Well, AFAIK no wine integrates new oak without bottle aging.
Before the visit to Luis Pato, I had seen this intriguing picture on his site:
The cluster on the left is from grafted Baga vines, the cluster on the right is from ungrafted.
During the visit, Pato said that he doesnt want the taste of oak in his wines, but wants to maximize the natural micro-oxigenation benefits that new oak has on the grape tannins (he is an engineer and an enologist, and said with conviction that new wood and grape tannins polymerize together into something "softer" than the sum of the parts).
He also said that, with his ungrafted Baga, he can always use 100% new wood because the berries are smaller and the skin to juice ratio so high that the must can absorb the new oak flavor in
barrel (not bottle). For the sake of comparison, he said that Touriga Nacional, generally considered a tannic grape, is less "structured" than Baga, and cannot "handle" 100% new oak without acquiring its flavors, even in the most powerful vintages. So, every year, with every variety, both for blends and varietals, Pato has to decide what is the maximum % of new oak that he can use to get the benefits without the taste.
Looking back, I think I conflated the above two inputs to mean that the more tannic a grape must is, the more it will absorb the
flavor of new wood. I imagine that's simplistic, and that phenolics play a bigger, or perhaps the only, role in absorbing wood flavor. You and Joe have a better handle on this, so my question is: do tannins play a role in the absorption of oak flavor (by binding with oak flavor molecules) or is that the prerogative of phenolics?
