---------------------------------------------------------------------- Date: Thu, 08 Mar 2007 01:04:04 -0500 From: "Peter A. Ensminger" <ensmingr at twcny.rr.com> Subject: doppelbock: roasty vs. toasty Many responses to my request for a suggested malt bill for an upcoming doppelbock. According to BJCP, a doppelbock should be "toasty", but not "roasty". What exactly is the difference between roasty and toasty? See: http://www.bjcp.org/styles04/Category5.html Cheers! Peter A.

Date: Thu, 8 Mar 2007 07:39:03 -0500 From: "Alex Bradstreet" <abconsulting at hotmail.com> Subject: A good starting point Thank you John Peed for your remarks regarding scorching your barley. The line "the beer was said to have a soy sauce character" made me laugh out loud. I have wondered where is the most efficient starting point for the home brewer (grow the grains? make your own extract from malted barley? use extracts?) as my overall goal is to make organic, great tasting beer. I think that making your own extract might be less costly than using extracts from a bag or can, but that adds a few hours to your process. Thoughts? I've got a small batch of oganic "Toasty Brew" from extracts in the works, and if it comes out well I'll post the recipe on my website.

Date: Thu, 08 Mar 2007 08:49:20 -0500 From: FLJohnson52 at nc.rr.com Subject: Wash-Off Labels There has been some recent discussion on how to make bottle labels that are easy to remove. I just received a catalog from Diversified Biotech in Boston, Massachusettes advertising lots of novel products, one of which is a wash-off label. From the picture and description, these look much like a standard Laser-printable (perhaps also ink-jet printable?), Avery style label. They are advertised to "dissolve under running water in less than 30 seconds". I suspect just soaking the label briefly would allow one to rub it off with no trouble. It is described as 100% biodegradable. Labels come as Cat No. WASH-1000 Color White 2.625" x 1", 750/pk for $65.00 and Cat No. WASH-2000 Color White 4" x 1" 500/pk for $65.00 You can check them out at www.divbio.com Fred L Johnson Apex, North Carolina, USA Return to table of contents

I ask in that I wish > to re-use > the yeast just by pitching on top of the cake, but cannot do so for > several > days, and my lager has sat for 2 days at around 60F. I don't see any problem with that, as long as the diacetyl is completely gone and fermentation is nearly over. But before doing a diacetyl rest, I always encourage brewers to be sure they need it by smelling and tasting the nearly finished beer. I never do one and I am really sensitive to diacetyl. It depends on the yeast selection and fermentation procedure. I use WLP838 Southern German Lager Yeast (Ayinger) almost exclusively and chill and pitch to as close to 48F (9C) as possible, which is the temperature I ferment at. no diacetyl whatsoever. Some strains produce a fair amount under some conditions. Jeff - --- Jeff Renner in Ann Arbor, Michigan USA, jsrennerATumichDOTedu "One never knows, do one?"

Date: Thu, 8 Mar 2007 06:40:58 -0800 (PST) From: Matt <baumssl27 at yahoo.com> Subject: wine yeast/crimped copper chillers Raj, can we hear some more about this wine yeast? Why do you use it? - -- No good temperature measurements yet, but in messing around with the completed "crimped copper" counterflow chiller, it seems to be very much more efficient than the uncrimped version.

Date: Thu, 8 Mar 2007 09:53:44 -0500 From: Jeff Renner <jsrenner at umich.edu> Subject: Re: Malt flavor & aroma John Peed wrote from Oak Ridge, TN: > I have attempted 3 Doppelbocks, a Dunkel > and a couple of Alts - all have been disappointing in malt flavor & > aroma. The last straw was a 100% Alt that had all the malt character > of, say, Coca Cola. I actually threw it out without even carbonating > it. I have one rule about bad or disappointing beers - I don't throw them out until they are old and bad. Your beer might have been nice, if not what you wanted, once it was carbonated and had settled down with some maturation. But disregarding that, I have had good luck with a couple of tricks in brewing malty Dunkles, which should apply to Doppelbocks. First, I use mostly or nearly all dark Munich. Then I do a pseudo- decoction, which I have described previously. I think this was suggested by one of our Austrian members, whose name escapes me just now. It is much easier than a decoction and give much the same flavor results. For this, I mash about a third of the grains as usual at ~153F/67C for 30 minutes, then boil them for 30-45 minutes, then return them to the rest of the grains, which I have mashed while the first was boiling. This is rather like a traditional American cereal mash. The main mash rests at about 146F (63C) for perhaps 30-45 minutes, then when the boiled mash is added, the temperature goes to about 158F/70C. I rest it there for another 30 minutes or so, then mash out and lauter. Most recently, I have even pressure cooked the small mash (as I do with cereal mashes for CAPs). I put the pot with the mashed grain in a big 22 qt (21L) pressure cooker so that I am not applying heat directly to the grains. Twenty minutes at 15 psi (250F/121C) really produces nice melanoidins. There is hope - don't give up yet! Jeff - --- Jeff Renner in Ann Arbor, Michigan USA, jsrenner at umich.edu "One never knows, do one?"

Date: Thu, 8 Mar 2007 09:57:15 -0500 From: "Tom Viemont" <t_viemont at hotmail.com> Subject: Keller Bier Rick- Great post about maltiness and the necessity of decoctions in HBD 5157. Can't say I'm willing to step up to the decoction plate yet. My first lager is still in the fermenter. I am very interested in hearing more about that Keller Bier recipe, though. Can you share a little more with the class? Best regards, Tom Viemont Raleigh, NC Return to table of contents
Date: Thu, 8 Mar 2007 12:07:24 -0500 From: "Rick Garvin" <rgarvin at garvin.us> Subject: RE: Kellebier Tom, The Franconian Kellerbier that Christine and I make is a distinct historical style brewed by more than 100 breweries in the Northern Bavarian region of Franconia. It is not just any style of lager served with yeast like a Keller Pils, Keller Helles or Keller Bock. Dirty little secret: you are more likely to find Kellerbier in Bamberg than Rauchbier. I have more on this if you are interested. The color of Kellerbier runs from a relatively pale beer such as St. Georgen Brau or Lowenbrau from Buttenheim to the more frequently seen light-medium amber such as that Mahrs' Ungespundet-hefetrub. This is usually served Ungespundet (unbunged) by gravity with low-medium carbonation. Our version is towards the St. Georgen lighter end of the spectrum. The darker versions are sometimes called a Vollbier, which in Franconia is a red/amber Kellerbier. This is an overloaded term and confusing since vollbier is also a taxation classification. More info at http://www.franconiabeerguide.com/. Subjective impression: crisp hoppy beer with malt support, white pepper Spalter character in bitterness, flavor and aroma It's a pretty simple beer: OG: 1.050 FG: 1.010 IBU: 45 SRM: 4-7 estimated Water: enough sulfate to support the hop bitterness 82% Pils malt 18% Vienna malt 100% Spalter hops Single temperature infusion mash at 150F with 1.5 quarts water per pound Hop schedule 60 minutes - 40 IBU (about 2 oz per 5 gallons) 10 minutes - 5 IBU (about 1.25 oz per 5 gallons) Attenuative lager yeast, we use WLP830, fermented at 50F for two weeks and then cellared until sulfur dissipates. We have gotten pretty good results with fermentation temperatures between 45F and 65F, but 50F provides the best flavor integration with this yeast. Serve as keg beer or, for a fun party, serve from a firkin under gravity with light carbonation the way they do in Brauerei Ausschanks in Franconia. Cheers, Rick Return to table of contents
