A Vitamix blender can produce a ground coffee suitable for brewing and extracting. The exact shape of the ground coffee is not as precise as you would get from a high-end burr grinder. The Vitamix grinds coffee with the same variable-sized grind achieved with standard low-end coffee grinders. It is possible to produce grinds using the Vitamix for all the standard brewing methods, from French press to automatic drip coffee maker. Use the dry-blade container to grind coffee as it's designed for this purpose. Although you can use the wet-blade container, results won't be as good.
Measure out 2 cups of roasted coffee beans.
Set the left switch on the Vitamix blender to "Variable," the middle dial to the number "3." Check your owners manual because the settings may vary among models.
Add the beans and secure the top of the dry-blade container.
Turn on the blender and process for 15 seconds to reach a level of grind suitable for a standard drip coffee or French press. Further processing at the same speed for longer will produce a finer grade coffee suitable for espresso or Turkish coffee.
It is good to stop grinding every 5 seconds to check the texture of the grind.
