Which is the only U.S state that grows coffee beans?

Hawaii.

There are several coffee farms throughout the island of Hawaii. However, the state is known for its Kona coffee. The Kona "coffee belt" is about 2 miles wide and is located between 200 and 700 feet above the sea level on the slopes of the Mauna Loa volcano. The region, which is characterized by black, volcanic soil, has the perfect conditions for the coffee tree, and produces some of the finest coffee beans in the world. Coffee harvesting in Hawaii occurs all year round, although the highest production is between late summer and early spring.
