Greetings, Beerlings! Take me to your lager... Large leaps in my SPAM protection strategy tonight. Unfortunately, not so on my virus protection strategy(CLAMAV and milter are not getting along at the moment...) If your digest has gone missing, there are two potentials: you or your domain appear on one of the added blacklists or you had the misfortune of being one of the "victims" of the virus filter failures during experimentation this evening. In any case,you should find the Digest intact on the website or in the archives - and my apologies for the inconvenience! - -- See ya!

Date: Wed, 08 Sep 2004 23:24:57 -0700 From: Don <don at steinfillers.com> Subject: Volunteers needed; LA Fair Beer tavern Are you in the S. California area? If not skip to the next message. But if you are and you like to talk beer and want to help spread the word about quality beer as well spending a day at the LA Fair on us, then sign-up to volunteer at the LA Fair's Tavern run by California Fermentation Society. There are still a few remaining time slots open, so don't delay, sign-up. The beers being served are those entered in the Fair's official commercial beer competition and as a volunteer, you may have a few on us (just don't over indulge). Both award winning beers and Sign up can be found at: http://calferm.org/faircomp/index.html Note: this sign-up page does not update in real-time. It is done manually on a daily basis and even though you sign up for a given time slot there is no guarantee that it is still open.

Date: Wed, 8 Sep 2004 23:43:55 -0700 From: Bob Tower <tower at cybermesa.com> Subject: Polyclar Useage I've started using Polyclar in an attempt to clear up some chill haze. Does anyone have any tips on adding it to the beer? My main concern is contamination. The form that I get it in are small zip lock bags enough to treat 10 gallons. I'm concerned that it's not likely sterile and don't feel comfortable just dumping it in and stirring. What I've tried is wetting it with some vodka (which turns it into a gooey paste) in an attempt to sterilize it. Since Polyclar is plastic dust I figured that boiling it was out of the question! Just did that tonight so I won't know the results, but I'm not too worried that what I did will hurt it. I'm just wondering if there's a better way or if people out there have been adding it directly to the beer without any problems with contamination.

Date: Wed, 8 Sep 2004 23:57:49 -0700 From: Bob Tower <tower at cybermesa.com> Subject: Re: That British Caramel Taste Fred Johnson is looking for a way to increase the caramel taste in his British-style ales. I've noticed that an increase in caramel flavor and complexity can be achieved by using a blend of crystal malts rather than a single type. For example, rather than using just Crystal 60 in a recipe, substitute three or four different colors in decreasing amounts with increasing color (1 lb. of 15, 0.75 lb. of 35, 0.5 lb. of 60, 0.25 of 75, 0.125 lb. of 120) to achieve the same color contribution as the single amount of crystal in the original recipe. You'll have to play around with the proportions to keep the color of the finished beer the same but if you're using Pro Mash it's a snap. Another thing you can try is to remove a small portion of the wort from the kettle and boil it down to a syrup (be careful to not scorch it) and then add this back to the kettle. This will definitely take some trial and error as far as proportions but I've found it to be effective. Start with a small amount (maybe a quart or less in a five gallon batch) first and increase the amount you remove if you want more impact. Bob Tower Los Angeles, CA Return to table of contents

A couple of people suggested this. When I am relying on my refractometer, I generally don't have enough liquid for a hydro sample. I took some readings last night and compared them with my hydrometer and the refractometer is comparable -- THIS time. In the past it has not been. > From: Christopher Farley <chris at northernbrewer.com> > Subject: Re: ATC Refractometer from Northern Brewer > If you have a good scale, you can put 10 grams of sugar in a large > cup.

I think there is something systematically wrong with either my calibration method, my sampling, or reading. I was hoping there might be something unique about this unit that someone else figured out that would help me determine the problem. > By the way, I find that refractometers (unlike, say, pH meters) are > very low-maintenance instruments.

Very simple. Thanks to the other on and offline responders as well. Brian, this may be what you were trying to explain to me. Tony, I wonder if this might work for that Thwaites keg? An American nickel is about 2cm wide. In Digest #4597: I also asked about "Keg #2 is a Bass\Tennents keg and it has a completely different valve. It is triangular with rounded corners rather than circular." I have since figured out that this is a type "G" Grundy keg but I still don't know how to open it. Actually, I traded it away yesterday to someone cutting for a kettle. I'd still like to know just for knowings sake. Slainte, Tom Davidson Bawlmer, MD Return to table of contents
Date: Thu, 9 Sep 2004 20:33:41 -0400 (EDT) From: "Alan McKay" <amckay at neap.net> Subject: corn vs grape sugar correction I was corrected in private email by Greg Lehey : "Traubenzucker" is a semi-official name for laevulose (often called fructose). I thought "corn sugar" was a mix of laevulose and dextrose, and I've seen reports on this list that it's dextrose. - -- http://www.bodensatz.com/ The Beer Site Return to table of contents
