In this episode of The Vint Wine Podcast, we sit down with Julien Howsepian, lead winemaker at Kosta Browne, one of California’s most acclaimed producers of Pinot Noir and Chardonnay. Julien shares how his path led from UC Davis to becoming a key figure in American fine wine and explains what makes the Kosta Browne portfolio so distinct—from Russian River to Santa Rita Hills, and even Burgundy.

🍇 Julien’s journey from economics major to head winemaker—and how a brewery in Pennsylvania helped shape his approach to winery logistics and efficiency.
🌍 The regional diversity of Kosta Browne’s portfolio, including Russian River, Sonoma Coast, Anderson Valley, Santa Lucia Highlands, Santa Rita Hills, Oregon’s Willamette Valley, and Burgundy.
🍷 What makes wines from Treehouse, Gaps Crown, Keefer Ranch, Shea, and Cerise vineyards stand out—and how Kosta Browne brings out their unique voices.
🛠️ The role of fermentation vessels—stainless steel, oak, and concrete—in shaping texture, aromatic lift, and style across the range.
🔬 Why Kosta Browne focuses on purity, place, and structure, and how Julien uses small-lot fermentation and non-interventionist winemaking to highlight terroir.

A must-listen for fans of Pinot Noir, site-driven winemaking, and the evolution of modern California wine & beyond.
