A method of producing nootkatone by laccase catalyzed oxidation of valencene. Valencene and a composition having laccase activity are reacted in the presence of an oxygen source, at a valencene concentration greater than 0.1 %, to form valencene hydroperoxide. Optionally, a mediator and/or a solvent at a concentration that maintains lactase activity may also be included. The valencene hydroperoxide is degraded to form nootkatone, and nootkatone is then recovered. The method produces nootkatone in commercially viable yields.
