Same here. Tap + sodastream and Mio if I want a bit of flavor. Farm Boy (Canadian Whole Foods style grocer) has the best canned water tho. The flavors are so light and delicious. Orange & Vanilla or Pineapple take the top spots for me.
According to Consumer Reports, Topo Chico consistently tested the highest for PFAS among carbonated waters. But they also said almost all store-bought carbonated waters tested positive for PFAS.
I remember reading somewhere posted a while back on a social media aggregated site where a bunch of professional food taste testers unanimously agreed Polar was the best.
I have an old SodaStream that I picked up second hand for 20 bucks, and an adapter from amazon that lets me hook up to a bar/resto sized CO2 container.
Add in a 5 foot extension line from a bar setup so that it can live up on a shelf and we are done.
The savings are remarkable. Instead of 20 bucks for 60litres of water, which I go through in about ten days, I get about 5 months of super bubbly water for 45 bucks total.
This is a crazy recommendation but I think Canada dry plain seltzer is basically as good as topo Chico. I got some at a gas station the other day cause I was dying of thirst and it was as good as topo Chico my wife thought so too.
Waterloo Grape is the closest to an actual sugar-soda taste I've had. Does a great job at fooling your mind and tastes like grape. I also like the Ginger-lime combos from them and Nixie. Ginger does a lot to add flavor.
I've tried a bunch but found almost all the bottled fizz I can buy to be quite bitter. I own one of those carbon sifon things now. Probably better known as sodastream in the Americas
Personally my favourite is Nabeghlavi. I'm assuming that you're in North America based on your current choice, in which case I checked and you're in luck they do actually distribute to the US and Canada so you might want to look out for it but I imagine that as it's imported it would be a bit pricey.
Personally a San Pellegrino person but significant others hate small bubbles, Saratoga Springs seems to be the best compromise in the small vs big bubble debate.
