Our estimates are close to what is stated on the can of Budweiser: depending on OG, we got ABVs of between 4.8 and 5.1%. That lower end does jibe with the lawsuit's claim that the beer is watered down by "three to eight percent" -- but as you can tell with the data spread, my numbers are not sturdy enough to be used in court for either side of the debate, and we didn't even both measuring the Bud Ice values. Happily for us (and, apparently, Anheuser-Busch), White Labs of San Diego also tested AB's beer, including Budweiser, Bud Light Lime and Michelob Ultra, right out of the packaging. White Labs, for those who aren't into brewing, is an independent company who sells yeast strains and a variety of analytical services to wine and beer makers. White Labs' method, which uses a precise near-infrared laser spectrometer to directly measure the amount of ethanol in a sample, is more precise than my kludgy hydrometer reading, and one doesn't need to know the starting gravity -- in fact they offer their testing services to microbreweries and home brewers so that everyone with $100 can test for what big breweries routinely do: chill haze, IBUs, ABV, turbidity, calorie content, etc. According to NPR (who commissioned the tests) and a White Labs analytical lab employee Kara Taylor, the Anheuser-Busch beers all had the proper amount of alcohol by volume. For example, cans of Budweiser say that the beer is 5% ABV; a can of it tested to be 4.99% ABV. Why the plaintiff's lawyers couldn't manage to pony up $100 of their own to get the offending beer tested before launching the lawsuit is beyond me and just about anyone else out there who knows a thing or two about brewing.
