---------------------------------------------------------------------- Date: Tue, 12 Jun 2007 07:16:25 -0400 From: beerdan at optonline.net Subject: British Pints vs American Pint vs Syracuse Pint I would like to add the Long Island Pint. The bars here use cheap shaker glasses, used to mix drinks, as a pint glass. Unfortunately, you have to point out to them that a shaker glass is about 14. 6 ounces and not a full 16 ounces. Just another reason to drink homebrew... Cheers, Dan Date: Sat, 09 Jun 2007 13:41:50 +1000 From: Wes Smith <wessmith at ozemail.com.au> Subject: British pint vs. American pint vs. Syracuse pint Peter Ensminger makes a good explanation of the old English "Imperial" system. Just one small point Peter - an Imperial pint is 20 Imperial ounces. 1 Imp gallon = 8 Imp pints = 160 Imp ounces = 4.546 ltrs 1 Imp ounce = 28.4125 ml Its been so long I had to go and look it up! Cheers, Wes "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"." Return to table of contents
Date: Tue, 12 Jun 2007 07:27:05 -0400 From: Fred L Johnson <FLJohnson52 at nc.rr.com> Subject: Re: Olive oil Steve provides a nice brief description of the nomenclature of the fats we've been discussing and reported the following in a study by Taylor et al. in which "lipids" (apparently predominantly triglyceries) were added to wort before fermentation. > This particular lipid extract included ~60% triacylglycerides and a > very > high 10% plant sterols. The beer resulting from the lipid enhanced > wort had LOWER final FA content as well as lower esters and fusels. It is without doubt that Taylor's adding oil to wort would initially result in the emulsification of the oil within the wort, probably by phospholipids from the grains and hops. This emulsion of triglycerides (triacylglycerols) would become a "sink" for the few nonesterified (free) fatty acids floating around in the wort and would effectively sequester most of these nonesterified fatty acids in the interior of the emulsified oil droplet. It is reasonable that the addition of oil actually decreased the availability of nonesterified fatty acids to the yeast, yielding the results reported by Taylor. Another point regarding Taylor's study (which I have not read) is that the fatty acids referred to within the yeast must certainly have been overwhelmingly esterifed to sterols or glycerol. The presence of truly free fatty acids in cells is fleeting, and may even be partly an artifact of the preparation, because free fatty acids are actually quite toxic to the cell. They are probably present only during the moment they are being transferred from one esterified molecule to form another. The presence of predominantly unsaturated fatty acids within the yeast probably merely indicates that the enzymes performing the esterifications favor the use unsaturated fatty acids over saturated fatty acids, not that they preferentially extracted unsaturated fatty acids from the oil. I'm not a microbiologist, so I don't know much about yeast lipid metabolism, but I studied mammalian lipid metabolism for many years in a previous life, and triglycerides are not something that cells can deal with directly to a large degree. They must hydrolyze the fatty acid from the glycerol and reesterify them to other molecules. I reiterate: if one wishes to provide fatty acids to yeast, one shouldn't do it with oil. One should use a dilute solution of the salts of the free fatty acids (soap). Fred L Johnson Apex, North Carolina, USA Return to table of contents
Date: Wed, 13 Jun 2007 00:15:31 -0400 From: "Peter A. Ensminger" <ensmingr at twcny.rr.com> Subject: beer measurement Another hbd'er asked me (privately) about the "barrel". A US barrel of beer is 31.00 US gallons (=117.3 liters); a "keg" is half of a barrel (=15.50 US gallons). My favorite local, www.bluetusk.com, has a firkin or two of cask conditioned real ale every Friday-Saturday. A firkin is 9 imperial gallons (=40.91 liters), or 1/4 of an imperial barrel. So! Would you rather have a barrel of beer (31 US Gallons) or a barrel of oil (42.00 US gallons)? Cheers! Peter A. Ensminger Syracuse, NY Apparent Rennerian: [394, 79.9] Return to table of contents
Date: Wed, 13 Jun 2007 14:16:10 +1000 From: <Mark.Hibberd at csiro.au> Subject: Re: British pint vs. American pint, Fluid Ozs Following up on the pint discussion, I've always wondered why the British Fluid Ounce (28.41 ml) is just slightly smaller than the US Fluid Ounce (29.57 ml)? Wes Smith (HBD 5194) noted that an "Imperial gallon" is the volume of water that weighs 10 lbs at 62 deg F. An Imperial Fluid Ounce is 1/160th of this. The volume of a US gallon is defined quite differently. It is 231 cubic inches, which was the definition adopted during the reign of Queen Anne in 1706 and retained by the USA. [See "Gallon" at wikipedia for the history of changes in the size of a gallon back to the 1200's.] A US Fluid Ounce is 1/128th of this. Just to show that even metric isn't standard, in Australia 1 metric tablespoon = 20 ml = 4 metric teaspoons (5 ml) Every where else, 1 metric tablespoon = 15 ml = 3 teaspoons Talking of units, I put together the following useful table of English, American, and Metric units some time ago. It may be of use to others. VOLUME MEASURES (IMPERIAL) 1 Imperial (British/Australian) gallon = 8 Imperial pints = 4.546 litres 1 Imperial pint = 20 Imperial fluid ounces = 568 ml 1 Imperial fluid ounce = 28.41 ml 1 Imperial barrel = 36 Imperial gallons = 163.7 litres 1 Imperial barrel = 2 kilderkins = 4 firkins VOLUME MEASURES (USA) 1 US gallon = 8 US pints = 3.785 litres 1 US pint = 16 US fluid ounces = 473 ml 1 US fluid ounce = 29.57 ml 1 US barrel (bbl) = 31 US gallons = 117.3 litres VOLUME MEASURES (METRIC) 1 hectolitre = 100 litres 1 droplet = about 0.1 ml WEIGHT MEASURES 1 kg = 2.20 pounds 1 pound = 16 ounces = 454 grams 1 ounce = 28.35 grams Mark Hibberd Melbourne, Australia Return to table of contents
Date: Wed, 13 Jun 2007 06:21:50 +0200 From: Thomas Rohner <t.rohner at bluewin.ch> Subject: more beer measures Hi Peter i live in Switzerland, close to Bavaria and Austria. A Mass (we don't use the sharp "S" that looks like a B that is open at the bottom) is one litre now, but that wasn't always so. When i was at the monastery in Andechs, i bought a book about cooking with beer. In this book, they also told stories of the old times. One goes like this: They had a abbot there, he drank 5 Mass daily. The place was used to get pretty crowded on holydays and summer sundays. On one occasion, the emperor or regent of bavaria came to Andechs, but all the seats where already occupied by "common" folks. He started to complain, but the abbot told him to put his bottom on the grass like everyone who hasn't got a seat. So the story goes, but then they added that a Mass at that time was more than 2 litres. It looks like this abbot was quite a alcoholic. 10 litres of beer makes roughly 20 pints. If you know the andechser Doppelbock, i wouldn't have survived this, even with their lightest brew. A Mass translated means a measure and measures have changed over times. Before the metric measurements were introduced in Bavaria, a Mass was something like 1069mL. If you ordered a "bottle" here in Switzerland 20 years ago, you would have gotten a 580mL bottle. In the meantime this volume sank to 560, 540 and now mostly 500mL. The breweries used this for "hidden" price hikes. The 500mL crown capped bottles have by far the largest volume in the market now. That's why we use them to bottle our beer as well. Here is a link to the german wiki of beer measurements and serving sizes. One cought my eye, it's from Saxony and it's called a "Biersemmel". Freely translated it means "a roll in a tin can" (roll like in small bread) http://de.wikipedia.org/wiki/Bierma%C3%9Fe Cheers Thomas Return to table of contents
