---------------------------------------------------------------------- Date: Tue, 26 Apr 94 08:47:48 MST From: birkelan at adtaz.sps.mot.com (Joel Birkeland) Subject: Great Arizona Beer Festival Review The Great Arizona Beer Festival - A review I attended the Great Arizona Beer Festival last Saturday at Scottsdale Baseball Stadium. This is my review. I am not an expert beer judge, but I know what I like. The festival looked like a major improvement over last year's Beer Gulch Days. Moving to a more central location in Scottsdale certainly made it easier to attend. There were 23 different brewer's listed in the program, including Arizona brewers Hops!, Coyote Springs, Prescott Brewing Co., and Flagstaff Brewing Co., and out of state brewers Celis, Anchor, Tabernash, and Pacific Beach, to name a few. Some of the out of state brewers just sent kegs to be manned by the volunteers, who lacked knowledge of the product. The layout of the festival was unfortunate. All of the beer booths were crammed into two narrow corridors, which caused great difficulty because of the crowds. This made it difficult or impossible to get to all of the booths. I hope this problem does not occur next year. Attendence was very good. I arrived at 1:30 PM, 30 minutes after gates opened, to find the corridors jammed with crowds. I would guess that attendence was high enough to warrant a 2nd annual GAzBF next year. This is very encouraging. Now my own highly subjective review of the beers: Prescott Brewing Pale Ale: Oh boy, hop aroma! I am always looking for hop aroma, and I am usually disappointed by the average brewpub. These guys, however, have done it right, IMHO. Very tasty. Tabernash Wheat Beer: OK, another great beer. Spicy, dry, and with an aromatic nose. Although they are different styles, this beer has many of the features that I like in Celis White. Seems pretty near flawless, to my uneducated palate. Tabernash Denargo Lager: Nothing really wrong with this beer, it just didn't seem to do anything for me. Door County Brewery Cherry Rail: This is (i think) a light lager (?) with a strong cherry flavor and aroma, but, thankfully, no artificial red color. A good beer from a county famous for cherries and cold weather. Rockies Brewing Company Boulder Porter: 1992 GABF gold medal. They deserved it. Holy Cow Pale Ale: GABF gold medal winner? No noticeable hop aroma, not much hop character at all, to my taste. Perhaps I drank it out of sequence, having had the Liberty Ale earlier in the day. Pacific Beach Brewhouse Belgian Ale: I think that's what this was called. Full bodied and red, with pronounced ginger aroma and flavor. Good Stuff; they were out when I went back for more. Bandersnatch Milk Stout: Ah, so that's what they mean by extract tang: a nasty sour flavor right there in the middle of the taste. Yuk. These guys are clearly out of their league here. Celis Grand Cru: A fresh keg. Pierre Celis is God. Anchor Liberty Ale: A fresh keg. Fritz Maytag is God. Conclusion: Looks like we may finally get a beer culture going here in AZ. I hope that next year's event will have a better layout. Joel Birkeland Motorola SPS Return to table of contents
Date: Tue, 26 Apr 1994 11:54:07 EDT From: Jay Hersh <hersh at x.org> Subject: Re: The Oracle that Spake Hmm, Jack I've used Irish Moss for years, never a problem. Of course your problem seems to have nothing to do with the actual effectiveness of the stuff to attract out haze forming matter, but with your systems set up. This just seems to demonstrate inexperience with what Irish Moss is and how it works. You mentioned a mountain of crud, so I wonder how much you used. Instructions on the IM I purchase say 1/2 tsp 30 minutes prior to the end of the boil for 5 gallons. Since IM is just dried seaweed (Carageenan if I understand what I've read correctly) it does absorb moisture and it's subsequent volume is larger than when you add it. Your problems stem mostly from the nature of your system. Passing your post boil wort through siphon hoses, or fine mesh screens, tubes and/or pumps may not lend itself well to use of Irish Moss. Me I simply pour my wort through a strainer set into the oversize funnel I place on top of my carbouy. The IM does collect in the strainer but what colects is hardly a mountain of crud which makes me suspect you've used too much. While Irish Moss may not lend itself well to your technique I myself would not think a blanket denunciation is in order. To others out there wishing to use this you'd be wise to learn from Jack's mistakes. For Jack well you'll have to make the decision yourself if there are things you can do to modify your set up to alleviate the problems you experienced, or if you don't think the benfits of Irish Moss are worth doing so and you simply wish to use other clarifiers or none at all. That's one of the great things about brewing, there are so many right ways and what works in your kitchen for you may not suit me in mine... JaH Return to table of contents

I've had similar effects after a fast ferment. One thing that I have noticed about SNPA yeast (and I use it quite a bit) is that it's sensitive to cool/cold temperatures. It seems to want to drop out of suspension if things get the least bit cold. Could this have happened to your starter? If so then your shaking just got things started again. The foam on top of your flask could just be results of that interupted ferment. It's a good sign that there are no off smells but the best indication of the starter's health is a taste test. I've had some nasty smelling starters that tasted fine and made great beer. For IPA's and pale ales this is one of the best yeast strains around.

Wagnecz, X6616" <wagnecz at PICA.ARMY.MIL> Subject: Re: Composting Technology ( And Hops :-) A lasting and easy to make compost bin can be made from cinder blocks. There's two tricks involved: 1. Make it square and you can alternate the rows for interlocking effect. Ex: 1 st row: front: three blocks long ways in the middle with one width of the blocks on each side (ends) for a total of four blocks. The sides then are four blocks lengths and the back is the same as the front. Then alternate the side pattern with the front on the next higher level. (Try it, its easier to do than describe). 2. Turn the blocks in every other row 90 degrees so that the holes show (provides air flow). Grain composts real well when mixed with other stuff to lighten the mix. Use leaves, grass, coffee, anything organic (vegatable) that does not have grease, meat, or dairy content. The compost coming off this process is like rocket fuel for your plants!

I know that water can play a big part in all-grain brewing, but what about extracts? I have a brewed a great deal of extract-based recipes without adding gypsum (even though I have soft water). Am I missing something? What role does gypsum have in brewing better beer, if any? Thanks, Scott Return to table of contents

Date: 26 Apr 1994 08:18:18 U From: "Palmer.John" <palmer at ssdgwy.mdc.com> Subject: Saving Water, Lead-Free Brass In response to the question on how to conserve water while using an immersion wort chiller, my system seems to work pretty well. I use about 5 gallons to cool my wort. I dump it afterwards, but there is no reason it couldn't be used for watering. My immersion chiller is connected by plastic hoses to a garden pond type submersible re-circulating pump. The pump sits inside a rectangular cooler with ice and water. The warm return water from the chiller enters at the other end of the cooler away from the pump, where it melts the ice. The cooling water stays pretty cool this way. Here in Southern California, our tap water can be pretty warm. The pump is about the size of a six-pack. The water can probably be considered potable after chilling, as it stays entirely in clean tubing and the cooler while re-circulating. Takes about 20 minutes to bring it from boiling to 65-70F (20-25C). Make sure you get a high throughput pump. Many pumps will say 800 gallons per hour but when you read the small print it says that the value is at a zero height differential. Trying to get the little beggers to push water up a narrow hose to stove height takes a lot of steam out of them. Mine is one of the larger models, rated at 1200 gallons per hour (at zero height, 1 inch hose ID). It does an adequate job considering 3/8 inch hose and stove height. *** I am waiting for a FAX, but I talked with Nibco (valve company) of Elkhart, Indiana yesterday. They have begun producing a lead free brass line of valves. These valves are available in the 1/2, 3/4 and 1 inch sizes and are known as the Hydro-Pure brandname. They are stamped on the valve with HP, to identify them. In talking with an engineer at Nibco, he said that they were not widely available yet, due to lack of consumer demand. He said that hopefully they will be more so in the future, if the market moves that way (away from any lead containing alloys). I will talk with their Marketing guy on Friday or Monday and see about who or where it is available from. And I will post Part numbers when I get the FAX, but wanted to get this in tomorrows HBD.

For those who haven't seen one, it's a white plastic sphere with a tap mounted near the top of the sphere, and a mini-CO2 cartridge dispenser mounted in the screw top lid. I've been very happy with mine. The CO2 dispenser assembly is a metal fitting with two small thick rubber bands, one on either side of the lid. On one of my kegs, these bands are about ready to disintegrate. I went back to the store I bought them from, but found that the manufacturer in England is no longer in business. Does anyone know where I can find replacements? Cheers - Rob <rmorgan at cam.org> Return to table of contents
Date: Tue, 26 Apr 94 16:22:57 EDT From: Mark Stickler <mstickle at lvh.com> Subject: Sam Adams Triple Bock I was at a "Beers of Spring" dinner Sunday night which included Catamont Bock, Wild Goose Spring Wheat, Stoudt's Honey MaiBock, Dock Street's new Illuminator "Double Bock" (not really), Witkap Pater Abbey Single, St. Armand, Paulaner Salvator, and, as the "night cap", Sam Adams Triple Bock. Not being a big fan of such things as "Cranberry Lambic", I was very skeptical. Well, I have to admit it was a truely unique experience. If I had not been told this was a beer I would have thought for sure it was a port. I mean like an expensive vintage port! It did have more of a dry sherry aroma but the taste was port. It was supposedly 18% ABV achieved through the use of Pastuer Champagne Yeast. They expect it to be commercially available in the late summer in 6-8oz bottles at about $100.00 per 24 bottle case! It may not be that good but I would recommend trying one bottle if you can bring yourself to contributing to Koch & Cos. success. Like I said, I'm not a fan of "the Best Beer in America (TM)" marketing tactics, but I got to admit this was an interesting "beer?". Mark Stickler Lehigh Valley Hospital Return to table of contents
Date: Tue, 26 Apr 94 12:59:11 MST From: birkelan at adtaz.sps.mot.com (Joel Birkeland) Subject: Malty Aromas, Good and Bad Malty Aromas, Bad: I have encountered what I percieve to be a flavor defect present in several microbrewed beers that I have tried, and I wanted to find out if anyone else had encountered the same. For lack of a better expression, I have called it the "sack of wet horsefeed" aroma. It is a grainy smell that I would characterize as unpleasant rather than very offensive. I first encountered this aroma at the Beer Gulch Days in Pinnacle Peak, AZ last year, where it was present to some degree in all of the beer from the local brewpubs, with the exception of Hops! beers. This past winter I visited Dock Street in Philadelphia, and I could smell this in several of their beers. Strangely enough, I have never encountered this smell in bottled beer, nor have I smelled it in any of my homebrew. Do not confuse this smell with the very pleasant malty aromas associated with fine beers, e.g. the scent of Sierra Nevada Stout. The smell I am refering to is entirely different. This has bothered me for some time, especially since I have not seen it documented elsewhere. If anyone cares to enlighten me, I would appreciate it. Malty Aromas, Good: While I am on the subject, I would like to know how to get that GOOD malty aroma into my beer. I have brewed my last 10 or so batches all-grain, and I consider it to be very good beer (MHO), but the malty aroma has eluded me. I generally use 6-10 lbs 2 row, and 0.5-2 lbs crystal, black pat., and/or roasted barley as appropriate per batch. I kettle mash and generally infusion mash, with protein rests when necessary. Any suggestions on what would help increase the malt aroma? Thanks a lot, Joel Birkeland Return to table of contents
Date: Sat, 23 Apr 94 21:58:43 PDT From: Mark Garetz <mgaretz at hoptech.com> Subject: Adding bitterness, etc. Carlo Fusco asks about the best way to add bitterness to his under-bittered beer (in a post labeled "hop oils") First of all, you want alpha acids, not the hop oils. The hop oils are responsible for the hop aroma and hop character, but not bitterness. The easiest way to add bitterness to already brewed beer is to get some iso-alpha extract. These are alpha acids extracted from the hops that have been pre-isomerized. Add them at bottling (or even serving). Some products are calibrated in IBUs so you can figure out how many IBUs you want to add directly. Others are not calibrated, but for one batch you can add to taste to a small quantity of beer (say 6 ozs) and then scale up to the batch size. *** Someone else (sorry lost the name) asked about getting a little more hop aroma in his beer, stating that his current method of an addition shortly before the end of the boil wasn't cutting it, wondered if dry hopping with a small amount might do the trick, but didn't want as much aroma as SNPA (if I remember right). Sierra uses a generous charge of hops at knockout, with about a 20-30 minute steep (covered). You can try this with less hops, or just use more hops for your final addition. IMO, most brewers don't use enough, and when they don't get enough effect they are reluctant to use more hops. BTW, Sierra does not dry hop SNPA, but that might work for you if that's the effect you're after. Now that I think about it, you say you want more hop aroma (not hop character). I would try the dry hopping first, but this will also add a lot of hop flavor to your beer. The problem is that hop aroma is so hard to get and keep - it usually takes a lot of hops. Oxygen in the beer and headspace are the enemies of hop aroma, so you you might also pay close attention to your bottling technique and consider the new O2 absorbing caps. Use of hop oil might also do the trick for you (adds aroma without much contribution to hop character - IMO why most find hop oils "unnatural" in their effect). *** Jim Busch commented on my comment about 20-30 minute mashes at commercial breweries. Oops. I meant 20-30 minutes once they reached conversion temp (aka saccharification rest). I also was only thinking about the megas, not the micros. *** There has been a little discussion about specialty grains in the mash (or not). I sat in on the Advanced Homebrewing Course at UC Davis last Saturday, and in his "opening remarks" Dr. Lewis stated that Guinness is now brewed basically as a pale ale, and the darkness/roast flavor etc. is added after the beer is brewed, with the "dark liquor" somehow extracted from the grains in a separate process from the normal mash. I can only speculate that this gives them more room in the mash tun so they can increase output without needing a bigger tun. I can also report that UCD seems to have lost its "disdain" for homebrewers. It seems they have finally figured out where their future bread will be buttered (so to speak).

Date: 26 Apr 94 18:23:00 GMT From: korz at iepubj.att.com (Algis R Korzonas +1 708 979 8583) Subject: CO2 and watery eyes/crystal/mashing crystal/Davis crystal/Irish Moss Coyote writes: >before you dumped it? Have you ever SMELLED CO2 (not Co2, or C02)? >It will make your nose burn and eyes water. Trust me.... You know... CO2 *used* to burn my nose and make my eyes water, but I don't think it does any more. I'll have to try the old "1/2 cup of warm 7up" test and see, but I think years of judging have made me immune or something. Maybe it's just that I've been brewing and drinking and judging low-carbonation beers. ***** Then again later: >Carapils = Dextrine Caramel = Crystal. They are not the same cookie! Agreed that they are not the same, but are used similarly. Carapils is a very light crystal/caramel malt. The "Cara" in Carapils/Caravienne/ Caramunich stands for "Caramel." The way that all these crystal malts are made is that the germinated grain is raised into the saccharification range (148-158F) and allowed to "saccharify right in the husk" then, the malt is kilned (dried) at various temps (cool=carapils/dextrine/carastan, warmer=caravienne/crystal20/caramel20, hot=caramunich/crystal60/caramel60, veryhot=special B/crystal80,90,100,120,etc.) In contrast, pilsner/pale/vienna/munich/aromatic malts are made by kilning the germinated grain at various temperatures without the rest in the Saccharification range. Roasted grains, victory/biscuit/chocolate/black/ "roasted malt," are first kilned and then toasted at various temperatures. ************** Darren writes, quoting Bill: >>produced as the enzymes chop away (remember Charlie's picture of the little >>lumberjacks?). I can't see how the unfermentable sugars in crystal malt are >>immune to this enzymatic activity in the mash. > >If you are adding the crystal malt for the purpose of adding unfermentables to >the wort because a high final gravity is desired, I would think that you would >also be mashing at a high temperature. I believe, although I could be wrong, >that at high mash temperatures the main thing happening is that long starches >are being broken up into large sugars (both fermentable and unfermentable), but >relatively few unfermentable sugars are being broken down further. If this is >right, then it would seem that the large unfermentable sugars found in crystal >malts could survive the mash, or at least a large percentage of them anyway. Exactly. This issue came up about three years ago or so. I researched it as best I could and certainly found lots on info on the enzymes, but could not find what the sugar composition of crystal malts were. I subsequently tracked down an email address for George Fix and asked him about it (and invited him to join HBD). To summarize our discussion, yes, if you mash the pale/pils and the crystal malts together at the low end of the saccharification temps (148F end) the beta-amylase, working together with the alpha-amylase, will convert much of the unfermentables in the crystal to fermentables. If you mash the whole lot at the high end of the range (158F end) the beta-amylase will be denatured quite quickly and only alpha-amylase will be active. What George said he does is that he uses crystal malts for their flavor and regulates fermentability with mash temperatures. It would be equally correct (but different) to not mash the crystal malts, which indeed would give you more unfermentables, but you have to note whether you mashed the crystal or not so you can repeat the recipe. >Also on the topic of whether or not to mash crystal malts, the article called >"The Influences of Raw Materials on the Production of All-Grain Beers" by Gary >Bauer in the 1985 All-Grain Special issue of Zymurgy, Gary states that crystal >malt still has some starch left in it and it should be mashed. Perhaps poorly made crystal malts have significant starch in them, but modern, high-quality crystal malts have very little. Also, it's another reason to not allow the temperature of the steeping crystal malt to rise above 170F (to minimize the gelatinization/liberation of what unconverted starch is present). ****** Jim writes: >Often, the trub that rises to the top after day one is removed to reduce >particulate matter that can lead to astringency problems. The use of open >fermenters provides an easy method for the observation and skimming >requirements of top fermented ales. A related note (and possibly a plus for the blowoff method) is that some brewers bubble air through the freshly cast out wort to bring the trub to the top of the vessel and then remove it from the top. I read this in J.S.Hough's "The Biotechnology of Malting and Brewing" while looking for the saturation point of oxygen in wort. ********* Jeremy writes: >I had a long correspondance about this topic with a student at Davis. After >numerous false starts at an explanation he came up with the "fact" that >the barley used to make crystal malt has more alpha 1-6 linkages, which >are immune to the amylase action in the mash.

The effect should be the same if you made this barley >into pale malt and mashed it with the low alpha 1-6 pale malt. I'm quite certain that this is *not* true, for example, I know that Crisp Malting in the UK used to use the same, prize-winning Maris Otter barley for making both pale ale and crystal malts. The answer as to why you need to make it into crystal malt is for the unique flavor of crystal malt. I've never read anything firsthand from Dr. Michael Lewis or any others from UC Davis, but if the second-hand info I've read is what they really said, then I think it's time they did a reality check. ******* Sean writes: 5) Irish Moss Gelose or Carrageenan - A texture modifying agent used in a great variety of processed foods, including canned poultry, light beer, salad dressings, cottage cheese, canned vegetables and meat products. Included among the reported effects are ulcers, colon cancer and colotis. In the processed foods, the Irish Moss is actually eaten. In beer, it settles to the bottom of the kettle and is left behind. If any does actually get into the fermenter, it would certainly not make it to the bottle -- fear not. Al. Return to table of contents

The question was, if you were to subscribe to one, which one would you choose? I got 6 responses, summarized (paraphrased below) 1. go to a brew supply store and look through issues and see for yourself 2. 4 responses essentially saying they preferred BT for the technical aspects and thought that Zymurgy was for a new brewer type ie, less technical, more recipes and general how to clarify, aspects of hops, recipes, gadgets etc, some said that best of both worlds is to get both. 3. Response from Al Korz. quoted below: Original-From: iepubj!korz (Algis R Korzonas +1 708 979 8583) Subject: BT vs Z You will no doubt get a bunch of email saying that Zymurgy has been riddled with mistakes over the years, however, these people will also not be aware of the changes to the editorial staff beginning with the next issue. I can personally assure you that Zymurgy will be as good as or better than Brewing Techniques in terms of the accuracy of the information, starting with the next issue. That said, let me compare the content of the two magazines. Brewing Techniques has had a history of leaning their articles towards the technical side. There has been, and is sure to be, lots of practical information for intermediate, advanced and professional brewers. Zymurgy, on the other hand, has had a history of targeting beginners to intermediate brewers, but has recently, tried to include more advanced information also. Zymurgy also includes a bit more information "surrounding" the homebrewing hobby with sections on homebrew clubs, homebrew supply stores, competitions, BJCP exams, etc. Personally, I would not give up either of my subscriptions since I get loads of information from both magazines, but if pressed, I think I would have to keep the Zymurgy subscription whereas the Brewing Techniques is more like high-tech icing on the homebrew cake. Al. (CHP again) Thanks to all who responded, especially Algis for the details. If anyone has anything to add, or more comments about new Zymurgy....please post or email me at the address above.

They smelled great before they went into the brew but I've yet to taste them in the finished product. These hops are organically grown - no pesticides, herbicides, or synthetic fertilizers. Does anyone know what the regulations are for pesticide use on hops (ie, what chemicals are allowed? what application rates? do hops have different regs than other foods?) Or, for the residual amounts of these chemicals allowed to remain on hops sold to consumers? What health risk do we as homebrewers face, isolated or cumulative, by using non-organically grown hops? What are the environmental consequences of using particular pesticides and herbicides in growing hops? Thanks! All answers/comments are appreciated. David Huffman ---- "Who'll stop the rain?"

Gros) Subject: kajun kookers I was at Costco the other day (warehouse type store) and they have their summer/picnic type stuff out. In addition to both rectangular and cylindrical coolers, they had a propane cooker. The one I saw was the kind with the legs placing the burner about three feet off the ground. I have one of these (different brand though) and like the pot being up higher. According to the instructions, they'll support about 75 pounds: enough for a five gallon batch, but not a ten. The cooker at costco was either $55 or $60. They generally have empty 20# propane tanks for $16 also. - Bryan Return to table of contents

Webb <rbw1271 at appenine.ca.boeing.com> Subject: Wort Chillers when water shortages are a problem Brett Shorten, of that world brewing center Toowoomba, Qld, Australia (in the words of Michael Jackson, 'where?') Asks about the use of water for cooling the wort in a land where there's hardly any water to begin with. Water use should be on everyone's mind, no matter what their location, or how long the drought. (The tour guide for the Great Western malting plant in Vancouver, WA told us that the plant uses 10 *MILLION* gallons of water a day. Beer making is a water intensive hobby...) As a Xmas gag gift, I took 10 ft. of copper tubing and made a baby immersion chiller, complete with fittings. Big fun. Ha, Ha. Later, I was thinking about how such a thing could actually be made useful. I made another one, this time without the hose fittings. Instead, I used regular hose clamps and some plastic tubing that just fit around the copper. I stick this pre-cooler into a bucket of ice water, effectively cooling the water even further before it cools the wort. I have no data on 'how much I've saved', but for very little effort, and little cost, I shorten the time and water used to cool my beer somewhat. As the saying goes, your milage may vary, but it's worth a shot... I also use the hot water that initially comes out of the cooler to clean the equipment that can be cleaned, such as the mash/lauter tun (I use a 48 qt. cooler), the high temp PVC pipe that I use to strain with, various spoons, etc... If I have any (hot or warm) water left, I wash my car... Or I water the garden. I try not to waste the water or the heat that I've invested so much effort into. Have a lager on me...

Michalski, MD" <michalski_jm at rophys.wustl.edu> Subject: MO laws/AB ads Yesterday rickh at gcctech.com asked about homebrew laws in various states. It remains illegal to homebrew in Missouri. There are two forces that maintain this barrier (three if count apathy). One is the powerful conservative lobby in this state (we couldn't buy any ETOH beverages on Sunday until recently) and the second is the legal stronghold that the St. Louis megabrewery has on the state legislature! It took a long legal battle against AB just to allow Brewpubs to operate in Missouri. As I was driving home from work yesterday I heard a radio commercial for Bud Light. A homebrewer was talking with his wife. It seems he had decided to make beer and put it into Bud Light bottles (who would ever do that ;). His big mistake was in trying to pass this handcrafted product off as an AB product to his friends. Even a priest (according to his wife) found the "swill" undrinkable. Is AB becoming so paranoid that no one will find their products satisfying that they have to stoop to such a low level as to take swipes at homebrewers? I don't think any homebrewer in his right mind would try to pass his superior home brewed beer off as an insipid bud. JEFF M. MICHALSKI michalski_jm at rophys.wustl.edu Return to table of contents

I would also be _very_ interested in finding out the effects of higher temps on the characteristics imparted to beer (I've checked the yeast FAQ to no avail) i.e. what yeasts can tolerate higer temps with/without adverse affects on flavor, or interesting effects (esters, etc...) I will say that Pike Place Ale yeast seems to handle higher temps (75-80) quite well, and apparently the yeast will not do its job at temps below 66 deg.. Red Star seems (IME) to impart a nasty flavor to beer at +75 deg (described as 'extracty tasting) in all grain beers.. anyone else have similar results?

Date: Wed, 27 Apr 1994 20:29:44 +1000 (EST) From: allison shorten <shorten at zeus.usq.edu.au> Subject: Thanks for chiller advice Thanks for all who responded to my query for methods of chilling wort when water conservation is a priority. I certainly had a much larger volume of replies (22) than for any other question I have asked on this forum. Obviously either the subject of wort chillers or water conservation (probably mainly the latter) really get HBDers going! At any rate, it is great to get such a lot of helpful responses. In case anyone is interested, I will briefly summarize the main suggestions. 1. Use a water pump or similar and recirculate the water through an ice bath. 2. Go for a counterflow chiller - they are inherently more efficient in terms of water required. 3. Use about 4 sanitized 2lt PET bottles (labels and black ends removed) full of ice, which when placed in the wort chill it at about the same rate as an immersion chiller 4. Use the water again, such as for washing clothes or watering the lawn (this is what I personally do, as in town here water restrictions are not as important). 5. Route the used water back to the tank it is drawn from (this is not practical in my friend's case, as it is a long way from the house, but in general it seems a valid point).

[...] This intrigued me because in my counterflow setup I use less than 5 gallons of water to cool a 5-gallon batch, and more than 5 gallons of water to sanitize and clean up. I've thought about saving water but the chiller isn't the major use. Do other people's CF chillers use significantly more than 3-4 gallons of water to cool a batch? What am I missing? I typically have 45F water at the tap and chill to 80F wort in about 10-15 minutes. - --- David Deaven deaven at ishmael.ameslab.gov A504 Physics tel 515-294-6878 Ames Laboratory fax 515-294-0689 Ames IA 50011 Return to table of contents

I've used it twice so far (I haven't tried the second batch yet) but the first batch tastes great, but leaves a kind of dull listless feeling the next morning. In addition, there is a pretty bad taste in the mouth as well. I've experienced the bad morning mouth before, but I attributed it to certain varieties of hops. This time I used the tried and true Fuggle / Goldings combo and get the "icks" in the morning. So now I'm attributing it to one of the "higher" alcohols. Whatcha think? too high a ferment temp? Probably in the mid to upper 60s. I know its just not me, as three other people reported the next day, that they just couldn't get moving. Mash was 1 hour at 152, SG1.060 FG 1.010 Irish moss has been in the Digest as of late. I asked the question before and got no response.
