Coffee mills are also called coffee grinders, although there is a difference in the way each grinds the coffee. Large floor-standing or counter-model coffee mills were used in the nineteenth-century country store. Small home mills were first made about 1894. They lost favor by the 1930s. The one-wheel store model was patented in 1870 and the two-wheel model was made in 1873. The renewed interest in fresh-ground coffee has produced many modern electric mills and hand mills and grinders. Reproductions of the old styles are being made.
