Brioni

• 1 part Campari
• 1 part Sweet Vermouth
• 1 part Dry Vermouth
• 1 slice Orange
• 5 parts Club soda

Pour liquor over ice cubes in a Collins glass. Fill with club soda, stir to mix, and add orange slice for garnish.

My variation on the "Negroni". It's less alcoholic switching dry vermouth for gin, and with club soda it makes for a very refreshing summer drink!
