Rivers-Marie is a California wine producer known for its small-production Pinot Noir and Chardonnay wines from the Sonoma Coast. It was founded by Thomas Rivers Brown and Genevieve Marie Walsh, and made its first vintage of Pinot Noir in 2002. Rivers-Marie wines are sold exclusively through a mailing list, with annual production ranging from 60 to 600 cases per wine.
Thomas Brown got his start in the wine industry working under Ehren Jordan at Turley Wine Cellars. In 2002, he had the opportunity to purchase fruit from the respected Summa Vineyard, a 2-hectare (6-acre) site that was planted in 1978. Brown purchased the Summa Vineyard outright in 2010 and today produces two single-vineyard Pinot Noir wines from the vineyard, as well as single-vineyard Pinot Noir wines from Occidental Ridge Vineyard, Kanzler Vineyard and Silver Eagle Vineyard.
Rivers-Marie began making Chardonnay in 2007, and today makes single-vineyard wines from the Thieriot and Joy Road vineyards, as well as a generic Sonoma Coast cuvée. The winery also makes several Napa Valley Cabernet Sauvignon wines, including single-vineyard bottlings from Calistoga, St Helena and Oakville.
