Matthews was established in Woodinville, near Seattle, in 1993 by Matthew Loso. In 2008 the Otis family of Woodinville, who had already owned a financial share of the winery, bought out Loso and by 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. Besides making Mathews label wines, the Otis family, which includes several adult sons who help run the business, have created an ultra premium winery and label called Tenor. The Matthews label offers a full portfolio of wines, including a Claret, Syrah, Cabernet Sauvignon, Chardonnay, Sauvignon Blanc and red blends.
