That was with a pale ale using all grain. I have left the second stage of fermentation for 2 months at about 15 degres Celcius (59F). The yeast was an ale variety from Edme. Primary fermentation has been quite active for 2 days then drop sharply. Secondary fermentation was always very slow. A relative density of 1.010 seemed high but I decided to bottle anyway. Two weeks after bottling, carbonation was already quite high, but seems to have stabilized after 4 weeks. Later, I brew a similar batch (with flaked corn) that shows a similar fermentation pattern until the temperature in the appartment rose to about 23 C (73F). During the 2 months period of stage 2 fermentation at 15 C, only 1 bubble every 2 minutes was visible. But when temperature rose to 23 C, bubbles began to shows in great numbers. I think that even after 2 months, my batch of "almost Old Faithfull" has been bottled but has not yet finished fermentation because of chilly yeast. The second batch is not yet ready to bottle. A batch made with malt extract using exactly the same kind of yeast don't shows such a strange behavior. Next time, I think I will try to change yeast brand or variety (lager yeast to make ale?). I dont't think contamination is the cause. Return to table of contents

Date: Tue, 6 Jun 89 08:36:17 mdt From: Jason Goldman <hp-lsd!jdg> Subject: Lager vs Steam:an experiment Full-Name: Jason Goldman I've just recently conducted an interesting experiment. My most recent batch of beer is a lager (J's Bock Cantata), the first I have tried. My basement, at the time of fermentation, stayed around 55 degrees, so that went fine. When it came time to bottle, things were warming up, so I fit a case and a half into my bar refrigerator so I could lager the brew at 40 degrees. The remainder I let age at room temperature (65 - 75 degrees). This worked out well for providing a comparison between lager and steam beers. The lager was significantly smoother than the steam (tho both are tasty). The only thing that I regret is that I underprimed the batch and it is not as carbonated as I like (I don't want a geyser, but I like to get a little head ;-).

Well as it turns out I've been using Red Star in nearly all ... >the final product. To get to the point of all this, what are people's >preferences in types of yeast? At this point I'm mostly interested in I have used Red Star in about 20 batches of ales and once in a steam beer. I have no complaints about it. The brews have all had good aroma (ie nothing moldy or wierd smelling). Red Star gets going fast, which I like. I've read in a Steinbart's newsletter that Red Star ale yeast has a relatively high concentration of bacteria and wild yeasts. This apparently hasn't presented a problem for me. I plan to continue to use it for the convenience it affords me. He goes on to inquire: >I have bought and read Papazian's book on home brewing. I also have >David Line's book, Brewing_Beers_Like_Those_You_Buy (mainly because it >has a recipe for John Courage). The question is what is a good book that >takes up where Papazian's book left off? I highly recommend Miller's book "The Complete Handbook of Home Brewing". I believe it is a more serious and scientific approach to homebrewing than Papazain's book (although the recipes and tips in Papazain's book are really great). David also asks: >trying to copy (since saccharin doesn't ferment). I haven't actually tried >any of his recipes that include saccharin yet. Does anybody have any >suggestions on how to control the sweetness of the final brew? A fellow at Steinbart's suggested I use lactose, which is supposed to not ferment by yeast. I bought some but haven't tried it yet. Saccharin sounds like it would work because the bitterness could be masked by the hops. I will never use it, since I am a health nut.

Certainly there could be other factors, but in my experience, yeast quality is a very important flavor consideration. I have had universally good luck with Doric, Leigh&Williams, and Edme. Wyeast liquid lager yeast has worked marvellously the one time I used it (but watch out - see below...) Some kits provide wickedly pleasant yeasts - Dogbolter in particularly has one of the sweetest-smelling yeasts around. Try an A-B comparison, substituting Doric for Red Star. When I did that I gave up Red Star forever. David Sheehy also writes: > My taste in beer runs towards the sweeter varieties. I have been unable to > duplicate the sweetness of the beer at the microbreweries I've frequented. I have found that adding healthy quantities of crystal malt can have a nice sweetening effect on amber ales, though I haven't got a lot of scientific evidence to back this up.

The worst-smelling fermentation I ever achieved was with Wyeast liquid lager yeast, which produced a beautiful-tasting lager.

Date: Tue, 6 Jun 89 18:06:12 PDT From: polstra!jdp at hplabs.HP.COM (John D. Polstra) Subject: Re: specific gravity measurement problem In Digest #166, Martha Garske explained how to adjust an S.G. reading to account for more water that has been added: > Since water has an S.G. > of 1.000 ( it is, in fact, the reference for the specific gravity scale) > multiplying the S.G. obtained for the 2 gallons by 0.4 is exactly the > correction needed for the S.G. of the 5 gallon batch. I'd like to add a small clarification to this, just in case it's not obvious to everybody. You have to subtract out the 1.000 from the S.G. reading first, then multiply by 0.4 (or whatever the ratio of volumes is), then add the 1.000 back in. So, for example, if the measured S.G. of the 2 gallons was 1.100, you would multiply 0.100 by 0.4 to get 0.040, yielding a corrected S.G. of 1.040. If any of you have doubts about this, consider the case where it's all water: the original and corrected S.G. readings should both be 1.000. -- John Polstra jdp at polstra.UUCP Polstra & Co., Inc. ...{uunet,sun}!practic!polstra!jdp Seattle, WA (206) 932-6482 Return to table of contents
