When the sun is shining at the beach, whatever you’re sipping needs to beat the heat. Satisfyingly tart and just a little sweet, sours are a slam-dunk.

They’re a category of cocktails that come at you with a good measure of refreshing citrus balanced by sugar, honey or agave-based syrup and your spirit of choice.

In fact, that’s the crux of their one-two-three simple structure — and what makes them so versatile.

It’s merely a matter of some fresh-squeezed lemon, lime or grapefruit; a bit of sweetener (play around with liqueurs like elderflower, cassis or pamplemousse for an extra bit of dimension); and a liquor you love.

Whiskey’s your jam? Go classic whiskey sour, or one of that cocktail’s multiple riffs. Is vodka your go-to? Hello, cosmo! Love tequila? The margarita is the most popular sour on the planet.

And never fear, brandy lovers — you won’t be left out. You can happily sip on a sidecar. Dial into your desired flavor profile and shake up this season’s quenching cocktail crush with one of these lip-smacking recipes from popular Hamptons haunts — as well as an East End-inspired sip I created myself.
