---------------------------------------------------------------------- Date: Mon, 23 Apr 2007 21:44:19 -0700 From: Norman W Jufer <jufernw at juno.com> Subject: Isopropyl Alcohol Bill Tobler asks why 91% isopropyl alcohol is not considered a good sanitizer. Pierre Rajotte in his excellent "First Steps in Yeast Culture" outlines the use of isopropyl alcohol as a sanitizer. In it he says "Alcohol is an excellent germicide. Most microbiologists agree that it acts by denaturing proteins. This action is more pronounced in the presence of water. It has its maximum effect when mixed with water at a concentration of 70% by weight. In some areas it is possible to purchase alcohol at a concentration of 90%. However alcohol at this concentration has a lower germicidal effect than at a 70% concentration." And as far as instant sanitizer, alcohol is actually slower than star san which is effective with a 20 second contact time. Return to table of contents
Date: Tue, 24 Apr 2007 06:52:51 -0500 From: "Jeff Dieterle" <djdieterle at localnet.com> Subject: 1/2 barrels to cornies Wondering if I would have problems filling 3 cornies from a keg. My kegerator is a chest-freezer-3-tap-tower and I like to use one of the taps to appease the bmc crowd. I checked on 1/6 barrels, but they aren't available in the mass consumption beers, the only Bud available was Mich Ultra. I'd go at by cooling the keg in the lower 30's to minimize foaming and use gas to push, probably also wicky something up on the corny relief valve so I know the corny has no headspace then push enough beer out of the corny with gas so the gas in side is not submerged.

Date: Tue, 24 Apr 2007 13:35:11 +0200 From: Thomas Rohner <t.rohner at bluewin.ch> Subject: Alcohol concentration Hi Bill when i remember correctly, it's because it can better penetrate the cells of our enemies at around 70% concentration. This is because of osmotic pressure at the cell wall. I always dilute it to 70%. Cheers Thomas Return to table of contents

Date: Wed, 25 Apr 2007 10:24:17 -0400 From: leavitdg at plattsburgh.edu Subject: Sinamar I have used Caraffa quite a bit, to introduce color into various brews, while at the same time limiting the amount of harsh flavor/s that can come from the darker / roasted grains. I recently read about Sinamar, from Crosby. Have others used this stuff for color? And, how much flavor gets departed? Darrell Return to table of contents

Date: Thu, 26 Apr 2007 18:42:50 -0500 From: "Mike Maag" <mikemaag at comcast.net> Subject: Isopropyl Alcohol Bill Tobler wonders about isopropyl alcohol. Yep, the 70% sanitizes better because it permeates the cell wall more easily/quickly than stronger concentrations, but is still effective. Hope this helps Mike Maag Shenandoah Valley Staunton VA Return to table of contents
