The term musque refers to an especially aromatic version of a grape variety. (The word “musk” is an ancient term for perfume). The best example is sauvignon musque which is more floral and fruity than its sister sauvignon blanc. Though sauvignon musque is still relatively rare, plantings are on the rise in California. Already many of the best sauvignon blanc wines are blends of sauvignon blanc with sauvignon musque.
