He suggests seeking out Q tonic made with natural ingredients like agave nectar without as much quinine.
Gin and tonics came from the medicinal discovery that quinine could prevent British soldiers from contracting malaria in colonial India.
For the more ambitious home bartender, making tonic syrup isn't hard. The procuring of the ingredients takes a little planning ahead. You'll have to track down some cinchona bark (available online) and citric acid and boil it into a simple syrup. Jones suggests the simpler option of purchasing Bitterman's tonic syrup, a product he's kind of having a moment with, available at South Lyndale Liquor Store. It's perfectly balanced between the herbal notes in the tonic with a subtle sweetness that enhances the juniper in the gin. You can add your own soda water to control the fizz factor.
Once you've mastered the basics, there's no end to the way you can vary this drink. For an especially summery twist, mix it up with strawberries, mint, and rhubarb bitters. Gently press mint at the bottom of a shaker. Says Jones, "That's a pro tip. Don't tear the leaves or you'll get that vegetable flavor and a bunch of mint stuck in your teeth. Just press the leaves to release the oils. Add some sliced strawberries, gently crush them." Mix with gin, tonic, soda, and ice, top with four or five drops of seasonal bitters, and serve with a straw. "It's one of the only drinks where it's okay to use a straw because you want to get at all that fruit at the bottom."
