I absent-mindedly erased your email address, so I'll post the answer to your question about the Johnson A319 controller here. The temperature dial is analog - no digital display, unfortunately. You CAN trust the dial. I tested it for almost a week at various temps - dial setting and my thermometer matched almost exactly. If the LED isn't lit, then the temp at the sensor is what the dial reads. All this is assuming that you haven't dialed in a wildly high differential. I have been running mine at the factory setting of 1F. If I find that the compressor is kicking in too often, I may bump it up to 3-5F. So far it hasn't been a problem at all, tho.

Keep heating until it turns a lightly burnt colour. Let it cool, break it up and taste it - thats caramel. It imparts colour in smallish quantities and taste in larger quantiies.

I was at K-Mart last night (in the Northern Virginia area), and saw that they had King Cookers on sale for $38 (normally $48). I believe it's their end of season, and are trying to get rid of inventory. The model number was PK80 I think. It's the same one I finally bought. It has an adjustable air supply intake, which means you can turn down the gas flow thru the regulator and still get a good blue flame. I previously bought a PK90 (?) King Cooker, which is a jet cooker version, which is harder to control gas flow. After testing it, I exchanged it and bought the PK80. I used the PK 80 last weekend on my first all grain. It did a nice job. Standard disclaimer. Good Brews! Art McGregor (mcgregap at acq.osd.mil) Return to table of contents

Simply find a really good import beer store and buy a 22 oz. bottle of Taj Mahal beer. One swing and your desires for this type of beer will be forever altered. (I do suspect that it is "cow dung" rather than peet though.) On the subject of starters, visit your local university and pick up a text on either mycology or microbiology, they reference many nutrient broth formulations ideal for the growth and reproduction of brewers yeast. Diffco is a company that is a common supplier, I often use their nutrient potato broth product with success, to keep my cultures going. Return to table of contents
Date: Fri, 2 Sep 1994 09:02:55 EDT From: PSTOKELY at ea.umd.edu Subject: Dos Equis My message to Darren Tyson bounced, so here: I'm an all-grainer, and I use Hallertau hops in my approximation of Dos Equis, since it is a vienna lager style. The grain bill is mostly 2-row lager malt, 25% vienna malt and 10% crystal malt. A friend has used Brewferm's "Cervesa Style Lager" brew kit with 2 lbs. amber dried malt extract and the kit yeast, and has yielded a beer embarassingly close to mine. (Like most all-grainers, I cannot ever admit that extract brews are just as good as full mash brews.) The only Mexican beers we seem to find here are Tecate, Corona and XX. XX is by far the best of the three, IMHO. Good luck! Paul S. in College Park, Maryland "You speak in strange whispers, friend, are you not of The Body?" Return to table of contents

The purpose of the flame is twofold: 1/ To heat strongly and locally those areas of working implements that may become contaminated: lips of bottles, inoculating loops, pipets, etc. The heat kills the bugs locally, without having time to spread to the rest of the object, which would make it impossible to handle. 2/ To ignite the alcohol that is used to sterilize such instruments as spreaders, scrapers, policemen, etc. The alcohol burns away from the object, and thus does not heat it. The same result could be achieved by letting the alcohol evaporate, but it would be more difficult to make sure that there are no droplets left. Besides, it is more fun to wave flaming spreaders around. All else is urban folklore. A Bunsen burner is not a laminar-flow hood. Pierre Return to table of contents
Date: Fri, 2 Sep 1994 07:37:22 -0700 (PDT) From: Domenick Venezia <venezia at zgi.com> Subject: Yeast reproduce anerobically too! Someone, somehow, somewhere started the myth that yeast can only reproduce aerobically and this has been perpetuated in post after post. YEAST CAN REPRODUCE DURING FERMENTATION!! OXYGEN IS NOT REQUIRED FOR YEAST REPRODUCTION! The randy little fungi does it in both modes until they start to starve. (Okay, okay, "randy" above implies sex, and generally yeast strains are monoclonal so they are not reproducing sexually, but it made for a good line, and I am not beyond bending the truth a bit for a good line, e.g., "Hi Beautiful, my name is Bill Gates.") So why is it good to aerate your wort? Why do stuck fermentations result from under aerated wort? By shaking the starter you will be introducing a constant supply of O2 into solution and thereby forcing the yeast into the Krebs cycle of respiration. You really don't want your yeast into the Krebs cycle because they will use up all the O2 doing respiration when you actually want the O2 later for ergosterol synthesis. Ergosterol?! Ergosterol?! Ergosterol is a cholesterol like steroid that the yeast synthesizes and puts into the cell membrane to counteract the effects of ethanol on the membrane. O2 is necessary for ergosterol synthesis and if it is not available when the yeasties decide to make it you will get a stuck fermentation because the yeast, being unable to synthesis the antidote, will poison itself at relatively low concentrations of ethanol. Also, remember Jack Schmidling's lag-time vs. aeration test of last year? (Thanks Jack) Jack's results were largely shouted down but IMO never refuted and need to be explained and taken into account. In short Jack found NO effect on lag-time by level of aeration. BIG SHOCK! Counter- intuitive. Outside the common pale. So is curved-space-time, but we all believe in that, don't we? So what causes lag-time? 2 things: environmental shock and underpitching. Environmental shock is the effect of changing media conditions rapidly for your yeast, like what happens when you pitch from a high cell density starter to the carboy. Rapid changes in osmotic pressure, temperature, crowding, etc., all tend to stun the yeast until they adjust. In my brewing experience the most important factor is temperature. Given similar temperatures shock times are pretty short - minutes rather than hours - THIS IS A GUESS. Underpitching means not enough yeast to give visible activity after the environmental shock is over. Reproduction needs to produce enough yeast to make visible activity. Underpitch times can be long, a day or more if pitched only from the foil pack, a couple hours or less if pitched from a good dense starter. I have always suspected that wort can be over-oxygenated but have no data to backup this suspicion. If anyone has information/experience on over-oxygenation jump right in. Again, IMO a good nitrogen source for the yeast starter is very important. A source of nitrogen is required by yeast to synthesize amino acids and hence to produce proteins. Without protein production no reproduction is possible. I add Yeast Nitrogen Base (YNB) to my starters and have noticed great improvements. YNB contains 5g of ammonium sulfate per liter, microgram levels of the B complex of vitamins, various trace elements, plus other inorganic salts. I use 6.7g YNB/liter. Wow, gangbusters. A complete analysis of the product down to the microgram level shows the stuff is safe. Try the yeast nutrients sold in home brew stores. Ask the shop owners to find out what is in them. That's my rather more than two cents worth on the issue. Hopefully, a lively discussion will ensue. Imbibe wisely and often, Domenick Venezia ZymoGenetics, Inc.

It is not to make a small quantity of beer. . . . . "I suspect many "recipes" for starters are based on recipes for beer. Can some of you experts out there comment on how to judge a good starter from easily observable parameters? " Well, I'm no expert, by my lights. But I think I can answer this. Ignoring the possibility of infections, I think the vigor of a starter can be measured fairly easily, not by its specific gravity, but by the amount of co2 it emits per increment of time. The more co2 being emitted, the more fermentation occurring ... and the fermentation is strictly a consequence of the number of active yeast cells. This translates into a count of bubbles per minute at your vapor lock. I prefer vapor locks without moving parts, IE, the pure "S"-shaped lock ( as originated by Pasteur, I believe ). Without moving parts, there are only two dynamics ... the gas going out, and the liquid it is passing thru. This gives the observer a consistent and steady bubble count which is so reliable, statistically, that ity may be used as a crude clock ( relying upon the same statistical dynamics as a water clock, now that I think of it ). So why not grab a stopwatch, and measure how fast the vapor lock is bubbling ( I always sample at least three or four bubbles, than divide the interval elapsed on the stopwatch by the number of bubbles, to get a precise answer ), and use that as your metric for measuring when the starter batch is ready to be brought into conjunction with the wort ? Note : this method can be used throughout the entire fermenting process, and, in fact, it is entertaining to chart the rise and fall of the bubble rate across time and cycling temperatures. This might make an excellent little demonstration of some sort, in a science class ... - -- richard Law : The science of assigning responsibility.

"Date: Wed, 31 Aug 1994 03:54:52 -0400 (EDT) From: Emuel Aldridge <ealdridg at moe.coe.uga.edu> Subject: Homegrown hop curing. "I'm sure this question has come up here before. What's the best way to cure hops? I have a 12X12 hop trellis that produces a lot but I don't know the best way to process them." Well, there are a couple of approaches to drying 'green vegetable matter'. In general, you want something that (a) raises temperature slightly, and (b) decreases humidity slightly, and (c) keeps the air moving slightly. The best solution is to build a drying box. Such a box has a light bulb in the bottom, sliding trays made of screen on wood frames, holes in the bottom for air to be drawn in and at the top for hot air to escape, or a small fan, perhaps. The light bulb provides a source of heat, and the hops are scattered on the trays, and shaken periodically, until they're reasonably well cured - then they may be bottled, or bagged, and frozen. A low-end alternative is to build such a screen above a water heater or other warm spot in the basement or garage, if such is available. The oven - turned off, warmed only by a pilot light - is also a good alternative. Tape a note on the switch that turns on the oven, or you will be very sorry ... (-: I decided to post this because there are probably a lot of people who are at the same crossroads, this week ... "Also, is it necessary to cure hops before using them or can you just boil them up green?" I would think that if you boiled them up green you'd get chlorophyll- -flavored beer, rather than hops-flavored beer. The whole idea of "curing" is to get the chlorophyll to slowly break down into less detectable components ( I surmise ) and to extract the water, also, of course, so as to inhibit infections. ( I would think that going into some detail on excatly what "curing" is might be good, in the Hops FAQ, if it does not already do so. ) - -- richard Law : The science of assigning responsibility.

Date: Fri, 2 Sep 1994 14:04 EDT From: HEWITT at arcges.arceng.com Subject: Real Homebrewing This topic has had me thinking too long- it's time to unload. We live in a rural area, and rely on our own well and septic system for modern conveniences. Each time I pour a homebrew, rinse the bottle, and pour the yeast layer down the drain, I think -- this is good, it should help keep the microorganism cycle going in the pipes and downstream in the great unseen reservoir. Then I wonder why I shouldn't pour the post-ferment yeast layer in the toilet and skip the Rid-X (tm)? Anybody done any fermentation studies using brewing yeast and you know what? Not being a microbiologist I'm sure I have my micro-beasts confused, but QUESTION: should I expect any benefit in terms of enhancing the solids breakdown by introducing spent brewing yeast into the tank (or is it detrimental)? I suppose I could improve conversion and, let's say, use electric resistance tape heaters and a modified Hunter airstat to keep the toilet bowl temperature at 148 deg F, add an insulated seat, and put a 90 min delay timer on the flush mechanism.... Even so, it seems a terrible insult to the precious yeast after taking such pains to maintain absolute purity, watching it perform such a huge task in the fermenter solely for our pleasure, then sending it on to the dark interior of the underground in the most undesirable medium imaginable. A proper burial in the garden would seem more appropriate. But if practical, why not?

I know of one local brewpub that started with what seemed like tiny amounts of this malt and then couldn't sell the beer. Seems that people weren't partial to drinking diesel fuel. As others have pointed out, this stuff is intended to end up in Scotch *whiskey*, not Scotch ale. There are several distillations between the mash and the mouth in that process. I'm still trying to figure out why the AHA says that Scotch ales may have a smokey taste; it's certainly nothing I've ever encountered int those beers. ========================== In respect to yeast starters, I would strongly recommend picking up some brand of enriched nutrient. For years, I've been making a simple starter medium of DME and yeast nutrient (as sold by F H Steinbart). In the last week, however, I used a fortified nutrient for the first time and the response was truly astonishing. I got much more vigorous growth, fermentation (a real head!) and now have a huge supply of yeast in a very short period of time. In the interest of non-commercialism, I won't recommend a brand, but I suspect that most of these blends will achieve the same effect. This one happens to be the one used by a yeast lab to culture up their product -- as someone else has said, this stuff does not replicate ordinary wort. In fact, you wouldn't want to drink the result at all. Lots of minerals, I believe, and not tasty ones at that. - --Jeff Return to table of contents

Before you all run out and get >a Corona, please read George Fix's article on Crush Quality in the >same issue of Zymurgy as the Mill Comparison. Then decide which mill >you would like to buy. I believe that George Fix' article is a basic recount of what deClerck and Dougherty have stated as ideal crush qualities. It is the article about mills that really begins to focus on how those criteria come to bear on the crush quality of commercially available malt mills for homebrewers. The visual crush quality results of the various mills seems to disfavor the Corona. This may have something to do with the fact that is is believed that damaged husks will extract undesirable husk phenols and tannins. I do not know. I think it is still conjecture about the real result: beer. I think this whole thing may need a little more work from the AHA Research Department as to how commercial hb mills relate to finished beer quality. Until then, I will not be purchasing a "high-end" mill for throughput only. I have sturdy arms and plenty of time.

When filled this setup is extremely stable, and it has the additional advantage of holding the heat better than the Camp Cooker 170,000 btu setup which I also use. The skirt on the bottom of the keg fits over the burner ring and thus it cannot slide. It would take a very heavy klutz to knock it over since with 10+ gallons it weighs about 150 lbs.

As I understand it, historically, flaming was used to burn off the cotton fibers that remained in the neck of flasks after the *cotton* plug was removed. Now that foil or plastic caps are commonly used, this is no longer necessary. I still flame the flasks as a habit. I think it is a good habit, not to create updrafts of air out of the flask, but to sterilize the lip in case I accidently touched it when I was removing the cap. I don't flame between plates, but only after I remove the cap. BTW, this is not the only place I have heard the "updraft" explanation/excuse, but from my experience, it is just a bunch of hot air ;-> My "credentials": I have poured well over 10,000 plates (yikes!) with very few contamination problems...

Webb <rbw1271 at appenine.ca.boeing.com> writes: In HBD #1514, Clay Glenn reports on his experiments with heating beer to drive off alcohol. He has several questions that need answering, and here are my lucky guesses. One question he had was how much alcohol (if any) he got rid of. I question him back: what were the final gravity readings of the two batches? As alcohol is less dense than water, it should be (theoretically) easy to determine the difference in alcohol from the difference in specific gravities of the 'boiled' and 'not-boiled' beers. Unfortunately, I didn't measure the gravity after the post-fermentation heating. However, I am curious how one would use this information. For example, If I knew that the fermented beer measured 1.010 before the second heating, and 1.015 (or U-pick a number) after the second heating, how would we use this information to determine the alcohol level? Since I know some water and maybe a bunch of alcohol evaporated (along with all my CO2), how would we translate the specific gravity data into a final alcohol level? Any takers on this one? - -- \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\ O >>> Clay Glenn clayglen at netcom.com >>> /|\ /////////////////////////////////////////// /'\ Return to table of contents

By the time I was ready to drink this ale (at home) it had gone flat. So, i added 1 tablespoon of cornsugar to the gallon of ale. The carbonation came right up but there is a very strong lemon taste now. This isn't just 'Citrusy', it's LEMON. The only guess I have is the temperature in my house was too warm (about 80F).

Frankly (pun) I thought you were joking. Being "significantly happier" means different things to different people but your comment seems to re-inforce my very negative opinion of the article. The crush quality was the only issue that was actually evaluated and they came up with a toss up. The "details" that make people significantly UNHAPPY when using a mill were glossed over to the point that your conclusion was the only one that could be drawn from the words, i.e., might as well buy the cheapest. js Return to table of contents
Date: Fri, 02 Sep 94 23:44:50 EDT From: WLASKA at aol.com Subject: Pilot Homebrewing System I have acquired three sankey kegs and trying to put together a modified "Brew Magic" system without the $3000.00 outlay. I have put to paper a plan that should do the trick, but need some advice. I am looking for a false bottom to use in the kegs and have seen some advertisements on them. Any comments on which ones will work, especially in the sankey? Next, I would like to have it set up so I can pump the hot water from the Hot Liquor Tank to the Mash Tun along with the hot Sparge water...this should not be a problem. I would like to use the same pump to pump the wort from the Mash Tun to the Kettle for boiling. Is there a pump that I could use which would allow me to do this? Thanks for any help on this.

Date: Sat, 03 Sep 1994 02:42:10 -0700 (MST) From: "Steven W. Smith" <SYSSWS at gc.maricopa.edu> Subject: Full volume boils and such First my qualifications: I do computer things. I'm not a professional brewer, but I've heard one do radio commercials. Other people have tried my beers and smiled. :-) Yippee-yi-aye! (it's the West, I'm entitled) I've passed another brewing milestone; the (holy and long-coveted) Full Volume Boil in a cutoff 1/2 bbl SS keg! I'm definitely pleased, and am prepared to share some observations on this and other zymurgistic events. First, the keg's legal. I swear. $20. Cutting the top out wasn't harrowing. Traced a circle to follow (Ha!) then drilled 2 holes side-by-side to allow the saw blade in. Used up 4 24 TPI blades (TPI==teeth per inch) and about 30 minutes, including breaks and being really careful not to dismember myself. *Do* have hearing and eye protection for that part. You'll be glad because it makes you oblivious to all the barking dogs in the neighborhood. Having received a 170,000 BTU King Cooker for Father's Day, I was ready to party. I started out with 6 gallons, which boiled down to just under 5 in about an hour. My hop utilization was noticably improved (like doubled??). I found that 2 ounces of hop pellets will settle nicely into the concave bottom of the keg! I just stuck the racking cane all the way down next to the side of the keg and left most of the hops and hot/cold break behind. My immersion chiller I'd been using for 3 gallon boils was really inadequate - 20 ft of tubing - it took over an hour to drop it to pitching temperature. In other news, I've thrice verified that garden variety pantyhose when stretched over a racking cane Will Remove Hops and even Strawberry Particles from wort and must (proto-mead). My preferred racking/filtering method now is to: - cut off about 12 inches from one leg of otherwise unservicable pantyhose - boil the pantyhose in the microwave a couple of times (until clear water) - drop about 5-6 inches of the pantyhose through the neck of the carboy - secure pantyhose about the neck with a rubber band or two - place a washer-like object on the tip of the racking cane to increase the filter circumference. I cut about 2mm from the bottom of a small stopper for the washer. - insert racking cane and stretch to the bottom of the carboy - rack clear liquid with No Clogged Racking Cane :-D - if you have problems just stretch the pantyhose tighter. It Works Great. Do it, I implore you! Cripes! I nearly forgot about water chemistry!!! Temporary hardness - OK, I follow that part. Why must I boil *twice* to eliminate temporary hardness? Will the CA ions or cations or whatever bond with another componant of my beer rather than form a precipitate? Same question about chlorine, please. I really wanna know! I'll gladly summarize responses from any Chemists who may be tuned in. Oh yeah - I bought a 6-pack of Lemuel Addams Summur Wheet (look ma, no TM!) for $4.89. It's pretty tasty for what it is, and doesn't give me a headache like some (Budweiser!) commercial beers. Good job, Lemuel! :-) ... It's a joke, 'cause I know that deep down Jim's a great, fun-loving guy (looking nervously about). Aw geez, here comes my sig! _,_/| Steven W.

Ever since I constructed by counterflow chiller I have been getting a great cold break. Unfortunately, I can't get the break to go away! This stuff which looks like egg drop soup will not settle any further than the bottom 1/3 of my carboy. Chilling and swirling doesn't seem to make any difference, that trub hangs in there and won't settle to the bottom of the carboy. I should add that this never happened with my immersion chiller. I can't be the only one who has ever had this problem. It happens every time (high gravity or low) that I brew and use the counterflow chiller. How do you filter that stuff out of there? Please. Strain through a hop bag or cheese cloth.... run it through a 4 micron filter.... I'll take any tips from anyone who has gotten the "egg drop soup" out of their wort! pbrush at netcom.com Return to table of contents

I bought some of the stuff, but haven't used it because I didn't know how much of it to use. Can anyone out there tell me how much to use? I'd prefer an answer like "X teaspoons in Y gallons of water". Figuring out PPMs is something I'd rather leave to the laboratories. (Sorry if this is a repeat. I don't always read my daily HBD as closely as I should.) Thanks for your help. Tony McCauley -- afmccaul at rs6000.cmp.ilstu.edu . Return to table of contents

We too had trouble with #1514 receiving time-out, peer closed connection errors. I could not figure out why the HBD generated these errors and frankly I don't see how the HBD content could have affected transmission, but if you do know, I'd sure like to hear about it.

Date: Sun, 04 Sep 94 10:02:53 EDT From: BrewerBob at aol.com Subject: Tube bending and CA Pubs Tube bending - On the question of tube bending, one can bend a tube without kinking it simply by bending it around something of the approxiamte size of the coil desired. To make a wort chiller, for example, try a 6.6 pound can of Ireks Extract or a number 10 can. If you think about it, that is all the tube bending device is doing. It bends the tube against a known radius, only it is limited to about a 90 degree turn. By using a can, you can wrap 25 feet of tubing continuously. San Francisco Brewpubs - I wish to thank the many people that responded to my query on brewpubs in the San Francisco area. Your replies have helped me a lot in planning an itinerary that will include a few brewpub stops. Several folks asked that I relay the responses to them. I will do that as soon as I have summarized them all. Thanks again for your kind and prompt responses. BrewerBob at aol.com Return to table of contents
