As was the case with original Indian tonic water, East Imperial is now the only tonic water sourcing all the key ingredients from Asia. This is the champagne of tonic waters. This is not a soft drink. Our Old World Tonic is a completely natural low-calorie tonic, with half the natural sugar content of other tonics. This is an authentic representation of what tonic water used to be at the turn of the last century before overly sweet tonics became the norm. Unlike other ‘diet’ tonics, we only use all-natural ingredients with no artificial colours or preservatives, and it is gluten-free. With only 20 Calories per 100ml (7.5gm of natural cane sugar) our Old World Tonic is the perfect way to enjoy your G&T without the guilt of calories. Upgrade your tonic to the authentic choice, and discover a new perspective on the wonderful world of premium gin.
