" According to the folks at Merchant Du Vin, importers of this fine beer-- the clear bottles were a marketing choice. They feel that the foil band around the neck and the tall sides of the 6 pack holders prevent the light from affecting the beer. Some mention of the fact that the beer itself is very dark would also help reduce skunking was made. [ I find that idea preposterous] Note: These comments are as best as I can remember a personal phone conversation of about one year ago. I asked the same question Adam asked. - ------ Best Brewing, Alan Talman Karp's Homebrew Shop <http://www.homebrewshop.com> 2 Larkfield Road East Northport, NY 11731 Phone : 516-261-1235 Fax : 516-261-1573 Return to table of contents
Date: Fri, 10 Apr 1998 23:03:36 -0600 (CST) From: Stephen Cavan <cavanst at duke.usask.ca> Subject: Phil's Counter Pressure filler Someone asked recently about the counter pressure filler made by Listermann, the Phil's series. I tried one Friday night and have two comments. Although I have never used a counter pressure filler before, and was expecting a complex procedure, it was very easy to use. I could almost work the unit with one hand. The single valve idea seems good to me. The directions were clear, and it took me maybe 10 minutes to connect the hoses and keg disconnects. The only problem I had concerned the type of bottle I could fill. I had prepared some 2 litre soda bottles, but the rubber bung on the filler was too small. I then grabbed some regular PET beer bottles (12oz size), and again the rubber bung was too small for the bottle opening. Finally I was able to use my Grolsch style bottles, and I was lucky to have a few cases of them. On the whole, I am really happy with the filler. Cheers, Steve Return to table of contents
Date: Fri, 10 Apr 1998 22:02:23 -0700 From: "Layne and Katrise" <wetpetz at oberon.ark.com> Subject: Belgian Wit Spices David Rinker writes in HBD #2623 on Belgian wit; >5)There has always been reported to be a 3rd spice in both Celis and Hoegaarden, one which no one can identify (Jackson speculated once that it might be cumin)--might want to experiment here too. Experimenting is the key here.... I recently bought a copy of "The Brewmasters Bible", The Gold Standard for Home Brewers by Steven Snyder, 1997. Within are several good looking recipes for Wit beers or White Beers in this style. I though it was interesting to note some of the spices that are used in these beers, of course they included the orange, coriander that is a must have I think. Cumin was not one of the spices added to this collection of recipes but cardamom and chamomile was. There seems to be a really big variation of the amounts of spices used in a batch as well as the timing of spice additions. They range from 1/4 oz. at 30 minutes or 60 minutes for example, to 1 ounce steeped and then again in the secondary. I would say that a lot of experimentation is needed if we want to get the right profile for our OWN tastes. Just my two cents. I've used spices in beers a few times now and I think that the timing of spice additions is almost as important as which spices to use. There is no sense adding a spice if you don't add it at the right time because you might not even know it is there! Orange does benefit from a boil, (although short, 5-10 minutes?). Freshly crushed Coriander does not need to be boiled at all as it is very aromatic. If the spice you are using has a powerful aroma and flavor don't boil. If you can hardly smell it then chances are that boiling will bring out the flavors. This is the rule-of-thumb I've used and I get good results. (Just getting close to my expectations is a good result for me.) I recently helped out a friend with a Vanilla-Almond Porter and we tried it for the first time yesterday. The recipe was changed many times in the interim on the amounts and timing of the spices used because there is so much variance and so many opinions on how they flavor the brew in the numerous methods that are used. Finally my friend decided to go with his gut instinct and I think that he couldn't have made a better beer. Although we both agreed that it would be interesting to try changing things around to see the effects it would have on the recipe. The beer was awesome by the way. It had orange and lemon zest in the boil, vanilla beans were steeped, vanilla and almond extracts were used at bottling. There was oats in the mash with 2-row and roasted malts. The beer was smooth, creamy and full of blended flavors.

This should be easy for Al K, Jethro, George, etc... For some reason, I have a glut of spiced ale. I have a 3 gal keg, and several 1/2 gal bottles with carbonators attached. ( I needed the 5 gal keg it was originally in.) All of this beer has been in the fridge for some time, but I want to put one of my other kegs in to drink. Can I remove the keg from the fridge for a week or three, without causing off flavors? Relax, Have a Homebrew, but keep an eye on your legislators! Paul Haaf Somewhere in the Pinelands of So.

My girlfriend and I are heading to Lancaster, UK in the middle of July (she's going to present at an academic conference, and I am going to tag along) and I am wondering if any UK'ers or well travelled others may have some recommendations for "gotta see" beer-related sites in that area. We also plan a day trip just into Scotland so any recommendation for that area would be appreciated. Thanks, Dan Cole Roanoke, VA Return to table of contents
Date: Sat, 11 Apr 1998 08:26:32 -0400 From: Mark Tumarkin <tumarkin at mindspring.com> Subject: fermentap - other uses Tony writes: >Hi , I'v been thinking about purchasing a product called Fermentap, it >holds a fermenting carboy in a inverted postion and is supposed to >facilitate Yeast harvesting and allows you to transfer wort without a >siphon. I would appreciate anyones comments on this product. Well, I won one of these devices at a homebrew club raffle. I had previously thought about buying one, so I was very pleased. However, after using it a few times I was not as pleased. It does work but I quess not up to my expectations. One of the ovbious attractions is the idea of harvesting and/or removing yeast. It just doesn't work as well as I'd hoped. Maybe oneday I'll have one of those beautiful stainless of copper cylindro-conical fermenters that shine so prettily in the brewery of my dreams. However, I came up with one alternative use of part of the device. It comes with a base to hold your inverted carboy. This base consists of a large ring at the bottom, and a smaller ring at the top - separated and held by steel rods. I use this base to hold my inverted carboy as it drip/air drys after cleaning with sanitising solution. This works great, the carboy opening is down, reducing fears of any nasties settling into it as it dries. And it is held securely, reducing fears of breakage. You could, of course, make a similar device, much less expensively, by cutting a hole of appropriate size into a small piece of plywood and setting this over a box, plastic milk crate, or some other base to make a stand. Works great. Mark Tumarkin G-ville, FL Return to table of contents
Date: Sat, 11 Apr 1998 11:27:15 EDT From: KennyEddy <KennyEddy at aol.com> Subject: Big Brew Big BW / Extract Wit AlK wrote concerning Barleywine yeast for the Big Brew: "I have had very good experiences with the Danstar Nottingham and Windsor yeasts. The Nottingham is slightly more attenuative. The Windsor slightly more sulphury during fermentation and is a little more "tart." If I do go with dry yeast, I'll probably go with the Nottingham. However, what I will probably do is brew a 5-gallon batch of Special Bitter from liquid yeast the week before the BIG BREW. I will bring unpitched wort back home from the event and then, after racking the Bitter off to a keg, split the dregs between the Barleywine wort carboys." I made a BW last November and did almost exactly this, except I used the Nottingham dry yeast for the small-beer "starter" batch (an Amber Ale). Fermentation of the BW was much like any other in onset and duration. My BW went from 1.092 to 1.017 without additional Champagne yeast. The BW already tastes pretty good so I would agree that the Nottingham is a fine choice for this baby -- plus it allows you to pitch big without hassling with a starter (use at least two packets and follow the rehydration procedure on the packet...see http://www.lallemand.com for more info). ***** Kit Anderson had an interesting idea for brewing an extract Wit: "I was having an off list discussion about an extract based wit. "Impossible", says I. "Nobody make unmalted wheat extract." Then a little voice said, "King Arthur does." Egads! Plain old white flour. Of course! Has anyone tried adding wheat flour to the kettle? I'm thinking 50% extra light DME, 50% wheat extract and 1/4 cup (or more?) of flour." Clever thought, but I wonder if it's really what you want. Raw (unmalted at least) wheat is used in Wit recipes but don't forget that it is *mashed* with other grains (pilsner malt), so its starch is largely converted to sugar. Adding flour to your recipe will result in starch haze and will be a potential source of infection (bottles that go kaboom). So why not use wheat malt? Supposedly there's a flavor difference between malted and unmalted wheat; besides, it ain't "right". But so what. I think using wheat *malt* extract would make a perfectly acceptable extract wit. Use your 50-50 recipe above, or look for "weissen extract" containing somewhere near 50/50 wheat and pilsner malt, and use that for 100% of your fermentables. Once you're there, the rest is easy and I guarantee the result will be witty enough. Save the flour for bread. BTW see the excellent extract refernce web page at http://triton.cms.udel.edu/~oliver/firststate/tips/maltextract.html for a good look at the composition of many extracts. Seems most "wheat extract" is still ~60/40 wheat/barley. Ireks' Weizenbier is stated to be 100% wheat malt; Munton & Fison comes in closest to 50/50 at 55% wheat. ***** Ken Schwartz El Paso, TX KennyEddy at aol.com http://members.aol.com/kennyeddy Return to table of contents
Date: Sat, 11 Apr 1998 11:38:11 -0400 From: "Michael J.Maag" <maagm at rica.net> Subject: Planispiral chiller data point I needed a chiller so I checked the HBD archives and decided on a planispiral design (like an electric stove burner). I used 3/8 in. soft copper, which was mostly in a spiral flat coil already. I used a 14 inch long piece of 1/2 in. copper pipe to secure the coil to using stripped 12 gauge wire. I used 28 ft of the 3/8 in. soft copper. The design worked better than I hoped for. I suspend the thing in the brew pot for the last 15 min of the boil to sanitize. It took only 15 min to cool 5 gals of boiling wort to 70 degrees using tapwater!! I was impressed. The thing was placed flat about one inch below the surface of the wort. The temperature gradients created a flow which piled the hops in the center of the pot as bonus, and there was no need to move the chiller around to make it effective. Needless to say, I had great cold break. 8*) Mike Maag, Chilling out in the middle of the Shenandoah Valley. Return to table of contents
Date: Sat, 11 Apr 1998 14:25:03 -0400 (EDT) From: <eaweston at email.unc.edu> Subject: FWH As another data point, I would like to concur with Al Ks observation that FWH is especially (if not solely) beneficial to hop *flavor*. I just reviewed my tasting notes for those batches of mine which received FWHing--all (except for those which received dry hopping too) had a pronounced hop flavor. Furthermore, those which were hopped solely w/ FWH (or had only kettle hops added) had little to no perceptible hop aroma--this included my first FWH beer, a Bavarian Wheat which ended up with waaaayyyy too much Saaz in the finish (way out of spec for the style but amazing none the less--I used only 1oz of hops in this 6gal batch! ) Regards, David Rinker Return to table of contents

Date: Sat, 11 Apr 1998 19:10:03 -0500 From: "Jim Hodge" <jdhodge at worldnet.att.net> Subject: Gott vs. Igloo coolers, Part II Oops! It would appear that Gott and Igloo cooler innards are both made of polyethylene, but Igloos use low density polyethylene and Gotts use the more temperature resistant high density polyethylene. I've used a Gott cooler for two years now and while there is some buckling in the liner when it gets hot it is not enough to interfere with my mechanical stirrer or the false bottom I have in. I suspect an LDPE liner would not fare nearly so well. Sorry for spreading any misinformation. Jim Hodge Return to table of contents

Date: Sun, 12 Apr 1998 00:59:04 -0400 From: "Christopher Tkach" <tkach at tiac.net> Subject: Re: CO2 gas detectors With the recent discussion on CO2, and its apparent harm to individuals, I thought that I would chime in... Ok, I may get slammed for this, but I believe that CO2 is not harmful to a human directly, afterall it's in the air we all breath, along with other gases. What you should be worried about is the amount of oxygen (O2) in the air, which (last time I checked) is what is required for us to live. Back in my limited career as a geo-environmental engineer, I took a HAZMAT class, and in that class we used an instrument that measured the amount of oxygen in the air...too high a level and an alarm would sound (explosive danger), too low a level and an alarm would sound (suffocation). It was meant for entering confined spaces. I think, but don't quote me on this, that the average amount of O2 in air should be around 13-17%, the rest is mainly nitrogen (N2), with other gases taking up about 1%. So, the real danger with CO2 is if its increase in concentration is effecting the concentration of O2 in the air. I know it sounds a bit confusing, but I'm sure some others on the hbd could explain it a bit better than I did. - Chris Newmarket, NH Return to table of contents

Date: Sat, 11 Apr 1998 22:29:27 -0700 From: John_E_Schnupp at amat.com Subject: starters/wort aeration/yeast I've some questions and thoughts on starters/wort aeration/yeast. When people talk about pitching a one quart starter, do they mean that they have one quart of yeast slurry? Or does that include the spent starter wort? My most recent starter was approx. 900 ml of starter wort, 1 Wyeast smack pack and continuous stirring while pumping filtered air into the headspace in the flask. I pitched the whole works into a 5 gallon batch. The fermentation seemed to start faster than with starters made previously using an airlock on the flask. The batch of beer had quite an active fermentation. I noticed quite a bit of "stuff" in the blow-off jug. It looked and smelled like yeast and since I used an ale yeast, top fermenting, I assume it is indeed yeast. Can this yeast be harvested or re-pitched? As far a aerating wort, I recently built something that I will test the next batch. I had an old grill/fireplace lighter that got broken. The tip where the butane came out was brass and the opening was pinhole sized. Hmm, I drilled a hole in the end of my copper tube that goes from the boil pot to the carboy and soldered the tip in place. I have some 1/8"OD (1/16"ID) tubing that fit nicely onto the small brass tip. Used a hose barb adapter to join to my filtered aquarium pump. Dry run with water worked great. Using something like this I'd think it would be better to pitch the yeast first, so that they can get down to business using that freshly aerated wort sooner, correct?

Date: Sun, 12 Apr 1998 01:31:09 -0500 From: "Rob Moline" <brewer at ames.net> Subject: Big Brew Questions Big Brew Questions.. I have received a number of questions about the brew, the selection of malts, hops, etc.... The question of discrepancies between the recipe that Brian Rezac posted and the one I posted....I am sure that this is the result of mistakes made by myself in transcribing the info to the AHA. I know that Brian has posted that he had my permission to 'genericize' the recipe. This was done in order to ensure that all homebrewers would have access to similar ingredients, no matter what malts were in stock at their local HB shop. That is, it was an 'inclusionary' device to promote access to as many brewers as possible. One of the details of the original brew. As a self described 'seat of the pant's' brewer, I cranked out the original recipe on a sheet of paper, and quite frankly my hop rate wasn't even adjusted for gravity, just based on the amount of malts involved, and my knowledge of the LABCO system's past perfomance with other brews....and current style guidelines.... I then made a call to Steve Zimmerman, my first assistant brewer at LABCO, who had left the job for the simple reason that he was unable to support his family on 8K$ per year, the max salary paid for his position. Yup, dedication goes a long way, but the final straw for him was when the GM, who had promised me a certain wage for an assistant prior to hiring Steve, and subsequently re-affirmed to me that said level of income, (.25 cents per hour more) would be on the next paycheck, reneged on that commitment. I believe the terms were, as told to Steve directly, "What makes you think you are worth 25 cents more an hour?" Who could blame him when he left after about 6 months? Not I. But Steve was always more technical than I in his approach to brewing, so I called him with my proposed recipe, and over the course of the next few hours and phone calls, suggested a few changes. Some were used, some not. He also crunched the hop rate, and advised the results as presented by the "Brewer's Calculator" program. I decided that I wanted to be dead in the middle of the range for BW's, which at that time were 20-50 IBU's, so 35 was the target. That I attempted a BW was based on the fact that it was the last brew of the year that we had re-opened the LABCO, so I wanted to finish up with a bang. The large proportion of Caramel 30 was due to an ordering error by my malt distributor...(I got my Schreier/DWC and Briess products from Kraft Foodservices, now known as Alliant), and this attempt offered an opportunity to burn up a lot of excess inventory. The inclusion of 50 lbs DWC Pale Ale malt was the result of another mistake on my part.....on the morning of the brew, being short of the 700 lbs 2Row, (as I had sold a bag to a homebrewer, and failed to note this on the inventory), the DWC PA seemed to be the next best thing. Oh, yeah, one more thing, while I knew that I had a decent brew, when all was said and done...it would never have been entered in the World Beer Cup, nor the GABF, if not for the insistence of a few folks, like Mark Silva, Curt Schroeder, and Andy Walsh and the members of the Northern Suburbs Brewers of Sydney, who all had a taste of the brew before it achieved recognition, and in the case of the Sydney brewers, even returned score sheets! Silva, in particular, was adamant that I enter it, and the first to make me think that perhaps I had something worthy here. Success with a Silver at WB Cup ensured entry at GABF. If not for the advice of these folks, and others, I would have never held back the few kegs that later gained success....and believe me, when dealing with a big beer like this, months of aging are your friends..... This just reinforces my long held belief that most brewers are 'too close' to their brews to really know what they have, and what they don't have....that is they can't always recognize the flaws in their brews, especially those that creep in incrementally. It should also reinforce what I have already stated, and what has been s tated to me by many other medal winning brewers about their own brews .........."I was lucky." And as a final note on this subject, if it had not been for for years of trying to catch up and figure out what you guys on the HBD were talking about............and if not for the patience of the many who have aided me directly, (and not laughed too hard at my lack of savvy), and for the countless that never knew they aided me, for I would never reveal to them that I was still trying to understand what they were saying....there would be no current event using my brew........ The fact that the inaugural Big Brew has chosen to use any recipe of mine is a testament to the fact that the HBD is a powerful resource for educating brewers....you have been the genesis, inspiration and ongoing encouragement to 2 Bronze Medals at WB Champs, 4 Silvers at WB Champs, 1 Gold at WB Champs, a Silver at WB Cup, and a Gold at GABF...all within a 12 month period. Compound that with a 99/100 rating on the original Big 12 from James Robertson's panel for the "Beer Taster's Log," and even the lurkers out there may believe me when I say that the HBD does train brewers........ It also doesn't escape me that I would have never gained a scholarship to Siebel without the bedrock of training that you folks have given.... Thanks to you, the HBD.... I do hope that many of you will brew this beer and enjoy it as much as I have....and more than that, see it as a testament to the combined energies and intellect of the talent that lies within our community....

Date: Sun, 12 Apr 1998 09:26:02 -0400 From: "David R. Burley" <Dave_Burley at compuserve.com> Subject: Chlorine Dioxide Brewsters: Jim Liddil says about Dave Miller's recent faux pas in BT: >Can any of the people who know water chemistry discuss the letter in the >lastest BT about aeration of water, calcium carbonate precipitation and >chlorine dioxide? This is obviously a screwup ( BT editors where ARE you?) since chlorine dioxide has nothing to do with bubbling air into boiling water to strip CO2 during the removal of calcium ion by boiling. In that letter, substitute "carbon" for "chlorine" so it reads "carbon dioxide" and the letter makes sense. I suspect that Dave, relying on others for any chemistry, as he admits, didn't spot his obvious error in this piece. Later in this issue of BT he does have a legitimate discussion of chlorine dioxide as a sanitizer, as I recall. The point in the letter is that the bubbles of air pick up carbon dioxide gas released by the higher temperature. This carbon dioxide is available since the calcium carbonate/bicarbonate equilibrium is shifted towards carbonate at the higher temperature, releasing CO2 into the water. The air strips out the CO2 and carries it out of the vessel being boiled. This allows the calcium carbonate which is less soluble than the calcium bicarbonate to precipitate and the calcium ion content of the water is reduced if the water is decanted off the precipitate. Use of additions of calcium salts like calcium sulfate to precipitate more calcium carbonate through "common ion effect", just won't work unless the added calcium salt is more soluble than the carbonate. In this case, the sulfate solubility is about 2 grams/liter and the carbonate is 0.015 g/l, so this method is effective. Also the sulfate is 20% less soluble at boiling temperatures than at room temperature and the calcium ion content is further reduced. Additions of calcium chloride ( which is faster to get into solution) would work fine in which the calcium would be precipitated as the carbonate and the chloride is left in the solution. Alternatively the use of sulfuric acid would form calcium carbonate, calcium sulfate and carbonic acid which would be released during the boil as CO2. All these methods are effective and are used, depending on the water analysis and the beer type as it regards the remaining ions in the water. Miller gives an excellent example of the effective use of air purging in removal of large quantities of calcium carbonate by boiling based on his own experience in a brewery. I suspect this technique is much more useful when used with large volumes of water and perhaps not even needed by the home brewer who boils his water in five gallon batches. I would be interested to hear reports on the effectiveness of calcium removal by boiling with and without air injection on small kettles. I can't do it because my water is softened before it goes into my RO unit which I use for brewing.

My beers seem to get heavier, if anything, over time in the keg. Funny, my beers all get lighter. When I first keg a batch, it weighs about 45 lb.

Do it correctly and you will get good results. So you are saying that your opinion is the correct way, and all else is wrong. I use hop bags for all my additions, including 15 FWHed brews. Works great for me. I get excellent results. Of course that is just MY opinion. Do you have some numbers to prove that hops are not utilized properly when placed in a bag?

Date: Sun, 12 Apr 1998 16:31:29 -0400 From: Fred Johnson <FLJohnson at worldnet.att.net> Subject: Big 12 Barleywine I will be participating in the Big Brew '98 and read with intense interest Rob Moline's original notes on the Big 12 Barleywine, from which the recipe for the Big Brew was taken. I was flabbergasted (look that one up) when I read the 35 IBUs in Rob's original recipe. This was the target and the outcome from the Siebel analysis. I immediately ran to my calculator (designed with the homebrewer in mind) and came up with 100 IBUs. I ran it again using a strict Tinseth model and came up with 77. These values would be even higher if one were to correct for utilization of pellets being higher than for whole leaf hops (which I naively assumed). How is it that the utilization was SO low for a 7 bbl (217 gallon?) batch? Or am I missing something here? The Big Brew '98 recipe calls for 63 IBUs, still a far cry from the 35 in Rob's original recipe. When I put the Big Brew recipe into my calculator I get 104 IBUs (because the hopping rate appears to be scaled down almost exactly from 217 gallons to 5 gallons. Again using Tinseth's formulas I get 81 IBUs. How about an explanation Rob? - -- Fred L. Johnson Apex, North Carolina Return to table of contents

Big changes at Hoegarden though.. It will be brewed in Canada in the not too distant future if not already. ............ We just returned to the states and since our belgian beer sense was fairly fresh we bought several of the examples of the belgian beers we know here in the US. .... the results were really quite shocking... the biggest disappointment was Rodenbach which had become our beer control while traveling over there... it had oxidized everyway imaginable and had none of the fresh bright character we have come to know. (This was perhaps the first Rodenbach I have dumped) .........my overall impressions of the belgian beers over there as opposed to those imported here is a sense of freshness/brightness at the source... . Some of the stronger beers (like Chimay) seem to age well even over here, but the lower gravity beers seem to suffer from poor handling. we recently opend an '87 saison de papaix from vapeur... twas fabulous.... when we stopped to visit Jean Lois we sampled the same beer recently made... it was also excellent (different beer though). The Lambics/Krieks seem to survive the rough handling just fine as do the wits. ___________________________________________ JIM WALLACE ... jwallace at crocker.com http://www.crocker.com/~jwallace ___________________________________________ Return to table of contents

This one threw me for a loop at first too until I realized that the references to chlorine dioxide were obviously typos and that carbon dioxide was clearly what was meant. Other than that I agree with Miller's corrected explanation of the mechanism with a couple of minor exceptions one of which has to do with the necessity of aeration. Aeration should not be necessary if the water boils. Any gas with very low partial pressure of carbon dioxide will serve to scrub out the CO2 released by the overall reaction: Ca++ +2HCO3- --> CO2 + H2O + CaCO3 The steam formed by the boil should serve to do this as well as air or nitrogen or whatever. However if steam is not available sparging with another gas is necessary to purge the CO2 and move the equilibrium in the above equation towards the right. Return to table of contents

I am not planning on doing this, but am trying to help out another brewer. My first suggestion, which he will be using, was to mash 2 lbs pils and 2 lbs unmalted wheat. Then I thought of the flour thing. A lot of folks were concerned with making wort gravy. This can lead to stuck spigots and such. Some mentioned infection problems from residual starch. The haze in a wit is from protein and the starch needs to be converted. One person came up with the recipe out of the Belgian Classic style book. Silk Lady uses 2.5 lbs whole wheat flour sifted into the grains in a partial mash of 1.5 lbs pale and 1 lb wheat malt. 90 min at 150F. Iodine test and mashout at 170. Then boiled with 2 lbs pale DME and 2 lbs wheat syrup. This sounds like the most effective way to acheive the results. It will still lack the flavor of a full mash using 50% unmalted wheat. - -- Kit Anderson ICQ# 2242257 Bath, Maine kitridge at bigfoot.com got beer? Return to table of contents

It's a Kelvinator Mod# TPK190SN2W.... I have a couple of concerns and since there a couple of refrigeration brewers out there, I thought I would seek advise. First, in the winter months the freezer does not freeze. Second, it seems to "turn on" too often in these warmer days. It appears that the thermostat is exposed to exterior temps. Does anyone have a clue as to where the thermostat would be exposed to outside the fridge? Am I off? Is it something else? Any ideas where I might be able to find a schematic? I've tried to contact the company via email without success. Private mail is great. TIA. p.s. I constructed the Poor Man's Counter Pressure bottle filler described in Ken Schwartz's web site... I wanted to publicly thank Ken for providing such helpful and "thrifty" information for the cause.... Thanks again Ken!!!
