Fee Bros makes a dozen or more kinds of bitters. I use their Old Fashioned, Orange, and Lemon kinds. A dash of Orange in gin is fabulous.
I bet a dash of their lime bitters would be a nice touch for a gin & tonic.
Hey Math, bit off track, but you started it !
There is also quite the variety of tonic waters available now too.
We've been enjoying the Fever Tree varieties for the last couple of months.
