English brown oak isn’t actually a separate species; rather it’s the result of a fungus that has infested the heartwood of a European oak and turned it a rich, dark brown. When that process doesn’t deteriorate the wood itself, it’s sliced to produce this highly desirable, deep brown veneer. Available in flat or quarter cuts as well as rift cut, which produces an exquisite flake pattern when sliced across the wood’s broad medullary rays.
