Hi, I'm Jerry, host of the Sunday Brew Club in Luzern, where we brew, compare notes, and geek out over extraction until every cup gets better.

I wrote this manual because great coffee isn't magic, it's method. Repeatable, understandable, teachable. This is everything I've learned through years of brewing and hosting the club, distilled into one guide. No fluff, no gatekeeping.

I wrote it the way I brew: with precision, patience, and a genuine love for the process.
