Final answer:
New oak barrels impart more flavor to wine than old ones because they contain greater amounts of flavor compounds that have not yet been extracted.
Step-by-step explanation:
Yes, new oak does indeed impart more flavor to a wine than older oak. When wine is aged in new oak barrels, the wood has a larger amount of flavor compounds, such as vanillin and tannins, that have yet to be leached out by previous batches of wine. As a result, the wine can absorb more of these flavors, giving it a more pronounced oak character. Conversely, with each subsequent use, an oak barrel will impart less flavor to the wine because more of its flavor compounds have been extracted in previous uses.
