Burgundy's terroir-driven wines are shaped by its diverse geography and signature grape varieties of Pinot Noir and Chardonnay. The region is divided into sub-regions like the Côte d'Or and Chablis, each producing uniquely characterized wines. Burgundy also has a strict hierarchical appellation system denoting a wine's quality and terroir from broad regional AOCs to the most prestigious Grand Cru level. Producers play a key role in crafting Burgundy's reputation for elegant and complex wines showcasing each vineyard's individual character.
