---------------------------------------------------------------------- Date: Thu, 08 Nov 2007 05:40:30 -0500 From: "A.J deLange" <ajdel at cox.net> Subject: CO2 Volumes When considering volumes of CO2 dissolved in beer most of us use the Zahm and Nagle chart which is taken from ASBC MOA Beer-13. Both the Z & N chart and the ASBC table are clearly marked as being for 760mm and 0C. This is very close to the IUPACs standard atmosphere (760.001mm Hg, 101.325 kPa, 14.696...psi) but note that all calculations specified in the MOA refer the measured volumes back to 14.7 psi. This is significant only because there are several "standard" atmospheres out there. A.J. Return to table of contents

Since then I now take the spigot apart and sanitize it. Then attach to the bucket and sanitize that. This solved my sour beer problems. Glyn Southern Middle TN Return to table of contents

Date: Thu, 08 Nov 2007 12:26:13 -0500 From: Bob Hall <rallenhall at henry-net.com> Subject: RE: sour bottled beer I typically either keg or bottle entire batches of beer, but occasionally fill a few bottles apart from the keg for contests or travel. I have a large jar of Prime Tabs that I have used for a number of years for this purpose. Over the summer I had several successive six-packs of bottled beer turn phenolic. Keg version was fine, bottle cleaning/sanitation the same. Am I correct to assume that priming tablets are the source of infection? I haven't been able to find anything on the web that linked priming tablets to infections. Along the same line, do any of you have tricks you use to prime a small number of bottles now that I'm a bit gun-shy about priming tablets? Cheers, Bob Hall Napoleon, OH Return to table of contents
Date: Thu, 8 Nov 2007 20:03:13 -0000 From: "Ant Hayes" <anthayes at btinternet.com> Subject: Biological sources of chlorophenols in beer I have run into a view that some chlorophenols in beer may be due to inadequate sanitation, i.e. due to infection. This contradicts what I was taught. I have not found anything on the internet or in any of my books to support the assertion (beyond ambiguous statements including phenols and chlorophenols in the same sentence - e.g. "Thus phenolic and medicinal off-flavors rising from volatile phenols and chlorophenols have been caused by some species"). It is well documented that yeast and bacteria can produce phenols, e.g. 4-Ethylphenol (4-EP) and 4-Ethylguaiacol (4-EG). However it seems unlikely to me that they could produce chlorophenols. Please let me know if you have any evidence one way or the other. Ant Hayes Hildenborough, Kent Return to table of contents
