I've been playing around with beers between 9-13% alcohol. Stupidly, I just finished a "wheat wine" of 12 oz. and 11.5% ABV in less than 10 minutes, when I normally only drink any beer in an hour. This without having eaten anything today. It was Leviathan Triticus, of Harpoon's Leviathan series - the weakest beer in the series is 8.9%, with a series average of 9.785%. I go for beer efficiency ahead of volume - and if it happens to be delicious, then all the better. Just have to drink more slowly. ABV comparison - 11.5% per 12 oz (beer bottle) equivalent to 23% per 6 (wine glass), and of course equivalent to 92% per 1.5 (shot).
