Question: Are the oak barrels used for aging the same in Bordeaux & Burgundy?
Answer: Almost but not quite. Bordeaux casks are usually longer and narrower shaped holding 225 litres while Burgundy usually are slightly fatter and shorter holding 228 litres. Curiously both places say each one produces 300 bottles of wine. Size is a difference but the oak comes from different French forests as well with the main ones selected from Allier, Bertrange, Jupilles, Limousin, Nevers, Troncais, and Vosges. The tightness of the grain of the oak and the amount of toasting is another variable in both regions.
