Buy Coffee Bean Grinder Buying a new coffee bean grinder can be a tough task if you don’t know where to start and don’t know the different kinds of coffee bean grinders. So in these video I discuss those kinds. One kind is a blade grinder, which is the cheapest kind, and the other kind is a burr grinder, which produces more consistent coffee but is more expensive. Conical burr grinders are the best, especially if you use oily or flavored gourmet coffees. If you just want to drink a cup of caffeinated something, then a blade grinder should be fine.
