The Kosta Browne story is one of California wine's great underdog narratives. In 1997, Dan Kosta and Michael Browne, two waiters at John Ash & Co. restaurant in Santa Rosa, pooled $30,000 in saved tips to make their first barrel of Pinot Noir. They worked nights restaurant shifts and made wine during the day in a small Sebastopol facility, building a mailing list one bottle at a time. By the mid-2000s the wines had become benchmarks for richly expressive, fruit-forward California Pinot Noir, racking up 100-point Wine Spectator scores and a years-long waiting list. The label specialized in single-vineyard bottlings from Sonoma Coast, Russian River, and Santa Lucia Highlands.

Russian River Valley Pinot Noir — The appellation flagship; lush, layered, and the wine that built the cult following.

Sonoma Coast Pinot Noir — A multi-vineyard blend expressing the cooler, wind-swept coast.

Gap's Crown Vineyard Pinot Noir, Sonoma Coast — A single-vineyard bottling from the iconic Petaluma Gap site.

4-Barrel Pinot Noir — The most limited wine in the house, blended each year from just four standout barrels as a members' thank-you.

Russian River Valley Chardonnay — The cool-climate white that complements the Pinot program.

In 2009 Dan and Michael sold a majority stake to private equity firm J.W. Childs Associates while remaining at the winery. In 2018 Duckhorn Wine Company acquired Kosta Browne, marking the brand's entry into a larger Sonoma luxury portfolio. Winemaker Julien Howsepian took over the cellar in 2018 after a stint at Saxum and continues the single-vineyard Pinot Noir tradition. The Sebastopol winery and tasting room — the Sangiacomo Family's former Barlow Building complex — hosts seated tastings by reservation, with allocation-list members receiving priority on a rotating set of single-vineyard wines including the One Sixteen, 4-Barrel, and Sonoma Coast bottlings. The list remains famously oversubscribed.

Julien Howsepian
Head Winemaker

A first-generation American with a French father and Dutch mother, Julien Howsepian grew up in the Bay Area visiting wine-industry relatives in France, a connection that drew him to study viticulture and enology at UC Davis. He joined Kosta Browne in 2012 as one of twelve harvest interns and worked closely with co-founder Michael Browne, rising through production assistant, cellar master, and assistant winemaker before being named — at age 34 in 2019 — only the third winemaker in the winery's history. Building on Kosta Browne's reputation for benchmark California Pinot Noir, he has elevated its Chardonnay program, launched a sparkling wine, and extended the portfolio into Oregon's Willamette Valley and the grand cru vineyards of Burgundy.

Dan Kosta & Michael Browne
Co-Founders

Kosta Browne began with a tip envelope. In 1997, Dan Kosta — the general manager — and Michael Browne — the sommelier — were working at John Ash & Co. in Santa Rosa when they began squirreling away $10 a night from their tips. Two months later they had enough for a half-ton of Pinot Noir, a used barrel, and a hand-crank crusher, and made 24 cases. Word spread with the 2003 vintage, and their 2009 Sonoma Coast Pinot Noir was named Wine Spectator’s Wine of the Year. The “tip-envelope” origin remains one of California wine’s great underdog stories.
