Peligroso Anejo is made from 100% Highlands agave and aged 12 to 18 months in ex-Tennessee whiskey barrels. It is bottled in an opaque, black bottle — I presumed to amp up the “dangerous” mystique of this slightly overproof (84 proof) tequila — but after pouring, the real reason becomes a bit more evident. In the glass, this is the lightest-color anejo I’ve ever seen. Comparing it next to Peligroso Reposado (which is light to begin with), it’s hard to tell a difference.
