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.
