This hand crafted peppermill is turned from Ailanthus. Ailanthus is also known as "Tree of Heaven". This is a unique species that has its origins in Eastern Asia. Large ornate clusters of small yellowish-green flowers are produced on the trees in June. In summer single seeded winged fruits are produced on the female trees. Individual trees may produce 315,000 plus seeds annually. Mature trees grow to a height up to 100 ft with a diameter up to 3 ft. The peppermill is fully adjustable with just a twist of the top knob below the spring. This will make your grind from fine to coarse. Fill with your favorite pepper corns. Has food grade finish.
