A blender jar defines a geometry to impart vertical movement to material being processed in the blender jar, and, alternatively or in combination, improves the horizontal movement to the blended material. By configuring one or more agitators on the floor of a jar, laminar flow or symmetric flow of material around the jar is disrupted. The material is forced in an upward direction in the jar and, therefore, into more frequent contact with the cutter blades rotating in the jar.
