Rochioli wines are some of the finest and most sought after wines in all of California. If you love wine, this is a must visit.
As for the rest of the experience, Rochioli isn't a winery you visit to take in lush gardens and amazing architecture. The grounds are nice and well kept but not a must see. They do have a gorgeous view, particularly in Autumn, of the vineyards off their tasting room patio which may be ideal for small group picnics.
