A popular trend in American brewing is packaging beer in 19.2 ounce cans, known as stovepipes. Naturally, the first time that I saw that size, I was somewhat perplexed. And no intuitive explanation for the 19.2 figure presented itself to me.
Of course, the internet had the answer for me: 19.2 American fluid ounces is (approximately) equal to one imperial pint. Because an imperial pint is about one-fifth larger than an American pint, stovepipe cans are popular at sporting events, concerts, and the like, where patrons are keen to minimize time in the beer line.
When I learned that stovepipe cans are actually imperial pints, I had two distinct revelations. First, a scene from George Orwell’s 1984 suddenly made sense to me. Second, Australian drinking habits began to seem (slightly) reasonable.
First, in 1984, there is a scene at a bar in which an old man is perturbed that beer only comes in liter or half-liter glasses. He repeatedly orders a pint, only to be told that the barman–raised after the adoption of the metric system–has never heard of pints, quarts, or gallons. The old man complains that “a ‘alf litre ain’t enough. It don’t satisfy. And a ‘ole litre’s too much. It starts my bladder running. Let alone the price.” This struck me as odd when I read it long ago. To me, half of a liter has always been more than a pint, not less. In America, a liter is just a bit over two pints. But a liter is somewhat less than two imperial pints; each imperial pint is 0.57 liters or thereabouts. So the old man seems to have a legitimate complaint about his beers being more than two imperial ounces smaller than they used to be.
Second, when I was staying in Australia, I found that bar patrons generally did not buy draft beer by the pint. Rather, they drank rounds of smaller beers. The explanation offered to me was that a pint is a just a bit too large a unit. Being familiar only with American pints, I found this odd. Now that I know the Australian pint is about 19.2 American fluid ounces, the explanation for the smaller beers seems more plausible. (Of course, the people I drank with never had just one round, so ordering smaller beers generally smacked of inefficiency.)
My bemusement on this point was multiplied by the puzzling names for the variously sized smaller beer glasses; Australian glass sizes make Orwell’s Newspeak seem comparably reasonable. All of the sizes are officially in milliliters, but are clearly intended to approximate imperial ounce units (for example, beers of about 7, 10, or 15 fluid ounces are common.) But nobody calls the glasses by their actual (metric) or approximate (imperial) volumes. Rather, Australians employ names such as schooner, pot, or middy. And these names also vary from place to place, making it extra hard to know how much beer one may receive at any given bar across the land. For example, a South Australian in Brisbane may be pleasantly surprised when he orders a schooner, and gets 1.5 times as much beer as he expected. And virtually any traveller to Adelaide would be distressed to order a pint and receive only 15 imperial fluid ounces–five fluid ounces less than an imperial pint and some 1.5 American fluid ounces less than an American pint. Anybody planning on visiting Australian public houses should consult Wikipedia’s helpful chart on the subject.
Finally, although not in the nature of a realization, I wonder why the brewers stopped at 19.2 ounces and didn’t push right up to twenty. The 19.2 figure seems somewhat affected when compared to 20. Twenty is such a fine, round number. And 20 ounce beers are already popular at bars and taprooms across the United States, many of which offer 20 ounce pours.
A 19.2 ounce can of beer in America is appreciably more than a half liter and significantly short of a liter. It is also the same as a pint in Australia (with the exception of Adelaide.) It is equal to two pots of beer (in Brisbane or Melbourne) and is larger than a schooner by one-third. And finally, it is (to nobody’s great surprise) 3.2 ounces more than an American pint, and .8 ounces shy of a 20 ounce draft.
Beer of the week: Dragons Milk – This popular bourbon-barrel-aged stout comes from New Holland Brewing Company in a bomber bottle, a popular size for craft beer bottles. At 22 fl. oz., bombers are a fair bit more voluminous than stovepipe cans. But it’s not just size that counts. Dragon’s Milk is 11% alcohol by volume, and the alcohol is clearly noticeable in the taste and aroma. There are also notes of coffee and caramel. Dragon’s Milk is extremely smooth. The whole experience is like a not-too-sweet malted milkshake. It is so rich and boozy that I wouldn’t recommend having much more than one 22 oz. bomber (or a couple American pints or a brace of schooners or a half liter or a few pots…) in one sitting.
Reading of the week: An Essay towards a Real Character and a Philosophical Language by John Wilkins – The principle purpose of this essay is to propose a universal second language. However, this excerpt discusses the related notion of a universal and rational system of measurement. Although he suggests specific existing units, Wilkins greatly modifies the units so that they are all tenths of the next largest units. He also suggests, but does not press, the notion that we should abandon decimals for octals, because an octal number system is particularly well suited to the mathematical process of bipartition.
