Micron Reference Card

Empirical

Welcome to your Empirical Micron Reference Card!

We want you to get the most out of each coffee. That’s why all of our coffees come with a specially curated recipe and a recommended micron grind size. Having this precise baseline takes the guesswork out of dialing in, meaning less wasted coffee and a better cup, faster.

We standardize our recipes by micron size to highlight the unique tasting notes of each roast. If you’re already using a grinder with built-in micron readings, you might not need this card. Otherwise, it’s the simplest way to match our recipe at home.

How to use

Match your grinder's setting against the printed micron scale to quickly cross-check grind size for pour-over, Aeropress, and espresso. Keep it by your grinder for fast recipe dial-ins.
