The primary sector is based on small to medium-sized family-owned dispersed units. 53% of the nation's area is agricultural land, 41% forest and forestry land, and 6% for others. The arable land is mostly used for corn, wheat, pastures, meadows and vineyards. It contributes almost to 35% of GDP including the forestry sector. Wine has historically been produced in Kosovo. The wine industry is successful and has been growing after the war. The main heartland of Kosovo's wine industry is in Orahovac, where millions of litres of wine are produced. The main cultivars include Pinot noir, Merlot, and Chardonnay. Kosovo exports wines to Germany and the United States. During the "glory days" of the wine industry, grapes were grown from the vineyard area of 9,000ha, divided into private and public ownership, and spread mainly throughout the south and west of Kosovo. The four state-owned wine production facilities were not as much "wineries" as they were "wine factories". Only the Rahovec facility that held approximately 36% of the total vineyard area had the capacity of around 50 million litres annually. The major share of the wine production was intended for exports. At its peak in 1989, the exports from the Rahovec facility amounted to 40 million litres and were mainly distributed to the German market.
