The main grapes of the region are Chardonnay (known locally as Melon d'Arbois), Savagnin (known locally as Naturé), Poulsard, Pinot noir and Trousseau. Chardonnay and Pinot noir clippings were brought to the region from Burgundy during the Middle Ages and were used limitedly among the 40 other grape varieties that were prevalent in Jura for most of its winemaking history. Towards the end of the 20th century both grapes began to increase in popularity, particularly the Chardonnay vine which now accounts for nearly 45% of all Jura plantings and is valued for its good sugar levels and early ripening.
