 mill. In 1876, it was moved to its present location by P S Bos. In September 1935, one pair of sails was streamlined on the Fok System and one pair of Bilau sails was fitted. In 1946, the Friese Molencommissie (English: Frisian Mills Commission) estimated that the mill would cost ƒ5,000 to restore. By this time the mill had lost a pair of sails. The mill was sold by Jaap Bos to Jan van Dieren in 1964. He used the ground floor of the mill as a coffee house, but left the machinery in the mill intact. The former engine house was converted to a kitchen and toilet. A further restoration was undertaken in 1980-81. The sails were replaced after a twenty year absence. A further restoration was undertaken in 2002-03. Koffiemolen is the only windmill on Terschelling.
