  1. NO , you can’t grind coffee in a blender. For grinding coffee you need a specialised grinder known as a burr grinder. The reason is because you need a consistency in the particle size of the coffee for brewing. Different grind settings are needed for French press, drip, pour over and espresso.

  2. You asked “Is it ok to grind coffee in a blender?” I am not sure what “ok” means to you in this regard, but it is possible to grind coffee in a blender. Some small electric grinders use a similar approach, breaking up the beans with blades. There are a few potential problems. One is that a blender blades are typically made to pull liquids down through the blades, and do not work well with solids. (Some high-end blenders like Vitamix offer a separate blade and container for grinding grain into flour.) But since you should be grinding a small amount of coffee, that is not a big issue. Second is that blending heats the materials, but again for a small amount of coffee the heat should not be excessive. Third is that a blender will produce a mix of material sizes, rather than a very even grind, and this is a bigger issue. You can make coffee, but the “fines” will cause it to extract unevenly and potentially clog a filter, causing an excessively slow brew. For espresso it really won’t do at all. For other ways of making coffee, it works but is not optimum. Fresh ground coffee prepared in a blender or whirly grinder will generally be better than stored pre-ground coffee, but not as good as coffee prepared in a good burr grinder.
