---------------------------------------------------------------------- Date: Fri, 08 Jun 2007 01:29:46 -0400 From: "Peter A. Ensminger" <ensmingr at twcny.rr.com> Subject: British pint vs. American pint vs. Syracuse pint Some discussion in another listserv inspired me to look up the value of an "Imperial pint", a unit of measure in Great Britain. In Britain, a pint of beer (or cider or perry) is an "imperial pint", which is 568.26125 mL (=19.2 fluid ounces). Apparently, the British government declared that an "imperial gallon" of water weighs 10 lbs at 62 deg F and the "imperial pint" is 1/8 of an "imperial gallon". However! You will often see that cans of beer in Britain contain 500 mL. This is known as the "metric pint". See: http://www.opsi.gov.uk/si/si1995/Uksi_19951804_en_2.htm Then again, my favorite local serves "22 oz pints". See: http://www.bluetusk.com/ . I declare this to be the "Syracuse pint". Cheers!

Date: Fri, 8 Jun 2007 08:56:19 -0700 (PDT) From: Matt <baumssl27 at yahoo.com> Subject: re: Olive Oil Jeremy and Steve disagree with New Belgium's math (or perhaps there is a typo in their message). Isn't there some simple math that can be done to at least get in the ballpark? I'll take a stab and someone can correct me if I'm wrong. *Ignoring sterols for a moment*, assume one fatty acid molecule roughly substitutes for one oxygen atom with regard to yeast fatty acid needs. 8 ppm oxygen is in that way replaced by 128 ppm oleic acid (8 ppm times 282 g/mol over 16 g/mol). For a 5 gallon batch, this is ~2.5 grams or ~3 ml (was baffled for a second when I originally got 2800 ml due to incorrect density in Wikipedia). So, New Belgium's numbers don't make sense to me either (though of course my initial assumption could be wrong). Fred, maybe Charlie Scandrett's reference answers your concerns about how the yeast split the triglycerides? Steve says: "I'll have to make a brief reply to Matt Baum's [sic] belated discovery that need unsaturated fats made with oxygen." That's not the "discovery" I was reporting, as I thought I made it clear that the science is nothing new. The discovery (not mine and not very belated) is that New Belgium has actually been using olive oil on a pretty big scale, with a level of "success" that encouraged them to make a million bottle of beer this way. (Notwithstanding the question of whether this same success could be achieved by eliminating the aeration AND the olive oil.) "> Question 1: Okay so what about that ergosterol? Does the linoleic, > oleic, or anything else in olive oil allow yeast to produce sterols? No !" Thanks for an unequivocal answer to my main question. I don't like taking things on authority, but the exclamation point seems to indicate you could back this up voluminously if I asked (which I will not). So, presumably New Belgium's pitching yeast is sufficiently stocked up on sterols (or their ferments would stick, because they are not aerating and the olive oil doesn't help with that). Seems like then that it is well stocked up with fatty acids as well (because whatever procedure is used to build up sterols would likely also build up fatty acids, and also because 300 ml of olive oil seems like too little anyway.) Of course, pitching yeast can be built up and stocked up to the point that no oxygen, fatty acids, or ergosterol need be added for a healthy ferment (and I do it all the time). It is starting to sound like New Belgium's pitching yeast is in a similar state. I wonder if they've tried skipping the olive oil. Matt Baumgart Return to table of contents

I'd have to pull them. My biochem is a little rusty since I changed careers. Take anything you hear from a brewer with a grain of salt. Or try the experiment yourself. Add some Olive oil to your wort, maybe extra virgin for the flavor. Jim Return to table of contents

It was great and I wanted to thank him. Alas, the email address he left is no longer active. So, if you are out there reading this Byron (or anyone who know him) it was great! john (near Mobile, AL) Return to table of contents
