Tour The Ranch
The Stage Coach Stop Tasting Room
When you come to visit our tasting room, you’ll trek down the 2-mile drive from our front gate at Spruce Grove Road. The road follows Asbill Creek, named after the first family of settlers who made the valley their home in the late 1850's. Our tasting room is located on a site that once was a stagecoach stop, and the cozy cabin sits among century-old Valley Oak trees.
Wine Tasting
We are open for tasting daily; Sun-Thurs from 11:00am to 4:30pm, and Fridays & Saturdays from 11:00am - 7:30pm our friendly staff will introduce you to our current releases. (Closed Thanksgiving Day and Christmas Day)
The tasting fee is $20 per person; the charge is waived with purchase. Tasting is complimentary for Club Members.
Picnic Area
We invite our Club Members and other customers to enjoy the oak-shaded picnic area that surrounds the tasting room, the perfect spot for a relaxing lunch! Create a grazing board from our selection of meats, cheeses, crackers and spreads, or select some Ranch-Raised beef and grill your own meal on our BBQs.
