---------------------------------------------------------------------- Date: Thu, 20 Jun 2002 09:23:23 -0400 From: "Shawn E Lupold, Ph.D" <lupolds at jhmi.edu> Subject: De Koninck Recipe? After a recent trip to Belgium, my wife has decided that De Koninck is her absolute favorite beer. Unfortunately, it's very hard to find and expensive. I would like to try cloning it in my next brew. From what I remember, the beer has a less complex nose and taste compared to traditional Belgian Trappist or Tripples, but I have no idea where to start. If anyone is familiar with this beer or has attempted to clone it, I would appreciate some suggestions for grain bill, SG/FG, hops, yeast, etc. Thanks for your help. Shawn Return to table of contents
Date: Thu, 20 Jun 2002 06:24:52 -0700 (PDT) From: Paul Kensler <paul_kensler at yahoo.com> Subject: re: force carbonating "My problem is that my beer tastes/smells excellent until I force carbonate it. It then picks up stale and harsh flavors." Troy, I've successfully force-carbonated kegs and haven't noticed this problem, so all of my suggestiong might be just stating the obvious but do you purge the kegs after filling them with beer? Do you use an airstone and if so, do you purge it with CO2 before filling the keg? What temperature are your kegs while they are carbonating (kept cool or cold and out of direct sunlight, etc.)? It sounds like your bottled beers don't suffer these problems... have you tried splitting a batch to see how the exact same beer progresses in the bottle vs in the keg? Say kegging some in a 3 gallon keg and bottling the other 2 gallons (or if you don't have a 3 gallon keg, make a 6 gallon batch and keg 5, bottle 1 gallon). Could there be any other changes to your brewing process or equipment that happened at the same time that you started kegging that could be the cause of the oxidation / staling? I think its doubtful that your regulator is leaking air into the lines... if the regulator had a leak, the CO2 pressure in the system would be pushing CO2 out thereby preventing any air flowing in - plus your tanks wouldn't be lasting so long. I can't imagine it would be possible for your local CO2 supplier to have twice filled your tanks with pure O2? I don't know much about commercial gas operations, but the enormous danger in such a screw-up leads me to believe that there would be physical differences in O2 and CO2 tanks that would make that impossible. Is it possible that you got some beer up into the regulator and there is an infection in there? Any oil or lubricant coming out of the regulator? From your post it sounds like you've disassembled and cleaned everything. The second pressure guage on the regulator doesn't really change until the tank is almost empty - its not a very good indicator of how full the tank is. Depending on the size of your tank, they probably will last quite a while. I have a medium size tank (15 or 20#) and it seems to last forever. I guess one possible solution would be to prime and naturally carbonate the kegs - but if there truly is a problem with your CO2 or CO2 system, then you'd just be delaying the staling... no reason why you shouldn't be able to force carbonate... My force-carbonating procedure is to use a stainless carbonation stone. I flush C02 through the stone and through the beer-out dip tube before filling the keg. After the keg is full, I seal the top and purge / release three times before putting 10-15psi pressure on the keg. I'll then move the keg to my temperature controlled chest freezer and the next day (after its chilled) I hook up the gas to the carbonation stone and crank the psi up to 15-20 and check the keg every 12 hours or so until its just right. I hope this helps, Paul Kensler Gaithersburg, MD Return to table of contents

I live in NOLA too...hehehe, I just managed to get mine from some friends, and I didn't ask where they got them...didn't want to know. :-) Actually, one suggestion that was made to me was to go drive around Tulane and Loyola in that area, and go by the Frat. houses...quite often they have kegs there...offer them like $10-$20 bucks for them. Or, if worse comes to worse...I think a deposit on a keg is like $50, just rent a keg, and don't return it. Also, I've seen them for sale, often already converted (for crawfish boilers) in the local newspaper...check that out. I currently have 2, and soon will have 3....we just cut off the tops with a grinder...and in one of mine, we drilled a hole in the bottom and installed an EZ masher (get them at Brew Ha Ha on Magazine St.). I use this one as my mash/lauter tun. I use the other for sparge water...etc. This system works great for me...been doing 10 gallon batches with ease. Give these avenues a try...if they don't work, email me off list, and I'll ask around to see if there is a extra keg I can lay my hands of (besides my 3rd one...hehee). But, try the university thing...or ask one of the bars around here if they'd unload an empty one to you for a couple of $$'s.

Harsh, David writes ... >It seems Ohio may have figured it out - the state Senate passed a law >doubling the permitted alcohol content in beer to 12%! [...] But (I believe) failed to pass the rider that reduced the outrageous wine tax and state minimum price laws. Also the brewery must register their product w/ the state so maybe you'll see Sam Adam TripleBock but I wouldn't plan on finding many small brewery imports. The distilled product laws are still post-prohibition era ridiculous too. Oh well - it's a firm step into the 20th century, so now we're just one century behind in Slow-hio. -S Return to table of contents
Date: Thu, 20 Jun 2002 09:31:12 -0500 From: "the freeman's" <potsus at bellsouth.net> Subject: heat protection for thermo and sight glass While I do not have a sight glass or thermometer on "the perfesser's" boiler, I do have a sight glass and a thermocouple pick up on the HLT. I once heated that HLT with a burner and sought, as you are now doing, heat protection. I had a SS heat shield welded to the HLT just below the items in question to divert the flame away from them. It is possible to pop rivet that same protection to the side of a keg if you drill BELOW the weld line. Probably the best insulation in this instance is ceramic wool - this assumes you are not satisfied with simply diverting the heat. Any company that deals with kilns or fire brick will probably have a scrap that they will give you. Ceramic wool stops heat well enough that you can put a propane torch flame on one side of 1" of wool and then place your hand comfortably on the other side. If you can not readily find the ceramic wool, let me know. Bill Freeman aka Elder Rat KP Brewery - home of "the perfesser" Birmingham, AL Return to table of contents
Date: Thu, 20 Jun 2002 08:24:21 -0700 From: "Brian Schar" <schar at cardica.com> Subject: Troy's kegging problems Troy, I feel for you, as I had nothing but problems myself when I started kegging. My basic problem was different; no matter how much I tried, two out of every three batches were flat upon dispensing, no matter how much priming sugar or force carbonation I used. There wasn't a leak anywhere in my system, either. I spent so much time worrying about it that I realized it was easier to just go back to bottling. I am back to enjoying brewing a lot more now. Plus, it's easier to give bottles away to friends and enter competitions. Now that you mention it, the last batch I kegged had a stale cardboard flavor, which my beers never have, and I used my standard brewing process. I would recommend putting your CO2 tank and kegs someplace cool and dry in your garage for a few years, or giving them to someone in your homebrew club.

Boneyard Brewoff)has used this new (non-BJCP?) category to provide a place for a considerable amount of the stout being brewed (it seems) by HB today. Has anyone else adopted it?

Date: Thu, 20 Jun 2002 12:49:48 -0400 From: "Dave Burley" <Dave_Burley at charter.net> Subject: Kegging staleness Brewsters: Troy complains about the impact kegging has on his stability of his beer. Stale flavors ruin his kegged beer. I suspect you are not removing the oxygen from the keg. Simply spraying in CO2 gas in the keg, as is often suggested, will not do it due to the fact that gases are infinitely mixable, especially in a small space like a keg. Some years ago I posted a calculation that it would take 100 keg volumes of CO2 to reduce the oxygen to 1% of its level in air. And that is still not enough to ensure stability. But I figured out how to do it. Fill your keg with sanitized water and push out the water with CO2 gas. This will guarantee you have all the oxygen out of the keg. Then fill the keg through the "out" port if you can pressurize your beer or are transferring it from keg to keg, in the case you are filtering it, for example. Be sure to open the relief valve at the top of the keg. Or I most often just carefully loosen the lid and slide a tube into partially covered keg and fill from the bottom up. This gives you a CO2 blanket all the way to the top which works just fine. Put on the lid, open the relief valve and shoot in some CO2 on the "in" side to sweep the remaining gaseous area clear of any air. You will need a set of CO2 hoses and hookups since in and out have slightly different connections. Hope this helps. Keep on Brewin' Dave Burley. Return to table of contents

Date: Thu, 20 Jun 2002 12:05:15 -0700 From: "Kent Fletcher" <kfletcher at socal.rr.com> Subject: Subject: I need some help - harsh flavors after carbonating Troy, You may be overdoing it in scrubbing the cornies. It is possible to scrub through the surface oxide layer on stainless steel, exposing iron which can certainly produce off flavors in the finished beer. If this is the case, the steel can be "re-passivated" to restore the protective oxide layer. John Palmer posted an excellent treatment, it's at: http://hbd.org/hbd/archive/3326.html#3326-9 You might try this before kegging your next brew.

Date: Thu, 20 Jun 2002 15:26:50 -0400 From: "Czerpak, Pete" <Pete.Czerpak at siigroup.com> Subject: Luke's ZAPAP In HBD#3967 Luke asks about his heated ZAPAP style masher and how long it takes to clear. As many people, my first mash/sparge device was a Zapap. I actually mashed in the oven in a 5 gallon pot and then gently (sometimes and sometimes not) dumped my mash into my Zapap which was also lined with a large grain bag that I reused between batches. I used the grain bag to assist in the holding back on fines particles that could make it through my Zapap holes. It seemed to work okay. After dumping I would let the bed set for 15 minutes. So I batch sparge normally and I don't usually recirculate more than 2 to 4 qts (maybe 10 to 15 minutes) generally on 5 gallon batches. I don't shoot for crystal clear but more of a generally clear of larger particles. I find that excessive recirculation in the chase for crystal clear wort may lead to excessive oxidation of the mash liquors. When I drain my primary runnings, it took about 15 to 20 minutes. And maybe 10 to 15 minutes to drain my second runnings. Also, I would let the grain bed sit for 15 minutes after adding my full batch sparge water to settle the grain bed. I currently use a Phils Phalse in a 10 gallon Gott and I generally see faster clearing of wort. In your setup, you probably want to minimize the stirring of the mash which would forces fines through the fine mesh (and out of their filter bed) into the liquor takeoff pickup device.

Date: Thu, 20 Jun 2002 15:35:59 -0400 From: Martin_Brungard at URSCorp.com Subject: Re: Spoiled Results - Argh! Chad Gould had some good observations regarding sanitation that I can reinforce. He mentions "sanitation is 90% physical, 10% chemical - overreliance on chemicals is not a good idea". I was just reading one of my water and wastewater trade magazines that had an article on biologic contamination. They mentioned that psuedomonas aueralis (sp?) is a very common bug. What makes it particularly difficult to combat is that it is one of those slime-film producing bacteria. The film protects the organism from attack by chemicals and such. The article said that the film can be produced by the bug after it has attached itself to a surface for about 30 minutes. One consideration here is that the article dealt with potable water systems. These things can't be chemically cleaned with the harsh things we can apply, the water system is always in use! The point here is that there may not be any substitute for scrubbing, as Chad mentions. Scrub where you can. This certainly gives me a reason to be concerned for my counter-flow chiller. Hopefully my PBW regimen is sufficient to keep the bugs out!

(Marc Donnelly) Sad to say that to the best of my knowledge there are only two left in downtown: Rock Bottom on 4th adjacent to Horton Plaza and Karl Strauss at Columbia and B streets. There is also a place named Henry's on 5th that has Stone Brewing ales on tap and a few "Irish Pubs" that have the usual British stuff. Return to table of contents
Date: Thu, 20 Jun 2002 18:01:06 -0700 (PDT) From: Kent Fletcher <fletcherhomebrew at yahoo.com> Subject: Re: How to protect sight tube from heat? Gary, The thermometer should not be affected by the temperature. As to your sight tube, it depends on the material. You mentioned "rubber" but your tube is more likely made from PVC or polyurethane. Several homebrewers have made shields by using a length of stiff tubing, cutting out a long window with grinder. You could also attach a metal shield below the sight tube. Or you could upgrade to teflon tubing - FEP is translucent, available in all of the popular diameters, is rated up to 400 deg F. McMaster-Carr http://www.mcmaster.com/ carries all of these.

If you're looking to convert the keg yourself, you might try contacting your local beer DISTRIBUTOR, and asking if you can purchase a "retired" keg. And don't forget local metal scrap businesses.

Date: Thu, 20 Jun 2002 21:19:16 -0400 From: Peter Collins & Sara Wilbur <sarapete at sympatico.ca> Subject: newbie questions Hi all, I just joined the HBD digest and am quite excited about the wealth of information available and the exchanges that go on here. I am an intermediate-level homebrewer and have been for about five years. My questions are as a newbie to the digest, not so much as a newbie to brewing and are mostly specific to the area in which I live (Cambridge, Ontario): 1. I am curious as to where homebrewers in my area buy their ingredients. Currently I am travelling to Toronto to "Brew Your Own" to buy my grains, extracts and yeasts. I would love to find something closer but have not had good response from local BOP's and none of the wine BOP's have any idea what I am looking for. My biggest concern is yeast as I use liquid yeasts. 2. Has anybody ever ordered stuff or had any dealings with "Paddock Wood" in Saskatchewan? I found their site online tonight and it piqued my interest. Being able to order and have the ingredients delivered is ideal but would it be worth it? 3. I want to build an external thermostat for my beer fridge. Does anybody know where I can get the necessary equipment to do so locally? Is it more worth my while to just get one ready-made? 4. Are there any local homebrew clubs? I have called the BOP's for some advice but in their words "We don't make any money off you homebrewers." I would prefer to not have to deal with them in the future. I appreciate your input and your patience with my questions. I would be glad to have personal responses in addition to or instead of digest responses. Please feel free to respond to sarapete at sympatico.ca. Thanks again for your time.

Date: Thu, 20 Jun 2002 23:08:58 -0400 From: "Steven P. Bellner" <sbellner at chartertn.net> Subject: Wort Aeration Sterilization Question I would like to ask the collective a question about wort aeration. I have a powerful aquarium pump and a homemade carbon odor filter, and was going to use this device to aerate my wort during tomorrow's brew. I do not have a HEPA filter on-hand. Would it be advisable to pass the air through a 50-50 mixture of vodka/water before blowing it into the wort? Would there be any beneficial sanitazation of the air with this setup, or am I best served by waiting for a HEPA, or does it really even matter? I am am beginner/intermediate extract/specialty grain brewer, and I try to improve my technique on each new batch I brew. I have gone from Mr. Beer (awful) to extract with grains, added a wort chiller, added Cornelius kegging, and am now concentrating on improving my pitching technique. I would certainly appreciate hearing from the voices of experience. Thanks. Steven P. Bellner sbellner at chartertn.net Return to table of contents
