Aging potential varies depending on the appellation level and the vintage. A regional Bourgogne is generally best enjoyed within 3 to 5 years of the harvest. A premier cru can be cellared for 8 to 15 years, depending on the producer and the vintage. Grand crus, on the other hand, can age for several decades: some Gevrey-Chambertin or Chambolle-Musigny reach their peak after 20 to 30 years in the cellar. Sunny vintages such as 2015, 2019, and 2020 generally offer better aging potential thanks to their fine concentration of tannins and natural acidity.
