Duckhorn Winery celebrates its 50th Anniversary this year spending half a century as more than an enduring milestone, but an iconic symbol of noteworthy wines interpreting Bordeaux varietals through a California lens, with Merlot foremost among them. Its founder Dan Duckhorn, an impassioned architect of Merlot, passed on March 25th at the age of 87, having been bestowed the title of “Mr. Merlot” by Frank Prial, journalist and wine columnist of The New York Times.

Dan completed his master’s degree in business administration at UC Berkley before advancing in his career as president of a vineyard consulting company in 1971. It is here that Dan fine-tuned his expertise in vineyard management, realizing the importance of rootstock and site-specific sites for grape growing. By 1973, he would move his family to Napa Valley and the narrative for Duckhorn Winery would begin. Dan and his wife Margaret, along with a few silent investors, founded Duckhorn Vineyards in 1976.

In 1977, Dan was inspired by the Right Bank wines of Pomerol and St Emilion during a trip to France with his close friend and winemaker Ric Forman. His intent was not to use Merlot as a blending grape but to elevate and refine its status in the US. While most of the valley were obsessed with Cabernet Sauvignon, Dan Duckhorn refused to apologize for his steadfast devotion for Merlot as he was seduced by its suppleness, complexity and affinity with food.

Ric Forman introduced Dan to brothers Sloan and John Upton, owners of Three Palms Vineyard in Calistoga. The property had three palm trees planted on the estate and was originally the residence of San Francisco socialite, Lillie Hitchcock Coit who passed in 1929. The Upton’s purchased the estate and planted vineyards in 1967 with strict standards in maintaining this hallowed property. These sun drenched, rocky volcanic soils became the source of Duckhorn’s single vineyard, luxury styled Three Palms Merlot. Around the same time, Dan met winemaker Tom Rinaldi who happened to be riding by on his motorcycle. Tom agreed to become the winemaker for Duckhorn crafting the 1978 inaugural release of Three Palms Vineyard Merlot and Three Palms Cabernet Sauvignon.

At the time, Dan didn’t have a facility or a lot of equipment, but with the use of a basket press, a couple of tanks and some new French Oak barrels they crafted two stellar wines with 800 cases of Merlot sourced from Three Palms Vineyards along with 800 cases of Cabernet Sauvignon from Stag’s Leap District and Howell Mountain. Dan introduced a vineyard-specific, age-worthy Merlot from Three Palms that gained international recognition and became the model for other producers in Napa Valley to emulate. Three Palms Vineyard became the soul of Duckhorn Winery. Their Merlot conveyed a personality that was silky, generous, structured and meant to be aged. Recently, Tom Rinaldi reported that the 1978 Duckhorn Three Palms Merlot was still showing well. By 1982, Tom and Dan produced Duckhorn’s first white wine with the release of a Sauvignon Blanc.

After the movie Sideways, Merlot seemed to fall out of favor but continued to gain acclaim under the Duckhorn Three Palms label. In 2014, Duckhorn Three Palms Merlot was named Wine Spectator’s 2017 Wine of the Year. By 2015, Duckhorn agreed to purchase the entire 83 acres of Three Palms estate. Given Dan’s avid love of fishing and waterfowl, a Mallard Duck became the emblem of Duckhorn.

In 2000, the Duckhorn Vineyard Estate House and Tasting Room were officially opened on their 10 acre estate in St. Helena. Since the founding of Duckhorn only four winemakers have shared in the esteemed role as director of winemaking including Tom Rinaldi whose tenure lasted 22 years, followed by Mark Beringer, Bill Nancarrow and their current winemaker Renee Ary.

In 2007, Duckhorn was sold to GI Partners, a San Francisco private equity firm and then again in 2016 to TSG. In 2024, it was acquired by Butterfly Equity based in Los Angeles for $1.95 billion.

Currently, Duckhorn has 11 wineries with 2,200 acres of estate vineyards. In 1980, they began acquiring Napa properties for their estate vineyard program ensuring a permanent source of top-quality fruit for their wines. By the mid-1980’s they introduced a second label named Decoy, offering quality at an affordable price. Fruit for Decoy is sourced from estate vineyards and established growers. In 1996, Goldeneye Winery was founded bringing Pinot Noir into the Duckhorn conversation, specifically from the cool, northern fog-driven confines of Anderson Valley—a region capable of producing wines with tension, acidity, and aromatic lift.

Calera was founded in 1975, by vintner Josh Jensen who sought out limestone‑rich soils in California much like those he had seen in Burgundy, planting Pinot Noir and Chardonnay on the rugged hills of the Mt. Harlan AVA in California’s Central Coast. It was acquired and integrated into the Duckhorn portfolio in 2017.

Kosta Browne began in 1997 when two restaurant coworkers, Dan Kosta and Michael Browne, pooled their tip money to buy grapes and make their first barrel of Pinot Noir; over the next decade they built a direct‑to‑consumer cult following. Their 2009 Sonoma Coast Pinot was named Wine Spectator’s Wine of the Year in 2011, and was acquired by Duckhorn Wine Company in 2018, securing its place as part of their ultra-luxury Pinot Noir program.

Sonoma‑Cutrer traces its roots back to 1973 when Brice Cutrer Jones built one of California’s largest luxury Chardonnay brands, releasing its first wines in 1981 and growing extensive estate plantings in the Russian River Valley and Sonoma Coast. Duckhorn acquired Sonoma‑Cutrer from Brown‑Forman in 2024 adding a top tier, illustrious Chardonnay to their enterprise.

Dan Duckhorn championed the belief that truly great terroir-driven wines stand the test of time. Over a lifetime, he cultivated enduring grower relationships while transforming the world’s perception of Merlot. His steady leadership brought consistency across the portfolio with a steady hand along with an attention to detail in all aspects of winemaking and vineyard management. Duckhorn continues to extend their recognition well beyond Napa’s original boundaries onto the global stage. When you finish your last sip, what lingers is not just pleasure, but the quiet certainty that you have witnessed a standard others will spend a lifetime pursuing.
