Molex Field Notes
One good cup.
One useful system.
One meaningful connection.
A practical letter about coffee, operations, people, and the work behind the work.
Molex carries only a handful of coffees at a time, and writes about them the same way — a few things, in enough detail to be useful. Everything published here is either something we do in the roastery or something we have actually run in a business.
Brew Better
Ratios, grind, water, extraction. The handful of variables that actually change the cup, and how to move one at a time.
Origin
First-hand reports from the farms and the people who grow the coffee we roast.
