Could you elaborate on this? What is a carbonation cap and how will the whole system work? I just hook up a CO2 can to the system and stick it into a container with my cocktail?
Basically I want to carbonate gin/vodka cocktails to make them better. What's my best option? I'm OK with a wrench/basic plumbing, but if I can spend a few bucks more for a better/more reliable system I'd do that since parts for a DIY solution won't be free either.
Also what are good refill...
