Sadly, you can’t replicate San Pellegrino using tap water and a co2 tank.

You can come close, using distilled water and some powdered minerals that are available at homebrewing supply stores:

finally dehydrated luxury water

See my comment upthread… zip hydrotap. It’s closer to that German brand that starts with a ‘g’ but every bit as “real” as San pelligrino

You mean Gerolsteiner? Also, what Hydrotap machine are you referring to specifically? Zip HydroTap G5 CS? Just having this discussion with my wife and am researching options. Thanks!

I am in the US ... we have a "HydroTap Arc BCS":

A lot of people are complaining about SodaStream et al due to mineral content but my complaint is actually different! I prefer purified water anyway (I don't need the minerals for taste, tap water is good enough). I have a soda maker at home (it's not gas-based SodaStream-like, it creates CO2 through baking soda and citric acid). However, these do not carbonate water as much as Polar or Canada Dry seltzer waters. I like it when my water is maximally carbonated, it almost burns my tongue. Half-carbonated water tastes gross, it's like someone opened a can of seltzer and let it sit for 30 mins...
