The Arroyo Seco wine-growing region in the Salinas Valley may be relatively small in acreage but it’s big in flavor. This, thanks in large part to the loamy soil that covers a base of river stones, known as Greenfield Potatoes, deposited over thousands of years by the Arroyo Seco River. The three to four inch cobblestones retain the heat of the day which is absorbed by the vines during the region’s much cooler nights. A unique terroir that produces great tasting wine.
