"The only clear winner: cheap vices. Among the sectors with positive returns were cigarettes, cigars and tobacco, sugar and confectionery products, and fats and oils, which each gained between 1.6% and 7.5% annually."
So if fattening, carcinogenic vices were good bets in the Prohibition era, here's betting booze is the best bet now.
You don't have to tell me twice: But not sure Maker's Mark is publicly held.
