Every CO2 supplier we could find in the San Jose area (California) was checked one by one, and 15 of them made the list. 2 will refill the cylinder you walk in with. 11 only swap it for a different tank, which matters if yours is new or an odd size. 2 would not confirm either way, so those are marked call to confirm rather than guessed at. 2 confirm food grade CO2 for anything you actually drink; the common sizes here are 60L, 10lb, 5lb; most cover soda, homebrew, welding.
