Guide To Coffee Bean Grinding: From Coarse To Fine
Cold Brew. When it comes to making cold brew coffee, the grind size is really important. For the best results, you'll want to use an extra coarse grind. This allows for a longer steeping time, which extracts more flavor from the beans. If the grind size is too fine, your cold brew can end up tasting acidic or sour.
