The renowned Napa Valley winery's western Sonoma outpost is a good place to learn about biodynamic growing techniques while tasting crisp Chardonnays and earthy Pinot Noirs. Phelps wines have always garnered praise for their expression of terroir (the land), and the ones made here have a composed, ascetic quality that perfectly mirrors the rugged Sonoma Coast. You can almost taste the vines sending out long roots to find nutrients in the rocky, mineral-laden soil. If prompted, your pourer may regale you with descriptions of biodynamic strategies that involve timing vineyard activities to the waxing or waning moon and compost preparations that incorporate yarrow, stinging nettle, and other herbs. Sonoma Coast wines predominate the $20 tasting list—the estate-grown Pinot Noir is a standout—while the $35 tasting list includes a few exceptional Napa Valley selections.
