I forget exactly what I said in my post but what I meant was that Ecolab's "Iodophor II Sanitizing Udderwash" which Agway sells is not FDA approved. I know some people are currently using this. I talked with a rep at the St. Paul,MN office who told me which products are o.k. and which aren't. My notes don't say whether the Mikroclean is FDA approved but if that's what the label reads it must be. As I stated however, it was the reps opinion that I should use the "Diophor" product. It sounds as if they make many similar products of which more than one are probably o.k. to use. Sorry if there was any confusion. Someone also sent me a message telling me about a product called Proclean 200 found in restaurant supply shops. It sells for $22/gal. I rinse the iodophors despite the claim that it is not necessary. These agents are powerful enough where they could effect yeast growth if they do not fully evaporate. ~Zeek Return to table of contents
Date: Wed, 25 Jan 1995 21:22:16 -0800 (PST) From: Al Pacifico <pacifico at u.washington.edu> Subject: Wort oxygenation I brew in 10 gallon quanitities and do my first stage in a modified 10 gallon Cornelius-type keg. My kettle is a modified half-barrel keg with a stainless nipple on the bottom and a large hole cut in the top. My wort is chilled (possibly too much) in a countercurrent heat exchanger I made from copper tubing and rubber hose. Since I switched from fermenting in carboys to this stainless steel unit, I've noticed that fermentation has been less vigorous. When full, the fermenter is heavy and I can't really pitch the wort to oxygenate it (not that I ever did this to great extent when I used carboys). My hypotheses regarding reduced fermentation activity center around too little oxygenation or too much cooling. Since I never had this problem with carboys, I figure it is the oxygen. I have access to an oxygen tank and have been considering the following solutions. 1. Low tech: Drill holes in the end of the chiller an inch from the outlet so that air is sucked in (courtesy of Venturi). Potential problem is foaming wort, preventing me from maximizing quantity. Plus is that I don't have to beg my boss to let me have the oxygen tank for the weekend. 2. High tech #1: Add a pipe fitting that allows oxygen to be added to the hot wort as it enters the chiller. Plus is that cooling of the oxygen wort mixture would reduce foaming (I think) and turbulent flow through chiller would maximize oxygen-wort interface surface area. Potential badness is that oxygen tank would be close to burner and probably wouldn't explode, but you never know. 3. High tech #2: Stainless steel pipe to immerse in kettle and blow oxygen in. Disadvantage: solubility of oxygen in hot wort is lower at higher temperatures (probably insignificant). Advantage: simple, low cost, no foaming. 4. High tech #3: Seal primary fermenter and drive oxygen into wort under pressure. After a few hours, stop, bleed off pressure, and attach air lock. Advantage: eliminates the foam issue. Disadvantage: yeast could go nuts, overpressurize the keg, and I die in a bizarre brewing accident. Anyone have experience with this? I favor solution three. Has anyone had success with oxygenating wort that has just been boiling? Do any Jedi masters of chemistry know how much the oxygen solubility changes between 65F and 212F ?

Date: Wed, 25 Jan 1995 17:50:21 GMT From: ed.scolforo at berkshirebbs.com (Ed Scolforo) Subject: advanced homebrew seminar In HBD 1640 Dudley Leaphart shared his opinion that the American Brewer Guild's Advanced Homebrewing Seminar was essentially a waste of time for anyone beyond the beginning all grain level. Having just sent them $99 for one day of a two day seminar coming to Boston on March 18-19, I immediately panicked and called the ABG headquarters in Cal. I was advised to speak with Bruce Winner, the president. He was unavailable at that time but gave me the consideration of returning my call, even tho I said I would call him tomorrow.In his opinion, this course would deffinitely be informative for someone who's been all grain brewing for less that two years, such as myself. He invited me to talk to the seminar instructor, Ashton Lewis, and if I still felt the seminar had nothing to offer me, they would refund me my check.I thought this to be fair, and was impressed at the quick attention given me. I'm going to attend this seminar based on Mr. Winner's recommendation. I offer this to you in hopes it may be of help. Ed Scolforo Ed.scolforo at berkshirebbs.com Return to table of contents

Date: Thu, 26 Jan 1995 11:07:06 -0500 From: Robert Rybczynski <robert at umbc.edu> Subject: Removing lather due to aeration Last night I had to shake a half-full carboy to aerate the wort. When I was done, a lather about 1 foot thick had formed. This created a problem with getting the rest of the water into the carboy. To make a long story short, I did the following: filled the carboy as high as I could with boiled-then-cooled water, put a solid stopper in the mouth of the carboy, put the carboy in the kitchen sink, and used the sprayer to gently spray hot water onto the carboy were the airspace was in the carboy. This increased the air pressure in the carboy, which forced down the lather! Some notes: 1. The termperature of the wort was not elevated by a noticable amount. The carboy was in a stainless steel sink that acted as a heat sink. 2. Every so often I removed the stopper and added more water to decrease the airspace. I found that it was best to heat one small spot first, then spread out. 3. I had to be careful that the carboy did not block the drain. At one point I noticed that the carboy was sitting in a pool of hot water because of this. Robert Rybczynski robert at umbc.edu Return to table of contents

I'll be Walnut Creek, CA next week and am looking for a place to buy Deschutes Brewery's (Bend, OR) Black Butte Porter and Bachelor Bitter. I've called the brewery but they go through a distributor and I had no luck with that call for details. I looked in a few places last time I was in CA (no luck), hence the post. I'll have a car so can drive anywhere in the Bay area. Private reply please. I'll re-ask a question from earlier this week. Looking for experiences of HBD brewers on using lots of crystal in a predominately pale malt batch, i.e. 2-3 lbs of crystal in a grist with about 8 lbs pale 2-row. Haven't found any information on this in my available sources. Private reply also. Thanks, Bruce DeBolt Return to table of contents

Date: Thu, 26 Jan 95 11:50:59 EST From: dweller at GVSU.EDU (RONALD DWELLE) Subject: fix mash / ale into lager I've seen several references to George Fix's notes on a 40-60-70 mash in HBD. I obviously missed the original post and can't now locate it. Can someone post the HBD-number or zap me a copy--dweller at gvsu.edu. On the subject, is there a way for us cyber-impaired to search the sierra archives (I don't think I have any built-in software to do it). Another subject: I love lagers & pilseners but brew only ales, because of equipment, space, facility limitations, and that's not likely to change. Is there anything published, or do any of you list gurus have some good ideas, on how to replicate a nice German lager with an ale receipe and ale yeast?

I have noticed that the mash does >taste sweet at the end of the 140F rest, although I haven't measured >S.G. at this point. I am aware of 4 different professional references which cite 4 different temperatures for malt gelatinization. I have not done direct measurements of the carbohydrate spectrum at the various stages of the mash (this would make a neat Masters thesis for someone with an access to a HPLC!), but it my feeling that gelantinization starts at much lower temperatures than 65C (149F), but probably is not complete until the temperatures reach the mid-60s. Nevertheless, I have found there is significant beta-amalase activity and concurrent maltose production at 60C (140F). In fact, varing the time taken at 60C is the best scheme known to me for varing wort fermentability. The fermentability that is actually achieved depends a lot of other factors other than wort fermentability. These include yeast strain, yeast viability, wort aeration, fermenter geometry, et al. (Bob Jones discussed some of these issue at the National Conference in Denver). The best way known to me for identifying the contribution from wort fermentability is by a forced fermentation test (FFT - not to be confused with the Fast Fourier Transform!). Remove a ~liter of chilled wort, aerate it, and pitch with 2-3 times the normal concentration of yeast (say, 50-60 million cells per ml.). Hold the temperature at 25 C (77F), and within 72-96 hrs. all the fermentables should be metabolized. The final gravity from the FFT will likely be a tad lower than what is achieved in the main batch, but the two should not differ by much. What I like about a FFT is that it gives us a handle on wort fermentability as well as info on how well we are doing with wort aeration and yeast management. George Fix Return to table of contents

Date: Thu, 26 Jan 95 10:50:22 MST From: Jeff Benjamin <benji at hpfcbug.fc.hp.com> Subject: Fat Tire, AOB I wanted to clear up any potential misinformation in Roger Grow's post about Fat Tire Ale (have to stick up for the hometown breweries). First of all New Belgium is in Fort Collins, Colorado, not Lakewood. New Belgium Brewing makes Fat Tire, an amber ale, Sunshine Wheat, a wheat beer obviously, and several Trappist ales: Abbey, a single, Trippel, and an occasional Grand Cru. Roger mentions "that Fat Tire wheat taste", but I'm not so sure Fat Tire does contain any wheat. I'll see if Jeff Lebesch will tell me next time I bump into him. The second recipe says to use "#1214 Belgum Ale" or "culture from several bottles of Fat Tire Belgium Ale". Well, there's no such thing as "Fat Tire Belgium Ale". The recipe looks more like an amber ale than a trappist single, but it's not clear to me which one they're trying to emulate. Needless to say, the recipe as is might be tasty, but won't approximate anything that New Belgium brews. The folks who do the Rocky Mountain Homebrew newletter had better be more careful about their sources. Okay, on to something that might interest more than three people. Lee Bussy asks about email address for the Association of Brewers (AOB). I recently received an informational mailing from someone I know who works at AOB.

Date: Thu, 26 Jan 95 13:53:14 EST From: Eamonn McKernan <eamonn at rainbow.physics.utoronto.ca> Subject: Dave's bar/ recipe request/ RIMS Warning: I have never kegged in my life. Having said that, it seems like Dave could always have cold beer out of his tap if he had one of those cold plates people stick inn their fridge. The beer still in the line coming up from the basement would be warm, and a cold plate cold handle chilling it, and by the time the cold plate was done in (they're only good for a few beers at one time), cold beer from the keg would be on its way up, and wouldn't need chilling. Just a thought. A friend asked if I could post a recipe request. He wants a reasnoably dark (read: flavourful) ale. Kind of along the lines of a Smithwicks, but with less bitterness, yet more hop flavour. I guess that would invole later additions of a fair amount of hops. Malt extract only. TIA Finally, a truly different request: I want to make a RIMS setup that is more complicated than it need be. More complicated in what way? Doesn't matter, as long as it works. WHY??? I'm taking a graduate course in microprocessor interfacing techniques. My final project is to build anything I want, that involves some reasonable level of computer interfacing. My first thought: an automated beermaker! But a RIMS setup doesn't need terribly much control. The software end would only require temperature control, a pump, and maybe some valves. The prof wants some reasonably complicated programming to happen, so the RIMS seems too basic. RIMS builders feel free to correct me on this point. With a RIMS the hardware side would be truly challenging, but won't be worth many marks. One further complication: I don't have a computer, and don't want to spend tons of money on this project. I figure grab an obsolete 8086 from somewhere, and hopefully only fork out <$200 (preferably <$100) for it and the kettles, tubing, pump, etc. Does anyone think this to be even remotely possible?

For example I just brewed a Scotch Ale, the recipe staed an OG of 1.060 and my measured OG was 1.050. The interesting thing is that I used more crystal malt and carapils than the recipe called for. I steeped the grains for about 30 min between 150 and 170 degrees. Then added the extract and boiled for 75 minutes. My brewing is extract based with specialty grains added. The beer tastes good, however, I am curious about the variation in gravity. What am I doing "wrong"? TIA, Kevin Return to table of contents
Date: Thu, 26 Jan 1995 12:13:59 -0800 From: folsom at ix.netcom.com (Alan Folsom) Subject: Hop Utilization I am going through the process of trying to calculate IBU values, and have read the formulas by Rager in the 1990 special issue of Zymurgy, as well as the book "Using Hops" by Mark Garetz. After some experimentation, it seems the biggest affect on calculated IBU levels is the %utilization value, despite all the other correction factors discussed in the Garetz book. Unfortunately, these two sources differ widely, and I recall some discussion as to the appropriate utilization values being different from both sources. Does anyone have any wisdom to share on appropriate values to use for the %utilization for different boil times?

The tech. representative I spoke to insists ATC does not adjust the reading to reflect that sample at room temperature. Also a pH conversion chart to compensate for temperature can be found on bottles of Corning (and probably other) buffer solutions.

I have been on about this since the day it was uploaded to the archives, and after a fairly extensive effort in collecting data, have contributed to Mike's decision to allow the user to choose which set of utilization data to use in making IBU calcs. This option will be included in subsequent releases. I will be collecting the utilization data for him and will send it along in a couple of days. This past weekend, while Domenick Venezia was visiting, he, Andy Walsh, Ken Willing, Chris Pittock, and myself had a beer 'n' dinner 'n' beer evening at Kens's place, and several of Ken's beers had been made using the 3.1 formulations, and were conclusively identified to be way overbittered (no one knew until days later that 3.1 had been used). I have heard from many others via email and r.c.b. on this, and no one has supported the Garetz-based formulations. So: use 3.0c until the next version is released.

Date: Thu, 26 Jan 1995 16:27:17 GMT From: rmoucka at omn.com (Ronald Moucka) Subject: BBC hops/another use for steam Brewers, The day I posted my question about what ever happened to the Boston Beer Co hop offer, I received a calendar from BBC with their address and phone on the first page. Cool daily calendar with a beer quote or trivia for each day of the year. They can be had free of charge by writing BBC at The Brewery, 30 Germania St., Boston, MA 02130 or call 617 522- 3400. Say what you will about Jim Koch and his business practices, they make a decent beer and if you can overlook the blatant commercialism of their freebees, they are nice. Anyway, as for the hops, they are still available. According to the person answering the phone at BBC, they are waiting for a large enough number of orders to make a bulk mailing. One pound of Mittlefreuh hops (pellets I think) for $12. Send a check to the above address. My thanks to those of you who answered my post. Hope this answers any questions. On another note, I've noticed a lot of talk about steam lately. I have another use for steam that was suggested by a member of my local brew club. I've been using it for a few years now with no ill effects. I use steam to clean my kegs. I picked up a tea pot at a second hand store for 25 cents. Take a drilled rubber stopper (#8 I think) and insert a short piece of copper tubing (4"). Now attach a 4- 6' piece of hose to the copper tube and a liquid disconnect on the other end. Now simply insert the stopper in the tea pot and connect the liquid disconnect to the keg. Make sure you attach a gas disconnect to the other side of the keg to vent out the steam. Put some water in your tea pot and boil. The steam will sanitize the kegs and poppets in 15-20 minutes. Make sure your system is open or the pressure will build up and blow your stopper across the room in no time. Takes an hour or two to cool and you will want to drain the condensation from the keg.

The person you want to talk to is Lucy Sholley. She was very pleasant, and referred me to their mail fulfillment company. The person there told me that they (the fulfillment house) have nothing to do with any checks. BBC just sends them the names and they mail out the hops. She did promise to talk to Lucy and get back to me, and to send out my hops in the meantime. This all happened today before I got HBD, so I don't have a final resolution yet.

I am a new subscriber (Yes, I just recieved my third issue), I am glad to know such a group is available to us as brewers to talk about the wonderful substance called Beer. I want to reply to a couple of things I've seen so far this week. Re: Pictures of All Grain Brewing. The catolog from Hoptech has an excellent picture of their sparging system. Call them at 1-800-DRY-HOPS. I also consider them a Bible of info on Dry-Hopping. Re: A-B's Use Of Non-reuseable Bottles. Just one more reason to not drink any of Budmillercoors' products. One other poor excuse for bottles is clear Miller Genuine Draft bottles. A buddy of mine used some once and broke about 6 of them just during the capping, and about that many after a week in the bottles... Re: Coffee Beer. I tried a coffee porter once and had bad luck. This may be because I put the ground coffee in the primary fermenter, or it may be because I used too much coffee (1/4 pound!). The beer smelled like tomatoe vines (Yuck!). Keep us updated on the status of your brew, and the technique used. I would like to try again someday. Now for a Question: Does anyone out there have any good clip-art of Hops? I am a real big Hop-head and want to use it on letter heads, etc. If you do and it is on-line somewhere, Please either send it to me, or tell me where to send to to get it.

(From *Jeff* Renner) In HBD 1641, Al K. said: >Also, I recommend pre-boiling that 4 gallons of tapwater >the day before brewing 1) to sanitize it, 2) to drive off chlorine <snip> Since the Ann Arbor municipal water supply now uses monochloroamine to chlorinate its water, and this is essentially not removable by boiling (you have to use an activated charcoal filter), I thought I'd check to see how common this is. I spoke to Larry Sanford, the water chemist at the AA water treatment plant. He said that AA is probably the only plant in the state to use this, and he guesses that only about 15% of plants in the US do. I asked if it were required by federal regulations, and he said no, that they require only that a disinfectant be present in effective levels to the consumer's tap, and that this is the best method. It isn't new, either. Denver has been using it for 70 years. Ozone is used only the treatment plant; it doesn't last long enough to be effective in the mains. This has been the topic of some speculation in the past, including by me, and I hope this helps. If in doubt, phone your water treatment plant.

Date: Fri, 27 Jan 1995 03:04:06 -0500 From: Xtalale at aol.com Subject: Vacuum vs Pressure Siphoning Hi All, I'm a long-time lurker, first-time poster. I really think this forum is a gas! I've incorporated many tips/techniques that I've read here to my own process, so, after reading Dave Miller's column in the latest BT (vol. 5, #1) about the dangers of starting a siphon with pressure, I thought I'd share my method for vacuum siphoning. I know I'm not the first to think of this, but if it saves someone's life (or a precious batch of brew), than it's probably worth me breaking out of lurk. All that's needed is one of those orange carboy caps (you may have to try a few - some don't really fit tightly), a piece of 3/8" I.D. Tygon about 3 feet long (for applying the suction necessary to create a vacuum in the carboy), and a short piece (6" or so) of plastic racking cane (or copper tubing the same size) with several small "carburetor" holes drilled in it, for racking from the kettle and aerating the wort. If racking from primary, you'll need a longer piece (without holes, of course) that will reach to the bottom of the carboy to minimize splashing. Clean and sanitize the receiving carboy (and purge with carbon dioxide, if racking from primary) and the other above pieces, stick the piece of cane through the large center hole on the cap (leaving an inch or so sticking out of the top of the cap), attach the 'vacuum' Tygon to the stem part of the cap, and snap the cap onto the carboy. Attach a whole racking cane to one end of a longer piece of Tygon (a regular racking set-up) and stick the the other end of the 'racking' Tygon onto the end of the cane sticking out of the center hole on the carboy cap. Now, all you have to do is hold/suspend the end of the racking cane in the kettle/primary, and suck on the end of the 'vacuum' Tygon with one good, strong pull (use your mouth and cheeks more than your lungs and don't let it pull air back into the carboy from your mouth - practice with water first). You'll probably be surprised at how little effort is really needed to get a flow going. I find that if I pinch or bend the 'racking' Tygon slightly near its attachment to the racking cane, the bubble that forms there will go away. You'll observe that, once beer starts flowing, there will be a positive air flow 'out' of the Tygon that you sucked. Unless you let the vacuum in the carboy pull air out of your mouth while sucking, instead of beer into the other end, I believe you won't expose the beer to any potential contamination - at least, I've never experienced any. This description took far longer than the above procedure and probably reads as a pretty complicated technique, but it's really quite easy. I hope that the majority of the HBD readership feel that this was worth the length (whew!) and if I am wrong about the possibilty of contamination, someone please tell me! Thank Ninkasi for the HBD!

I've been racking from secondary into a corny keg, and >immediately placing it in the fridge with CO2 attached for carbonating. >Would I improve the taste of the beer by letting it "condition" at room >temperature after racking to the keg, and before chilling/carbonating? >How long? Lee, I would suggest force carbonating by gentle agitation, and then putting it in the fridge. The foam will subside overnight, and within a week the cold break will have settled. Perfectly carbonated, crystal clear beer... Use your pressure/temperature/volume chart to determine what you need to achieve the correct carbonation level. Example: my cellar temp is 60^ F. and I want 2.5 volumes of CO2. I purge the keg and rack the well settled (or preferably fined) beer over. Per the chart, I need approximately 23 psi. Pressurize your CO2 line and attach it to the keg. Sit on a chair with the keg across your lap, gas side up. Alternately raise one knee then the other for 10 minutes (in tune with, say, _American_Pie_ - avoid heavy metal!). That's it - you beer is now carbonated. Here is the chart: Volumes of CO2 desired Tmp 2.0 2.1 2.2 2.3 2.4 2.5 2.6 2.7 2.8 2.9 3.0 32F 3.5 4.4 5.4 6.3 7.3 8.2 9.2 10.1 11.0 12.0 12.9 34F 4.3 5.3 6.3 7.3 8.2 9.2 10.2 11.2 12.1 13.1 14.1 36F 5.1 6.2 7.2 8.2 9.2 10.2 11.2 12.3 13.3 14.3 15.3 38F 6.0 7.0 8.1 9.1 10.2 11.2 12.3 13.3 14.4 15.4 16.5 40F 6.8 7.9 9.0 10.1 11.2 12.3 13.4 14.4 15.5 16.6 17.7 42F 7.7 8.8 10.0 11.1 12.2 13.3 14.4 15.5 16.7 17.8 18.9 44F 8.6 9.7 10.9 12.1 13.2 14.4 15.5 16.7 17.8 19.0 20.1 46F 9.5 10.7 11.8 13.0 14.2 15.4 16.6 17.8 19.0 20.2 21.3 48F 10.4 11.6 12.8 14.0 15.3 16.5 17.7 18.9 20.1 21.4 22.6 50F 11.3 12.5 13.8 15.0 16.3 17.6 18.8 20.1 21.3 22.6 23.8 52F 12.2 13.5 14.8 16.1 17.3 18.6 19.9 21.2 22.5 23.8 25.1 54F 13.1 14.4 15.7 17.1 18.4 19.7 21.1 22.4 23.7 25.0 26.3 56F 14.0 15.4 16.7 18.1 19.5 20.8 22.2 23.6 24.9 26.3 27.6 58F 15.0 16.4 17.8 19.2 20.6 21.9 23.3 24.7 26.1 27.5 28.9 60F 15.9 17.3 18.8 20.2 21.6 23.1 24.5 25.9 27.4 28.8 30.2 62F 16.9 18.3 19.8 21.3 22.7 24.2 25.7 27.1 28.6 30.0 31.5 64F 17.8 19.3 20.8 22.3 23.8 25.3 26.8 28.3 29.8 31.3 32.8 66F 18.8 20.3 21.9 23.4 25.0 26.5 28.0 29.6 31.1 32.6 34.1 68F 19.8 21.4 22.9 24.5 26.1 27.6 29.2 30.8 32.4 33.9 35.5 70F 20.8 22.4 24.0 25.6 27.2 28.8 30.4 32.0 33.6 35.2 36.8 72F 21.8 23.4 25.1 26.7 28.4 30.0 31.6 33.3 34.9 36.5 38.2 74F 22.8 24.5 26.2 27.8 29.5 31.2 32.9 34.5 36.2 37.9 39.5 76F 23.8 25.5 27.2 29.0 30.7 32.4 34.1 35.8 37.5 39.2 40.9 78F 24.9 26.6 28.4 30.1 31.8 33.6 35.3 37.1 38.8 40.5 42.3 80F 25.9 27.7 29.5 31.2 33.0 34.8 36.6 38.3 40.1 41.9 43.7 Beers to be dispensed from the keg should be carbonated to between 2.0 and 2.5 volumes, depending on style.
