Things I’ve learned about american oak (and/or oak in general).
One caveat: I’ve never used american oak in any of my wines so far. But I like to understand interesting/controversial/possibly useful wine topics, and American Oak qualifies on at least one point there!
For a long time, in the early 1900s, 1800s and earlier, oak barrels were the storage/transport vessel of choice. The containerized cargo of that era. In the U.S., and elsewhere, american oak was used, of course. This lead to the great depletion of american oak trees, esp older american oak trees, by the early/mid 1900s.
Apparently, barrels made from 80-100 year old american oak trees were the most desired/prized for wine aging (and other similar uses). But, alas, those trees have all been cut down long ago. Realizing the situation, a program was set up to replant Am oak trees in the mid/early 1900s. Also, fortunately, we moved on to other transport storage vessels.
It’s only now that the AmOak trees that were replanted so long ago are beginning to enter the prized 80+ year old zone. Perhaps there will be a resurgence of Am Oak usage over the years. I suspect we lost a lot of expertise in oak harvesting/drying/toasting/etc from the 1800/1700s era. I’ve heard a number of folks say they believe this, the loss of 80+ yo trees and barrel making expertise from that era, is the root of the complaints we have about AmOak.
Another semi-unrelated comment about oak was from René Dauvissat in 2002. He said oak is very important to Chablis (I’m not saying he used AmOak tho, of course!). I believe this quote…I was fortunate to meet & barrel taste with Vincent Dauvissat a bit later than this, who made similar comments. They feel/felt that the synergy of air and the wood adds character to the wine, and helps to soften the wine…that without oak, Chablis would be too hard and too austere (referring to Chablis in the 1990s and earlier). Given that there has been a seismic shift in the ripeness and structure of grapes and wine, between the 90s/earlier and now, perhaps oak no longer has an appropriate/prominent place in ‘terroir’ based winemaking. My wines, including my Chardonnays, rarely see any new oak elements these days, because it just doesn’t seem to fit imo. I haven’t nailed my foot to the floor on this tho.
