sliding plate also with slots. The hot boiled wort is pumped to the hop back with the plates in the "closed' position and allowed to settle. The plate is slid to "open" and the wort is then filtered through the hop bed to remove the hot break and the hops simultaneously. This wort is then directed to the cooler and aerated before fermentation. = I basically do the same thing when I rack my hot, whirlpooled wort through a "Choreboy" an unsoaped copper or SS metal turnings kitchen scrubber pad ( see back issues for more discussion) at the bottom of my racking cane leading from my wort boiler to my Cc cooler setup. This performs amazingly well, with no clogs and when the transfer is complete the whole leaf hops I use are wet, but there is no liquid left. The hot break is trapped by the hops just as in the commercial variety. Cheap, simple = and works better than anything else I ever tried ( and that's a lot of things). - ---------------------------------------------- = Privately accosted by the acronym police again, I reply RT is " room temperature". In STP terms ( I.e. Standard Temperature and Pressure) it is 20C ( 68F). In Britain of course that would be 62F (16C) ( as I recall my chilly Welsh Post-doctoral days) and in most of the US 68F = or in my Grandma's house 85F (30C)! - --------------------------------------------- Keep on brewin' Dave Burley Kinnelon, NJ 07405 103164.3202 at compuserve.com Dave_Burley at compuserve.com = Voice e-mail OK = Return to table of contents

The event includes a homebrew competition as well as a single malt scotch tasting and a cask conditioned ale tasting both conducted by Michael Jackson. See http://reality.sgi.com/piatz_craypark/brewfest.html for complete details of the events. The online stuff doesn't have the entry form and the bottle labels (yet), you can the standard AHA sanctioned competition forms (I would like to just be able to link to the AHA's server rather than generating my own forms). If you can't read WEB pages send me an email and I can snail mail a copy to you. The competition has most of the standard styles placed in 14 categories. The prizes are great; $100 for each first place, $50 for second and $25 for third, each is in addition to a very nice medal. This year the Minnesota Brewfest is one of the competitions participating in the Midwest Homebrewer of the Year Award. Entries are accepted between 11:00 am on Monday September 22nd and 6:00 pm on Sunday September 28th. If you are interested in judging the competition please let me know. We anticipate judging both the weekend of the event and the weekend prior to the event. - -- Steve Piatz Cray Research, a Silicon Graphics Company piatz at cray.com 655F Lone Oak Drive 612-683-5268 Eagan, MN 55121 Return to table of contents
Date: Thu, 07 Aug 1997 10:00:49 -0400 From: Spencer W Thomas <spencer at engin.umich.edu> Subject: Carbonation & fill level, an experiment Bottom line: Unfortunately, the result of the experiment is that we need to do it again, because of problems in learning to use the equipment. (We should have started with some Budmilloors, instead.) Participants: Spencer Thomas (instigator), Stephen Klump (brewer), Jeff Knaggs (owner of test equipment). Stephen bottled 2 bottles each of a batch of pale ale with a high fill, regular fill, and low fill. High fill was to the rim, regular about 1 inch down, and low to the shoulder of the bottle. The bottles were allowed to condition naturally for about 4 weeks. Spencer then drove them to the Quay Street Brewing Co. in Port Huron, where Jeff Knaggs has a Zahm-Nagel carbonation tester. We used a jury rig to fill the tester from the bottles. This rig was, we think, the main cause of our problems, as it leaked quite a bit. We ended up needing to use both (12 oz) bottles of each sample for each test, so we could only make 3 measurements. The results were totally inconclusive, as the "measured" carbonation increased in the order of testing: regular, low, high. Jeff has figured out a new rig using stainless-steel tubing instead of vinyl, which he thinks will work much better next time. Now it's just a matter of getting some 22oz bottles filled and conditioned for testing. =Spencer Thomas in Ann Arbor, MI (spencer at umich.edu) Return to table of contents

Actually, 10 psi is my optimum low pressure. Two questions: 1) What is the best configuration of the regulator and flow meter? Should the regulator be between the flow meter and the tank, or between the flow meter and the burner (providing back pressure)? Observation: With the regulator between the flow meter and the tank, the flame at the burner appears to be larger. 2) Is pressure drop in the line a major factor? Will a 20 foot line behave the same (in terms of flame size and BTU output) as a 50 foot line for the same regulator/flow meter configuration? OK, technically three questions, but the last two are pretty much paraphrases of each other. I'll drink a Coors product as penance.

Date: Thu, 7 Aug 1997 11:27:51 -0400 From: bourdouj at ERE.UMontreal.CA (Jacques Bourdouxhe) Subject: Re: Foreign Stout ( serious answer ) Hi Brauwmeisters, Dave Draper ( in Dallas ) wants to know the characteristics unique to Foreign Stout. According to Graham WHeeler's book " Brew classic European beers at home " Guinness Foreign Extra Stout ( FES ) has the following specifications: O.G. 1.073 Alcohol content: 7.2% by volume Bitterness 65 EBU Color 200 EBC " A world classic,its roots in the early porters and stouts of London and Dublin. The beer is a blend of regular stout and a second beer that is matured in oak vessels. It has the horse-blanket aroma that is a result of attack from wild Brettanomyces yeast... " So, it seems that a FES should be: strong, hoppy and ... include a wild yeast. Conclusions: If you want to brew a FES true to style, you'd better subscribe to the Lambic Digest or maybe blend it with some Rodenbach Grand-Cru . I think FES is a unique and VIABLE style and should not be killed by Dave. I hope this helps. Now, I have 2 questions: 1) Why is it called " Foreign "? is it because it is or was brewed only for export and is not available in Ireland, like IPA was brewed for export to India? 2) Where can I buy Guinness FES in Canada?

Date: Thu, 7 Aug 1997 08:28:28 -0700 (PDT) From: Steve Jackson <stevejackson at rocketmail.com> Subject: Budweiser's born-on bull I know this isn't really homebrew related, but I figured the collective would find this amusing. There was a small item in the alternative weekly here in Indianapolis this week about a guy drinking a Budweiser that was "born on" July 10, the exact same day he was drinking the beer. Bud's local distributor attempted to write it off by saying that A-B's Columbus plant, where Indy's Bud is produced, is brewing 24-7, so it's possible that an early morning truck heading out of Columbus on the 10th made it to Indy, and the distributor got the beer to the bar and the bar got the beer into the customer's hands all on the same day. Notwithstanding the fact that I've never seen a distributor move beer that quickly, something seems more than a little fishy about Bud's "born on" dates here. Even for as something as thin as Bud produced by heavily industrial mechanisms, there's no way in hell that a fermentation could be completed in a day. And I would guess Bud's "exclusive beechwood aging" takes a bit longer than a few hours as well. Just goes to show what a multi-million-dollar marketing budget can do. _____________________________________________________________________ Sent by RocketMail.

Date: Thu, 7 Aug 1997 13:08:17 -0400 From: "Ted Major"<tmajor at exrhub.exr.com> Subject: Re: Cold Box In today's HBD, Dave Burley suggests a cold box for Jim Graham, who doesn't have room for a beer refrigerator. It just so happens that I built a prototype this weekend. I'll put up a more detailed account on a web page with photos after I refine it a bit, but here is the rough-and-ready version. I picked up 50 feet of .25" ID soft copper tubing at the local building supply warehouse, along with a few extra hose clamps. I used a keg to make a neat coil that fits into a Styrofoam cooler (until I get a nicer one for the task). I put it in-line between the liquid out and picnic tap and filled the cooler with ice and water (the icemaker in the refrigerator didn't make enough ice to fill the cooler). On the whole, it worked well enough, cooling the beer from 65F to about 45F. It took about 35 PSI of CO2 to move the beer trough the coil, but room temp beer needs more pressure to maintain carbonation. It leaked a little bit where the beer line met the copper tubing, but I think I can take care of that. I think a full bag of ice would also cool more efficiently than the insufficient amount of ice I used for the test. Ted Major Athens, Georgia Return to table of contents

Date: Thu, 7 Aug 1997 14:57:29 -0400 (EDT) From: th22 at cornell.edu Subject: Hop disease diag A few days ago someone (sorry, I deleted your post) inquired as to possible reasons for yellowing of the lower leaves of their hop plants. David Burley suggested that it could be caused by Verticillium wilt, which Dave attributed to a virus, and further said that the symptoms on his tomato plants disappeared after switching to a VFN variety. Ooh! Ooh! Here's my chance to contribute! I'm a pseudo plant pathologist (I study plant-pathogen interactions at the molecular level) but I've had enough traditional plant path to know that Verticillium is in fact a fungus, not a virus. The symptoms on tomato are mild wilting which is most pronounced during the hot part of the day. Plants generally recover late in the day and look fine in the morning. Advanced symptoms include marginal and interveinal necrosis of the (typically lower) leaves which often has a v-shape with the wide end at the leaf margin. If you pull an infected plant and cut away the epidermal tissue, the vascular tissue will be brown, and fungal hyphae will be visible under a dissecting microscope or possibly with a good hand lens. On HOPS (aha, some brewing info!) the leaves generally don't droop as they do on tomato, but the leaves do wither while remaining fairly rigid. Upper leaves will wither if the plant is severely infected. If a bine is pulled, the crown will remain attached to the stem (unlike a Fusarium-infected bine) and the vascular tissue will be brown. This browning is a key diagnostic symptom, as many problems can cause wilts. In both tomato and hops, leaves will have grayish patches of sporulating fungi on them late in the season. Verticillium wilt typically occurs in wet or poorly drained soils, and is worst on Fuggles. I checked our Crop Protection Chemical Control manuals for some labeled chemicals for use on hops. The only labeled chemicals are all pre-plant soil fumigants. They include Telone II and C-17, and Vapam, and can only be applied by Certified Applicators. On tomato, Benomyl and carbendazim fungicides can be used as soil drenches. I'd suggest pulling some of your diseased plants immidiately after harvest and checking them for the characteristic brown vasculature. You could also check the roots for nematodes. If your plants are in poor soil nitrogen fertilizer may help, but the affected leaves won't recover their former green glow. Good luck!! Tom Herlache th22 at cornell.edu Return to table of contents
Date: Thu, 7 Aug 1997 13:25:18 -0700 (PDT) From: homebrew at dcn.davis.ca.us (Sean Mick) Subject: Celis White clone Barry, I liked what you had to say on the HBD today. I also thought it was inappropriate for people to chime in that Blue Moon was a hack and not to "style" (whatever that means for a category that only has a few commercial examples!), and then not even address the question/request for a clone. I recently brewed a Belgian White that was meant to be somewhere in the neighborhood of either Celis White or Hoegaarden Witbier. You may also want to check out the Cat's Meow for a recipe called Zoso White, which I think is supposed to be similar. Pierre Celis uses Cascade & Willamette for hopping, and Coriander & Curacao Orange Peel for aroma. Raw Texas Winter Wheat makes up roughly 50% of the grist, with the rest being domestic pale malt (I would guess Briess or Great Western). The yeast is most likely from Hoegaarden, but some have commented (Michael Jackson included) that the yeast profile is somewhat softer than that of Hoegaarden. Since you want an extract recipe, I would suggest finding a domestic wheat extract (50/50 or thereabouts), using roughly 7 lbs. for 5 gallons, and then use enough of the Cascade and Willamette to bitter at ~20 IBUs. There should be no hop aroma, some hop flavor, though. Use 1 oz. Orange peel and 1/2 oz. Coriander for the final 5 minutes. Buy Wyeast # 3944 Witbier yeast, White Labs Wit yeast (from San Diego, ready to pitch), or similar yeast from a competitor (or culture it from Hoegaarden bottle). Ferment at ~66F until done, should reach a FG of about 1.006-1.010 (depending on fermentability of extract). My all-grain recipe reached 1.006. Here's what I did, for reference: 4.5# Belgian Pils malt 3# White wheat 1# Flaked wheat 1/2# Flaked Oats 1 oz. Domestic Kent Goldings-60 min 1/2 oz. Czech Saaz -20 min 1/2 oz. Orange Peel-5 min 3/4 oz. Coriander-5 min 1/2 oz. Orange Peel - dry herb in secondary 1 coriander seed whole in each bottle (per Charlie Papazian's suggestion) White Labs Wit yeast (from Hoegaarden) 10 ml Lactic Acid at bottling (actually, I used almost 1/4 of a 2 oz. 88% sol'n bottle) OG~1.050, FG 1.006 IBU~ 20 Mashed in at 135, raised to 150F for 1 hour. Boiled 1 hour with above hopping schedule, full 6.5 gallon boil (reduced to 5 over hour). If I had it to do over, I'd add all of the Orange Peel at the boiling, like indicated above. My beer has a pronounced coriander presence, so I would guess I have Charlie P to thank for that. Otherwise it is effervescent, tart, and refreshing. Color is right on for "style." Don't forget to pulverize the Orange Peel and coriander, like in a coffee grinder. Also, you should add Lactic Acid at bottling time, 5-10 ml should do nicely. You are shooting for 3.6-4.0 pH. Good luck! Let me know how it turns out. Sean Mick Mick's Homebrew Supplies http://www.dcn.davis.ca.us/~homebrew Return to table of contents

Don't know fermentability %, but it should be more fermentable than most malt extracts, since it is meant to lighten beer's flavor and body.

Is this a >widespread view? >Graham L. Barron responded: >I've always found DWC to be of the highest quality and regularly of high >quality, at that. DWC seemed always to make the best Belgians and German >lagers. I'd have to agree with Graham. I sell almost the complete line of DWC malts and have not been let down yet. I use them regularly in my own brewing. I have noticed that Special B can have quite a range of colors from year to year, which will affect the roasty character a bit. Personally, their Munich malt is my favorite, but all the others are quite nice. I would recommend them to anyone, especially over some of the domestic malt when being considered for a Belgian or German brew. I have not tried most of the German malts due to difficulty in consistently obtaining them, however. I may change my mind on some recommendations once I get ahold of some Weyermann malt. Storage, and dealing with a reputable wholesaler could explain some of your shop owner's difficulties. I buy from West coast distributors in 50lb. sacks, so I know that I am getting genuine DWC (made exclusively for Schreier). I sincerely hope your shop finds a way to keep the line of malts available for you. Sean Mick Return to table of contents
Date: Thu, 7 Aug 1997 17:02:52 -0400 (EDT) From: Alpinessj at aol.com Subject: 5l mini kegs - Jim Graham I have not seen an answer to any of Jim's questions over the last couple of days so I'll give my input. I started using the 5l mini's because I did not want to get into the 5 gallon corny's and C02 dispensing system (actually, my wife would not let me). But w/ 1 keg and 22 oz bottles each batch did not take a lot of time to bottle. I basically treated the 5l mini as a big bottle as far as priming goes. However, since there is less head space per given volume of beer, you have to cut back on the amount of priming solution. I found that half strength of a normal bottling priming solution worked well. I would pour half my priming solution in the bottling bucket, then rack the beer in, fill the 5l mini, pour the rest of the priming solution in, gently stir, then finish bottling as normal. Buying the 5l mini's with beer already in them works fine, but you can't follow the instructions or use the taps that come with them. They tell you to dispense the beer by turning the keg upside down (using gravity to push out the beer) and cut a hole in the top to prevent a vacuum. If you dispense them with the taps meant for homebrew and the C02 cartridges you'll be fine. Lastly, a word on the Carbonator. I have never used this to carbonate the 5l mini's, but I found it very usefull in dispensing the beer when you get tired of buying the C02 cartridges. If you use a grolsh-type washer to make a good seal, you can screw it into the back of the tap instead of the C02 cartridge attachment and then hook it up to a ball-lock C02 dispenser. This provides for a smoother pour because you can regulate the C02 much better, and it is actually cheaper than buying the cartridges in the long run(I can fill my 10 lb cylinder for $11 and it lasts 6 to 12 months). The cartridges are still good if you go on a camping trip or hiking where you don't want to lug around a big C02 cannister. Anyway, hope this helps and I'm sorry this went so long.

Try two 45-deg couplers >to drop from the hole to the floor level. In my set-up,I raised the copper manifold using short pieces of 1/2" copper tubing screwed to the bottom of the manifold.This gives a space for draff to collect under the manifold and IMHO results in a clearer runoff. Mine takes a thick wall 3/8" vinyl tube through the bung to a 3/8 X 1/2 coupler on the manifold. I got the idea from a fellow club member who has his manifold sitting on a bed of 1/2" marbles.

Date: Thu, 7 Aug 1997 16:38:06 -0400 From: "Moyer, Douglas E (MIS, SalemVA)" Subject: Flaked barley & DME All, I spent some (company) time perusing the HBD archives on using flaked barley in an extract stout. The primary opinions are as follows: 1) Go ahead & steep for 30 min. at 150 deg. 2) Steep with the extract at 155-158 deg for 15-30 min, only if the extract is diastatic. 3) Do not steep--will not provide head retention & will cause haze (not visible in a stout). Partial mash with equal amounts of pale malt at 155 deg for 1 hour. I am using Munton's amber dry malt extract, which my homebrew supply owner *thinks* has very little diastatic power. Based on the experience of those of you that are extract-brewing, how should I use the flaked barley (1 lb for 5 gallons)? I am not going to build a mash tun at this time. Will I get any head retention if I steep? (I really don't care about the haze, since I will be using 1 lb of roasted black barley.) I am willing to try to do a partial mash using a crock pot (to hold heat) and a strainer if I need to do so. If I need to do a partial mash, is equal parts of pale malt the way to go? I am planning on brewing on Sunday, so I would like to get a private email response by this afternoon (Friday). I will summarize to the group if I get anything worth summarizing. ;-) Doug Moyer Big Lick Brewing Collective "Big Lick--looking for better head." Return to table of contents

Also as time goes on, it loses body and head retention. Dave B suggests it may be an infection. Last week I spent 4 hours cleaning the brewery, basement and refrigerator because it was beginning to smell musty/mildewey. It's spick and span now and also sanitized becuase I wiped everything down with a bleach solution after washing. I even took apart all the taps in the fridge, sanitized those and cleaned all the hoses too. Worked up a good sweat. If the problem was sanitation, it ain't no more.

The Hop Research Department holds *the* elite stocks of all hops grown in Britain. Material derived from these stocks is supplied to specialist propagation firms, then to the growing industry. Hop varieties bred at Wye have formed the basis of most of the hop breeding programmes throughout the world. It has been the main centre for scientific research on hops in Britain for over 100 years and has become established as a world leader in most aspects of hop research. The article was published in the Journal of the Institute of Brewing. This is one of the most highly regarded technical publications on brewing in existence, and all articles are rigorously screened by experts from the industry before going to print. Colin Green's statements would have arisen from months of extensive research at Wye beforehand. So before dismissing these claims out of hand, just ask yourself, "Do I know as much about hop breeding as Colin Green would?" If the answer is yes, you're probably in the wrong job. Andy.

They were clearing out some camping equipment, including a two- burner propane stove w/stand, for $79. Now that is a fair price, but the interesting thing I noticed was this Cache Cooker unit has two ring-style burners identical in appearance to the Superb units. Each burner is rated for 30K BTU. Carpe burners!! If I didn't already have two pseudo-ring high-pressure burners, I'd have bought this. Its a good deal. The stand they're in are probably OK for 5g batches, but the burners themselves are easily removed for custom mounting. Galyan's also is selling the high pressure pseudo-ring single burners for $29.

Because I'm brewing several batches in short order, I bought a 15 kilogram vat of malt extract. Here's the question: how do I measure out the appropriate number of POUNDS of extract without a scale? Does anyone have a good approximation for how many cups of extract equal a pound? I've consulted all the homebrew books I have access to as well as the Joy of Cooking.

Date: Fri, 8 Aug 1997 08:52:15 -0500 From: ajdel at NOSPAMmindspring.com (A. J. deLange) Subject: Low Water pH Rick Pauley asked what could be done about water at pH 5. I would guess that this water comes from a well in which case it is quite possible that the pH can be raised to a reasonable value simply by letting dissolved CO2 escape. Try pouring a couple of quarts back and forth between buckets a few times and see if the pH increases. If it does, keep going to see how high the pH can be raised by this process. You might be surprised. If this is sucessful then, obviously, aeration will do the trick. Boiling will also remove CO2 and raise pH but may also precipitate chalk lowering calcium ion concentration (usually bad) and simultaneously lowering alkalinity (usually good). If aeration does not raise the pH then have the water checked. There really isn't anything I can think of which should find it's way into the water naturally other than CO2 which would lower pH this much (I don't consider sulfuric or nitiric acid from acid rain "natural").

Date: Fri, 08 Aug 1997 09:12:15 From: Jay Reeves <jay at or.com> Subject: Re: yellowing hop leaves There was some talk a few weeks ago about the leaves yellowing on home-grown hops. Someone (sorry, forgot who) I think mentioned that it was a chemical deficiency and that putting some magnesium sulfate on the mounds would correct the problem (or at least it did for them). I did just that to my plants and yellowing has occured since then to leaves that were green at the time of the MgSO4 application. My wife and I happened to be out in Yakima, Washington last week and toured HopUnion and Roy Farms. Everyone knows that HopUnion is a hop broker/processor. Roy Farms is one of the largest hop growers in the Yakima Valley (not to mention they are also one of the larger fruit producers of the area -- yes, fruit alongside hops). We talked with Leslie Roy (one of three brothers that have been at hop growing all their life) and I asked about yellowing leaves. It's strange, because he finished my question before I could -- obviously it was a problem he was all too aware of. He said the yellowing older leaves were a result of either irregularities in the watering patterns, or not enough sun. Leslie said that if the plant experiences periods of dry along with periods of wet, the older, lower leaves will turn yellow and drop (he didn't explain why that is - can anyone here?). He recommended that the best solution to this was to ensure that the plants receive water on a daily basis, but warned not to overwater. He said that a drip-irrigation system was ideal for this and easy to do, even for the hobby-grower. Leslie also said that shade (or not enough sun) will cause the older, lower leaves to yellow in the same way. His explanation was that the plant senses a decrease in sunlight and "thinks" it does not need the leaves for photosynthesis, so it drops them. He said yellowing from that doesn't physically hurt the plant, although yellowing from watering irregularities could. I mentioned the deal about adding magnesium-sulfate and he said that if the yellowing was due to a chemical imbalance in the soil, the entire plant would be affected, not just the lower, older leaves. I wonder if by applying the MgSO4 by the person that posted about it, that you didn't just happen to water them a little more thinking that it would get the MgSO4 into the ground better, and thus it was actually the extra water that did the trick and not the MgSO4? Just speculation.... The drip-irrigation systems I observed in place in the fields were of a hard, black plastic, 1/2"-3/4" diameter hose (technical name?) with small holes punched in it every few feet. Water was run through these continuosly, providing water to the plants. This type of system would be easy to make. I believe this type of hose may be used in plumbing. The other irrigation system I saw in fields had a small ditch between the rows, constantly being fed water from a shut-off valve at the end of each row. Leslie said that the ground around it only needs to be kept moist, not saturated with water. Another thing he said was not to fertilize after the burrs start to develop because the plant would go into a growth mode and quit putting its energy into hop development. In the "big-boys" hop fields, the fertilizer is injected into the water. If anyone ever finds themselves in Yakima, you owe it to yourself to call ahead and arrange a tour at each of these places, but please call ahead. They are very nice people and are willing to talk all day about hops, just as brewers are willing to talk all day about beer. I wouldn't recommend going when they are processing the hops because they may be too busy. We were shown the entire process that the hops go through from the field to the bail at Roy Farms, and the processing that HopUnion does in pelletizing and packaging. BTW, they're going to start picking the hops in 2-3 weeks and will continue into October. The Tett's are in full swing and will be the first to go, with everything else right behind them. -Jay Reeves Huntsville, Alabama NOTE: Any replies need to manually change the "or" in the "reply to" field to "ro" - sorry, but blame the spamers for that!

Williams Brewing (www.williamsbrewing.com) seems pretty good - great prices, nice web site where you can track your order, etc. - but I'm worried about buying LME from them. They sell in pre-packaged 6# bags. I usually buy from other places that have big drums of LME that I can get say, 7.3# in a bucket. Is the inability to get the exact amount a big problem when brewing? Do you make up the difference between 6# and 7.3# with DME? How/where do you store extra LME (like if you bought 12# from Williams and used 7.3#)? Does it go bad? Thanks, Bret - -- A nuclear war can ruin your whole day. Return to table of contents
