---------------------------------------------------------------------- Date: Thu, 01 Jul 2004 22:40:13 -0400 From: Thom Cannell <t_cannell at compuserve.com> Subject: How long to use yeast? Dave Glowacki asks: How long is too long to keep yeast (White Labs vials) in the fridge before it is too old to use for brewing? I had some White lab hefe yeast from - - the Michigan national HB convention. Like two years old? In a 150 ml starter, it took almost a week to grow. Made two great batches with it so far. Guess that old "if there is one surviving yeast cell..." is true. Thom Cannell Lansing MI Return to table of contents
Date: Fri, 2 Jul 2004 20:08:44 +1000 From: "Graham L Sanders" <craftbrewer at bigpond.com> Subject: What A Difference A few Months Make Oh dear, typing my latest HBD post and I sent the previous one elsewhere. Enjoy G'Day All You just got to hate doctors, in fact any medical staff. They prod and poke you, (happily these days with my pants on), and then say, yep you are better. Never mind it feels like there is a squash ball under one shoulder blade, and I got a bit of a pain at the top of my chest. "dont worry Graham, everything looks fine from where I sit." and then your flicked out of there office. You just feel like sending them to a Iraq prison to see "insensitivity". But one does feel better doing yet another radio program. I was rusty, and things didn't quite click, but it was good getting back into a routine. Those who read the BYO magazine will be interested that the May program is on the website, and I interview Phillipa Jarrott (who appeared in the mag), who I call our "Bush Brewing Babe". Unlike Phil, who is pseudo USA urban cowboy, Phillipa is a true blue dinky die bush brewer. I have bets no-one brews like her. Junes Program has an interview with a local microbrew brewer, so those interested to see how you can enter the business, can listen to guy who got in without qualifications, but thru shear love of the hobby. Also those interested in a style of beer, the Australian Sparling Ale, should also check January, February programs, where I give a history of the style. Interesting my research indicates its this style that may have lead to the USA style "Steam Beer". Trust you lot to take one of our styles and make it your own. And if its not bad enough this program is on the net, well it could be farmed out to other radio stations. People are approaching me about running the same program nation wide. Scary stuff, especially those who have seen me. But where to find the program. oz.craftbrewer.org Now Lets have words with young Mr Hurst. >>>>After a couple weeks I started getting the shakes and eventually began reading the Oz Craftbrewer list in an attempt to get the monkey off my back. This was little help as most of the discussions there seem to be about Salties and Graham Sanders.<<<<<<< Now I have to say I'm a little embarrassed lately. The tourists are getting taken, but the locals are. Incidents were coming in fast of locals bitten, dragged in and crocs trying to jump into boats. One poor bloke was castnetting on a popular swimming beach early morning and threw the cast net right over one. Probably saved his life, as it was moving it fast for the kill. Needless to say, no cast net, and his arm nicely pulled out of its socket. I guess its a case of small things amuse small minds. After all it was only 10 feet long, a baby. Shout Graham Sanders oh The software available today for editing things like radio program is damn dangerous. Its soooo easy to use, you can change anything, even change what some-one says by splicing in words. And you can make it seamless. Real scary stuff. I called George Bush and told him I could put a positive spin on all those "naked guys". He hung up on me when I suggested I could change the reports to say they were trying to save money by doing a bulk prostate examination. Mind you, I would have no complaints if that girl in the photos did it. I just wouldn't take her home to mum. Return to table of contents

Date: Fri, 2 Jul 2004 06:56:22 -0700 (PDT) From: Calvin Perilloux <calvinperilloux at yahoo.com> Subject: Doh, Kelvin math botch (Cold CO2 tanks) Doh! From my last post on CO2 tanks in the fridge: Now that's what I get for trying to think in English and metric at the same time: "Per Charles Law, 343 kelvin/373 Kelvin * 12 litres" That was from my last post, detailing the pressure diff between room temp CO2 and refrigerator CO2. What was I thinking? Where on earth did I get those numbers? Brains lapse. Doh! Boiling my beer??? Should be: "Per Charles Law, 273 kelvin/298 Kelvin * 12 litres" The end result, as some of my college professors would have pointed out in the exam grading, is still pretty close, but negative points for sloppiness! Sorry. Should have put this one up for peer review, eh? Calvin Perilloux Middletown, Maryland, USA Return to table of contents
Date: Fri, 02 Jul 2004 10:20:25 -0400 From: Paul Shick <shick at jcu.edu> Subject: RE: Help with false bottom Hi all, Pat Reddy asks for help with finding a replacement for his collapsing false bottom in his converted keg mash tun. Pat, you can probably get away without replacing the false bottom if you rig up an appropriate support for the center. Some people have used stainless steel screws and bolts. My fix was even easier: take a 1.5" diameter copper tube, exactly as long as the distance from the center of the false bottom to the bottom of the keg. The tube will fit around the pickup tube, supporting the FB. You'll need to cut some slots in the bottom of the tube to let the wort flow to the pickup tube. So to set up the mash tun, just drop in the copper support tube, slotted side down; put in the false bottom and drain tube, and you're all set. I've used this with my setup for about 7 years, after suffering through several collapses of a hinged false bottom. It's worked perfectly since. Hope this helps. Let me join the chorus of HBDers thanking Pat for resurrecting our favorite part of cyberbrewing from the ashes. Well done! Paul Shick Cleveland Hts, Ohio Return to table of contents
Date: Fri, 2 Jul 2004 07:28:08 -0700 (PDT) From: Calvin Perilloux <calvinperilloux at yahoo.com> Subject: Aged yeast Dave Glowacki asks about using White Labs yeast that's been in the fridge since early April. No problem, Dave, as long as you use a starter. I've used White Labs yeast that's been much older than that, but I'd never pitch it straight into the fermenter. Build one liter starter first, and then you can even give a smell and taste to the result to make sure it's good before pitching it. By the way, what's the best yeast product for longevity? My vote, based on years of use, is for the old-style Wyeast smack-packs! Seriously. I've been able to build some of those up with no ill effects after they've sat more then 2 years in the fridge.

Date: Fri, 2 Jul 2004 15:47:43 -0400 From: "-S" <-s at adelphia.net> Subject: re: Question about yeast David Glowacki asks ... > I have a quick question, and hopefully will get a quick answer: > How long is too long to keep yeast (White Labs vials) in the fridge > before it is too old to use for brewing? I've had some since early April > - too long? The quick and useless answer is MAYBE. RTP yeast vendors stamp use-by dates on their product that imply a 3-6 month useful life, but I think this is highly optomistic. You'll probably get a tolerable ferment w/ a 3 month old RTP, but I wouldn't bet a batch of wort on it. If kept in cool conditions that older RTP should make a fast & vigorous starter pitching, and you can then pitch the starter into the whole batch. I can (and have) argued that RTPs even under best conditions do not have enough viable cells for an ideal 5gal fermentation. My limited experience is that the RTPs make a nice ale where the modest underpitching flavors aren't out of place, but are too little for lagers. I prefer higher pitching levels for both. -S Return to table of contents
Date: Fri, 02 Jul 2004 15:08:26 -0500 From: Michael Owings <mikey at swampgas.com> Subject: re:AHA Big Brew Baltic Porter Fermentation Fred notes regarding WYeast 2278 ================================== "I suppose I've learned that 50 F is a little too low for this yeast, but I'm more interested in understanding the reason for the 57-62 F period for four weeks." I've used this yeast on a number of beers down to 44-46F, with no problems. Having said that, I've used it only on beers up to 1.065 -- nothing quite as high as the baltic porter. I _have_ used Whitelabs WLP802, however, down to 42F on doppelbocks (up to around 1.085) -- does anyone know if this is the same yeast as WYeast 2278? In either case, I'd be surprised if the 50F fermentation temp alone was really the problem .

Date: Sun, 4 Jul 2004 08:33:35 -0400 From: "May, Jeff" <Jeff.May at uscellular.com> Subject: Vigorous aeration and finishing hops I originally posted this about the time the HBD went kaput. Now that everyone is back on line, here it is again. I have recently started aerating my wort with a SS air stone during pitching. I am now achieving the lowest FG I have ever experienced! Needless to say, I'm hooked. However, I'm concerned that vigorous aeration could drive off most or all of the precious flavor and aroma from my finishing hops. Dave Miller talks about how aeration can be effective in floating off a large portion of the cold break material. The foamy scum is then skimmed off. [Miller,Dave:Dave Miller's Homebrewing Guide; Storey Books; 1995 Pg.181]. I just wonder if this action is scrubbing the volatile hop oils as well.
