You won't find a simpler drink in the world than pouring three bottles into a bowl for a large-batch Negroni Sbagliato—a combination of Campari, sweet vermouth, and prosecco (which takes the place of the traditional gin). Jeffrey Morgenthaler, bar manager of Clyde Common in Portland, is known for barrel-aging cocktails and other fancy bartender tricks. But when he throws a party, he makes this easy, lightly bitter drink. Here's how: Chill one bottle each of Campari, Cinzano sweet vermouth, and good, inexpensive prosecco. Dump all three in a serving bowl with a hefty block of ice and serve with big ice cubes.

If you decide to go the sour-mixed-drinks route, the conventional wisdom on citrus juice is that it goes bad within a few hours. "That's a myth," says Don Lee of Cocktail Kingdom in New York City. "I did a bunch of tests, and no one will notice if the juice was squeezed the night before." The booze will preserve the citrus in pre-batched cocktails.

Erick Castro of San Diego's Polite Provisions keeps pre-made cocktails in 750 ml bottles (you can use empty wine or liquor bottles) in his fridge for hosting on the fly. We especially like the Full Windsor, his riff on the Vieux Carré.

Castro also posts a menu with ingredients, so that no one needs to interrupt a conversation to find out what's in the drink.

Morgenthaler uses a cake pan and simple garnishes for showstopping ice. To make it, put edible flowers or citrus wheels in a Bundt pan or square Tupperware container, cover with ice, add water to the top, and freeze for two days. Once it's frozen, run the pan under hot water to release the mold.

A host who always has a glass in hand is a host who is having fun. But that calls for something lower proof. To that end, Toby Maloney of The Violet Hour in Chicago recommends Dolin Blanc on the rocks with a grapefruit peel. It's tasty, it's festive, and you can sip on it all night.
