"We age drinks that have a wine component, such as vermouth or Sherry, because the wine will oxidize a little bit. That brings out a lot of nutty, grassy, earthy flavors." —Jeffrey Morgenthaler; Clyde Common, Portland, OR
Combine 2 ounces bourbon, 1 ounce Campari, and 1 ounce sweet vermouth (preferably Antica Formula) in a large mixing glass filled with ice. Stir until glass is very cold, about 1 minute. Strain into a chilled cocktail glass or coupe or a rocks glass filled with fresh ice. Garnish with a lemon twist.
