It's the quintessential summer drink. The great Italian aperitivo. What James Bond mixes for himself in Thunderball. And like any proper gentleman's cocktail, the negroni is something of an acquired taste. The first sip, bracing and sharp, packs a punch. But as you drink (and the ice melts), it tends to mellow. Or maybe you do. Because you quickly begin to appreciate the subtle thirst-quenching contradictions of the citrusy bitterness, just sweet enough to be pleasantly refreshing. What's more, it's one the easiest cocktail you can make. You can even mix a big batch in a pitcher for a party. The proportions are the same. Simply combine one part Campari with one part gin—any'll do, but we prefer the earthy sweetness of Plymouth—with one part sweet vermouth. Then start sipping, because this is a drink that can't be guzzled. It forces you to slow down and enjoy yourself. Not a bad thing to keep in mind come summer.
