The difference between French and American oak

All trees have medullary rays, structures that resemble spokes, radiating from the center of a tree to the outer layer (bark). These rays conduct sap and also create a natural point of separation within the trunk of the tree.

French oak must be split along the medullary rays so that the ray remains parallel to the width and length of each stave. Splitting the logs in this manner is the best way to ensure that the staves will be water tight.

American oak is less porous than French oak; because the heartwood is denser, the medullary rays are not as crucial to the process. This allows stave makers to focus on efficiency through quarter sawing logs instead of splitting them.
