I was going to Elgin on Friday to drop off some entries for the Spooky Brew competition, so I went ahead and stopped by Hennepin to see what they might have. The malt was in pretty bad shape. It had been sitting around since last January. I did manage to buy seven cases of new beer bottles for $2 a case. Anyway, here's the rest of the equipment listed for sale. 1-10 bbl Stainless brew kettl, gas fired 440,000 Btu's 1-10 bbl Staninless combination mash/lautertun 1 lot cartridge pediment water filters 1-Mueller 48 plate stainless wort cooler, heat exchanger. 1-portable centrifugal beer pump 4- Zahm and Nagel carbonators, master control unit, volume meter, air tester 1-Spedoni stainless steel diatomaceous earth filter with slurry feeder and pump 1 lot misc. equipment and parts 80 bags of grain malt of various brands ( its in bad shape, bugs and mice) 1-Pearson top box sealer/Elliot case gluer with Nordson hot melt 1- Crown Cork and Seal 28 valve filler with 6 head crowner 1- SJI twist rinser with feed table 1- Krones universal body and neck labeler 1- lot stainless steel table top conveyors 1- reconditioned inspection light 1- bottle coder 1- centrifugal beer pump 1- glue pump 20 bags Diatomite at 50 lbs ea. 23 boxes bottle caps 1- pallet beer bottles, ( minus the seven I bought) 1- pallet cardboard boxes 1- Champion model BR10-12 air compressor 1- cooling unit for cold room 39 half barrel kegs 3 quarter barrel kegs and also hand trucks, keg valves, water heaters, cabinets, sinks, and also office equipment.

Date: Sat, 25 Oct 1997 00:52:05 -0400 (EDT) From: AlannnnT at aol.com Subject: new contest categories Not being the most creative guy in the world, I've decided to get help from you all. I am now planning the Second Annual Homebrew Contest to be held next March. Our first contest was very sucessful but ordinary. For the next contest I would like to offer alternative categories for the really good beer that doesn't really fit well into the AHA style guidelines. I expect 125 entries. Please don't spam me for encourging 'punk' brewing. I love a hoppy IPA just like the next HBDer, I just think brewers make some funky stuff worth judging. And the beginers are discouraged from entering by the guideline's fine print. Current alternative category ideas include; 1.Beers brewed with at least 25 ingredients. 2. Don't know what it's called, but it tastes good. 3. At least 50 HBU's [or 60] 4. No hops at all. [How many spruce beers can YOU judge?] 5. My first beer. Well, as you can see I need help with interesting categories. I would like to encourage newbies to enter and I think the AHA styles are too rigid for some casual brewers. My experience last year was that many newbies had good beer that they entered in the wrong category because they didn't have the understanding of the guidelines they needed. Any help? private email ok. Thanks, Alan Talman Return to table of contents
Date: Fri, 24 Oct 1997 23:35:39 -0600 From: "M. Duppong" <mduppong at cyberhighway.net> Subject: Stuck Fermentation? I'm brewing up a Brewer's Resource Brewtek American Brown Ale, using the Wyeast that came with the kit- an American 1056 (I think). Primary fermentation was for 6 days at 68F. Racked to secondary, stored in a dark 64-66F closet. So far, I have yet to see one "blurp" from the airlock (from my casual observations in the last week). Me thinks the secondary is stuck. My question is, what do I do now? Do I add priming sugar and bottle? Do I try to get the yeast working again? If so, how? Mike Duppong Filer, ID USA Return to table of contents

The extra turbulent mixing during active fermentation increases the diffusion - doesn't eliminate it. However my main concern with O2 is after fermentation has slowed since presumably oxygen introduced during the ferment will be quickly used by the yeast anyway. > That said, the diffusion rate will be proportional to the >exposed surface area of the fluid. As such, a narrow "S" airlock may be >better than a wide concentric one for long term storage. The diffusion also is proportional to the concentration gradient from outside to in, so a rather long tube should help too. Surface tension tends to keep the bubbles large, so a considerable amount of liquid must move in a long thin airlock in order to pass a bubble. >CRC Handbook of Chemistry and Physics has some information on O2 >diffusivity in liquids. Unfortunately, neither water nor oil is in the >table, but FWIW the 02 diffusion rate goes down by a factor of two in the >series CCl4 > cyclohexane > ethanol.

My best guess is with an even higher dipole >moment than ethanol, water is a very good choice of airlock liquid for >keeping out O2. My CRC says that the order is cyclohexane>CCl4>ethanol, not your order (see below). Here I've included the dipole moments, also from the CRC. Dipole moment O2 diffusion 10^18 esu *10^5 cm^2/sec CCl4(carbon-tetrachloride) ~0 3.71 cyclohexane ??-low 5.31 ethanol 1.69 2.64 H2O 1.85 ?? Tho' dipole moment may be part of the story, I'd really like to see a more physical explanation than a trend drawn from 3 data points. Incidentally H2 has it's lowest listed diffusion constant for ethylene-glycol (dipole moment = 2.28) which has a much higher dipole moment than other more H2 diffusive solvents. >Other advantages of water include low toxicity, low volatility, no adverse >effect on heading, ... True, but there are many solvents that are non-toxic and non-volatile. Mineral and vegeable oils and gylcerine come immediately to mind. A properly designed airlock shouldn't allow for suck-in of the airlock fluid anyway. >CO2 makes a great blanket gas for protecting O2-sensitive materials, since >it's heavier than air. Cl2 is even heavier, and would easily sink through >a CO2 blanket. I wouldn't add bleach to airlock water. Nice myth - protective CO2 blanket, but this isn't how gas diffusion works. The CO2 and O2 (and N2) don't remain separate for long, but thru brownian motion mix in spite of the CO2 being heavier. I agree with the bleach comment - Cl has other negatives too, but the O2 does diffuse into the CO2 blanket a fermentor, and that the CO2 blanket diffuses out. Take a bucket and fill it with CO2 from a tank. Dropping a match in immediately after filling - the match will go out at it hits the CO2 'blanket'. Try it again after waiting a few tens of minutes - then the match doesn't go out. Putting a layer of water in your airlock slows but doesn't stop the diffusion process. If would be nice to find a better choice than water if possible. My real concern is the amount of non-enzymatic browning, and resultant staling that can place in a fermenter left for days/weeks after fermenation ceases with an airlock. The amount of browning that occurs is quite obvious - I've spoken with several other brewers who are also familiar with this effect. Since I travel quite a bit a fermenter may sit for several weeks to several months after fermentation slows. First clearing occurs as the yeast drops, then, a variable length of time from several weeks to several months the beer darkens remarkably. This doesn't have an immediate flavor impact, but isn't a good sign. Steve Alexander Return to table of contents

The major problem with converting a cooker such as this or finding a methane cooker is that they're both designed to be used outdoors. Neither has any means of shutting down the gas flow if the main burner goes out. This is especially scary when considering the amount of gas this could dump into your house in just a few minutes. 1 cubic foot of methane has slightly more than 1000 btu. So your 100,000 btuh burner would dump 100 cubic feet per minute. Find a burner that will shut down the gas valve if the flame goes out if you're planning on brewing indoors. ** The problem with the average family today is that it's=20 impossible to support it and the government on one income.

Date: Sat, 25 Oct 1997 16:06:05 GMT From: mra at skyfry.com (Matthew Arnold) Subject: Re: Extract good? >I agree with Al that you can make good beer with extract, but with the >available base malts I honestly believe that better beer is made all grain. > Plus look at the amount of satisfaction you get from doing it youself. I've been brewing with extracts for about a year now and have been quite satisfied (with one notable exception, which was a result of a procedural error, not extract itself) with the results. How is brewing with extracts not "doing it yourself?" I choose what extracts and in what amount, I choose the type of yeast (and I have used both liquid and dry), amount of specialty grains, amount and timing of hop additions. My beer is very much done myself. >Extract is a lazy way to make a batch of beer. If you really enjoy the >hobby then go for it make the best beer you can the same way the "Big Guys" >do. I'm sorry, but this is utter bunk. It is a cheap shot to call extract brewers lazy. Many have neither the time nor the money to invest in an all-grain system. Plus, if you're making good beer that you enjoy, why in the world would you want to make your brew day twice as long? Yet it is still possible, with quality ingredients and good procedure to make beer with extracts that rivals the best craft brews and, yes, even all-grain produced brews. Of course, this is coming from the same guy who said in HBD #2288 about those who might consider no-sparge brewing: >if you don't have the time to do it correctly why do you bother to brew >at all. If all you are looking for is alcohol then go and buy a cheap >jug wine. If you want a touch more then that then it is cheaper to buy a >bottle of Irish whiskey or some Jack Daniel's. Yes, that comment has been stuck in my craw for quite some time. Sorry about the tirade but this really annoys me. And, yes, I am going to try my hand at all-grain brewing as my previous posts have shown. Not because I feel I _must_, but because it is something I've always _wanted_ to try. I can very easily see myself brewing with extracts again, especially the recipes I've particularly enjoyed.

Date: Sat, 25 Oct 97 11:20:37 -0500 From: Paul <pedwards at iquest.net> Subject: White Labs yeast Chris White, president of White Labs, wrote in part to HBD: >The homebrew yeast vials we produce are equivalent to concentrated pint starters. >They are packaged at 1-2 billion cells per ml, so each vial ends up containing >30-50 billion cells. Right. And if people search the HBD archives, they'll find that Dr. White used to claim his vials of yeast had many times that amount until Jim Liddil and I proved him wrong. Now as to whether the amount of yeast in the tube is sufficent for pitching into five gallons of beer, I guess it depends on what you call "sufficent". Certainly White Labs is selling you more yeast than Wyeast, but neither is sufficient in my mind for pitching directly. But a 12 hour lag time is just not aceeptable in my brewery. Better than the 24-36 hours from a swelled pack of Wyeast, but not acceptable. Accepted pitching rates are from 0.75 to 2 x 10^6 cells per ml per Deg Plato of the wort (low end for ales, high end for lagers). So for 5 gallons (19 liters) of a 1.052 OG wort (about 13 deg Plato), I come up with 19000 ml times 13 times 0.75 x10^6 or 185 billion cells on the low end and about 500 billion cells on the high end. That's anywhere from 6 to 10 times the amount of yeast you're getting in the tube. High gravity beers need even more. Bottom line, make a large enough starter to get the quantity of yeast you need, oxygenate it well, and oxygenate your wort well, too. You'll be glad you did. If you can't or won't make a starter, just rehydrate a couple or three packs of Nottingham dry yeast. Just as all-grain beers aren't necessarily better than extract beers, liquid yeast, improperly handled or used, is not necessarily better than dry. - --Paul Edwards Return to table of contents
Date: Sat, 25 Oct 1997 13:05:53 -0400 From: i.brew2 at juno.com (David Blaine) Subject: 180 lbs of barley A co-worker told his farmer brother in law that I would like *some* barley when he harvested this fall. Said in law showed up at work with *three* 60 pound sacks and relieved me of $20. I don't mind the dough, but I haven't a clue as to how to put any of this to good use. I am an extract brewer, and thought I might be able to germinate some of this and make crystal malt with it to go with some of my ale recipes. I am also willing to experiment in using it as a base malt for some trial and error brews since it's there and it's paid for. I need some ideas on malting, drying, and step mashing. I have done single infusion mashes before in partial mash pilsners. The first time I tried to mash this I screwed up and it went bad. I saw rootlets but the "acrospire" never seemed to grow. Now I think someone said that the acrospire grows inside the husk, so it may have been fully modified and I didn't know it. After a couple of weeks the whole thing just smelled sour. I will add that this crop was accepted as brewing barley, a good colored six row american, not feed barley. I would like to find out what I can do with equipment I have on hand to use this grain over the winter. it is in cool and dry storeage now in the garage. Private E Mail fine.

Brew Masters, With all of the talk about brewing water and my curiosity for knowledge I could use some help as I am water chemistry challanged. I have a copy of the treated water quality report (WQR) from my local water quality lab but this thing is forty pages long. I have narrowed it down to one page that looks like it pertains to the information I need. By looking at Brewers Workshop (BW) I see the following water chemistry fields for Tap Water Ions: Ca, Na, Mg, Cl, SO4, CO3, HDNS and TDS. I have all the numbers I need except for CO3. Now in the WQR under "General" Ca is expressed as CaCO3 (82 mg/L) and under Metals there is Ca (31.2 mg/L) by it self but no CO3 anywhere else that I could find. BW has two fields one for Ca and one for CO3. How do I figure the CO3 from the CaCO3. Do I just subtract the Ca amount from the CaCO3 or is it more complicated than that. Is there more information required to figure this out.

While you can add whatever spices in whatever way you want (almost all ways work), a best bet is to brew a tea you can add at bottling time. You can control the effect that way and add just to suit your tastes and no more. Adding to the primary or secondary, while it makes for a wonderful smell in the house, probably drives off most of the aromatics you would want to preserve. The same can be said for adding pre-boil or during the boil. You lose more than you gain I would think. If you are REALLY worried about sanitation, what you could do is to place the spices in a canning jar with the water and pressure can them long enough to sterilize the tea. You do it just as if you were canning vegetables.The spices stay in until you are ready to add the tea at bottling time. Most of the aromatics will still be there and the tea should be about as sterile as you can make it. Can't say I've tried it, but its worth thinking about if you have access to the pressure canner and nothing better to experiment with at the time. - -- <Ed McCormick - e-mail: emccormick at usa.net> Return to table of contents

Was nervous about putting yeast in that much sugar water and capping it up. Only used 1/2 tsp. of dry ale yeast and mixed it up and bottled. Waited for a few days for explosions and then waited a few weeks to try it after nothing blew up. When we sampled there was NO carbonation at all. Never developed any over 4 months the stuff was arround. Still made fairly good root beer floats. Now I want to try this again WITH carbonation. So will someone tell me how to bottle condition this without blowing up the basement? How much yeast can I / should I use? What kind? Why doesn't it blow up? I will be storing at about 65 degrees F. and don't have room to refrigerate it. Private E Mail OK.

It was a real eye-opener! First, I checked it in distilled water, something I had done before: 1.000, just like it should be. Then, following the instructions in the article, I measured 50-g NaCl into my 1000-mL volumetric flask (Class A). The gravity should have read 1.050, but instead read at 1.035. Not even close. So, my question is, do I go out and buy a new hydrometer (actually, I'd get two, one specifically for measuring F.G.), or do I spend the extra money and get a refractometer? It seems to me that the biggest advantage of getting a refractometer is its smaller sample size--I could take readings at any stage in the brewing process without having to remove a 250-mL sample each time.

Plus look at the amount of satisfaction you get from doing it youself. Extract is a lazy way to make a batch of beer. If you really enjoy the hobby then go for it make the best beer you can the same way the "Big Guys" do. - ----- To say that extract brewers are using the lazy way, is to say that bakers are lazy because they don't grind their own flour. Extract and partial mash brews can be very good; I'm sure I've seen Gold Medal NHC winners that are extract, and I know personally they are among the other medals. I can say that all-grain beers are among my best beers, and they also have been among my worst beers, though my (by brew-partner and I actually) best award was for an accidental partial mash (I thought I was steeping but later learn the grains I used had starch to convert. Since I don't think I was a starch beer, something converted.) When an extract brewer uses the lightest malts, and darkens and flavors the beer with specialty grains steeped or partial mashed, uses unhopped extract, liquid yeasts with starters, proper aeration, water preparation, keeps the fermentation temp constant and low, uses finings, and more, I would not call that person lazy. One can get plenty of satisfaction from the work. Does one call an all-grain brewer who filters and force-carbonates lazy because they take the 'easy' way out? The last pair of beers my brew-partner and I made were extract/specialty (two in a day); the beer before was all grain (a triple decotion), it depends on the time one has and the amount of hassle one can put up with, and whether to try and convert a former good recipe to all-grain. Good beer can be the result either way. Dennis Waltman Return to table of contents

Well, Mike, as you know from beer brewing, yeasts can produce a variety o= f tastes in beer, depending on the strain and the nutritional content of th= e wort. If you used Montrachet as the strain of wine yeast, the sulfur sme= ll is a typical result of this yeast. In winemaking, I avoid it by racking early and often as I believe it is subject to autolysis and produces hydrogen sulfide. In winemaking, for extreme cases, I sometimes resort t= o a copper sulfate treatment , but often it disappears over time as the win= e is racked. I can't promise you the same here, since you probably bottle conditioned and have a layer of yeast in the bottom of the bottle. It may= get worse with time. = For those sparkling barleywine makers and mead makers.

Nine, mein freund! Actually it is made by heating Graywacke rocks to 1200'C then dumping them into the boiling tun and allowing the wort to boil and caramelize onto the rocks which are then allowed to cool and be returned to the fermenting wort.

I really think I shouldn't expand a thread so = unsolicitedly "colorful" as Steve Alexander's (HBD #2539) posting = about airlocks, but with the questioner (Joshua Penney) in mind I = will carry on. Being forced by geographical isolation (I live and = brew in Venezuela -not a single homebrew supplies retailer around = here yet-), I had to explore all possible alternatives to a costly = overseas cargo and customs deal before buying any accessories = States-side for my recently found hobby. By a lucky chance I = happened to get in touch with a laboratory glass artisan in the = capital (Caracas, pop. +10 MM), who hand makes and repairs all type = of lab glassware. Put to the question of reproducing my broken "S" = type glass airlock, the man told me he could make me a much better = and smaller airlock. Next day, Gabriel (his name is Gabriel Bukor), = had made this incredibly simple device that he says is lab tested to = withstand a lot more intake pressure than what my 4,75 gal. glass = carboy setup could generate by cooling after initial fermentation, = without sucking any barrier liquid (he insists I use only tap water), = which the device uses in only minute quantities (3 or 4 drops). = Without any fancy equipment I once put my lips to the stopper side of = it and sucked to see if he was right, and indeed the device didn't = allow any of the water into my mouth. On the other side of it's = performance, the excess CO2 escape part, It works very well. I now = substitute the bubble counting present in some fermentation vigor = sounding instructions to airlock clicks. You see, the airlock works = this way (please bear with my rough ascii sketch): ( ) | | | (------) | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | \~|~|~~|~|~/ \ | | / \ | | / \| |/ | | | | | | | | There is a small unitank shaped cylinder (1,25" dia. x 2,5" tall) = that is intersected by a small diameter tube (0,30"dia x 3,5" long), = then there's the "movable part" (and only draw-back I see in this = design because If you're unmindful it can get lost), the inverted = midget test tube with a little more diameter than the intersecting = tube, that you insert in it and whose "lips" should always be in = contact with the barrier liquid (represented with tilde marks in the = sketch), and which acts by going up to let the gas bubble escape, = then down through simple gravity to close the airlock as soon as = pressure diminishes, emitting a distinctive clicking sound. The reason I represent this airlock here is that though I sincerely = doubt it comes originally from Gabriel's fervent mind, I have never = seen anything like this device in any homebrew supplies catalog (and = I've studied a few). I always see this look-alike plastic airlocks = that I have never purchased because I prefer glass over plastic = anytime for this application (try to wash a plastic airlock by simply = boiling it 15 minutes then to sanitize it by a 2 hour 250=AA regular = oven bake), then, compared to your regular "S" shape airlock, even as = it is a little more complicated to manufacture (Gabriel charged me = the same for making one or the other from scratch, a little less than = $6), it's almost half the height of the latter, thus saving you some = storage space.

Date: Sun, 26 Oct 1997 14:29:49 -0500 (EST) From: KennyEddy at aol.com Subject: Electric Brewing / Fermentation Chiller Chas asks about electrically heating water. He wants 5 gal to go to 190F in 20 minutes. A formula for figuring the power required to raise a certain amount of water to a certain temerpature is P = 150 * gal * (temp-rise) / minutes The 150 is actually a little higher than the "ideal" coefficient but this way it accounts for some inevitable heat loss (and is easier for me to remember!). Plugging in Chas' specs (assuming 70F starting) we get 4500W. On a 240V circuit this is around 19 amps. So a standard 240V 4500W element ought to work nicely (**WITH A GFCI BREAKER!!!**). This would require almost 40A on a 120V circuit, which is practically out of the question, unless two separate dedicated 20A circuits were used. This is the nice thing about splitting the 240V dryer circuit into two 120V circuits -- you get the 30A capacity, plus you can use $6 120V GFCI's installed in 50-cent boxes nailed to your brewery framework instead of having to install a $100 240V GFCI in your breaker panel (and pay an electrician on top of that). Note that when heating water, scorching due to high power density isn't an issue, as it would be in a mash tun or boiler. For those applications, one would want to spread the heat out over multiple elements; aim for less than 25W/sq-in as a no-scorch target. In my boiler, for example, I use two 240V / 4500W elements, each running off one 120V phase of the 240V line, which gives me 1125W on each element, but at a low enough PD to prevent scorching. Seems I remember that my PD is somewhere around 20 - 25 W/sq-in, and I have no trouble with scorching or caramelization. This arrangement, however, is not adequate for such rapid heating as Chas requests, but again, you can get away with high PD when heating plain water. ***** Matt asked whether I have any experience with / information on adding electromechanical refrigeration to my Fermentation Chiller design. Nope, not personally, but there are many possible approcahes to this. One way is to simply add a small "room" onto the front of a fridge. Remove the door and build an insulated box that can attach to the fridge. Basically an extension of the original fridge. Either the whole fridge can be temperature-controlled, or the box can have a thermostatically-controlled fan rationing the cold air, much like the Chiller. One could use a little cube fridge (~$100) as a cold source. Remove the door and you have a relatively compact source of enough cold air to keep one or two fermenters happy. I read here once where a guy was making "wine cellars" by actually carving away the plastic & metal shell of such a fridge, then building the remaining fridge "guts" into a cabinet and adding a thermostat. Great idea, and you don't have to mess with disconnecting and reconnecting the refrigeration circuit. You can duct the Chiller to a fridge or freezer; run one duct from the freezer to the Chiller and another from the Chiller back to the fridge to "conserve" cold air by recirculating it. The thermostat in the Chiller will take care of pulling cold air when needed. The Chiller can be reduced to a simple box, with the "IN" duct feeding the fan, while the open exhaust notch would feed the return duct. Such an arrangement can be added to a chest freezer in a similar way to adding taps -- build a wooden "collar" for the freezer between the box and the lid, and add holes to the collar for the ductwork. ***** See my web page (http://members.aol.com/kennyeddy) for ideas & related info on both of these topics.

Usually on Saturday I see that the package is pretty well swollen--a sign of activation. This Saturday, however, it didn't look like anything happened. So I decided that I better wait until Sunday. Sunday morning and afternoon passed and I notice that it still hasn't activated. I decided to toss the envelope and go get a new one from the local brewshop and try to brew sometime during the week. After some thought, I retrieved the envelope from the trash and decided I should see if the contents are salvagable in any respect. My only chance is HBD.ORG! Is the yeast in it worth salvaging? If anyone has a suggestion as to what I should do with the package please let me know. Thanks. Nick Return to table of contents
