Surrounded by the cooling waterways of the Sacramento River Delta is the rich farmland of the Clarksburg appellation. Weighted drawbridges and swing bridges give access to the lush lands bordered by Interstate 5 on the east and the Sacramento Deep Water Channel on the west. Small towns dot the riverside and wine grape vineyards nestle among the farmlands of row, field and orchard crops. The northern appellation border parallels the town of Freeport, while the southern border runs along Twin Cities Road, extending to the Sacramento Deep Water Channel.

The Clarksburg appellation, located in BATF district 17, encompasses 56,900 acres over an area 16 miles long and eight miles wide. The appellation currently has approximately 10,000 acres of vineyards.

Warm summer days and cool nights typify the climate in the Clarksburg appellation during the long, dry growing season. These prime conditions allow for the growing of over 25 varities of wine grapes. They include: Chardonnay, Merlot, Chenin Blanc, Sauvignon Blanc, Petite Sirah, Syrah, Zinfandel, Viognier, Cabernet Sauvignon and Pinot Gris.
