"Two simple principles lie at the bottom of the whole matter, and they may be precipitated into two rules. The first is that, when there is a choice, the milder drink is always the better-not merely the safer but the better. The second is that no really enlightened drinker ever takes a drink at a time when he has any work to do. There is, of course, more to it than this; but these are sufficient for the beginner, and even the virtuoso never outgrows them."
