Water conservation is among the biggest environmental challenges in Southern California, and San Diego bartender Sean O'Connell created this bourbon cocktail with that in mind. The recipe requires no dilution and is meant to be served neat, which eliminates the need for ice. O'Connell batches the recipe in a pitcher and then chills the cocktail in the refrigerator prior to serving. At home, simply up the ratios accordingly, depending on how many servings you'd like to make.
