---------------------------------------------------------------------- Date: Tue, 7 Dec 2004 22:40:59 -0600 From: "Byron Towles" <beer.man at cox.net> Subject: Acetaldehyde troubles In digest #4668, Bob Barrette laments his CAP with much acetaldehyde. Bob, is it possible you could claim your beer was Beechwood aged? If the members of the party are typical american lawnmower beer consumers, they might like that idea. "Hey, old Bob even made this one beechwood aged like Bud." Or, for that matter, since the people drinking it probably aren't going to be experienced judges and know what off flavors to taste for, you could simply tell them that the flavor is supposed to be there, if it comes up at all. Of course, all this is pure speculation, as the degree of Acetaldehyde will determine how much or how little selling of the idea is required. Just my 2 cents from way down yonder in New Orleans.

Bob, I'm just curious..what yeast did you use? A couple years ago I decided to give dry yeast another try, and brewed a lager with S23 dry lager yeast (Saflager). That beer tasted and smelled like green apple cider. I'll bet that crowd would like it.To protect your reputation, just make the disclaimer right away that you aren't happy with it.

Date: Wed, 08 Dec 2004 08:10:34 -0500 From: Randy Ricchi <rricchi at houghton.k12.mi.us> Subject: Rootbeer Ed Jones is asking about rootbeer recipes. I've been making rootbeer from extracts for quite awhile for my wife. I use the Rainbow brand of extract. The secret, at least for me, is to use a mixture of rootbeer extract and cream soda extract. One bottle of Rainbow extract is 2 oz. and is supposed to be sufficient for 4 gallons of soda. I use a half bottle each of rootbeer and cream soda in a 3 gallon batch which I mix directly in my 3 gallon soda keg and force carbonate. Use 2.5 #'s of sugar, or substitute Splenda if you prefer. The Splenda version will not be as sweet or as full bodied as the sugar version. Rootbeer extract has juniper as one of it's flavorings, and I think it's too overpowering if you use just rootbeer extract. That's why I mix it with the cream soda extract, which has a very strong vanilla flavor. The two flavors complement each other nicely. I'd like to try other brands of extracts but they aren't available locally. Return to table of contents

Date: Wed, 08 Dec 2004 14:00:16 +0000 From: "A.J deLange" <ajdel at cox.net> Subject: Acetaldehyde Acetaldehyde is very volatile so you might try scrubbing it out with CO2 (this is what should happen gradually with lagering - you will just try to speed it up). Assuming the beer is in a corny pressurize to say 30 psig, leave for a couple of days to let the gas dissolve, bleed down to 5 or less and repeat tasting as you go until the acetaldehyde is at an acceptable level or it's clear this scheme isn't working.

I think it was www.arrogantbastard.com For my wine friends I ordered the "Don't break the bottle" wine bottle puzzle which is a wooden contraption that you have to figure out first before you can get to the wine. A search for the above name will give lots of sources for this gift. Just placed both orders yesterday, so can't comment on the service or quality of either yet. Return to table of contents

Yes, I have done it successfully several times, having first seen it suggested on the HBD. No problems with contamination, although that risk exists if you are not reasonably careful. But I still prefer to re-pitch the yeast from the primary, no starter required. Greg in Chicago Return to table of contents

Starting out, when you serve the first few beers that you made to your friends, you often say, "Oh my God, this is the best beer ever made." Usually they grimace as they drink it and look at you like you are smoking crack. Years of experience later, when you serve beer to your friends that you've brewed, you often warn them first about all the flaws and problems with the beer and they usually say, "Oh my God, this is the best beer ever made." I say serve it. Just my take. Dave Tucson, AZ >I made 10 gallons of CAP for a friends Christmas party to try to >satisfy the non craft beer drinking crowd.

Date: Wed, 8 Dec 2004 12:24:47 -0500 From: "Jason Henning" <jason at thehennings.com> Subject: re: White Labs vials In HBD-4668, jhandy asks about splitting WhiteLab tubes. Yes, you can open, use half and store vials with reasonable care. If you can't, you probably can't brew in the first place. Here's what I do. I dump a fresh tube in my wort. Since it's fresh, I don't build a starter. The tube will still has a bit of yeast left in it. I then fill the tube 2/3rds with wort and let it ferment with the lid on tight. I bleed the pressure every few days. Here's a picture http://thehennings.com/images/brc/wl-reuse.jpg. You can see the dab of yeast in the bottom of the vials. It doesn't give a lot of yeast but enough to build up with starters. Since I'm storing this yeast for the future, I already expect to have to build a starter.

Date: Wed, 8 Dec 2004 09:30:00 -0800 (PST) From: Kent Fletcher <fletcherhomebrew at yahoo.com> Subject: Re: Welded Fittings You can USUALLY get another 1/4 turn with the ball valve, because you have a nipple connecting the valve to the coupling, hence doubling the range of adjustment. With the thermometer and elbow, though, you're much better off indexing the fitting before welding. Be sure to wrap the male threads with teflon tape for your try fitting.

My response is that it IS possible but would not recommend long term storage of the remainder. I have had good luck storing harvested yeast in the vials that have been sanitized.

Date: Wed, 8 Dec 2004 13:30:11 -0500 From: Chris Collier <CCollier at lanierclothes.com> Subject: External thermostats Has anyone had any luck putting an external thermostat on a side by side refrigerator so you can lager on the refrigeration side and serve from the freezer side? Seems logical that it would work if you could balance the temperatures with a little trial and error. I currently use a chest freezer for serving and other than the excessive condensation that needs to be cleaned up, it works fine. That makes me wonder if the condensation be a problem on an upright since it might run onto the floor. Regardless, I plan on trying this after my kitchen project is complete in January and will post results. Thanks, Chris Collier ATL, GA Auburn should be in the Orange Bowl! Return to table of contents
Date: Wed, 8 Dec 2004 11:00:58 -0800 From: RiedelD at pac.dfo-mpo.gc.ca Subject: What is starch content of a pLambic? When you make a pLambic wort, you attempt to make it dextrinous and with some unconverted starch. My question is: how much starch? 1%? 5%? This doesn't seem to be a published number. The reason I ask is that I have an under-soured batch. I'm planning to feed the lactobacillus/pedio bacteria in an attempt to get some lactic acid increase. I'm going to use a boiled flour and water mixture as food. What I'm wondering is how much flour? My batch was on the order 4kg of grist. 1% is 40g of flour - for whatever reason, this seems a little low. Maybe 100g? Does anyone have any experience or knowledge to share on this topic? A few details: 1.047 SG, pils/raw wheat grist, attempted modified turbid-mash but found I couldn't denature enzymes fast enough to prevent full-conversion, pitched XL pack of Wyeast 3278, beer is currently 13 months old, brett character is very good, but too dominant. thanks, Dave Riedel Victoria, BC, Canada Return to table of contents
Date: Wed, 08 Dec 2004 13:09:13 -0600 From: Jeffrey Will <Jeff.Will at valpo.edu> Subject: high temp fermentation Hi. I'm a newbie, so maybe this will sound like a stupid question, but I'd like some help. I made my first all-grain batch Sunday. It's a brown ale. I used Irish Ale yeast (with a starter solution) and my starting gravity was 1.045. When I pitched the yeast, my temp was around 65. I wanted to go a little higher, so I left it in a warm place overnight, thinking that it would only change 3-5 degrees by the time I woke up to check on it. However, by morning, it was up to 78. (Don't really know how that happened, maybe exothermic processes from the yeast.) So I put it in a cooler, temp controlled place. I got it down to 72 by the afternoon, and to 66 by the evening. I've kept it at a constant 65 for the past two days. Here's a rough profile of temp vs. time. (Best viewed w/ a fixed-space font): 80 | | 78 | * * | * * 76 | * * | * 74 | * | * 72 | | * * 70 | * | * 68 | * | * 66 |* * * |_________________________________________________________________ Pitch 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 My questions: Is the batch going to be ruined? Will it be all banana-flavored? Is there anything special I should do now? I figured keeping it at a lower temp may help. I'm also going to definitely do a secondary. Thanks for any help... feel free to mail me directly if you don't want to clog up the list. (jeff.will at valpo.edu) Jeff Return to table of contents
Date: Wed, 8 Dec 2004 11:37:56 -0800 From: "Mike Sharp" <rdcpro at hotmail.com> Subject: Welded fittings on a kettle Paul wonders how others handle welded fittings so they orient correctly. Stainless has a tendency to gall, but you can usually get enough turns to orient a fitting. It depends a bit on how you're putting it together. A coupling welded to a kettle, with a close nipple and a valve can probably be oriented no matter what. A male nipple and a valve...maybe. Frankly, I prefer sanitary fittings. You can often get them fairly reasonably priced on ebay. I've obtained 3/4" sanitary ferrules pretty cheaply, and a while back bought two stainless sanitary ball valves with 3/4" sanitary fittings for something like $20. It costs more initially, but it's the way to go, because you can disassemble it entirely for cleaning. With threaded couplings, each time you do this, the fitting will tighten in a different location, farther around, or else it will gall and get messed up entirely.

Date: Wed, 8 Dec 2004 15:05:21 EST From: DakBrew at aol.com Subject: Beer gas folly { Quote Calvin Perilloux Mon, 6 Dec 2004 } No surprise there, and I have to agree with Dave Burley who already pointed out that beer gas is only part CO2, and so you'll only have the partial pressure component of CO2 on your beer instead of the gauge pressure. - ---------- { Me } You Lost me right there. Since when did pressure stop being pressure? The is stil the pressure in the keg is still what ever the regulator states. - -------------- { Quote Calvin Perilloux Mon, 6 Dec 2004 } I think most beer gas is 75% N2 and 25% CO2 (look that up -- don't trust me on that). Let's pick some numbers for the carbonation of your hefeweizen and assume that it's in equilibrium at 40 F at 16 psi CO2. It's fine if your top pressure is 16 psi of pure CO2, but if it's beer gas instead, then you're actually getting a partial pressure of only 4 psi of CO2. CO2 will come out of the beer to compensate. - ----------- { Me ) I dont buy that for one second. why the pressure being exerted on the Beer and CO2 in solution is still in 16 psi regardlass of what the gas mix is. If CO2 came out of solution the pressure in the keg would increase. - ---------- { Quote Calvin Perilloux Mon, 6 Dec 2004 } I doubt it would be practical to jack the top pressure up to 4 x 16 psi = 64 psi! Yow, think of the beer fountain that will hit the barmaid when that jet hits the bottom of the Weissbier glass! - ------------ { Me } Yea - ------------ { Quote Calvin Perilloux Mon, 6 Dec 2004 } This is why beer gas is usually used for low-carbonation ales, and definitely NOT for Weissbier. - ------------ Huh? I was always under the impression that beer gas was used in bars with long runs from the coolers to the taps, Regardless of the beer style. Hopefuly someone with some technical background can prove one of us right. Dan k Return to table of contents
Date: Wed, 8 Dec 2004 16:25:50 -0500 From: leavitdg at plattsburgh.edu Subject: Belgians (and re-using yeast) I have been re-using my yeasts now for some time, and just had a string of good luck with an Abbey Ale yeast, and feel the need to share, in that they all (so far) are tasting very good to me. The yeast was Wyeast 1214 Belgian Abbey. The first use of the yeast was for a "Pale Abbey Ale": 9 lb Moravian Pilsner Malt (not the under modified) .5 lb Wheat malt .5 lb Special Aromatic malt single infusion at 150 or so, mashout 22.6 ibu's of home gouldings, and saaz pellets og 1.043 fg 1.010 abv= 4.3% The second use of the yeast (now a cake) was for an "Amber Abbey": 5 lb pale malt 4 lb pilsner malt 1 lb wheat malt .5 lb Special aromatic .5 cara-amber two stage infusion, 146 and 156 F, 27 ibu's of home gouldings. og 1.051 fg 1.010 abv= 5.4% The third use of the yeast (still a cake) was for a "Brown Abbey": 10 lb maris otter 2 row .25 lb brown malt (Fawcett's) .5 carapils .25 special B 1 lb wheat single stage infusion near 156F, mashout, didn't calculate ibu's, but used home gouldings and Brewer's Gold hops og 1.063 fg 1.015 abv = 6.3% The forth, and maybe final use of the yeast was for a "Havasupai Red Abbey" (having recently returned from a successful trip down to the bottom of the Grand Canyon): 11 lb 2 row pale 1.5 wheat .5 cara-amber 2 step infusion , home grown gouldings hops. og 1.066 fg 1.013 abv= 7% Why present all of this here, you ask? So that I can get feedback on the recipes, methods, and share with those who have not re-used yeast. I know that I could wash the yeast (have not learned how to do so yet), but so far I have not gotten off-flavors which I can recognize as such. Happy Brewing! Darrell Return to table of contents
