Me too.

Sorry can’t help with the species of the trees, but it is white oak. From the wine side of things I do know the two main barrel producing areas. The barrels: new or used, are generally from either American or Europe. In America the trees are from regions like Minnesota and Iowa, while the European barrels mainly come from the Troncais, Vosges & Nevers forests in France.
