This sounds awful. I’m an espresso snob and caffeine isn’t even on my list of why I love it. It’s like they complete ignored what makes a good shot and focused on one element.

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.

If you're not creating your own galaxy which can make free hydrogen, oxygen, and an environment to promote the evolution of a coffee plant over millions of years, you're consuming such an inferior product that you might as well drink instant coffee.

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

I'm also an espresso snob and got the complete opposite take. The idea of decoupling grind size and brew time from yield is super interesting. The only other device I'm aware of that does this is a pressurized portafilter basket but that's only there for people that don't have good enough grinders.

I'm curious why you focused on caffeine when the article says their study found that people tasted no difference

I'm sure someone like Giovanni Gaggia will improve it a bit, to the point there is nothing to improve anymore.
