The quinine in tonic water makes it bitter. Tracey

Hi
We use lemon juice for sour and indian tonic water for bitter

I think we just use coffee from the staffroom for the bitter.

Yeah....we use black coffee for the bitter and vinegar in water for the sour.

thank you all!
i've got indian tonic water & lemon water!

Check your tonic water, because I bought a home brand one last year, and it had sweetener added to it. Kinda defeated the purpose really. The branded stuff in a little four pack was better, and that way you usually only need to open one bottle per class anyway.

i bought the schweppes one...it does say there is sugar in there...! oh dear..

Waste not...Buy a bottle of gin to go with it not forgetting the slice of lemon. And then give 'em black coffee for the taste test and yourself after too many G & T's.
