Liber & Co. has been handcrafting exquisite cocktail syrups over the past decade, and today their products are the secret sauce behind the cocktails at many of the world's best bars. According to the Liber flavor experts, "This is a refreshing, boldly flavored tonic made with superior ingredients including natural quinine, zesty citrus and pure cane sugar. We crafted the flavor profile to perfectly complement premium dry gins. As an uncarbonated concentrate, simply top this syrup with club soda for a superior tonic water. Next, go beyond the G & T by using the tonic syrup in novel cocktails."
