Q Tonic is by far my favorite tonic water. It avoids the usual high fructose corn syrup that fills up commercial tonic waters with a cloying sweetness and uses agave syrup instead. It's not too sweet, with a sharp, herbal edge of quinine. The taste is clean yet full and not too sweet - you haven't had a really great gin and tonic until you've tried one with this stuff. See the Brooklyn founders of this newish company here, and also check out their Q Ginger Ale.
