Two were made by straightening the tubing and pushing the inner tubing in, then wrapping the assembly around a 15" form. The third (actually the first attempt) was made by leaving the tubing in the original form (larger than 15" dia for the larger tubing) and forcing the inner tubing inside it. Then it was wrapped around the 15" form to reduce the diameter. I don't know which one I have. The final CFC has a 15" inner diameter. There are about five and a half turns for my chiller. I doubt I have kinked it by turning it on a 15" dia form. ===== Steven, -75 XLCH- Ironhead Nano-Brewery http://thegimp.8k.com Johnson City, TN [422.7, 169.2] Rennerian "There is no such thing as gravity, the earth sucks."

I love them for making a cheap plastic fermentor into something quite a bit more sanitary and secure. For about $7, you permanently snap on a gasketed ring, which has large threads that you screw the lid into. Online survivalist stores ("Head for the hills! The Feds are coming! Or maybe the Messiah!") sell them for holding grain. Jeremy Hansen Return to table of contents
Date: Tue, 21 Dec 2004 08:14:29 +0100 From: "Fredrik" <carlsbergerensis at hotmail.com> Subject: Lag times vs viability To contribute to the lagtime/starter discussion the came up, FWIW, here are some of my experienced lag datapoints... ( I define apparent lag as the first significant(ie not fluctuations) CO2 release, either airlock bubbling or pressure buildup in a capped bottle ) 1) My normal lag time when pitching into the wort/beer is 6-8 hours for ales. Then I prepare the yeast, do all aeration etc prior to pitching at low temp, so that most of the adaptation phase is all done before pitching. 2) The only times when my lag is more than 12 hours, I have been using old dry yeast, or otherwise crappy or not well prepared yeast. 3) The worst I've seen in a beer batch was more than 24 hour lag, but then I used one old pack of outdated nottingham. Not activated, just rehydrated.When there was no activity at 24 h I pitched more (good) yeast and it took off. In starters... 4) I made a ~5 million/ml/P(estimate only) starter out of the openend 19 month old (unsmacked!) smack pack WY2565 and I say ~48 hour lag, and it hit peak after around 60+ hours. As mention in the other post the methyelene staining indicated 86% viability (wich I do not trust). 5) I made a ~0.5 million/ml/P(estimate only) starter out of a frozen WY3787 (frozen at -20C for 6.5 months in glycerin/water) and as per the methylene staining it was now ~12% viable. Starter lag was 48 hour, full peak hit at 60 hours. Smells good at revival too. I have revived this yeast two times, the last time was at 5 months, then pitching rate was 1 million/ml/P and the performance was identical, ~48h-lag/60h-peak. Give or take some hours. My shortest lag ever were 2-4 hours in low gravity batch fermented at room temp with lots of active prepared yeast. My loose impression so far is that unprepared or dormant seem to have an intrinsic lag that may be up to at least 12 hours or maybe more? This is my impression based on the lag offset wether you prepare or not prepare the yeast for a given pitching rate. I have noticed that if the yeast is prepare there doesn't seem to be a reason for having lags longer than 12 hours or something like that (maybe even more), that said perhaps it makes no difference to the beer but anyway. /Fredrik Return to table of contents
Date: Tue, 21 Dec 2004 07:09:06 -0500 From: Fred Johnson <FLJohnson at portbridge.com> Subject: Grain Storage Containers I thought I should add my one bad experience storing bulk grain in plastic buckets. I used to put grain into a lidded plastic buckets in the tall crawl space of my house in the winter. The temperature was always cool or cold. However, mice find this area to be a nice shelter, especially in cold weather, and they can smell the grain. Mice have no problem chewing through plastic buckets. I think they actually enjoyed the conquest of getting to my grain. I now put 55 lb sacks of grain in metal garbage cans in the crawl space. (I leave the grain in the sack for easy removal of the last of the grain as it nears the bottom.) Fred L Johnson Apex, North Carolina, USA Return to table of contents

I store specialty grains in vacuum bags and/or sealed 1 gallon buckets, but I routinely store pilsner and pale malts in their original sacks for 6-9 months at a time. Do I really need to invest $100 to buy two of those vittles vaults just to store grain? It seems to me that each individual grain comes with its own hard case to protect it :-) ===== Ed Jones - Columbus, Ohio U.S.A - [163.8, 159.4] [B, D] Rennerian "When I was sufficiently recovered to be permitted to take nourishment, I felt the most extraordinary desire for a glass of Guinness...I am confident that it contributed more than anything else to my recovery." - written by a wounded officer after Battle of Waterloo, 1815 Return to table of contents
Date: Tue, 21 Dec 2004 09:25:57 -0600 From: blutick at juno.com Subject: Re: Celis White Clone? Randy Mosher wrote about his conversations with Pierre Celis on brewing Celis White: >I think Celis used a lactic culture of some kind, but he was very secretive >about this aspect. I toured the Celis Brewery with a group of my fellow North Texas Home Brewers back in August of 2000. This was sometime after Miller Brewing had bought the Celis family's remaining stake in the business and taken complete control of the brewery. Lenzie Kinyon was the Celis brew master at that time and served as our tour guide. It was a great tour and Lenzie answered our questions on Celis' ingredients and brewing procedures. He held back a bit when we asked about their yeast strains, saying they were proprietary. Other than that, he answered our questions in a very straightforward manner. When I asked how they got the acidic bite in the White and the Grand Cru, Lenzie told me that they added glacial acetic acid prior to bottling. As for spices, he told us that bitter orange peel and coriander were used in both the White and Grand Cru. They had samples of both coriander and bitter orange peel for visitors to examine in the hospitality room. Lenzie never mentioned chamomile, but I never asked about it. It's possible, of course, that Miller changed some ingredients and procedures after they took control of Celis. Maybe so but I couldn't detect any difference in the beers. If Pierre Celis did indeed use acetic acid, I can understand his desire to keep that a secret. Sharing that information could only lessen the mystique his beers enjoyed at the time and might even hurt his image as an artisanal brewer. Regardless of how he did it, I'm thankful that Pierre Celis came to the US and brewed his beers. I still miss that Gran Cru. Jim Layton Howe, TX Return to table of contents

Date: Tue, 21 Dec 2004 10:46:12 -0500 From: "Dave Burley" <Dave_Burley at charter.net> Subject: Too too serious, Yeast viability Brewsters: Robert Sandefer took me too seriously in my comments on taxonomy changes. However, he acknowledges and then defends the politics involved in the "academic" community and the ensuing name changes. Then he follows up by wanting to make SWMBO more PC. This just proves my point. Is NOTHING Sacred? My basic point was that taxonomy's supposed purpose is to communicate with clarity, so there is no misunderstanding. Constantly changing the naming without noting the change has the opposite effect. This, of course, does not bother academic insiders, since they are often driven by academic politics and publishing yet one more article about less and less, not clarity. I suggest any communication, in which there has been a major name change, include all the terms at least once in any publication where it is used, perhaps in the following manner: L. sanfrancisensis ( formerly L. sanfrancisco) and Candida humilis ( formerly C. milleri or Torulopsis holmii) And as far as your PC name change of "She" to "Spouse" in SWMBO, who says you have to be married to have a SWMBO anyway and who really cares? I mean, you even missed the obvious PC thing. Suppose it is two guys living together in sexual bliss, butt, thankfully, unmarried, at least in most states? Would you propose HWMBO? or maybe WWMBO ( Whoever who must be obeyed)? The documented phrase is SHE Who Must Be Obeyed. What gives you or any other PC type the right to try to butt into our sacred, mostly male, bastion and try to spread your poison? I strongly believe all wishing to be so, must be included in a positive manner, but this doesn't mean every situation, because we are all different, which PC blindly refuses to recognize. I celebrate all female brewers ( esp those here on HBD) who, thankfully and historically, were the original Brewsters. But, personally, I think we as a society have been too tolerant of PC for too long. It has gotten us nowhere but confused. Remember "majority rules" ( whatever happened to that phrase?) guarantees the society will survive for the good of most of its members. SWMBO is just intended to be funny - a loving, smiling, approving comment on the male position in the conventional household, recognizing the real power there, not a put down of anyone. - ------------------------ /Fredrik, I don't have the original reference here, but my recollection is that the early work in Carlsberg showed that the true lager yeast S. carlsbergensis ( or is it S. uvarum or S cerevisiae var carlsbergensis or S. uvarum var carlsbergensis or ....?) were still viable after 30 years under distilled water and at room temperature. BTW if you want to see a classic example supporting my above comments and how our taxes are being spent, check out http://www.epa.gov/biotech_rule/fra/fra010.htm. by TSCA/EPA "Saccharomyces uvarum Final Risk Assessment" They even suggest it might be good idea to change this name to S. bayanus - wine yeast famous for it production of champagne bubbles, but waffle away.

Date: Tue, 21 Dec 2004 11:06:49 -0500 From: Mike_Andrews at vfc.com Subject: Re: wort reduction for caramel Jon, our beer club brewed a Thomas Hardy Ale clone a couple of weeks ago. The malt bill was 100 percent pale malt (22lbs) for a 6 gallon batch. We started out with 12 gallons in the brew kettle and boiled it down to 6. I transferred this beer a few days ago and the color resembles an english bitter with 10 percent crystal 60. The flavor is definitely sweet, and warm, but I expect this to mellow as the beer ages over the next year or two. I guess the short answer is yes, you can get caramel flavor and color by reducing wort with a long boil. But, adjusting the malt bill makes for a much shorter brew day, and I'm not sure if the final product is any different. Mike Andrews Battleground Brewers Return to table of contents
Date: Tue, 21 Dec 2004 08:29:17 -0800 (PST) From: PAUL MANTOVANI <paul.mantovani at sbcglobal.net> Subject: SS mag drive pump I was able to find a very good deal on a pump on Ebay. It's a March stainless steel magnetic drive. Great pump, but I got to thinking, "What was this used for previously, cyanide, dioxin?" Who knows. What would be a good procedure to clean the pump assembly thoroughly so I wouldn't have to worry about what I'm adding to my beer? Is there a good chemical I can obtain that would remove any traces of whatever was previously going through this thing? It's completely stainless, so I don't think it could be impregnated with anything that couldn't be removed. Thanks in advance. Paul Return to table of contents
Date: Tue, 21 Dec 2004 10:52:12 -0600 From: "Craig S. Cottingham" <craig at cottingham.net> Subject: Re: Grain Storage I saw somewhere once a suggestion on how to keep stored grain safe from infestation. I wish I could remember where. Get a trash can big enough to hold the full sack of grain. Plastic should be fine, but metal resists chewing on by rodents if you're storing your grain where that might be a problem. The lid doesn't need to make an airtight seal, but the can itself should be free of air holes. If you don't trust yours, just line it with a plastic trash bag. Put the grain in the can along with a 1-lb block of dry ice. As the dry ice sublimes to CO2 gas, it will sink to the bottom of the can, displacing the oxygen. This has the dual effect of protecting the grain from oxidation and making it inhospitable for any beasties which might try to take up residence. Note: Don't seal the can (or the trash bag lining it, if you used one). One pound of dry ice produces about 60 gallons of CO2 gas at room temperature, assuming I still remember how to do math -- or, to put it another way, two atmospheres of pressure in a 30-gallon trash bag. - -- Craig S.

Life has settled down a bit for me and I have time for brewing once again. It also helps if SWMBO likes beer! I can see my old friends are still up to thier old tricks: Mr. Burley is still delivering the facts AJ is comming up with good ideas (like vittles vaults) Mr. Palmer is giving advice on stainless steel, once again Mr. Renner is still figuring out his coordinates and Pat, as usual, is cleaning up the mess. How about my mate from Down Under, Mr Sanders?

Date: Tue, 21 Dec 2004 16:31:32 -0800 (PST) From: Kent Fletcher <fletcherhomebrew at yahoo.com> Subject: Re: Williams Temp Controller II (was Theermostat Question) The controller qmeneely was asking about is the Johnson Controls A419 Electronic Temperature Control, with a Williams Brewing faceplate. To switch this unit from cooling mode to heating mode and still be able to just plug the controlled load into the existing outlet cord, he has to open the unit and change a small jumper, similar to the kind found on hard drives, mother boards, etc. If all you need is to be able to control a heater inside a fridge for fermentation purposes, all you need to do is connect an outlet with the hot line connected to the NO terminal on TB2, and the neutral wired with the other neutrals. As long as you use a resistive load (ordinary light bulbs, heating pad, etc.) you can run up to 10 amps on the NO contact. Note that this wiring will leave no dead band between heating and cooling, but if you use a low wattage heater, you shouldn't have any short cycling problems. If you still want to go with external switching, all you need is a micro size toggle and 22 or 24 ga wire, as you would just be substituting a swithc for the jumper, which operate at TTL level current (microamperes). Connect the toggle switch to Jumper 1 on P4, you shouldn't need to switch Jumper 2. Thus, with one microtoggle, you can switch from Cooling (switch open or off) to Heating (switch closed or on) modes, both with cut-out at setpoint. In other words, when set to 68 in either mode, the load will be switched off when the temp reaches 68. Hope that helps, Kent Fletcher Brewing in So Cal Return to table of contents
