Correct: I like G&T as much as anyone, but soda water beats tonic hands down for bringing out the flavour of your gin: you can put a dash of bitters in it too- that's also very good.I find diet tonic too sweet now for my gin so far last three months+ I have been drinking soda water with my gin and ice and slice. You really get the flavour of the gin and you don’t risk the probs with the tonics. Recommend to you gin and tonic lovers out there
