I like the ritual of it, for sure, but I'm not sure that's what makes it a good shot?

Regular coffee drinkers vs snobs are two vastly different categories. In the guy that ruins your fun. ;)

I grow my own beans and harvest rain water from my roof to use in my coffee ritual and ... am happy to let others do their own thing

I actually capture free hydrogen and oxygen and make my own water.

I literally have a friend that roasts their own and has a rainwater collection system.
