About Us / Matthiasson History: MATTHIASSON is a family endeavor, the effort of Steve and Jill Klein Matthiasson, and our two sons. For our wine, we have selected a small number of exceptional vineyard sites to make unique wine of the highest quality, with production that 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.
