So I've tried basically all of the seltzer brands now. I like Spindrift the best, but it's a little bit too close to sparkling juice (because it has real juice in it). On the other the flavors in La Croix, Waterloo etc. taste too fake.
I think what I need is Spindrift with a little less juice. Probably will just spring for a Soda Stream at some point.
Also, our local brewery is now producing hard seltzers. The 3 can options they are starting with are lemon-line, ginger and lemongrass. Had a little taste of the lemon-limempop last night and it tasted like Sprite - at 5%, 100 cals, 1 gram of sugar. These are going to be dangerous for the beach.
