Q is for Quinine

Here's some built-in cocktail trivia: QUININE is the ingredient that gives tonic water its astrigent flavor, and it's derived from a South American tree bark. Premium varieties are worth the small splurge: They're made with real quinine, which has a fresher taste than quinine flavoring.

Try tonic in the classic cocktail the Vodka Tonic.
