The Cosumnes River appellation, located in northwestern Lodi, has 54,700 acres total, of which 3,500 are under vine. With elevations dipping to sea-level and rising to 48 feet, the Cosumnes River appellation has a ‘relatively cool and windy growing season’ and ‘young, alluvial soils and low-elevation terrain.’ These factors contribute to persistent maritime and inland fog, creating a cooler climate than other Lodi appellations. Not surprisingly white varieties such as Chardonnay, Sauvignon Blanc and Viognier are dominant here.
