The coffee community is a place where our obsession feels shared. Where we can talk about tolerances, extraction, and what actually matters in a grinder, and the person across from you just gets it. Getting to meet so many of you in person made that clear all over again, and we are grateful for every conversation.
Thank you for being a part of this journey with us.
