I am mostly pounding La Croix and Polar seltzer. Nice that someone imports them here. Really thought there'd be a local equivalent by now to bring the cost down but nooope.
I quite like some of the kombucha that is about but they are pricey.
Sainsbury's used to a cola one that was great, it was like a really spiced cola, can't find it now. I don't think the brand even make it.
