Pisco is a grape brandy from Peru and Chile, distilled from fermented grape must. Peruvian pisco is unaged and clear and tastes purely of the grape; Chilean pisco may be rested in oak.
Its best-known drink is the Pisco Sour; the Chilcano, with lime and ginger ale, is the usual highball. If the drink has egg white, dry-shake it first without ice to build the foam. Pasteurized white is the safer choice. For a floral drink, reach for an aromatic-grape pisco; for a rounder base, a Quebranta.
Another style of pisco
Swaps straight in, though a Peruvian bottle and an oak-rested Chilean one taste different.
Singani
Bolivia's brandy and the closest relative. Use the exact same amount.
Unaged grape brandy
Works one for one.
Darkens the cocktail and covers the grape character with oak.
A last resort. Distilled from pomace, it tastes sharper and more rustic.
Once opened, aromatic piscos such as Italia, Torontel and Moscatel slowly lose their perfume to the air in the bottle. Quebranta and the other non-aromatic grapes are far steadier. Either way, keep it dark and upright, and move what is left into a smaller bottle as it empties.
