I used to hate sparking water. Why would you want a fizzy drink that tastes like the worst parts of a lemon? That was, my friend, until fate gave me a coupon for a free case of Deer Park sparkling water and in my process of drinking through it, it finally clicked. "So this is what sparkling water is?"; this was a life changing moment.
Jumping forward a few years, I've dabbled with all sorts of brands including the notorious La Croix. My first sip of the lime flavor was magical, I was hooked. This tasted like dish soap to you Bill?
And when you get to the flavor combinations (≧▽≦), oh man. Pina Fraise is fucking gorgeous. So what's everyone's general consensus on La Croix? The only flavor I dislike is coconut because it's a little strong. And some taste better room-temp rather than cold.
Spindrift is great because they actually use a bit of fruit juice/puree. You get a nice carbonated drink with a hint of lemon/like/raspberry/grapefruit/etc. They even have unsweetened tea sparkling water now.
It's not sugar free, though. Each can has maybe 3-4 grams of sugar (which is still a heck of a lot better than 30-40 grams from an actual soda).
