Vin jaune has a _________ crust and is aged for ________.

Vin jaune, a famous wine from the Jura region in France, is notably characterized by its unique aging process and the type of crust that develops during maturation. The correct choice highlights that vin jaune has a yeast crust, which forms as the wine ages under a film of yeast, similar to what occurs with sherry production. This crust, known as "voile," helps to protect the wine from excessive oxidation while allowing for some development of complex flavors.

The aging duration of vin jaune is also essential to its identity. It is aged for 6 years and 3 months in oak barrels, a period that contributes significantly to its distinctive nutty and oxidative qualities. This lengthy aging process is crucial to developing the wine's unique profile, which includes intense flavors and aromas, as well as a golden color. The combination of the yeast crust and the extended aging period are defining features of vin jaune that distinguish it from other wines.
