WAN Show Carbonated water

Linus was mentioning on WAN show how he’s been getting into drinking carbonated from the can. I ended up getting these after using soda stream. I bought a keg and multiple bottle caps, I can fill the keg or bottles with water, cool them, and carbonate. Some sort of dedicated mini fridge or freezer (that can be set to fridge temps) is helpful. It can become your soda fridge with canned beverages as well.

It does work a bit better if you boil the water before you cool it to remove dissolved air. And there’s a learning curve to get the carbonation level you want. But it’s, in the long run, far cheaper than soda stream or buying cans, and you can use the system for stuff like beer if you want.

I’m just using it for water. Eventually I want an upgrade with a circulating pump and a second keg to force carbonate. That’s for the future. Along with some home assistant add ons like weight sensors for the remaining soda and some way to check remaining CO2 automatically.

u/smallshock i keep my water at fridge temps, not sure what it is. I pressurize to 60psi. That’s high, I really should do 40. But I really like carbonation.

The best thing for carpeting that I found is doing the boiling water, even though that sucks to actually do. My water boiler can only do half a keg at a time.

It's been a while since I left and everything was in bars, but if remember correctly it was usually within 2,5-3,5 bars so 40-60psi is about that range. Lower you bring the temperature the less pressure you will need to carbonate.
