Situated just off Valley Ford Road, DeBernardi Dairy is a local dairy with a little extra — it also produces its own cheese, a raw-milk hard cheese marketed under the name Two Rock Valley. It's sold in a young version and in one that's aged for more than 12 months. Both are modeled after cheeses from the owner's Swiss-Italian homeland. The aged version is dryer, sharper, and perfect for grating. The younger version has a nutty flavor, similar to that of a Swiss cheese. Both are priced at $15 per pound. You can purchase the Two Rock Valley cheeses at various farmers' markets throughout Sonoma County.
