About THE GRADE Cellars
THE GRADE Cellars is best handled as an appointment-only or limited-access Napa winery unless the current official source clearly establishes broader public access. The Wino Notion page can celebrate the producer and its wines while making the reservation requirement the first practical planning detail. A winery name, vineyard location or online shop does not by itself establish a public tasting room.
A useful visitor profile should explain how to request the experience, how far ahead travelers should plan and whether the address is supplied only after confirmation. The winery's live reply should control available days, fee, duration, wines included, party limit, purchase waiver and cancellation policy. Any restriction to members, collectors, referrals or allocation customers should appear prominently rather than being buried in internal notes.
The page should avoid turning estate features into universal amenities. Caves, gardens, vineyard views, food, outdoor seating and production tours may exist without being included in every appointment. Children, non-tasters, pets and service animals should be discussed directly before booking, and all members of the party should be disclosed. Guests should save the confirmed driving instructions because private Napa properties may not use the address shown in older directories.
THE GRADE Cellars can be a strong choice for travelers who prefer a quieter hosted conversation and are comfortable structuring the day around a confirmed appointment. It should not be promoted as a spontaneous stop. Before publication or travel, the official reservation page or written confirmation should control the final address, operating days, experience name, price, arrival instructions and guest policies.
Tom Thornton and Brenda Mixson's 1997 Calistoga ranch, named for the historic toll road Robert Louis Stevenson wrote about above their vines.

Bought without any plan to make wine,the couple purchased their Calistoga ranch in 1997 purely as an investment, years before they ever considered starting their own label.

Named after a Robert Louis Stevenson book,THE GRADE and its Sea-Fog Sauvignon Blanc both take their names from Stevenson's The Silverado Squatters, describing the old toll road above the estate.

A 99-point score from Robert Parker,winemaker Thomas Rivers Brown, who joined in 2011, crafted a Kingly Project Cabernet Sauvignon that earned a 99-point rating from critic Robert Parker.
"Wino Notion likes the potential for a personal, quieter experience at THE GRADE Cellars. The appointment-led format can reward careful planners when the winery confirmation controls the address, fee and guest policies."
