Midnight Mixers Amber Tonic is handcrafted in Melbourne from the highest quality raw cinchona bark we can source. Our natural process for extracting quinine directly from cinchona leads to a full-bodied tonic with exotic spice and appealing bitterness. It makes a complete drink on its own, combines perfectly with gin, and is an agile mixer for a broad range of white and dark spirits, particularly Rum and Agave.
