Date: Fri, 08 Nov 2002 08:40:06 -0500 From: "Sven Pfitt" <the_gimp98 at hotmail.com> Subject: Yeast and O2 The recent discussions on yeast pitching rates and O2 concentration has me wondering if it is possible to over-oxigenate a starter. I'm trying to configure a system for the ultimate in 'big healthy yeast starters'. I recently configured a 2L flask on a stir plate with a two hole stopper. One stopper has a hose to the bottom of the flask with an air stone on it. Air is provided from an aquarium pump. Since this produces lots of foam when the air pump is running and the stir plate is running. I connected a blowoff tube from the second hole in the stopper through a lid in a 1qt mason jar. The tube is submerged in a pint of water. A second hole in the mason jar has a stopper with an airlock. When running there is lots of foam that gets pumped into the econd vessle which is a water filter. Since this foam contains yeast, it ends up settling in the second container. So, basically this is a continuous yeast skimming operation with continuous air bubbled through the wort. In 48 Hrs it has produced about 3/8 of a cup of yeast in the collector vessel, from a 1L starter in the primary vessel. There is a picture of the setup when I started it running at: http://www.thegimp.8k.com/images/pb060002.jpg Good healthy Yeast? I won't know till I try using it on a batch of beer. Comments?

Date: Fri, 8 Nov 2002 09:00:44 -0500 From: "John Misrahi" <lmoukhin at sprint.ca> Subject: Cider Update Well, I think the Coopers ale yeast i had pitched in my cider was a bit too old...I waited and waited..and pitched 2 packets of lalvin Ec-1118 champagne yeast. it took off and has quite a big krausen for cider, the airlock is bubbling every second or 2. I used only the juice with some nutrient and the yeast, but i am thinking of adding some sugar to make it a bit stronger as an afterthought. I have 2 ideas. One is to make a sugar solution and add it to the secondary, then rack the cider onto it. THe other is to add it directly to the primary. I have some liquid cane sugar i got one at a specialty food store and since the bottle is still sealed it should be sterile (i think) . I might use that. Also, i've used EC-1118 once before for cider, last fall. We made 50L of cider from freshly pressed juice. Just juice, cider and nutrients. To one bucket we added some frozen raspberries (i dont have the amount handy, but it wasnt enough!). The cider is great. We put most in champagne bottles. It is super dry but retains some good apple flavour, though people either like it or hate it. The latter becuase its 'not sweet enough'. Boo hoo hoo, more for me! :-) John Montreal, Canada Pothole? Thats luxury! I have to ferment directly in my mouth. On brew day I fill up my mouth with wort in the am and drop a few yeast cells in and 3 hours later I swallow. Wish I had a pothole to ferment in. -Mike Brennan on the HBD "Ah, Billy Beer... we elected the wrong Carter." -Homer Simpson Return to table of contents
Date: Fri, 08 Nov 2002 09:08:50 -0500 From: Marc Sedam <marc_sedam at unc.edu> Subject: speise Mauricio from Argentina wants to talk about speise... As with most good HBD replies, I won't quite directly answer your question. At some point in the past I tried to figure out this exact question and ran through the calculations (which are actually not that hard). The answer I kept coming up with was that adding two quarts of a "normal" OG wort (1.040-1.060) will get you the carbonation you're looking for. If you're making a giant beer (OG>1.090) you can use just one quart. The difference in carbonation between two quarts of 1.040 priming wort and 1.060 priming wort is barely noticeable. I know I couldn't tell the difference between a beer with 1.7vol/CO2 and one with 2.0vol/CO2. Like I said, it's neither exact nor scientific but it works fine. In fact I just primed a pony keg of CAP (Renner...it's my best one yet) and a corny of Schwarzbier with this method and they both carbonated perfectly. Two days at room temp after addition of wort and...badda bing...perfectly carbonated brews. Hope this helps. Cheers! Marc "Cerevesaris felicitus" Return to table of contents

Well, there is a problem here. The 71.4% is apparent attenuation, not real attenuation. The specific gravity of the finished beer is pulled down by the alcohol, which has a specific gravity of 0.8. Fortunately, you can calculate the real attenuation. More about this in a moment. >It uses OG as the main variable. But I can have 2 diferents worts with the >same OG but diferent fermentability due to different composition of the wort, >different proportions of glucose, maltose, maltotriose and dextrins. >Also I know 3.7 grams of glucose produce 1 vol CO2, but How many grams of >maltose produce 1 vol of CO2? And the same for maltotriose and other >fermentables I get in the wort. One gram of any of these sugars produces 0.46 gram CO2, or close enough to 1/2 as much CO2 as sugar. Warner's books have convinced me that grams of CO2 per 100 ml beer (% CO2 by weight) is a much better way (IMO) of specifying carbonation than volumes. The advantage is that you don't have to worry about under what conditions is the volume of CO2 specified. The typical German lager has 2.3 volumes of CO2 or 0.45% by weight. But don't forget to include the amount of CO2 that is dissolved in your beer before adding the speise. Warner covers this as well as calculations for adding speise. >I know Eric Warner explains the Kraeusening method in his Book "German Style >Wheat Beers", but I can't get it here and due to Argentine economical >situation is hard now for me to buy it from Amazon.com. We brewers have to watch out for one another. I've scanned and sent you separately the four relevant pages from Warner's book. I hope they help. BTW, adding unfermented wort, or speise, is somewhat different from actual kraeusening, in which newly fermenting beer/wort at high kraeusen (kraeusenbier) is added to the finished beer. This not only carbonates the beer but cleans up unwanted fermentation products, most notably diacetyl. It is also reputed to have other advantages such as longer lasting head and greater resistance to oxidation.

Date: Fri, 08 Nov 2002 11:06:16 -0500 From: Jeff Renner <JeffRenner at comcast.net> Subject: CAP for extract brewers Brewers I opened my new Williams Brewing catalog yesterday and was very pleased to see that they have two pre-pro kits made with extract mashed with 30% flaked corn, Old American Ale and Old American Lager (see http://www.williamsbrewing.com/). While I'd like to see them hopped at a higher level (they are 23 and 21 IBUs respectively), that is a simple matter to remedy. They also have the malt extract itself, which they used to carry some years ago. This means that Classic American Pilsners (CAP) are easily in the reach of all extract brewers. Perhaps the most often question I get asked by brewers who have read my articles in Brewing Techniques and Zymurgy is "How can I brew this if I don't do all grain?" I've always had to suggest the poor alternative of rice extract or a mini-mash with flaked corn, which is nearly as much trouble as all-grain. While I haven't used these kits, I used to use William's extracts back in the 80s before I became an exclusively all-grain brewer, and have brewed their kits more recently with several beginning brewers. I have found them to be of excellent quality. I like the fact that their extracts are not canned and are very fresh. I think if I were to make an all extract CAP. I might opt for a little less than 30% corn. I use 22% in my all-grain brews, and you can hit this exactly by buying a 6 pound pouch of the American lager extract (30% corn) and one of American light (all two-row). Then use all of the malt/corn pouch and 2 lbs of the all malt extract, and freeze the remaining four pounds to preserve freshness to use later. Then, I'd suggest using enough Cluster hops for authenticity (don't know what is in the kit but Williams doesn't carry Cluster) to bitter to ~30 IBUs, and Saaz or Hallertauer or new American equivalent hybrid (Ultra, Crystal, Mt. Hood, etc) for flavor and aroma, to get ~35 IBU total. You could even do a first wort hopping by dissolving the extract to get 5.5 gallons or so, then steep your late addition hops at ~170F for 30-60 minutes before proceeding with the boil. The ale kit might be great as is for a more or less modern Canadian ale (well, 1960's), or with more hopping and less corn for a Classic American cream Ale (CACA) If anyone tries these products, please let me know. - -- Jeff Renner in Ann Arbor, Michigan USA, JeffRenner at comcast.net "One never knows, do one?"

Date: Fri, 08 Nov 2002 11:23:29 -0500 From: Bill Wible <bill at brewbyyou.net> Subject: Malt vinegar? I'm currently trying to make malt vinegar. The instructions say to add the mother to finished beer, and you have to leave the culture uncovered because air is needed for conversion, and you have to put it in a warm place. I added 2 mother of malt vinegars (I used 2 because they were pretty old) to 4 different old bottles of beer I had lying about - 2 cans of Schaeffer, a Ruddle's County, and a bottle of Ommegang, which is belgian beer. This should make for a pretty decent vinegar. Anyway, I mixed all this in a clean and sanitized gallon jug and sat the thing on top of my fridge. It's been about 3 weeks. What does a "mother culture" look like? At this point, I have a large, white, flat pancake looking thing that takes up the entire surface of the liquid floating just under the surface. It kind of looks like a coffee filter pad, but thicker. It's white, flat, smooth, and very even. I swirled the liquid, and it sank. I'll check tonight whether its floating again or not. Nothing in the cultures I added looked like that, which is why I'm wondering. The cultures I added had small, loose particles, and they were grey-ish, not white like this thing. I'm just curious whether this seems normal, or if anybody who has any experience with what this thing should look like can tell me, etc. Thanks Bill Return to table of contents
Date: Fri, 8 Nov 2002 10:26:10 -0800 From: "Kent Porter" <kporter at well.com> Subject: Christmas Ale Recipe Don Scholl asked for a good Norwegian Christmas/Holiday Ale. I made this one for last year's holiday season: http://www.byo.com/recipe/210.html I substituted 1 tsp good quality vanilla extract (I did not have vanilla bean). In addition to the spices called for in the recipe, I used 0.5 tsp whole cloves, and 1 tsp cinnamon, steeped while cooling. I also put in ~100 g. candied ginger (chopped) for 15 min of the boil. OG 1.060 FG 1.012 The result was very good after 4 weeks in the bottle. Kent Porter Omaha, Nebraska Return to table of contents
Date: Fri, 08 Nov 2002 13:45:51 -0500 From: Randy Ricchi <rricchi at houghton.k12.mi.us> Subject: lager yeast types The other day I mentioned I was trying to find an article I once read about lager yeasts being being seperated into two categories. Well I found it (although I don't have it right in front of me as I type this) The article was by Ray Daniels and was in an issue of Zymurgy devoted mostly to lagers. I believe he was saying that one class of lager yeasts (carsberg-type) was sulfur producing, and the other (tuborg) was estery. He gave only one example of the tuborg type, Wyeast 2007. Examples he gave for carlsberg yeasts were Wyeast 2206,2308,2214, among others. Interestingly, George Fix in "Analysis of brewing techniques" broke lager yeasts out into two categories, which he distinguished as "malty", and (I think) "dry/crisp" . Some of the examples George gave for the "malty" yeasts were the same ones Ray gave for the "sulfury" yeasts. I believe Wyeast 2007, which Ray classified as estery, was one of the examples George gave for "dry/crisp". It is an interesting subject. I'm not crazy about sulfur in my beer, but I have noticed that many of the strains that throw sulfur end up with a nice malt character after the sulfur is reduced. I recall reading in Brewing Techniques somewhere that it was thought by some that lagers with all sulfur character removed were somewhat insipid. In my experience it takes 6 to 8 weeks of cold storage (46F or so) before the sulfur levels were mostly reduced and I could enjoy my beers. This is why I have an interest in lager yeasts that aren't as sulfury. I'm thinking maybe beers produced with estery yeasts may require less lagering time before they taste good. If I was a patient man I may have taken up winemaking as a hobby :^) I think it was George Fix's description of the non-sulfury yeasts as producing "dry" beers that scared me away from trying them. Maybe I shouldn't put so much stock in a one-word description. If the Wyeast 2007 yeast is the "St. Louis" strain, I used it one time a few years ago to make a very light American style pilsener. It had the apple-ester, and was a very nice beer. I don't recall if there was a long waiting (lagering) period for that beer. Perhaps I should experiment with some of the other "estery" lager yeasts. I used to think that one sign of a good lager was that there were no esters. To me, estery meant ale-like, and lager beer meant no esters. Lately, I've been re-thinking that. Obviously, we wouldn't want a lager with the ester character of an English ale, but I believe some subtle ester character is needed for a beer to taste "beery". Perhaps the HBD community would be interested in sharing their experiences with the various lager yeasts available to us. Sulfury? Estery? Dry? Malty? Long lagering times needed, or short? For those of us in the US of A, it's a timely subject, since winter is just about here. Return to table of contents
Date: Fri, 8 Nov 2002 14:32:01 -0500 From: "Steve Alexander" <steve-alexander at worldnet.att.net> Subject: Re: Potassium Sorbate in Cider Michael Grice writes ... >>I started a batch of cider yesterday with a blend of store bought >>ciders. [...] >> I pitched a few packets of Coopers ale yeast. Today, there is >no activity. Zero. I suspect there may have been Potassium sorbate or >>[...] >I'd add yeast nutrient and aerate some more. If that doesn't help, try >adding a more aggressive yeast. [...]. That would be good advice if this was a stuck fermentation, but it isn't. It's not a fermentation at all. I agree with the original poster that something - perhaps a sorbic acid salt has been added as a preservative. Sorbic acid is not toxic to yeast, but does prevent them from fermenting sugars. Sorbic acid is used in winemaking to prevent complete attenuation. If it's sorbate you can't easily remove it but you may be able to dilute it with unspiked cider. Best probably to consider it a failed attempt. Sorbic acid does not inhibit bacteria like the E.coli of recent news scares so it's just there to increase shelf life. For fermentation use cider (apple juice for the non-NA set) direct from orchards or ones clearly labeled 'no preservatives added'. FWIW I think pasteurization damages the cider flavor very badly in "store bought" ciders. Local orchards are the only source of the real thing - no preservatives, no pasteurization - and even then you have to ask. -S Return to table of contents
