Tenor is a prestige label owned by the Otis family of Washington, who also own Matthews winery in Woodinville, near Seattle. Matthews was founded in 1993 by Matthew Loso and in 2008 the Otis family, who already owned a financial share of the winery, bought out Loso. In 2012 the Otis family, headed by Cliff and Diane Otis, bought out the remaining owners to become sole proprietors. Matthews Cellars was one of the first wineries in Woodinville, which is now home to nearly 100 wineries. The Otis family includes several adult sons who help run the business and who have created Tenor, which makes a Bordeaux-style blend, Syrah, Chardonnay Malbec, Merlot, Cabernet Sauvignon Blanc and other wines.
