Hundred Acre

Jayson Woodbridge was born in Toronto, Canada, and came to wine as an investment banker. He arrived in Napa Valley in 1999 with no winemaking experience and founded Hundred Acre in 2000. The Kayli Morgan vineyard, now called Morgan's Way, was purchased in August 2000, and with the 2000 harvest approaching, Barbour, who had redesigned the vineyard in 1996 for a former owner, suggested Woodbridge meet consultant winemaker Philippe Melka. Melka crafted the first Hundred Acre bottling, the 2000 Kayli Morgan Cabernet, at nearby Rombauer winery; production moved to Quintessa in 2001, and Woodbridge himself assumed the role of winemaker in 2002. The name is not a reference to Winnie-the-Pooh but a reminder of Woodbridge's youth as a long-distance runner in the woods near his childhood home.

• Founded 2000; the Kayli Morgan vineyard, now Morgan's Way, was purchased in August 2000
• Philippe Melka made the 2000 Kayli Morgan Cabernet at Rombauer; production moved to Quintessa in 2001
• Woodbridge assumed the role of winemaker in 2002
• Woodbridge also created the under-$20 brands Layer Cake, Cherry Pie, and If You See Kay, all sold to Vintage Wine Estates in 2018

Founder Jayson Woodbridge owns Hundred Acre and is the founder and owner of the St. Helena-based Hundred Acre Wine Group. Jayson Woodbridge is the winemaker. His son Cameron was appointed cellarmaster at Fortunate Son in 2023 and, as of August 2024, was his father's assistant winemaker. Woodbridge has two other wineries: Fortunate Son, founded in 2018 at the former David Fulton Winery in St. Helena, and Summer Dreams, which makes Chardonnay and Pinot Noir from cool-climate Sonoma Coast vineyards.

Hundred Acre's signature wines are three organically farmed estate single-vineyard Cabernet Sauvignons. Morgan's Way (formerly Kayli Morgan) lies between St Helena and Calistoga on the eastern side of Silverado Trail close to Bale Lane, with 3.64ha planted entirely to Cabernet Sauvignon. Ark, below Glass Mountain in St Helena, was acquired in 1999; its 18.21ha site has 5.26ha planted to six clones of Cabernet Sauvignon on steep south-facing slopes, on ground of red soil, black obsidian rock, and volcanic pebbles, and the first Ark wine was made in 2005. Few and Far Between, the former Pickett Road vineyard in Calistoga acquired in 2008, surrounds the Woodbridge home and shares a fence line with Eisele Vineyard; its 2ha are planted to 90% Cabernet Sauvignon and 10% Cabernet Franc, and the first bottling debuted with the 2008 release.

• Morgan's Way: 3.64ha of Cabernet Sauvignon east of Silverado Trail, south of Bale Lane
• Ark: 5.26ha planted within an 18.21ha site below Glass Mountain; acquired 1999
• Few and Far Between: 2ha in Calistoga, 90% Cabernet Sauvignon and 10% Cabernet Franc; acquired 2008
• Organic mushroom compost is spread in the estate vineyards, and vines are culled to one cluster per shoot

Woodbridge has expanded his Napa Valley holdings through a run of purchases. He acquired the historic David Fulton Ranch in St. Helena in 2020 and, in 2022, an 18-acre vineyard on Calistoga's Larkmead Lane, now called True Romance Vineyard. In 2024 Hundred Acre purchased Madrigal Vineyards, a 10-acre property between Calistoga and St. Helena with 8 acres of planted vineyards. Hundred Acre Wine Group then acquired the 286-acre Kelly Fleming Wines property at 2339 Pickett Road in Simmons Canyon, with 12 acres of planted vineyards, a 5,000-square-foot stone winery, and 7,000 square feet of caves, next to Hundred Acre's 115-acre ranch and its Few and Far Between Vineyard. Hundred Acre said the acquisition would allow for more barrel fermentations in the caves, and Woodbridge planned to use the Kelly Fleming fruit to expand Hundred Acre's production by a few hundred cases.

• 2020: the historic David Fulton Ranch in St. Helena
• 2022: an 18-acre vineyard on Calistoga's Larkmead Lane, now True Romance Vineyard
• 2024: Madrigal Vineyards, 10 acres with 8 acres planted
• 2024: the 286-acre Kelly Fleming Wines property, with 12 acres of vines, a stone winery, and caves

Each Hundred Acre bottle carries a 24-carat gold ring fired into the glass rim. Woodbridge states that the caves' air-treatment system was designed for NASA and used on the International Space Station; ozone gas and ozonated water are also used to clean surfaces and drains. Woodbridge had upright elliptical oak tanks custom-designed for fermentation, ageing is done in 225-litre barriques, 500-litre puncheons, and 400-litre hogsheads, and once bungs are sealed no wine is removed for 30 months. Decanter describes the single-vineyard Cabernets as distinct and elaborately constructed. Alcohol levels are often between 15% and 16%. Beyond the three single-vineyard wines, blends and experimental-ageing bottlings have included Dark Ark, Deep Time, Precious, Wraith, Wraith Crypt, and Fortification, a Port-like Cabernet Sauvignon fortified with brandy distilled from Cabernet Sauvignon grapes. Wraith is a blend of all three estate single vineyards.

• Made in the underground Ring winery beneath Ark vineyard since 2005
• Ageing in 225-litre barriques, 500-litre puncheons, and 400-litre hogsheads; no wine removed for 30 months once bungs are sealed
• Single-vineyard Cabernet Sauvignons from Ark, Few and Far Between, and Morgan's Way, plus Dark Ark, Deep Time, Precious, Wraith, Wraith Crypt, and Fortification
• The Ancient Way Shiraz from Barossa Valley was discontinued after 2010

Hundred Acre sells through a waiting list; the winery's website invites buyers to sign up "for future access to wine offerings and updates." Wines bought outside the winery and its authorized distributors and importers do not have guaranteed provenance, and the winery lists its distributors by US state. The Ring winery is not open to the public, and one third of production is reserved for restaurant clients. In 2024 the brand sold bottles for $750 or more.
