Kruve BREWLER 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 finally 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 16cm 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 size of the holes on the BREWLER. Since your grind most likely has various sized particles, you should line up both the smallest and largest particles and make note of their sizes. These two numbers will give you the grind range you are using in microns.
