I prefer "particle swarm optimization" a la here.

Actually, most American beers (ignoring market share and ubiquity ie., Bud = 1, Bud Light = 1, New Belgium Fat Tire = 1, Bridgeport IPA = 1, etc.) are far from water these days. In fact the vast majority (again, nullifying market share) are hopped enough to make most swill drinkers' faces turn inward and flee crying to their mommies.
