This tonic was created through much research of classic recipes from a time when tonic was for more than just flavor. Original tonics were created using cinchona bark as it was the source of quinine. It"s purpose? To prevent malaria! The trouble was quinine is extremely bitter. With that in mind sugar was added for sweetness and citrus was added for tartness. In addition other herbs and spices made it into various recipes. Through research of those original recipes, we offer this for your drinking pleasure. Full of fresh bright citrus and slightly floral flavors with a lingering but pleasant bitterness. This is what your gin and tonic was meant to taste like! Contains: Cane sugar, cinchona bark (quinine), limes, lemons, grapefruits, oranges, lemongrass, ginger, grains of paradise, & a few other secret herbs & spices. Our Tonic is highly concentrated and very thick to give you the best value as well as the best flavor on the market. To make tonic water simply add 1/4 to 1/2 of an ounce of Tonic Syrup to 3 ounces carbonated or sparkling mineral water.
