Drop knowledge on your dad by introducing him to pisco, a clear spirit made in Peru that's finally catching shine in the States. It's not tequila or rum or grappa or vodka—pisco is in it's own category. But you can use it in virtually any cocktail you like. The strong spirit is distilled from grapes, and has a spicy flavor. Portón is widely considered the finest maker of pisco in Peru-your pops will be impressed.
