Tonic goes great with gin and vodka, and Chad Eschman at VinePair shares his method for making some killer tonic syrup you can use on your own custom cocktails at home. You'll need one and a half cups of water, one and a half teaspoons of chopped Cinchona bark and one cup of cane sugar. (Cinchona is native to America, but Australians can order the bark online.) Bring the water to a boil in a small saucepan, then add your Cinchona bark and any other additional ingredients you may want (like citrus zest). Simmer for about a half hour, let it cool then use a French press to separate the liquid from the ingredients. Then add your cane sugar to your liquid in a sealed glass container and shake it up. When you're ready to make a cocktail, add about a 15mL of syrup to some sparkling water and you'll have some great-tasting homemade tonic water. You can find the complete recipe at the link below.
