The Lake County appellation is situated next door to the Napa Valley yet has a very different climate. It is much warmer and lacks the coastal influence that its more famous neighbor basks in. Lake County has mostly been known in the past for its bulk wine production, yet a new generation of winegrowers are beginning to figure out what the area’s different microclimates are capable of. These quality-minded producers are making smaller volumes of elegant wines, like those of Prima Materia.
