Wine has been historically produced in Kosovo. During the Yugoslav era, province of Kosovo was one of the biggest producers of wine in the federation. In 1989, Kosovo exported 40 million liters of wine to Germany alone. The political instability after the suppression of Kosovo's autonomy and the subsequent war led to a collapse of the wine industry and destruction of much of the winemaking infrastructure in the 1990s. Wine production has been recovering since. The main heartland of Kosovo's wine industry is in Rahovec where millions of litres of wine is produced. The main wines produced in Kosovo include pinot noir, merlot and chardonnay. Kosovo has recently been exporting wines to Germany and the United States.
