Helen Turley and her husband John Wetlaufer are one of Napa Valley’s most famous couples. Both are winemakers and entrepreneurs who between them have consulted or worked for a significant number of the valley’s most prestigious wineries. They founded their own winery, Marcassin, in 1990 in the Russian River Valley where they cultivate fewer than 20 acres planted to Chardonnay and Pinot Noir. Marcassin Chardonnays are consistently among the finest produced in California – or anywhere in the world, according to Robert M. Parker J. – and the couple is also now producing highly-rated Pinot Noir. Parker has written that Turley and Wetlaufer “continue to rank at the top of the short list of producers making the world’s most prodigious, complex wines.” The total annual production at Marcassin is fewer than 2,000 cases and the wines are distributed only through the winery’s mailing list.
