Q

Oxygen Transfer Rates among American and European Oak?

A

Since French oak must be split, only 20 to 25% of the tree can be utilized.

American oak may be sawn, which makes it at least twice as economical.

Traditionally American oak is left outside to dry, and not kiln dried like traditional French would be.

American Oak has a higher OTR mainly due to the fact that it is cut.

What is the Gibbs-Marangoni Effect?

Long legs/tears = more evaporation due to a higher alcohol %
