Jura is a wine region in eastern France, known for producing distinctive wines with unique flavors and aromas. The region is located between Burgundy and Switzerland and shows some similarities with both regions in terms of winemaking traditions and grape varieties used.
Jura wines are mainly made from four grape varieties: Savagnin, Chardonnay, Poulsard and Trousseau. Savagnin is a white grape variety used to make the region's most famous wine, Vin Jaune. This wine is aged for at least six years in oak barrels and has a distinctly nutty flavor with notes of spice and citrus. Chardonnay is used to make the region's white wines, which are crisp, dry and have aromas of green apple, pear and lemon. Poulsard and Trousseau are red grape varieties that produce light wines with aromas of red fruits and spices.
One of the unique winemaking techniques used in the Jura is sous voile aging, where the wine is kept in oak barrels and allows a layer of yeast called flor to develop on the surface. This technique results in a distinct flavor profile and aroma that is characteristic of Jura wines.
