I haven't had that much ginger ale to be honest.
Just for you I will track down one of these in the local Sainsburys and report back
Yep, lots of different takes on ginger ale. The Fever Tree brand is an example of a premium small niche sorta item. You can bet this version will have some unusual flavor notes in the mix.
Couple years ago a thread mentioned the FT tonic water. I had tried it but it had too much going on and also was missing some much needed sweetness. Crazy money for a small bottle.
