In a panel discussion on beverage trends, Adam Hodak beverage director at Bonanno Concepts in Denver, explained a fairly new technique called “switching,” by which bartenders super-chill spirits so that the water freezes but the alcohol doesn’t. Then they remove the water and replace it with an equal volume of tea, juice or other liquid, allowing for a revved up flavor that doesn’t dilute the spirit, and eliminating a step in drink making at service.
