MATTHIASSON is a family endeavor, the effort of Steve and Jill Klein Matthiasson, and our two young sons. We have both had life-long careers in sustainable agriculture, and we apply those ideals of balance, restraint, and respect for the individual—and for the whole—to our wine. Our production is simple but careful. This concept is central to the tradition of viticulture and winemaking. Respect for this tradition forms the core of our work. To that end, our hands literally touch every vine and every bottle.

As a vineyard consultant Steve teaches and makes decisions, such as when to water and how to prune, on vineyards throughout Napa and Sonoma. Steve’s current clients include Araujo Estate, Spottswoode, Chappellet, Hall, David Arthur, Robert Sinskey Vineyards, Stag’s Leap Wine Cellars, Long Meadow Ranch, Trefethen, Limerick Lane, and others. On our own vineyards, however, Steve cares for the vines with his own hands, driving the tractor at night, and working with the crews on Sundays.
With the non-profit Community Alliance with Family Farmers, Jill organized farmer groups throughout the state, lobbied for sustainable agriculture programs, and facilitated education on farmers' markets, community supported agriculture, and practical skills like compost-making or cover cropping. Now, in addition to raising two boys and running the family business, she serves on the Napa Farmer’s Market Board, teaches “cooking from the garden” to elementary school kids, and makes the jams and jellies from our home-grown fruit for our wine club.
As a family we eat together, make wine together, and grow food together. We value the land, and love to produce grapes, wine, and the sweetest, juiciest, organic, tree-ripened peaches and plums you've ever tasted.
The work and the attention to detail is never-ending. The result is MATTHIASSON.
