---------------------------------------------------------------------- Date: Thu, 22 Dec 2005 23:06:38 -0800 From: "MICHAEL HOBART" <M-HOBART at msn.com> Subject: Renewed Fermentation Good Day Beer Lovers, I have a Russian Imperial Stout that I have been bulk aging for 13 months. 3 days prior to my planned bottling date I added White Labs Champagne yeast (which I have done with a previous Barley Wine and 2 stong Belgian ales with good success) only to find after 2 days I had a thin foam layer on top of the beer and bubbles in the airlock every 8 seconds. My O.G. was 1.099 and had settled at 1.012 (lower than the projected 1.020) then after 2 days was down to 1.010. Not wanting it to dry out anymore and fear of bottle bombs I racked it into a corny keg and placed it in an outdoor shed where the temp was ranging between 27-33 degrees to deactivate the yeast. After 5 days of freezing weather the temp is starting to rise and so are my fears of the fermentation starting again. Was 5 days of freezing temps enough to permantly stop the yeast or as temp goes up will they just take up where they left off? Is there anything else I can do that won't adversely affect the beer? Thank You in advance for any advice given. Mike Hobart Portland,OR Return to table of contents

Date: Fri, 23 Dec 2005 06:58:57 -0800 (PST) From: Paul Waters <pwaters3 at yahoo.com> Subject: Re: Duvel Clone incremented feeding Kevin I to am planning on brewing a Belgian Golden ale. My planned grain bill 9lbs Pilsner Malt 2lbs Carapils Malt .5lbs Aromatic Malt 1lbs Belgian Candi Sugar Clear (may up another 1/2 pound) 1 Belgian Strong Ale Yeast 1388-XL Activator With Styrian Golding Hops with a double decoction mash After reading your post I googled Duvel and got this link Http://www.duvelusa.com/beer.php?cat=brewing Interesting reading! The mashing is a 4hr process, which is what it usually takes me to do a double decoction. I don't see that much of increase in darkening/caramelizing by decoction mashing. Though my grain bill will make it slightly darker, less then 1 SRM point. The interesting part on the website is Duvel started with a Scottish yeast and they ferment 62'F - 82'F. This is the part that really makes me ponder on the technique. The banana character, at least to my understanding with wheat beers can be increased by under pitching and having long lag times. I also wonder if its a fixed temp ferment or do they start high then droop or start cool and go up. Which method would increase the ester production? Hopefully we can get some feedback on the fermentation to help reach the banana and ester products without over doing it or under doing it.

Really ? I intend to be didactic - to explain things in enough detail so someone without specialized knowledge can follow along. I suspect it seems pedantic if you lack curiosity about the topic, but that's more a reflection on the reader than the poster. >The HBD Discussion forum would seem to be a much better place for >esoteric discussions [...] In other words, people who actually find >it interesting. Any topic will only engage a fraction of the audience. If measuring the course of fermentation isn't of general interest on HBD then it's unlikely anything will be. To get beyond current practice in measurement we must discuss minutiae - but how exactly does this harm anyone ? I understand that not everyone is personally interested in pushing the limits of HB instrumentation, but certainly it should be met with curiosity and interest rather than banished to some other forum. Common HBD discussions of wort cooling, oxygenation, yeast selection and basic sanitation would seem pointless and esoteric to most 18th century brewers since they couldn't understand the practical importance of these things. The line between "esoteric" and "useful" discussions is determined by the readers understanding and curiosity as well at the topic material. Lack of understanding is often correctable, lack of curiosity is not. - -- On DarrellL's Einstein quote .... No offense taken or intended Darrell, but I don't understand the relevance. I'd contend that to a brewer fermentation progress 'can be counted' and does 'count'. I'm just looking for a better 'count'.

Date: Fri, 23 Dec 2005 19:00:16 -0500 From: Ken Pendergrass <kenp794 at comcast.net> Subject: brewing software Merry Christmas, Is there a brewing software program, preferably for OS X, which will allow one to enter the amounts of grain and adjuncts for a mash in % and will calculate the actual amount required of each ingredient to make a specified quantity of wort? While were at it perhaps it could calculate for color, utilization, carbonization, the whole nine yards, and recalculate each as I adjust quantities of one or more ingredient. And if not for Mac then how about, shudder, for Windows? Thanks, Ken Return to table of contents
Date: Fri, 23 Dec 2005 20:27:43 -0500 From: "John Bryce" <jbryce at vt.edu> Subject: yeast starter problem I recently made 2 liters of wort from extra light DME to be used as starters. I had only done this once before, years ago. I heated up my water to maybe 150 F and then started adding and mixing in the DME. I predicted that I would need something like 6 ounces to get to 10-11 P (1.040-1.044 SG). I took a gravity reading after I mixed in the 6 ounces thoroughly and it was low, so I added more DME and re-sampled a few times until I got to about 10.5 P. I boiled it for about 6 minutes, cooled it to 50 F rapidly, and then poured equal parts into 2 separate growlers. This gave me 2 half gallon growlers that were each half full (1 liter). I pitched a white labs vial of lager yeast into one and some lager yeast that I had recently harvested into the other. I shook both of them up to aerate and put them in ambient temp of ~54 F. I saw no visible activity in the harvested yeast starter. I started taking gravity readings after 2 days to see what the hell was going on and I got 7.4 P. The yeast sedimented out and the wort was bright and flat. I moved everything to ambient temperature of mid 60's. Same thing days later. I saw very slight activity (a few large bubbles on the surface) in the starter from the vial on day 2. Gravity was 7.6 P then and now. There was some carbonation present and there was some yeast in suspension. The carbonation dissipated and the yeast dropped out around day 4. Currently I have only one theory as to what happened: There is a reasonable chance that the yeast (both strains had been stored in the same fridge) froze. It was not frozen when I pitched it, however I had never seen it stick to the vial's walls/bottom that much before. The fridge had been set colder than it should have. The cheap thermometer that I have in there read 30 F when I pulled out the yeast. I guess there is also a remote chance that I screwed up the wort and it ended up being really high gravity, but I think that is a long shot since I took multiple readings with a commercial brewery hydrometer that I know is good and only boiled it for ~6 minutes after my last reading. Any other theories or tips? I'm going to try again with new yeast next week. I hit my local homebrew listserv before this one, and one guy had this to say: "I have had two extract beers finish extra high: 1.076 to 1.040 and 1.079 to 1.043. I was using extra light DME from the same supplier. I added two tablets of Beano to each carboy. Both of these beers continued to drop pass 1.025. This implies that the malt extract had a large amount of unfermentables in it. (Before I added Beano to one of the beers, I created a new starter and added it - no fermentation. With Beano, fermentation occurred.)" Thanks for any info. -jb Return to table of contents
