Barsmith’s Dirty Martini mix contains freshly pressed olives for the perfect balance of flavor and smoothness to a classic cocktail with no added chemicals or colors, 12.7-oz. Bottle. We worked with California’s largest olive producer to bottle our olive brine unfiltered, giving a pure and rich saltiness that martini drinkers crave. The California Sevillano Olive is our signature ingredient, and puts Barsmith’s Dirty Martini mix ahead of the pack.
