I was specifically referring to statements people have made suggesting that Wyeast is doing something illegal or unethical. While I certainly did publicly question the quality of of some specific products, I never stated or implied that these mill manufacturers might be doing something unethical or illegal and that's an important distinction. I think it's acceptable to state that you have a problem with a product or that you're dissatisfied with certain products. In fact, I would encourage this as it contributes to the discussion. However, if one suggests that a certain manufacturer is doing something illegal or unethical, you'd better have some damn good evidence to support your claim if you don't want to be sued for libel. In any case, it's your choice; I'm not a censor. To clarify, I never meant to imply that people should keep their complaints to themselves, just that they might want to consider the potential repercussions of certain insinuations. FWIW, there was a case a couple of years ago where someone was successfully sued to the tune of $40,000 for libelous statements posted to usenet (don't say I didn't warn you). Just think before you type! >I don't recall anyone saying Wyeast was knowingly selling bad 1056 yeast. I was specifically referring to the following: Harlan <blacksab at siu.edu> said: >>>be reminded that Wyeast was caught selling Brettanomyces yeast (that's how >>>the package was labeled) when in fact the package contained mostly Ale This implies that they were "caught" deliberately doing something "wrong". It's hearsay, unsubstantiated, and potentially libelous. >>>So don't expect Wyeast to be forthcoming about any real or percieved >>>problems with their products. This implies that they intentionally sell "defective" merchandise. I hope that clears the air. If you still don't get my point, email me.

I tape the gas-out line from the tank to the blow stem on the orange cap (my gas out line would not fit the tap, otherwise.) NEVER TAPE THE CAP TO THE CARBOY. There is no need to do so, in any case, since the seal should be quite good without tape. >From the original post: ========================= After filling the secondary carboy with CO2 to purge any air present, I attached the gas out line from my tank to the second hole (the one used to blow into for starting a siphon) on the carboy cap.

Date: Fri, 10 Nov 1995 14:25:33 -0500 From: Robert Waterfall <waterr at rpi.edu> Subject: Re: Chlorine Several people have commented on the chlorine bleach and dioxins connection. Here's my two cents. First, I'm an environmental engineer, but water pollution by organochlorines is not my specialty. That said, what I've heard (pretty much second-hand and half-remembered) about chlorine bleach and dioxins is a problem that occurs when bleaching paper so it's nice and white. In that process, you have high concentrations of hypochlorites and of organics of the general shape needed to form dioxin molecules. This can lead to the formation of very small quantities of chlorinated dioxins, but (some think) it only takes a little. The problems occur with paper plant effluents (which can be plenty nasty even without dioxins) and if you ingest the paper or leach the dioxins out of it somehow. You might have noticed all the unbleached paper coffee filters available. They hit the market shortly after the bleach/dioxin hit the news (in a minor way) a few years back. Why didn't the mainsteam media make a fuss? Choose your favorite conspiracy theory. Or perhaps the first reports were exaggerated or misunderstood. Oh yeah, beer! I wouldn't worry about this in terms of beer-making at any level of production. Massive doses of chlorine may however kill the bugs in your septic system. Since we haven't seen any posts about that, I guess homebrewing doesn't generate enough of a load to cause any problems. Of course I wouldn't expect it to since I use more bleach in a load of laundry than for a batch of homebrew. Bob Waterfall, Troy, NY, USA Return to table of contents

Can you elucidate us? Well, you're both kind of right. As far as I know, chlorine in water doesn't react to form dioxins (of which I think there are 75 types). Chlorine and bromine, which are common disinfectants used in drinking water, do react with organic material to form chloroamines, chlorides, and trihalomethanes (THM) which include chloroform, bromoform, bromodichloromethane, and dibromochloromethane. THM in drinking water _is_ regulated by USEPA, with the maximum allowable level set at 100 micrograms per liter. The reason this is allowed is that the health risk caused by _not_ disinfecting is astronomical, and other technologies (such as ozonation) are considered too expensive. How much _can_ people pay for water? Now back to your regularly scheduled beer-gramming. Regards, Michael Higuchi Geologist, Engineer, and Groundwater Cleaner-upper Return to table of contents
Date: Fri, 10 Nov 1995 12:09:34 -0800 (PST) From: Dave Riedel <RIEDEL at ios.bc.ca> Subject: Partial-mash strainer hole size/Cooler question A number of digests ago, I questioned Dave Miller's recommendation of drilling hundreds of 3/16th inch holes in a plastic bucket to make a partial-mash strainer. The responses I received generally agreed that 3/16ths seemed too big- one brewer had already tried this set-up and it clogged up on him. Two people suggested that I use a grain bag. So, armed with a grain bag, I tried a partial mash stout last weekend. In general, all went well. However, "Miller's-hole's" made for one heck of a fast sparge. There was absolutely *no way* I could 'add liquid to cover the grains and add more as the level drops below the surface of the grain bed', (unless I poured in about a gallon at a time). My SG ended up 3 points below Miller's predicted value. Is the low SG likely the result of the very short sparge time? This is my first attempt at mashing/sparging, previously I was using extracts and steeped specialty grains, so feel free to correct me if I've got something wrong here. *Comment: In any case, I think perhaps Miller's 3/16ths hole size in "Brewing the World's Great Beers" may be a typo. I don't recommend it. It seems to me that a smaller hole size would 1) eliminate the use of a grain bag and 2) enable a slower sparge rate. Am I wrong? *Question: This mashing stuff is great fun.... I haven't even tasted the beer yet and I'm already hooked. With one eye on the future, I'd like to get a 10 gal cooler to mash/sparge in. Is it possible to sparge a partial-mash amount of grains (about 4 pounds) in one of these big coolers? Or will the bed be spread too thinly?

Has anyone been successful at modifying it for better performance? If so, what did you do? Thanks. Yeah, the Hg bath is great, but heating it is a PITA. I had to use my dihydrogen monoxide generator in series with several indoor propane stoves to turbocharge the heat exchange. I like to fire it all up in the basement before I go to bed, then I can cool in after breakfast. Don't forget to lock all your doors and windows before you turn in! I use the excess heat to melt down the guts of car batteries. The metal you can get out makes funky soft sculptures. I like to make beer steins out of it, it's so soft and workable. - Rob Return to table of contents

Aqua-Check 5-in-1 test strips are manufactured by Environmental Test Systems. Their phone is 800-452-0206, ext. #12. The distributor I bought them from is called Mid-City Supply (219-294-5551); ask for the inside sales dep't. If you call the manufacturer they'll refer you to a local distributor. Unless you're on the left coast, Mid-City is probably your best bet; no minimum order and they take plastic. These strips test for free chlorine, total chlorine, hardness, total alkalinity, and pH. These aren't the best pH strips though. I recommend ColorpHast test strips for monitoring pH. They make some with a narrow pH range that's ideal for brewing. I get mine right here in the lab, so I'm not sure where you can buy them, but most of the major scientific suppliers stock them (or a similar product). I think a few homebrew suppliers have them now too. Good luck. Tracy in Vermont aquilla at salus.med.uvm.edu Return to table of contents

Date: Fri, 10 Nov 1995 15:55:01 -0600 From: David.Muzidal at dssc.slg.eds.com (David M. Muzidal) Subject: Brewing water and Brita filters My local water treatment plant treats the water with chloramines, which supposedly cannot be boiled out of solution like free chlorine can (discussed in the Zymurgy '95 "Great Grains" issue). So I bought a Brita filter since it has a carbon filter and eliminates up to 90% of the chlorine. The filter also reduces lead, copper, odors, particulates and softens the water without adding sodium. This all seems desirable. However, the last point may be causing me some trouble. The pH of the water out of my tap is 8.0. After filtering it through the Brita, the pH is ~5.2! Here are my local (Plano, TX) water stats: (all numbers are mg/L, which is the same as ppm) Calcium (Ca) 30 Magnesium (Mg) 3 Sodium (Na) 9 Bicarbonates (HCO3) 92 Carbonates (CO3) 0 Sulfate (SO4) 27 Chloride (Cl) 12 Total Alkalinity 75 Noncarbonate Hardness 19 Total Hardness 94 Chlorine residue 2.8 pH 8.0 What I *think* has happend is that in reducing the temporary hardness of the water, all of the bicarbonates were removed allowing the calcium to pull down the pH. Is this correct? If so, adding up to 1 tsp. of calcium carbonate to correct the pH *should* be OK. My last partial mash with 2lbs of Briess two-row, 2lbs DW-C Caramunich and boiled Brita water resulted in a mash pH of ~4.9. Stouts and porters may require too much calcium carbonate to raise the pH into the correct range. Are there any chemically literate folks out there who can provide any explanations or suggestions regarding this? How should I treat this water? Keep using the Brita (it does have some advantages) and add calcium carbonate, or should I just use a plain carbon filter and boil the water? Inquiring minds want to know! - Thanks.

Date: Fri, 10 Nov 1995 14:20:00 -0500 From: HAROLD.SILVERMAN at BAIN.sprint.com Subject: Sam Adams Bashing & Blue Fin I must say that I am a little disturbed about the recent Sam Adams bashing which has been going on. I may be biased, as I am from Boston, but while I have little knowledge of S/A's business practices (except that they are indeed a contract brewer), I think that they (and Pete's to name another) should be given some credit. I believe that S/A has contributed greatly to a rise in the level of the tastebuds of mainstream America. So while the majority are still swilling Bud and worse, many of their companions are indulging their taste buds with some flavor. I am not contending that the brewers at Sam Adams are brewing the finest craft beer in America. I personnaly tend to prefer many beers brewed by Harpoon brewery (again I'm showing my bias towards Boston beers), but it is nice that in just about every bar or restaurant I can at least get a nice Sammy. I am especially bothered by those who have implicitly or explictly lumped S/A and Pete's with the Big Three. When was the last time that A/B or any of their oversized brethren were willing to mass produce any of the following: a wheat (not to mention a Cherry Wheat), a bock, a stout, a porter, or a fruit beer. All of which the Boston Brewing Company does regularly. On another note, I have a question. I am especially fond of Stouts. Until last May I went to school in Brunswick, ME (Bowdoin). While there I occasionaly indulged in Shipyard Blue Fin Stout and absolutely love it. I even think it was even better than the Guiness I drank in Galway, Ireland. I am wondering from any of you who are lucky enough to know anything about it, what makes its distinctive flavor? And where can I get it down here in the Boston Area? Personal E-Mail if people think it isn't important enough for the digest.

Date: Thu, 9 Nov 95 14:21:55 CST From: korz at pubs.ih.att.com (Algis R Korzonas) Subject: Chapeau Lambic [sic]/Home Brew Technique.../Yeast complaints Ron writes: >Last night I had a truley unique beer, Chapeau Mirabelle Lambic, a true >Belgian lambic flavored with plum juice. Sorry, it's not a true Belgian lambiek/lambic... it is a beverage (I wouldn't even call it a beer) wich has a few percent lambiek/lambic (which is a spontaneously-fermented, very sour wheat beer) added to what is otherwise a regular ale and a great deal of fruit syrup. Why add the lambiek/lambic at all? So you can put the (now chic) name on the label. Belgian law says that anything labeled "Lambiek" or "Lambic" or "Lambik" must contain some beer that has been spontaneously fermented. >It had a very sweet taste like >the fruit juice had just been added and none of the sugars had >fermented out. Every fruit beer I have had including Kriek and >Framboise have had fruit flavor but none of the sweetness. My question >is how do they do this? The only thing I can think of is to filter out >the yeast, add the juice, keg it and force-carbonate it using a CP >filler to bottle with. Am I on the right track? You've got it right, but to make something that tastes like those syrupy sweet Chapeau beverages, you need to use syrup, not juice. At the risk of sounding like a jerk, I ask: why bother? If you really want fruity drinks, just get some fruit syrup, add a little water and vodka, force carbonate and then CP bottle. In my opinion, it is far too much work and takes too much time (2 to 3 years) to make a plambiek (pureculture lambiek) only to cover up all its flavour and unique aromas with fruit syrup. If you are going to go through the expense of getting the proper microbiota and go through the long, time-consuming effort to make a plambiek, shoot for a pgeuze/pgueuze and if that doesn't turn out quite right, then add real cherries, real raspberries or real plums and make pkriek, pframboise or pmirabelle. *** Michael writes: >Throughout my short career, I have NEVER taken a >temperature, specific gravity reading or virtually any other measurement >imaginable.

My question is >then, "Why bother with all those measurements, if they aren't absolutely >necessary?" Any comments???? You can make perfectly good beer without taking any measurements -- heck, you could even make perfectly great beer without even weighing ingredients! Personally, I do both take measurements and weight ingredients, but that's mostly because if I hit upon a spectacular beer, I want to be able to reproduce it. The only measurements I feel are important in extract brewing are the temperature in which you rehydrate dry yeast (90-110F or so) and the temp of the wort into which you pitch yeast. You can simply guess and still make good beer, however. For years, I didn't even have a scale -- I would just buy 2 ounces of hops and if I needed 1.75, I would simply use 7/8 of the package. When it comes to all-grain or partial mashing batches, temperature gets a little more important. If you overshoot your saccharification temperature you can denature (ruin) your enzymes and the resulting liquid will not be beer, but rather a mixture of starch and water -- a sort of runny wallpaper paste. *** Tracy writes (quoting Eric): >>It would be >>difficult for any single brewer to state unequivocally that a problem is due >>to the yeast producer and not to their own bad sanitation or recipe. Only > >Absolutely true, especially depending on at which point the "problem" is >detected. That's part of the reason one should take it up with the supplier >before posting public complaints. This may be true in the case of a package of yeast that is suspected of being infected, but that is not the case here. At issue is a product that for two years now has been labeled as "Brettanomyces Bruxellensis" and was found by a homebrewer to have contained mostly Saccharomyces and a small amount of Brettanomyces. Sure, it is possible that the Saccharomyces was introduced via bad technique, but my suspicion was that it was indeed a mixed-strain yeast. In yesterday's HBD, Jeff says that suppliers had been informed all along that this is a blend and not a single-strain yeast. I am a retailer and I had never received any such information until recently. A few weeks ago, I received a letter stating that this yeast was always a mixed-strain yeast and that only the name was being changed. My own personal tests with this yeast when it just came out (not microbiological, but rather by brewing with it) indicate that it did not contain a lot of Saccharomyces and, in fact, *acted* as if it was 100% Brett. Perhaps initial packages were 100% Brett and this was later changed. Now, I have been dealing with Wyeast for over three years and their quality, customer service and responsiveness are probably the best of all my suppliers. If there was some change in the yeast, I'm certain that it was done with good intentions. If there was some mislabeling, I'm certain that it was done with no intent to fool anyone. If someone suspects a problem with a particular batch of yeast, I would recommend contacting your supplier first (even though I would contact Wyeast also) -- at the least, it allows them to pull the allegedly bad yeast from their fridge till they resolve the issue. In the case that spawned this discussion (mixed-strain or single-strain) I think that contacting Wyeast before posting might have been a more prudent approach. Even so, this is all based upon my peripheral knowledge of this situation and there may be other facts which complicate this issue. Incidentally, I don't keep the packages till the batch is in the bottle, so I write down the date code from the bottom of the package in my logbook, just in case there is a problem. Here's the bottom line for me: I have brewed over 170 batches of beer and cider, at least 140 of them with Wyeast yeast... the handful of problems I had among these batches were traced back to something *other* than the Wyeast. Honestly, I'm a very satisfied customer and end-user. Al. Return to table of contents

Lord, that's a sweet brew, both of them. About 6 weeks ago I made the 90 Schilling Scotch Ale, following the recipe (page 115) pretty closely. It's aging in a keg now, so I managed to pull a taste without disturbing it too much. It was still a little green, but is coming along nicely! Bitterness dominant in the flavor profile? No. Appropriate for style? I think so. Details... OG=1.078 FG=1.020 1% roast barley 99% pale malt 0.75 oz Chinook (10.9%AA) for 60 min. (just over 28 IBU, as I calculate it). Key point: pull the first (strongest) runnings and carmelize them during sparge. Give it a try! I'll be making this one again.

I am a novice, extract-only brewer looking to do my first porter. As I haven't used honey yet are there any specific varieties that lend themselves better to brewing than others? Any help would be appreciated. I'd also like to add the information on the HBD has been incredibly useful. Thanks! Mike Return to table of contents
Date: Sat, 11 Nov 1995 22:23:42 -0700 From: flemingk at USA.NET (Kirk R Fleming) Subject: Alcohol Calculations In #1881 Todd (troat at one.net) was getting disagreement in percent alcohol calculations when using the three scales on a typical hydrometer. He was using the following formulae to compute percent alcohol by volume (abv): Balling: (Balling1-Balling2)(.42)(1.25) Pot Alc: %1-%2 SG: (OG-FG)(105)(1.25) and he got the following results (I've done minor editing): > My last batch calculations were as follows: > Balling: (14.75-4)(.42)(1.25) = 5.6% > Pot Alc: 7.5-1.0 = 6.5% > SG: (1.060-1.015)(105)(1.25) = 5.9% I don't know where the constants in the above two equations come from, but if you use those given in the Summer 1995 Zymurgy magazine (p. 57) and a very good conversion approximation for Plato to sg, you may get better agreement in your numbers. From the Zymurgy article: 76.08(og - fg) A%w = -------------- (1) 1.775 - og and percent alcohol by volume is: A%w(fg) A%v = ------- where 0.794 is the density of alcohol (2) 0.794 Substituting (1) into (2) gives: 95.82fg(og - fg) A%v = ---------------- (3) 1.775 - og Combine eqn (3) with the following Plato-to-sg approximation: sg ~= 259/(259-P) (4) and using P1 to mean original and P2 to mean final readings, simple substitution is (3) yields the ridiculous: 95.82[259/(259-P2)][(259/(259-P1)) - (259/(259-P2))] A%v = ---------------------------------------------------- 1.775 - 259/(259-P1) 95.82*(259^2)*(P1-P2) = ---------------------------- (5) (259-P2)^2*(200.7 - 1.775P1) In the table below created from eqn (5) the top row is the final and the first column the original Plato reading: 1 2 3 4 5 6 7 8 9 - --------------------------------------------------------- 6 2.5 2.0 1.5 1.0 .5 .0 --- --- --- 7 3.1 2.6 2.1 1.6 1.1 .5 .0 --- --- 8 3.6 3.1 2.6 2.1 1.6 1.1 .5 .0 --- 9 4.2 3.7 3.2 2.7 2.2 1.6 1.1 .6 .0 10 4.8 4.3 3.8 3.2 2.7 2.2 1.7 1.1 .6 11 5.3 4.8 4.3 3.8 3.3 2.8 2.2 1.7 1.1 12 5.9 5.4 4.9 4.4 3.9 3.4 2.8 2.3 1.7 13 6.5 6.0 5.5 5.0 4.5 4.0 3.4 2.9 2.3 14 7.1 6.6 6.1 5.6* 5.1 4.6 4.0 3.5 2.9 15 7.8 7.3 6.8 6.2* 5.7 5.2 4.7 4.1 3.5 16 8.4 7.9 7.4 6.9 6.4 5.8 5.3 4.7 4.2 17 9.1 8.6 8.1 7.5 7.0 6.5 5.9 5.4 4.8 18 9.7 9.2 8.7 8.2 7.7 7.1 6.6 6.0 5.5 19 10.4 9.9 9.4 8.9 8.4 7.8 7.3 6.7 6.2 20 11.1 10.6 10.1 9.6 9.0 8.5 8.0 7.4 6.8 Interpolation between the two asterisked numbers for Todd's og = 14.75P and fg = 4P yields 6.1% abv. Even though sg 1.060 really equals 14.66P, and 1.015 is closer to 3.83, since Todd's reading errors were consistent the results are the same: abv of 6.1%. The calc using eqn (3) above and sg's of 60 and 15 yields 6.1% abv. KRF Colorado Springs Return to table of contents

CO2 cylinder was made by the same >>French firm that makes his scuba tanks. Is it possible to >>use such tanks for CO2 ?? Has anyone out there done this ?? It's been years since I dived last, but I believe that the valve threads in CO2 and air cans are different, so that the regulators couldn't be mixed up (possibly suffocating a really dumb diver). That would make it difficult. Getting a scuba tank filled with CO2 might present it's own interesting challenges at the filler's, too <g>. Return to table of contents
Date: Sat, 11 Nov 1995 16:11:32 -0500 From: KennyEddy at aol.com Subject: Ain't That Peculier A few weeks ago I mentioned an Old Peculier clone that I had made. I finally got around to doing a side-by-side comparison with the "real thing". I'lll try not to hurt myself patting myself on the back, but I came VERY close! The recipe is a melding of Mike Fertsch's (FERTSCH at adcl.RAY.COM) Cat's Meow recipe and the late Dave Line's recipe from "Brewing Beers Like Those You Buy", as well as various tips & ideas I have picked up here and there. Color: Mine was slightly (but noticably) darker. Adding a bit of tap water to lighten the color eventaully resulted in identical hue and intensity. *Aroma: Almost identical. Both had the same rich buttery nose, but Old Pecilier was slightly sweeter smelling. *Flavor: Again, almost identical. The level of bittersweet molasses flavor was so close between them. In actuality, with my eyes closed I couldn't tell which was which. *Suggested tweaks to recipe: Since the color was darker but the taste was the same, I think I would reduce the dark malts by maybe an ounce or two to reduce the color and to let the treacle's aroma come through more without greatly affecting the flavor. This should bring the recipe about as close as mere mortals can come. **Note: I used Lyle's Black Treacle and some demerara sugar which I brought back from a trip to Scotland. I don't know whether regualar molasses is close enough (maybe someone could comment) but supposedly treacle is available in the US from THE BRITISH EMPORIUM 130 N. Main St Grapevine TX 76051 (817)421-2311. I suspect you could substitute "sugar in the raw", turbinado, or candi sugar for the demorara. I wouldn't use brown sugar because the demorara is not as intense as brown sugar. Here's the recipe I used: 5 lb 2-row British Pale Ale malt ( at 80% eff) or 3.5 lb pale DME 8 oz black patent malt (steep 30 min at 155F if using DME else mash w/pale malt) 8 oz chocolate malt (ditto) 1 lb demerara sugar (add to boil) 4 oz treacle (add late in boil to help preserve aroma) 1.5 oz Fuggles (4.5%) 60 min (no finishing hops) Wyeast London 2 oz lactose (added to secondary during racking form primary) 65 deg F in glass primary 1 week, 65-70F in glass secondary till still & clear. Kegged & force-carbonated. OG = 1.044 FG = 1.011 Again, I would reduce the dark malts by 1-2 oz for "identical" color. Note that the malt should contribute only 33 points to the beer -- the treacle, lactose, and sugar contributes the rest. Go ahead -- get Peculier!

Date: Sat, 11 Nov 1995 20:11:02 -0800 From: Robert_Anderson at mindlink.bc.ca (Stuart Anderson) Subject: Hopping in Scotch ales Alex writes of the low hopping rate in Noonan's Scotch Ale recipes. As one who grew up in the Edinburgh area and passed many happy hours drinking pints of Campbell Hope & King's, Deuchar's, Fowler's, Usher's, Younger's, McEwan's & etc I can vouch for the predominantly low hopping. With the notable exception of the odd IPA, the light and heavy and draught ales were always malty. Perhaps something to do with the cold, damp environment and also ideal as a chaser to a wee dram. I have brewed the modern 80/- and 90/- all grain recipes of Noonan's and received good reviews from other transplanted Scots. My hobby was born out of necessity as here in Vancouver there are no Scottish ales available apart from McEwan's Scotch Malt Liquor which is hardly a session beer. Given the recent thread on roasting grains to amber and brown styles it would be interesting to attempt the 1850 recipes which call for up to 10% of these hard to find malts.
