Cold tapwater + sodastream. You can filter your tapwater if needed in your area.

Polar Seltzer

Liquid death

I like Waterloo for their flavors, but very little hits that super carbonation level that topo Chico does.

I have a soda stream I was gifted used from my aunt, and I like my tap water so I should give that a go.

Dick Cavett and Julia Child did a taste test 44 years ago.

I drink pamplemousse La Croix. I just really enjoy it, way more than any other flavor or brand.

If you’re only talking about plain I don’t have a recommendation, but for flavored I prefer Waterloo.

Mineragua is my go-to these days.

Jarritos Mineragua isn’t bad, and comes in glass bottles, but I still like Topo Chico in glass the most. I don’t drink it often though.

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.

My other personal recommendations are Borjomi or Maravella.

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.

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.

For all you sodastream people - I want you to know you are supporting genocide.
