Say "cheers" to a modern classic: real quinine tonic syrup. Handcrafted in San Francisco, this micro-batch syrup goes right to the source for its authentic character, showcasing natural quinine from Peruvian cinchona bark. Fresh citrus, spices and a hint of lemongrass highlight the complex mineral flavors of quinine, while organic blue agave nectar adds just the right amount of sweetness. A classic companion for gin or vodka, the syrup also pairs beautifully with bourbon, whiskey, rum and tequila—or enjoy it in your favorite nonalcoholic refreshers. To customize fizz, add your preferred amount of seltzer or sparkling water.
