at certain points during this time the wine is not necessarily in the cask. After the allotted time, only about 62% of the original wine remains. The vin jaune is then bottled in special squat bottles that hold 62 cl (21 ounces), called clavelins. Historically the bottle size alludes to the amount of wine left over after six years of aging and evaporation. Wine regions The Appellation d'origine contrôlée regions permitted to produce vin jaune include Château-Chalon AOC, Arbois Vin Jaune AOC, Cotes du Jura vin Jaune AOC and Vin Jaune de L'Etoile. Those protected "appellations" have existed since 1936. There are also a few other vin jaune-style wines made in France outside the Jura region, such as Gaillac. The term vin de voile referring to the yeast film, thus indicates this style of wine. Wine style and serving Vin jaune is often served at cellar temperature 13–15 °C (55–60 °F) and the wine is sometimes decanted, exposing it to more oxygen prior to serving in order to stimulate the wine's unique aromas. The wine can be paired with savory food dishes with local Jura cuisine often including chicken recipes where the wine is cooked with the chicken itself and as a sauce component. Another common pairing is the local Comté cheese that is produced in the Franche-Comté region. La Percée du Vin Jaune A festival called La Percée du Vin Jaune (Opening of the Yellow Wine) is held in the last week of January or the first week of February each year to celebrate release of the newly released vintage, which due to the legal requirements for aging will be the one harvested in the autumn seven years earlier. Recent events, including tasting sessions, have attracted over 30,000 visitors. Each year, a different venue is chosen.
