About the Winery
Dew South is the project of William "Billy" Dewey and Hayley (McIntyre) Dewey. Billy learned the cellar side of the business at David Arthur Vineyards and Dakota Shy. Hayley studied wine and viticulture at Cal Poly San Luis Obispo and worked in brand management for premium wineries.
The wine is Cabernet Sauvignon from a small vineyard in the Oak Knoll District, between the Mayacamas and Vaca ranges at the southern end of the valley. French Clone 337 grows on the north side and FPS 30 on the south, on 1616C rootstock that lets the vines be mostly dry farmed. The wine ages about 18 months in French oak, a quarter of it new.
This is a very small, young label. The winery's website offers a contact form and social media links but lists no tasting room, address or visiting program, so Dew South does not host visitors. The day below takes you to three sought-after estates nearby that do, starting in the Oak Knoll District.
Tasting Fees
Dew South does not offer tastings.
Tasting fees as of September 2026. Wineries set and collect their own fees, and they change from time to time.

Since Dew South does not host visitors, this day takes you to three sought-after estates nearby that do, starting in the Oak Knoll District. Silverado Resort, at the foot of Atlas Peak, and Andaz Napa, a boutique Hyatt in downtown Napa, are each about 15 minutes from the first stop. The day runs about six and a quarter hours, and extra time can be added by the hour.

About 15 minutes away. A husband-and-wife label from a former Spottswoode winemaker, pouring heritage whites and vineyard-designate Cabernet at Arrow&Branch in the Oak Knoll District. The Zeitgeist Tasting Experience is $85; we allow about an hour. Private tastings by reservation.

About 20 minutes away. Chris Carpenter's organically farmed Mount Veeder estate above the fog line, where a walk at the Mt. Brave Overlook comes before the seated tasting. The Mt. Veeder Experience is $175, 90 minutes or more, for 2 to 6 guests. By reservation; the meeting point is confirmed with the booking.
1:35 · Lunch at Bistro Don Giovanni
About 15 minutes away. Lunch at Bistro Don Giovanni, an Italian restaurant among the vineyards on Howard Lane, a valley favorite for more than 30 years, open daily from 11:30 a.m. Prefer a picnic? We can arrange a catered picnic at a winery that allows one; the cost is quoted when you book.
3:05 · Altamura Vineyards & Winery
About 20 minutes away. A family ranch in quiet Wooden Valley, settled by Karen Altamura's family in 1855, with caves and a stone winery. The hosted tasting of four estate wines with a meat and cheese platter is $75. By appointment through the winery.
4:05 · Back to your hotel
Back by about 4:20 p.m., about six and a quarter hours after pickup.
About $335 per person in tasting fees for the three wineries, paid directly to each winery.
