Sebastian Donoso, 37
Winemaker, Fringe Collective • Hopland, CAGoing to extremes
As he’s taken the helm of Fetzer Vineyards’ new
high-end line of wines, the Chile-born Donoso works
from the company’s Bonterra Organic Vineyards
property in Mendocino County. He launched the
Fringe Collective in 2018, which focuses on making
classic varieties from extreme vineyard sites, begin-
ning with Sonoma Coast Chardonnay and Central
Coast Pinot Noir. Donoso believes that the area’s
immense natural challenges give him the tools to
make wines of unbelievable depth and character, a
trial he’s met with enthusiasm and vigor.
