Take me to your lager... As you may have notices, I have eliminated the delivery of the HBD on weekends; this to ensure the queue has an "ambient level" which facilitates our low-level moderation policy without causing a flood of spam into the Digest. At the request of friend Jeff Renner, I am forcing the generation of the HBD today to ensure the timeliness of Jeff's sad news contained herein. The HBD mourns the loss of Steve Ford, a true friend to the craft. May God rest his souls and bring comfort his friends and family. - -- - God bless America!

Date: Fri, 12 Mar 2004 15:56:12 -0500 From: Jeff Renner <jeffrenner at comcast.net> Subject: Sad News Brewers I am saddened to report to you all that homebrewer Steve Ford, of Overland Park, Kansas, passed away on Wednesday, March 10th, of a blood clot. Steve was an active, loved and respected member of the Kansas City Bier Meisters, the American Homebrewers Association and the Beer Judge Certification Program, and was a regular poster to HBD. Steve was one of only 36 BJCP Master Judges and was a candidate for the AHA Board of advisors. The AHA Board of Advisors' thoughts are with Steve's family, friends and club members. Today, there is beer in heaven, and we imagine that Steve has been welcomed there by Bill Pfeiffer and George Fix. The K.C. Bier Meisters have a memorial page at http://www.kcbiermeisters.org/SteveFord.htm His Kansas City Star obituary is at (cut and paste) http://www.legacy.com/kansascity/LegacySubPage2.asp?Page=LifeStory&PersonId=2019732 Steve's candidate bio is at http://www.beertown.org/homebrewing/election.html Jeff Renner AHA Board of Advisors Please honor Steve's memory by voting in the AHA board election - -- Jeff Renner in Ann Arbor, Michigan USA, JeffRenner at comcast.net "One never knows, do one?"

Date: Fri, 12 Mar 2004 07:47:39 -0600 From: Bev Blackwood II <bdb2 at bdb2.com> Subject: Thomas Hardy - My site visit I posted my version of the recipe to the list back in February. (I think) I really didn't set out to MAKE a T.H. clone, but after 4 years of aging, it comes pretty damn close in a side by side tasting with an older (1995, I seem to remember) Thomas Hardy. Does that mean mine will be as good come 2009? Well, like the age old question of: "How many licks it takes to get to the center of a Tootsie-Pop?" <insert sound of bottlecap opening & pouring a glass> "The world may never know..." I am down to my last bottle of that batch. :-) I actually visited the Dorchester brewery back in 1998 or thereabouts and will go back and review my videotape as to whether or not I discussed the grain bill with the brewer. I do recall I have shots of the fermentation log (I.E. the chalkboard) attached to the open copper lined fermenters they were using to make it, so I can likely get some OG's off the video. I was barely a homebrewer then, so I likely didn't know all the right questions to ask, but hopefully I got an answer inadvertently. I do know however, that the 1997 version of Thomas Hardy is not the same beer that the 1992-1996 versions were. The Eldridge-Pope brewery was busy trying to make lots of alco-pop at the time, along with light lagers and the standard cask ales and the 1997 reflected that in both its body and clarity. Will go back to the source material and see what I can glean from my visit. -BDB2 Bev D. Blackwood II http://www.bdb2.com Return to table of contents

I agree. I posted here a couple of years ago that I had a small (15cc?) bottle of "iso-hop extract" that Jay at Adventures in Homebrewing had given me. He had been given it as a sample. I used it in an underhopped English bitter, and it was great. It added a clean, focused hop bitterness but nothing else. (I already had good flavor and aroma). It also made an incredibly stable head. There were clots of foam in the empty glass the next morning. It was so good that I can imagine it being standard for me for part of the bittering, but, alas, Jay can't find any more. I did ask Chris at Northern Brewing since they have a similar product (Scottish) in their catalog, but he was non-committal or even a little discouraging about it. Has anyone used this particular product or another one? Jeff - -- Jeff Renner in Ann Arbor, Michigan USA, JeffRenner at comcast.net "One never knows, do one?"

Date: Fri, 12 Mar 2004 10:38:14 -0500 From: "John McGowan" <jjm1 at comcast.net> Subject: Diacetyl Reduction/Elimination I would like the Collective's opinion on the preferred method for reducing/removing diacetyl. Currently fermenting is a Pilsner with WLP800 at 52F. I have read of two methods. (BTW, if no buttery smell is detected toward the end of primary fermentation, is either of these methods necessary?) One method of which I am aware is to allow the temp to rise to approx 60F toward the end of primary fermentation for one day, then rack to secondary and reduce temp 1F/day to lagering temp. The other method is to rack to secondary (preferably a keg) and add a pint of wort kept out of the original fermentation (ie, frozen after boil, thawed, and added to secondary), allowing to ferment for 7 - 10 days then dropping 1F/day to lagering temp. Do both methods produce the same results? I'm leaning toward the second method since it would have the added advantage of giving the beer some carbonation. (BTW, if I follow this method would it be worthwhile to rack over to a clean keg after secondary and then lager for an even "cleaner" beer?) Again, which method is "best" based on your experience? Or are they "interchangeable"? Thanks, John McGowan Hopewell, New Jersey Return to table of contents

I plan on taking the >plunge into "open" fermenters, and just setting the lid on my >fermenter. I ferment ales in a ten gallon stock pot, the same one I use to heat mash and sparge water. I generally keep it covered except when it overflows (see next note), which keeps contaminants out. What I like to use is 18"/49cm wide commercial plastic food wrap. It also comes in 24"/61 cm width. When fermentation subsides, I top crop the yeast. I prefer real top croppers like WhiteLabs WLP013 London and WLP022 Essex. I wet the top sides of the fermenter with sanitizing solution and stretch the plastic wrap tight. The sanitizer makes it stick. After a short time, the CO2 pressure pushes it up in a beautiful crystal dome. Very cool looking. There is enough gas escaping that it is stable and doesn't pull off as long as the sides of the fermenter under the wrap remain wet. // On your original topic, Dean, when you made your original offer I thought to myself that you might get more takers if you had given your whole name and location. I see from your ZIP that you're in Redwood City, CA, but the more we know about one another (up to a point), the nicer it is, and especially if we are going to be sending money!

Date: Fri, 12 Mar 2004 10:51:46 -0500 From: Jeff Renner <jeffrenner at comcast.net> Subject: The Yeast that Ate Ann Arbor Brewers I brewed an imperial stout Monday and used WhiteLabs WLP013 London Ale yeast, which produces a big thick head of yeast. I pitched 10 fluid ounces (300 cc) in 10 gallons and aerated three times. The next day it was crawling out and kept this up for 12 hours. I ultimately lost a gallon of beer, despite fermenting 11 gallons in a 15.5 gallon fermenter. I have the whole story with scary photos and the Recipator recipe at http://hbd.org/aabg/stories/renner03102004.html. Hope you'll take a look.

Date: Fri, 12 Mar 2004 13:26:54 -0500 From: "Alexander Pettit" <hippahoratio at hotmail.com> Subject: RE: Gas Regulator Some folks have suggested a cleaning regimen to resolve the issue - good idea. Here's one other thing to look at: If you are working with a newer propane tank with the overfill protection valve, do you usually disconnect your tank from the regulator between uses or leave it connected? If you leave it connected you may have a similar issue to one I had with my gas grill. I was cooking on the grill and after a while realized that it was not as hot as it should be and found that the gas flow appeared to be very restricted uniformly across all burners. Was I out of gas? Nope. I shut everything down, disconnected the regulator, and waited a few minutes. Hooked everything back up and I was good to go. I don't remember the reasoning behind it all, nor why this sometimes happens with tanks that have OPD valves, but I can see sense to it. Return to table of contents

I am successfully reviving yeast that has been in my "starter bottle" since 6/7/02. I have been holding this White Labs Yeast for almost two years in the fridge and now it is up and running again. I pitched the bottle to a yeast starter earlier this week and it is bubbling away. The starter should be ready for this weekend's 5 gallon batch.

Date: Fri, 12 Mar 2004 17:15:38 -0500 From: Thom Cannell <t_cannell at compuserve.com> Subject: Welding stainless Scott McAfee asked about welding... I have to second Mike Sharp's advice as to silver brazing. Scott, it's a whole lot easier to learn to braze than MIG or TIG weld. And if you don't weld every day, the brazing process is more forgiving and easier (IMO) to remember. But they are all great fun and taught at almost every high school or junior college. Some welding shops have classes for potential buyers and will offer good advice if you bring along typical "I need to weld this to that" parts. I just added sight glasses (right angle SS tubing and braided hose) to all my kettles, and finally modified my large Polarware kettle. I added a 1/2" female coupling to replace a 3/8" male pipe. It was darn near impossible to create a good strainer in the boil kettle and now I have something that works extremely well (you'll see it eventually in BYO Magazine.) Welding (silver brazing) took maybe five minutes and another few for cleaning the flux and smoothing any roughness. BTW, ordinary hole saws will cut very nice holes in Polarware pots! When buying the silver-bearing rod, go for the highest silver content. Sure, it's more expensive, but works easier, flows better. And I'm not half done with the one stick I got two years ago. Also, the correct flux is critical. Call the techs as Harris Welco or your vendor of choice. I did write up the whole welding stainless thing in BYO a couple of years ago...

Date: Sat, 13 Mar 2004 01:25:40 -0500 From: "-S" <-s at adelphia.net> Subject: er: mixed yeast strains Robin Griller writes ..., >To follow up on Dave Burley's contribution on this, mixed yeast strains >are, of course, used by significant numbers of breweries operating today, Primarily in the UK & Belgium where pure culture never fully caught on. >And, contrary to Steve's post, they apparently can >be quite stable mixes. Bateman's brewery in England, for example, uses a >two strain culture that remains stable for about 16 brews, That's not very stable. How controlled are the brewing conditions to maintain this limited stability ? How do you think this limited stability would stand up if we changed the wort characteristics or the fermentation temps of the access to O2 ? Not well I think. >The highgate >brewery, iirc, has a four strain culture. They apparently isolated the >strains and attempted removing the less prominent strains, but had to >return to the original four strain mixture as the beer produced was just >not the same. We hear this sort of "mystical mixture of yeasts" stuff from numerous breweries. Whitbread has three which each bring something to the party, even Pilsner Urquell claims to use three strains. At least the Whitbread case was well studied. I think it's mostly advertising copy - "we have this unusual fermentation that ...makes our beer unique". UK and Belgians breweries didn't pick up the pure culture craze that Hanson started in Copenhagen and which rapidly (dis)infected Germanic breweries. Well at least not till many decades later. It's relatively easy to select out pure strains, but it's been relatively hard to reliably distinguish and match strains until genetic phenotyping became available in the past decade+. The breweries which do not use pure culture typically had no idea how many yeasts were involved nor whether the strains were in stable mixtures. There is absolutely no reason to think that the current 4 strains of Highgate are the same in number, strain or mixing proportion as what appeared there prior to pure culture maintenance. They typically wouldn't know. Please note that I am not dissing the beers made from mixed culture. The wine industry is more evenly split between "natural (mixed) fermentation" vs pure culture and it's difficult to claim superiority for either side except in specific cases. In beer natural fermentation or some of the complex successions of fermenting organisms used in some Belgian beers can be stupendous - but are of course unreproducible and have the potential to be very bad (infected). I agree with Robin's other points, except I think it may be difficult to find pairs of brewing yeasts which are "metastable" together. If you have a traditional brewery and find two strains in the fermenter in quantity you might reasonable have a metastable pair. If you pick two smack-pack and mix the results it's far less likely. You haven't selected for metastability. Perhaps if you mixed together 50 ale strains and grew these for several dozen generations and looked for prominent populations by phenotype you'd find some metastable mixes. -S Return to table of contents
Date: Sat, 13 Mar 2004 01:30:39 -0500 From: "-S" <-s at adelphia.net> Subject: Killer yeast/acetone Mike Sharp asks, >Steve mentioned killer yeasts...I've always been curious about this. What >is different about a killer yeast, and is it effective against, say wild >yeasts? Are they effective against other spoilage organisms? One K-factor is a protein secreted by killer yeasts that causes neighboring cell membranes to open a selective potassium channel. The cells can no longer maintain their ion balance and die about as quickly as a human after a potassium injection. The killer cells do not suffer the same fate since this toxin also closes the potassium channel when it's present inside the cell. Killer yeast are effective against many wild yeasts, but certainly not all. In one test 30 yeast were sensitive to the potassium channel K-factor and 59 were not impaired by it. I doubt it prevents bacterial infection which are the primary brewery spoilage vectors. Bacterial membranes are a fair bit different than fungal membranes. This "K-factor" is apparently caused by a virus infecting the yeast and the property can be introduced into uninfected yeast relatively easily. ====== Fredrick notes that some Clostridia can produce acetone. Not only Clostridia but also Saccharomyces cerevisiae have been used for industrial acetone production by this pathway ! It *shouldn't* occur at beer pH, but ... Also consider that certain esters have a very solvent-y aroma not unlike acetone. -S Return to table of contents

Since no one seemed to know, I just added 3 teaspoons into the 5.5 gal, and it took 4 days, but it's really taken off. The output of the bubbler smells fine, so I guess it's the yeast, not bacteria that's chomping away. Dave King (BIER) [396.1, 89.1] Apparent Rennerian Return to table of contents
