Hello All - Does anyone know address &/or Phone #'s of homebrew supply stores in New York City? The Manhattan Yellow Pages don't show any, even though I've heard one is now selling supplies in Soho/Gr.Village. Any clues? How's that song go?

Is >this a real problem or am I worrying overly (I'm getting a homebrew to relax >with right now)? I also live in a house w/ a septic tank, and I was advised not to use bleach in cleaning the bathroom, because the bleach running down the drain would kill all the little septics :-). As for chlorinated water, I would guess it would be a function of what the percentage of water you are introducing into the tank is (as compared to the tank's capacity), and what the concentration of chlorine is in the solution. My gut feeling is that I would advise against it. My solution to this problem would probably not be apropos to you, as I live in the fairly rural area of Alabama that surrounds Huntsville, and my neighbors have not said anything to me when I dump my toxins into the drainage ditch at the edge of my back yard :-). I have not noticed any dead birds or two-headed squirrels in the area, so I don't think it is affecting the enviroment that adversely, but that may or may not be socially acceptable in your neck of the woods. If worse comes to worst, I can't remember the exact amount, but I believe it would cost less than a 100 bucks to have your ceptic tank drained and have them re-introduce the bacteria into the system. The builder of our house advised that you do that every 4 or 5 years, anyway. - -- /*****************************************************************************/ "We'll...do our best to help you port from | Gary Braswell, Systems Engineer an AT&T version to 4.2 BSD, but porting the| Intergraph Corporation other way is out of the question if many of| gary at rocker.b11.ingr.com the Berkely-specific system calls are used.| Engineering Dept. -M.

Date: Tue, 28 Jan 1992 9:45:43 -0500 (EST) From: R_GELINAS at UNHH.UNH.EDU (Russ Gelinas) Subject: Whitbread,ss spigot I've got a data point in support of G.Fix's assertation that the #2 Whitbread strain is a good fermenter. I made a strong ale (mistakenly, but that's not important) that had an OG of at least 1.060 and might have been over 1.100, depending on my extraction rate. The initial (first 1-2 weeks) of ferment were slow. Then, without any prompting from me, the ferment just took off, almost making another krausen head. It's been more than a month, and it's still fermenting strongly. I took a taste after about 2 weeks, and didn't like it: strong solvent/cloves/vinous flavor/aroma. If I remember correctly, that is characteristic of the #1 strain. Correct me if I'm wrong. Since then, the aroma has mellowed/sweetened considerably. I would expect the flavor to have similarly improved, although it may still need some aging. It was intended to be an Oatmeal Stout, btw, but it turned into an Imperial Oatmeal Stout. New category anyone? I'm also looking for advice as to adding a spigot to a stainless steel brewpot. According to the person with the MIG welder, the spigot has to be the same steel as the pot. True? And if so, where to find a ss spigot? Russ Return to table of contents
Date: Tue, 28 Jan 92 09:54:02 EST From: Tom Dimock <RGG at CORNELLC.cit.cornell.edu> Subject: Teel Pumps The Teel magnetic drive pump is a gravity feed pump, which means that the fluid must get to the pump on its own - the pump does not suck. This makes it suitable for setups where the pot or tun from which you are pumping has a bottom spigot. It won't work in the situation where you want to just drop the hose into the pot and start pumping. Another way of describing this pump is that it is not self-priming. The capacity of the pump is not really a problem, because you can put an inexpensive motor speed controller on it and slow down the pump. Oxidation should not be a problem - the pump body and impeller should not contain any air.... Return to table of contents
Date: Tue, 28 Jan 92 09:59:52 EST From: Tom Dimock <RGG at CORNELLC.cit.cornell.edu> Subject: Malt mill (ala JS) Well, folks, I did it. I sent my money off to JS and bought one of his bottom of the line (non-adjustable, hand cranked) malt mills. As was mentioned in the review several weeks ago, the aesthetics are kind of home-shop. However, in a nano-brewery where lots of the stuff is built out of plastic buckets and hacked up kegs, it looks right at home. The important part is the roller assembly, and that is a gem. It is very simple, but that does not mean it would be simple to build. I actually have all of the tools needed to do the job, (well, I don't have a foundry, but the parts Jack casts could as easily by fabricated from thick aluminum plate) but the time it would take me would be just too much. For $100, I'm willing to let Jack do it. Besides, he did the research - if I built my own, I'd probably have to do it a couple of times before I got it right. So how does it work? In a word, great. I ran several kinds of grain through it, and they all got a great crush. It is quick and easy. If what you want is Williams-Sonoma yuppie glitz, this mill will not make you happy. If you want a mill that is pretty much optimized for the small scale brew, this is your machine. IMHO the price is fair, and I don't feel ripped off at all. BTW, Williams-Sonoma has, among all the yuppie glitz, some very nice 3 liter canning jars for $6 apiece that are great for storing specialty grains, etc. I have no connections with Jack other than reading his posts (and yes I was pretty pissed last fall too :-) ) and buying his mill. I'm glad he's making them....... Return to table of contents

following this thread on how UPS is refusing to ship alcohol because it is company policy or whatever. This is garbage. Every month I recieve two bottles of wine and two six packs of beer from UPS (Taste of California and Beer Across America). UPS is the most inconsistent organization in the world. Supposedly, they have a signature for everything they deliver, but I come home from work all the time to find thing left on my porch in broad daylight. Sometimes the boxes contain very expensive things (software, china etc). The first time I got my shipment of wine from Taste of California, they made a really big deal out of getting an adult signature because the package contained alcohol. We called up and asked if we could leave one of those yellow slips with our signature on it and they said "Oh no, you'll have to sign in person for packages containing alcohol." So we went into UPS, signed andgot our wine. Well, the very next month, I come home from work and what do I find on my porch but two bottles of wine delivered from UPS WITHOUT my signature. Oh well, some much for company policy. The bottom line is that they will ship alcoholic beverages, but who knows what you have to go through to get them to do it. I think the easiest thing is to lie and tell them it's something else and avoid the hassle altogether.

If you find an eye doctor who can help with this problem, please let me know! I gave up on pH papers and bought a small digital pH meter from American Brewmaster. I don't remember the exact price, but it was under $50. It works well for me. I checked it on my marine aquarium, which has a known pH of 8.3, and it read accurately.

Date: Tue, 28 Jan 92 13:14:53 EST From: cjh at vallance.HQ.Ileaf.COM (Chip Hitchcock) Subject: re red star Russ Gelinas put in a "clarification" that Red Star \ale/ yeast was bad but the \lager/ yeast was "clean". This doesn't match the ZYMURGY lab results (in which RS and Vierka lager yeasts were rated ~1 out of 10), or an experiment in Boston in which the taste of OG-1.035 lager fermented with straight RS was instantly recognizable against more of the same wort fermented with single-cell-cultured Red Star. It appears that RS has high levels of contaminants that seriously affect the flavor of milder beers. Return to table of contents
Date: Tue, 28 Jan 92 08:57:57 EST From: loc at bostech.com Subject: Wyeast Package Problems With reference to the various experiences people are having with Wyeast packages, I noticed something new on the package. Yes, it is a bit strange but I do read packages. (8^) The new Wyeast packages contain new instructions on them. I understand that these new instructions are specifically intended to prevent the seam from failing. I noticed these new guidelines on a package of Danish lager I just used. The instructions now say to place one hand across the bottom seam of the package, holding it closed, while the other hand is used to just rupture the inner yeast packet. >From what I can gather from my sources, Wyeast fills the package from the bottom and this is the seam that is the most prone to failure. (I've had seams go before, but can't remember which one right now) *DISCLAIMER* the following statement is pure conjecture and has no base in fact. With that said, I suspect that the Wyeast people are working to solve the failing seam problem, but it is a harder problem than meets the eye. So check out the next Wyeast package you get that has a 1992 date on it and read how the directions have changed. If I learn any more, I will post the info. cheers, rogerl Return to table of contents
Date: Tue, 28 Jan 92 15:25:04 EST From: Jay Hersh <hersh at expo.lcs.mit.edu> Subject: AHA Nationals.. told you so... AHEM... not being one to pat myself on the back and say I told you so :-), but long time readers of the HBD will recall a discussion held several years ago caling for the creation of a tiered competition system where winners judged at a local or regional site would then be forwarded on to the National Round finals. At the time of the discussion the AHA competition was smaller, but there were also a lot fewer judges. I think back then ( late 87 or 88) the AHA just did not have confidence in anyone outside of Boulder to take these responsibilities. While much controversy raged around this issue (and some of us let our AHA memberships lapse over it...) time has vindicated those championing such a system. Now if the AHA would only actually let it's members have some real representation, say like having an elected Board of Advisors who actually had some authority to make policy over certain non-publishing issues (such as judging and competition policy) I'd be really happy. Still in all they have been a lot more responsive in the last few years accepting suggestions such as moving the conference around... - JaH - ------------------------------------------------------------------------ Hopfen und Malz, Gott erhalts Return to table of contents
Date: Tue, 28 Jan 92 16:39:24 -0500 From: djt2 at po.CWRU.Edu (Dennis J. Templeton) Subject: Botul-oops! After being notified privately that my recent post on the heat-lability of the botulism toxin was ion error (and particularly offensive to boot), I resorted to re-checking my facts (which should have been my first move). Facts: 1) The botulism toxin is quite unstable in boiling liquids; a 10 minute boil should thoroughly inactivate it. 2) Boiling does not kill the organism's spores; this requires at least pressure-cooker temps. 3) I think Jack S. was right on this one. (Argh that hurts!) There are bacterial toxins that are resistent to boiling (or pressure cookers) Staph toxin is one; this was the source of my error.

Date: Tue, 28 Jan 92 17:04 EST From: man at kato.att.com Subject: PSI/Temp chart for force carbonation I have the above mentioned chart in my hot little hands right now. In the past, I have force-carbonated mostly by luck, but I figured this chart would take the guesswork out of it. Well, I have a question. There is no mention of time anywhere. I went back through old digests and found no mention there either. If I want 2.4 Volumes in my beer, I can put it under 14PSI at 46F. But how long will it take? Obviously, it isn't instantaneous, but when it does reach 2.4 Vols., will it stay there and not take anymore CO2 into solution ? My guess is no, but I'm a programmer, not a cellar-master. So, what am I missing ? Mark Nevar "We all lead substantially diminished lifes when the beer we drink is as distinctive as Velveeta on Wonderbread." MJ Return to table of contents

After reading up a bit on the way septic tanks work, I became concerned that dumping the chlorinated water I use to sanitize will disrupt the workings of my septic system. Is this a real problem or am I worrying overly (I'm getting a homebrew to relax with right now)? My brother-in-law and part-time brew partner designs and builds septic systems. Since I recently acquired my first septic system I asked him about the effects that homebrewing might have on it. He felt that the small amount of chlorine involved (approx 2 ounces per five gallons to sanitize) would have no effect on the system's workings. In fact, he thought the yeast slurry which would be sent down would be an excellent treatment to keep the system healthy and functioning well (I guess he meant decomposition-wise). He couldn't comment on the environmental impact of the bleach.

I find it a bit strange that you would ask me questions in private mail and them respond with edited, out of context sound bites, in public. >>I for got the numbers but you would be amazed at the volume reduction just >>bringing up to 170 and letting it cool. It is on the order of a cup or >>more. That's about 4 times the volume of the alcohol in the beer so I think >>it is safe to say, it's gone. > * 1 cup per gallon is 6.25%; by volume, typical homebrew is 4-6% alcohol. (All US commercial figures are in weight%, which is lower; the traditional weak "3.2 beer" is 4% by volume.) * The composition of a vapor is governed by the concentrations and vapor pressures of the components of the underlying liquid. At 170F (76.7C), vapor pressure is 310 mmHg for water and 711 mmHg for ethanol, which means that the vapor should have ~2.3x as much ethanol as the beer---e.g., it will be ~10-15%v/v ethanol. All that is fascinating and elegant but, sheds not the slightest bit of light on whether it is or is it not, "safe to say, it's gone"? >>I am not quite sure why I started using Champaign yeast but it clearly is unnecessary. I use if for soft drinks because it is supposed to impart little or no flavor of its own and I happened to have some on hand when I started the NA project. >You should have included this info---if you want to be a momily-buster, don't spread any of your own.... Yes Mom, but I was just passing on a recipe that works and all of my reasons for everything in it would be a waste of bandwidth. Furthermore, you know how sensitive I am. Why did you ask the question in private and then scold me in public. Are you trying to stimulate another temper tantrum? From: djt2 at po.CWRU.Edu (Dennis J. Templeton) Subject: Practicing with poetic license >I see in the last HBD that ol' Jack S. has advanced from being simply the world's greatest brewer to being authority on community water supplies and medicine too. >Nay nay, I say. >Dear Jack; you cannot destroy the botulism toxin with a pressure cooker. >You are out of your league on this one. >dennis (M.D. Ph.D.) Not sure what "league" I am supposed to be in but if you are really an M.D., you provide an excellent reminder of why most intelligent people have little confidence in doctors. The following is from: Bacteriology, F W Tanner..... "The toxin formed by Clostridium botulinum is one of the most active poisons known. A small amount will cause death. Some fatal cases have been reported where a little liquor left on the tongue from tastina a portion of a bean pod caused death with typical symptoms. Experiments have shown that this toxin is quite susceptible to heat and destroyed by boiling for a few minutes." This information is so basic that even moms routinely demonstrate a far higher level of understanding than yours. Mom are advised to boil home canned foods for a few minutes before eating or tasting. The next time I need a doctor, I will make a point of checking out his "poetic license". From: sherwood at adobe.com Subject: sparging >How to provide sparge water is thus my problem. Dave and I got to talking, and he said that his water heater will get up to 150F -- if it got to 160F he would use that. I posted an article recently on the effects of sparging with boiling water and never got a single reaction and have suspected it got eaten. If you read my article on sparging temp, you will probably be disinclined to try to use water that cold. It is fairly easy to keep a kettle of water boiling for sparging if you are doing it at the proper rate. If you are using your kettle as a mash tun, move it off the burner on to a stool for sparging. You now have the burner available for heating sparge water. If you put a spiggot on the kettle used for boiling, the process becomes automatic. If not, just dip it out with a soup ladle. Every time you take out a ladle, replace it with a ladle full of tap water. The ideal solution is two kettles. I started with an enamel 32 qt and a coffee pot. I now use the enamel pot for mashing and a ten gal ss pot for sparge water which is then available for boiling when sparging is complete. js ~. Return to table of contents
