Get used to it, because there is a great deal of hear-say which gets retransmitted in brewing circles (yes, including this one, though admittedly it's got a lot less than most). I back up my answer with every batch of beer I've made in the last 2 years in my 17 US gallon Alu pot.

Date: Thu, 20 May 1999 08:45:09 -0400 From: David Rinker <David_Rinker at med.unc.edu> Subject: Siebel-tech question I submitted a version of this question about a year ago to the HBD, and would love to have yet another brewer's input. Here it is in a more-concise form :) It regards recipe scaling in genereal, and also the proportional adjustment of specialty grains. 1) Can extraction rates (pts/lb/gal) for base malts be extrapolated linearly when the amount of grain involved increases significantly (like doubling or tripling a 5-gal recipe)? I have read that larger mashes are generally more-efficient than smaller ones even when water to grist ratios are kept constant. 2) If I'm trying to double a recipe how should I adjust the specialty grains? For example, if I double the pale malt in my brown ale, can I simply double the chocolate malt and expect the flavor profile of the larger batch to be the same as that of the smaller batch?

Bottle-conditioning vs CP filling Hello all, A quick question for the Siebel folks: do you have any hard data on the shelf life of bottle conditioned versus counter-pressure filled beers? Are the bottle-conditioned more likely to live through heat/agitation (like shipping to a summer competition) than CP? Thanks in advance for any help. Thanks also to Rob for setting up this unique opportunity. Paul Shick Basement brewing in Cleveland Hts OH Return to table of contents
Date: Thu, 20 May 1999 09:43:00 -0400 From: Eric.Fouch at steelcase.com Subject: Siebel Questions HBD- OK. Fred is hog tied and ball gagged in the back (from last nights bachelor party), so he won't offend or embarrass The Siebel crew or the HBD. Some questions for the Seibel masters, pulled form old HBD's: >From September 1998: HBD- I have not received any response to my query of the possibility of "FWH" effects from spent hops from a previous batch: FWH a barleywine, and after the boil, dump those hops into the second brews' boil. Will any FWH characteristics carry over? Could it be that I'm the first homebrewer to do this? What are the copyright and marketing implications of divulging new brewing techniques to an electronic forum? But seriously, folks- has anyone done this before, or thought about it? Seems to me, the low temps of sparging fix the aroma components (as I understand it). The first boil won't extract them all. Could they be extracted in the second boil? I also queried a while back about the possibilities of "First Wort Spicing"- adding spices (such as coriander) to the first runnings. Different chemistry, but could their be a similar effect? Especially if you "FWS", and FWH concurrently? I have tried this with a Wit- FWH with .5 oz Cascades (out of style, I know) and FWS with 1 Tbs crushed coriander. It's still in the secondary. >From February 1998: HBD- I haven't been able to find any information on Wyeast 3942, Belgian Wheat. What are the characteristics of this yeast? Does it like to use ferulic acid? Should it be treated like German wheat yeasts, or is it not really a clove or estery developing yeast strain? Todays fresh question- I spiced a wit with 3gm each of coriander, cardomom, lemon peel and lemon grass. After 15 days in the primary, when I bottled, I got what I first thought was autolysis. Upon further review, it is definately a spicey character: It smells kind of rubbery, and meaty in the aroma, but tastes OK. Not great, but not how it smells (thankfully). I know overuse of or using old coriander can cause this. Does the same apply to cardomom? I got it from a bin at the bulk food store, don't know how old it is. Did I use too much?

It brings to mind a discovery I made a couple of weeks ago after three years of brewing (and capping). It seems that the ubiquitous two handle, bright red, capper has reversable jaws that allow it to grip the much wider neck of a champagne bottle. Just when you think you know it all....

One flavor aspect I have not yet been able to produce is a malt flavor in my Bavarian style lagers. I do know the difference between malty, sweet, and caramely (is this a word?). I think what most homebrewers refer to as malty is really caramely (from crystal malts) or sweet. If this flavor is confusing then you need to eat some chocolate malt balls to get an idea of what the malt flavor is that I am talking about ("he said balls, ha ha ha"). Anyway, how can I achieve this malt flavor that I often taste in imported German lagers? I have tried the usual techniques to achieve malt flavor with no success: 1) Yeast Strain: I have used the common Wyeast strains Munich Lager, Bavarian Lager, and Czech Lager. 2) Using imported German Munich malt as the base malt, and adding Melanoidin malt. 3) Decoction mashing and pressure cooking. 4) Extended lagering. Is a malty flavor in my German lagers unachievable at the homebrewing level, is this even too difficult for Dr. Pivo or Fred Garvin? Please help! Kyle Bakersfield, CA>> Return to table of contents

Kenton" <jkenton at iastate.edu> Subject: Siebel Qs Thanks, Rob for reminding me to ask these questions: On sparge water, is there a quantifiable advantage to acidifying the sparge water? Also, what temp should I try to maintain in the grain bed while running-off? On maltiness, what are some tips for homebrewers (making an initial foray into a malty style, like double bock) to get good malty flavors. I also want to keep the IBUs respectable (within style). Thanks Jeff Jeff Kenton If you can't be nice, at least have the decency to be vague. Return to table of contents
Date: Thu, 20 May 1999 09:00:37 -0500 From: Pvrozanski at ra.rockwell.com Subject: Re: Keg Carbonation You failed to say what style of beer you are planning to force carbonate but your 12psi at 42-44F could be a little low for most beer styles. There are definite volumes of carbonation you want to aim for depending on style. You can find the table that shows the correct psi depending upon temperature to achieve the desired volume of Co2. The method you describe of just letting the keg sit will work. However it takes about 2 weeks for the Co2 to be absorbed into the beer. The resulting carbonation is acceptable. Shaking the keg is faster although from what I've heard the bubbles are large, kind of like soda pop. Not exactly what you want in beer. I use a sintered stainless steel stone, called oddly enough "The Stone", to force carbonate. It gives probably the finest carbonation and works over night. The stone is a little pricy, around $25, but I find that it does the best and most reliable job. Return to table of contents
Date: Thu, 20 May 1999 10:04:27 -0400 (EDT) From: Paul Shick <SHICK at JCVAXA.jcu.edu> Subject: Re: malty tasting lagers Hello all, Kyle from Bakersfield CA asks about getting the elusive "German malty taste" in his lagers, having tried most of the suggested approaches. Kyle, maybe the problem you're having is with your technique. I've noticed that my beers always end up with a stronger malt profile when I run off from the mash tun quickly and sparge fairly minimally. This isn't quite as extreme as the no-sparge approach, but I think that it uses the same principle and avoids the tannins that mask the malty flavor you're after. It does involve adding 10-15% more grist to the grain bill, but that's a small price to pay. The only real downside is that this lowers your apparent efficiency dramatically, and you can't take part in the "I got 97% efficiency this batch" debates.

Date: Thu, 20 May 1999 09:33:16 -0400 From: Jeff Renner <nerenner at umich.edu> Subject: Re: Sankey Kegs jslusher <jslusher at flash.net> asks about kegging in Sankeys, and especially about cleaning them. I just posted this a month ago or so, but since traffic is low, I'll repost. I find this easy enough to do that I haven't looked into CIP as Jon Sandlin asks about. I like to be able to see inside. I've been kegging in Sankeys about 18 years. First, *release all pressure* by pressing down on the ball valve or you'll get your teeth full of a heavy valve and draw tube assembly when you release it. Hold a rag over it or you will get a face full of stale beer. Then, using a small screwdriver, pry out the flat retaining ring. Next, using the jaws of a pair of pliers as a tool, turn the valve to the left maybe 30 degrees, and lift it out. It takes less time to do it than to describe it. Soak the inside with bleach water for a few hours and boil the valve/drawtube to sanitize it. Rinse, fill with beer, reverse the above steps, The hard part is re-installing the flat retaining ring. You have to press down to compress th O-ring (which is under the valve). To do this, I put a plumbing part called a reducing coupler (I think 3/4" to 1/2")) on top of the valve, hook a board under the lip of the keg top, across the coupler as a fulcrum, and sit on the other end. Then I force the ring into its slot by twisting a wide screwdriver blade in the gap against the coupler until it's home. It takes me about 30 seconds. You'll need to get a tap, of course. I keg about half of my beers in these, the rest in 5 gallon Cornelius (soda) canisters, which have the advantage of being easier to fill and seal, using cheaper taps, and taking up less room in the fridge. Of course, they hold less. Jeff -=-=-=-=- Jeff Renner in Ann Arbor, Michigan USA, c/o nerenner at umich.edu "One never knows, do one?" Fats Waller, American Musician, 1904-1943.

Date: Thu, 20 May 1999 11:36:22 -0400 (EDT) From: mcnallyg at gam83.npt.nuwc.navy.mil (Jeff) Subject: Siebel question: diacetyl flavor blindness Hi All (and especially the folks from Siebel), Ever since I first started brewing, I have been trying to learn to recognize the various aromas and flavors in beer. To make a long story much shorter, I have pretty much convinced myself that I am unable to detect diacetyl in beer (no, I do not wish to revive the recent thread on whether it is desirable or not). My homebrew club organized a doctored beer session last week using the guidelines in "Evaluating Beer" by Charley Papazian. During this session we doctored Miller Genuine Draft with various substances to train ourselves to be able to recognize common beer flavors and aromas. For the diacetyl spiking we used the artificial butter flavoring found in grocery stores (McCormack brand I think). At the various levels suggested in the book, I was unable to detect diacetyl in either the aroma or flavor. Only after adding *way* more of the artificial butter flavoring was I able to detect it in the aroma. I never really detected it in the flavor, although at the much higher level I did note an increase in sweetness and mouthfeel. Is there anything I can do about this apparent blindness to diacetyl aroma and flavor? Might my fairly severe allergies (and related sinus problems) have anything to do with this problem detecting diacetyl? Note that I did'nt really have any problems with any other substances besides diacetyl. Hoppy brewing, Jeff ========================================================================== Geoffrey A.

Date: Thu, 20 May 1999 10:52:47 -0500 From: "Ernst, Joe" <joee at gasullivan.com> Subject: Newbie Step Mash Questions Hello Collective, I've been asked by my father in law to make this American Premium Pilsner from Cats Meow. This will be my 3rd all-grain beer, but my first with a stepped mash. My lauter/sparge tun is a SS brewpot with a false bottom, my heat source is an outdoor propane cooker. The comments within the recipe are not mine, but those of the recipe's author. > Ingredients: > 6 lbs Lager malt (I use 2-row, but 6-row is appropriate for the amount of adjuncts) > 1 lb Mild ale malt > 1 lb Rice > 1/2 lb Flaked barley > 1 lb Flaked maize > 4 oz Malto-dextrin powder > > Nottingham Ale yeast (dry -- I know, I NEVER use dry yeast...) or Wyeast #2112 California Lager (optional) > > Procedure: > Boil rice for 30 minutes and add grains and water for mash -- > First rest at 94F for 30 minutes to help breakdown the adjuncts -- > Raise temp to 122F for 30 minutes for protein degradation -- > Raise temp to 140F for 15 minutes for better head retention and clarity -- > Raise temp to 153F for 45 minutes for starch conversion -- > Raise temp to 158F for 20 minutes for complete conversion -- > Mashout at 168F for 10 minutes -- Sparge w/168F water at < 6 pH -- I have several questions regarding mash procedure: How much water should be boiled with the rice, and how much, if any, of that water should be figured in as part of the strike water volume? How do I calculate strike water volume and temp to hit the first 94F rest? I will be combining 210-212F rice/water with 8.5 lbs grain at 70F. At each step, should I infuse boiling water to step up the temp or apply direct heat? If I should infuse, do I hold back some of the initial strike water for this purpose, or should I add more water at each step? Finally, any comments on the appropriateness or necessity or purpose of the rests and times are appreciated! Thank you!

Others tend >to put the keg in the fridge, hook normal dispense pressure up to it, and >forget about it. >Although I'm sure both provide adequate carbonation, I'd tend to side with >the latter camp. As convenience goes, it beats the hell out of shaking a >full corny, and as far as consistency of carbonation, it seems to be the >most reliable alternative. I tend to prefer the former, shaking with a low temp (35F) only requires a few minutes at 30 PSIG, this is no real problem for me. With my fridge setup, I normally do not leave pressure on the kegs at all times, I pressure up to 10-12 PSIG, then serve beer until I have noticeably low flow, then connect and run up again to 10-12 PSIG. The reason I do this is: * I just do not trust the keg seals, hose seals, etc. for not leaking, and one can loose one's CO2 easily over a week or so if not careful. * I do not have an easy way to run the hose into the fridge, without drilling holes for passage. I do not like to put the gas cylinder in the fridge because of space limitations, moisture condensation, and temp variations all involved with this method. >if higher-psi shaking is the way to go, how do you get >the keg to back itself down to my expected 12 psi dispense pressure without >venting the keg and creating a foamy mess? One can vent the keg without creating a foamy mess, just do it with the gas in valve. I just depress for a few seconds until I HEAR 12 PSIG. :>)) >Lastly, for those of you who have tried both, which in your opinion gives >the best foam retention (or is there a difference at all) ??

Date: Thu, 20 May 1999 11:31:08 -0400 From: joytbrew at halifax.com (Joy Hansen) Subject: Bottling Imperial Stout From: Matt Birchfield <peridot at usit.net> "A few questions about bottling my Imperial Stout ... 1-How long should it ferment in the secondary; Should it be aged in bulk or in bottles? (Brewed it on May 1st and racked to secondary May 8th when vigorous fermentation subsided)" My experience: There isn't a specific time in the secondary. It can stay there as long as you need. I've had brew at this alcohol level in the secondary for several months. "2-How much sugar should I use for carbonation, and will I need extra yeast when priming?" My experience: IMHO, high alcohol brews require much higher carbonation levels than do low alcohol brews. I don't know the specific volumes; however, I up the sugar to at least one cup / 5 gallons provided that the yeast pitched with it can handle the alcohol content. If not, just force carbonate the brew. Most likely not to style; however, I love a thick creamy head on these strong brews. Hard to make; however, that's the way I like them. "3-At what temperatures should it be conditioned and stored, and how long should conditioning take?" My experience is that 2 weeks to a month is necessary for these high gravity brews stored at summer room temperatures. If it doesn't have substantial carbonation after two week, you can be that Mr.. Murphy has his hand in the brew. Keep this brew around for an extended period before consuming to let the complexity and smoothness develop. "This batch's OG was 1.092, and is my first attempt at anything over 1.065, so any help will be greatly appreciated." As long as the final gravity get down to 15 or so, I think you'll be OK. What type of yeast did you use and what is it's alcohol tolerance? 9.5% to 10.5% is a real kick in the pants and is much more stable than lager type brews. Personally, I like to brew barley wines, strong Scotch ales, strong Belgian ales, and imperial stouts, leaving the lesser brews to Bud and Miller! Of course, there's a lot to be said for Samuel Adams Summer Ale. And Celis White . . . Joy"T"Brew Return to table of contents
Date: Thu, 20 May 1999 12:02:49 -0400 From: joytbrew at halifax.com (Joy Hansen) Subject: Cleaning Sanke type fermenters Jonathan Sandlin wrote: "I plan to start doing my primary, seconadary and serving in 1/2 barrel sanke kegs. I am curious if it is possible to clean and sanitize without taking the keg apart. I plan to fill the keg through the tap with P.B.W and let sit over night. After that, I will empty the keg with CO2 pressure and then add Star San the same way. Will this work? I hate taking the kegs apart, and I can ferment in them by letting the gas escape through the out hose of the tap. Any criticisms or ideas would be greatly appreciated." Hi Jon, I think I posted a remedy for your use of the sanke as a fermenter. Maybe not as it may have gone private. Anyway, I don't think it's practical to try CIP of an unopened sanke used as a fermenter. I assume that you plan to use a sanke tap to release gas pressure during fermentation. I have strong feeling that you shouldn't limit your gas escape to a single exit. You may exceed the pressure limits of the sanke if the tap becomes clogged. The commercial cleaning systems are only intended to remove stale brew, not brewing gunk! I recommend removing the siphon tube and installing a rubber stopper type blowoff tube (at least 1 inch clear PVC). This arrangement is difficult at best to get a seal. The seal isn't essential; however, I use the blow off bubble rate to monitor the rate and completion of fermentation. I found that cleaning a fermenter is difficult and that the brushing required to be sure all the gunk is removed is nearly impossible through the sanke opening. I opted to remove the sanke opening and install a corny lid in its place. I drilled and cut the original fitting out, shaped the final opening to fit the corny lid, hammered the top of the sanke as smooth as possible yet fit as close as possible to the corny lid. Then, I use a William's Brewing corny closure "O" ring. This "O" ring is larger in diameter and soft so it conforms to the many imperfections of the fabricated opening in the sanke. I leave the safety release in the corny lid and then drill a hole about 1 inch in diameter to accept a blow off tube. This approach requires a nitride tipped drill bit, a bimetal fine tooth saber saw, and a high speed rotary file (in an electric drill or a LARGE dremel). An anvil that can be slipped into the opening for hammering the opening flat is critical. It takes a lot of fiddling; however, it's an inexpensive and workable means of fermenting in a half barrel sanke. Cleaning is easy since I can use hot PBW and a little elbow by reaching inside the keg to clean the gunk. Sanitation is accomplished with Star San. The lid and "O" ring is soaked in Star San until time for closure and the keg is allowed to drain for some time before use. For run off into the keg from the brew kettle through the chiller, I use paper towels which have been soaked in Star San to help keep the floaty vermin out of the fermenter. I'm learning TIG and silver solder technique and I may attempt to fix a large portion of the corny top to the sanke top. Return to table of contents

Given a slightly basic water source of say 7.2-7.5, is it common practice to acidify sparge water? Might this allow a higher sparge temperature, better extraction, and/or less astringency? The bottom line is, of course, will it make a better beer? Thank you Guy Burgess Return to table of contents

Date: Thu, 20 May 1999 15:11:59 EDT From: BillSiebel at aol.com Subject: Views on the future of Craft Brewing... Rob Moline has posted a wide open question to me: "How do you view the upcoming viability of the CraftBrewing segment in the US? Any projections for the next 5-10 years for 1) micros...and 2) brewpubs?" Craftbrewing has gone through a great growth period in what has been a very stagnant decade for the brewing industry as a whole. But I think the next ten years will see consolidation in the Craft segment while, at the same time, we will see growth come back to brewing in general. Demographic changes are a leading factor in this turnaround. During the last decade many baby boomers moved into their 40's and early 50's. As people age they tend to drink less than they did in their 20's (though I try to keep up my share). So this trend, along with increased health consciousness and social awareness of drinking and driving, caused the per capita consumption in this country to drop enough to counter the general growth in the total population. But this year is a turning point. The baby boomers are not going to cut back much more on their drinking and, more importantly, their children are approaching the legal drinking age. This year we are bottoming out on the number of 21-26 year olds... about 20.8 million in all. But by the year 2011 the total is expected to rise to 25.2 million, more than a 20% increase. The past models have anticipated that this would result in an average annual growth in beer volume to be 1.5% through 2010. This may not sound like much, but with the miracle of compound growth, this would indicate a growth of just over 40 million barrels per year in that time period to a total annual volume approaching 230 million barrels. However the better news is that the old models have been underestimating beer sales in the last three or so years, enough so that Robert S. Weinberg, noted industry economist, has prepared a new model that now expects growth to total about 54 million barrels before 2010. All right so far but what does that mean for Craft Brewing? Craft Brewing has flattened out in the last two years. But it is more of a consolidation. A number of good breweries are growing at a great rate. Others are losing business and going out of business. Craft breweries as a whole are doing about 5.6 million barrels of business, about 3% of the market. But this segment is just a part of the "high priced beer" segment that also includes imports. Imported beers have, and still are, growing at a rate of about 15% per year and their volumes now total 16.5 million barrels... about three times the size of Craft Beers. Of course the larger brands are supported by a lot of advertising which many craft brewers can't afford. But what is good news is not only that the overall beer market is going to grow, but it is expected that the high priced segment will also grow from about 12% of the market to about 18% of the market. So with market growth and segment growth the volume of high priced beers is expected to go from about 22 million barrels in 1998 to about 47 million barrels by 2010. So there is room for everyone who makes a good, consistent beer to share in this growth. I'll take the second part of Rob's question first. Brewpubs. There are over 900 of them now producing just over 700,000 barrels of beer. There is no reason that if a brewpub is in a decent location and runs a good restaurant with good food and service that they should not do well. There is also no reason that any well run restaurant that sells a fair amount of beer could not also support its own brewery. So there is no reason that good restauranteurs and brewers working together, with proper financing, should not be able to open many more brewpubs. I don't know what an upper limit would be, that depends on the number of entrepreneurs who make good plans and decide to move forward on them. But, for the sake of argument, lets say that the number of pubs more than triples to 3,000 or so. At that level I would expect them to produce 2.0-2.5 million barrels of beer. These pubs would actually be more in competition with other restaurants than with other breweries, especially non-pub packaging breweries. And this many pubs would not be taking any business away from packaging breweries, large or small. I would guess that half the beer they sell would not be sold if the pub were not there. The customers would be at another restaurant or at home and might have a Coke or wine or other type of drink. And I believe the other half of beer they sell does not take away from the rest of the market either. For those who go to pubs gain a greater appreciation for beer and interest in beer. For each beer they drink at a pub they likely buy more at the store to take home. Therefore I see a good future for pubs, so long as they run a good restaurant with good food and service in a good location. Packaging microbreweries are another story. They compete in a wider market that, as of a year or two ago, has supply catching up to and surpassing demand. There are over 400 packaging microbreweries out there but only about 80 over 5,000 barrels per year and maybe about 20 over 30,000 barrels per year. I believe in the future it will be hard for breweries under 20-30,000 barrels to be competitive enough to survive in the long run. And being a fourth generation Siebel at the Siebel Institute, by long run I mean to survive an intergenerational change. Now let's look back at the expected size of the high priced beer segment in 2010: 47 million barrels. Imports won't go away and the large domestic brewers will also make beers for this segment. The total market segment is expected to do slightly better that double. Let's say that Craft Beers do better than the market and more than triple to 18 million barrels. Of this you have at least 2 million barrels from pubs. Then the top five Craft Brewers will likely have another 3 million barrels. This leaves another 13 million barrels for everyone else. If you buy my assumption that it will be hard for those under 30,000 barrels to compete in the long run, and go with my assumption that most Craft Brewers will find a happy home under 100,000 barrels, then the average size of these brewers will be about 65,000 barrels per year. Divide that into 13,000,000 and you get 200, plus the five large ones, and that gives you a total of 205 packaging craft brewers being the long range sustainable number using this analysis. And right now the total is more than 400. This is not to say that new ones cannot enter and succeed. It will just be harder. This is also not to say that a few cannot survive at smaller levels of production. But it is less likely. Craft Brewing should be alive and well in the future but the face will change somewhat. It will be the more professional brewer that will survive in the competitive field of packaging and retail sales. And the good restauranteurs will be able to do quite well with an ever larger number of pubs. But they all will need beer loving customers... go do your share!

I have been searching the web, but have been unable to find anything other than references to a old Zymergy article. I would like to find a web version if possible. Thanks for all replies to my previous questions about my RIMS design and a Corona clone. The Corona clone was not a joke, I do like the flavor of a cold Corona, however without the lime. After the many responses about how they intentionally skunk their beer, I am not so sure I wish to make any. Thanks again Doug Brown - -- -------------------------------------------------------- / J.

Date: Thu, 20 May 1999 11:34:27 -0700 From: "Peter Zien" <PZ.JDZINC at worldnet.att.net> Subject: Counterflow chiller sanitation Jerry, Cleaning and sanitizing a counterflow chiller is a bit trickier than an immersion chiller, and a lot more important since your beer actually flows through the coils. Here's the regiment that I employ: 1) Prior to brew day, set up the brew kettle and racking cane to run through the wort chiller. I use a hose clamp on the wort chiller's outflow hose. Then fill the kettle with 5 gallons of warm water and either PBW or One-Step (others may work well also; I've tried these two). 2) Start the siphon, drawing sanitiation solution through the racking cane and wort chiller. When the solution is flowing from the wort chiller, clamp it off for 15 minutes. Then resume the flow of solution. When you feel the warmer water once again coming out of the wort chiller, clamp it off for an additional 15 minutes. 3) Repeat holding the solution in the coils as often as necessary. 4) On brew day (and with my water heater raised to "C", very hot), I run hot water through the wort chiller for 15 minutes prior to use. 5) After use, immediately rinse the wort chiller with cool, and then hot, water for 10 minutes. Cover exposed inlet and outlet ports with aluminum foil. After every 5 or so batches, I also run diluted white vinegar through the wort chiller prior to running the PBW or One Step through. Although One Step claims to not need rinsing, I can't get myself to trust their claim! For a good way to see how "clean" you're brewing, try covering your hydrometer sample and see how long it takes to spontaneously ferment. You need to use a sanitized hydrometer and sample jar, and take care to keep it covered with Saran Wrap to prevent the airborne yeast from invading. If your hydrometer sample begins fermenting after a day or two, you're not brewing "clean" enough. Good luck! Peter Zien Return to table of contents

Spivy" <baspivy at softdisk.com> Subject: Wort Chiller Efficiency vs. Pump Speed "Perle" wrote: I cannot pump through my counter flow wort chiller directly from the boiler to the fermenter. The wort will come out at about 90 -95 degrees. It seems what you really need is colder water running through the "jacket". I have just completed a counterflow chiller based on fitting I got from The Beerslayer and tested it. It works great for normal fall / winter / most of spring tap water temperaturs, but in the hot Louisiana summers the water table heats up considerably. I have (after testing with boing water and a Testo precision thermometer) decided to add a three coil, 1" OD, copper "pre-cooler". hose goes from the tap into the sink (where the coil is laying under an opened bag of ice), then to the chiller jacket, through the jacket to the outlet hose which leads back to the sink to the drain. Do you think this would work for your situation? Brett Return to table of contents
Date: Thu, 20 May 1999 15:48:27 -0400 From: "Houseman, David L" <David.Houseman at unisys.com> Subject: counterflow chiller sanitization I've been using my counter flow chiller for 3 years without a problem (knock on wood). While I'm mashing (or boiling) I bring 5 gallons of water to a boil and run that boiling water through the CFC in the reverse direction that I put hot wort through. I retain the water and then when I'm finished using the CFC, I bring that water back to a boil (it's usually still pretty warm so I'm saving some $$) and run that again through the CFC. This results in storing a rinsed and sanitized chiller. Once a year I put PBW solution in the chiller, then rinse it out, to get rid of any deposits on the walls. To keep the CFC sanitary inside, I bought two solid rubber stoppers (hardware store) and put a hole 1/2 way through each that was just big enough that they can be used as end caps for the 1/4" copper tubing of my CFC. I boil these with the water each time I boil water to put through the CFC and then place them on the ends to keep anything from getting into the line. Return to table of contents
