Riesling grown a stone’s throw from the cold Pacific? That alone makes this Radio-Coteau bottling a curiosity worth chasing. Eric Sussman planted a single estate acre of the grape in western Sonoma County, where his Sebastopol-based estate vineyard has been Demeter-certified biodynamic since 2018. It’s a dry, low-intervention take on a variety rarely seen this close to the California coast, raised with the same hands-off care as his cool-climate Pinot and Syrah. Think Eureka lemon, lime, and white peach with a chalky coastal lift rather than anything sweet or showy.
