The Martini model, at its core, is a spirit (usually gin or vodka) plus an aromatized or fortified wine. Vermouth classically plays the latter role, but sherry also has along history of contributing its particular talents to the mix, as in the classic Tuxedo cocktail. “Manzanilla or fino sherries bring nuttiness and a bit of saltiness,” says Sam Ross. “That salinity works really well with the Gibson,” the classic Martini twin that’s garnished with a pickled onion. “A little brine in there touches up that flavor from the sherry—not so much that it’s a dirty Martini, but more like a dusty Martini."
