Kruve Brewer Stainless Steel Measuring Tool

Designed specifically for coffee lovers, the BREWLER is a handy stainless steel measuring tool that lets you quickly reference the size of green beans and coffee grind. The BREWLER puts a measurable number next to fine, medium, and coarse. No more guessing or references to sea salt. The BREWLER also includes a metric ruler up to 16 cm and a quick conversion table for common brewing-related conversions.

How to use?

Take a small amount of grind and place it on a flat surface. Use the BREWLER to line up the size of the particles with the holes in the BREWLER. Since your grind likely has various particle sizes, line up both the smallest and largest particles and note their sizes. These two numbers will give you the grind range in microns.
