Loam Single Soil Wines is a Healdsburg, Sonoma County, venture developed by Clay and Carrie Mauritson. Their focus is to make limited release Cabernet Sauvignon from some of their family’s best vineyards. The Mauritson family has been farming in the area since the 19th century and since the 1990s Clay Mauritson has been making his own wines. He is the winemaker for Loam Cabernet Sauvignon. The Mauritsons note that “most world-renown viticultural regions consist of loam soils (and) Sonoma County is no exception. Within the loam family of soils is an array of classifications, or ‘series,’ identified and catalogued by four distinctive features: compositions, depth, slope and geographical location.”
