Brassfield Estate Winery Sets a New Standard for High-Altitude Cabernet Sauvignon

The estate celebrates International Cabernet Sauvignon Day through the lens of uncompromising quality and High Valley terroir

Clearlake Oaks, CA – September 2, 2026 – Brassfield Estate Winery, recognized as one of the most successful rising voices in Northern California and the passionate ambassador of the stunning High Valley AVA in Lake County, stands out as a leader in its commitment to producing 100% estate grown, produced and bottled wines that are terroir-driven and of exceptional quality, with Cabernet Sauvignon a main focus, as it celebrates International Cabernet Sauvignon Day this September 3rd.

While Cabernet Sauvignon is a global staple, the distinct character of the High Valley AVA makes it a hidden gem defined by an altitude shared by only 1% of vineyards worldwide. Unlike many producers who source grapes from various regions, Brassfield Estate Winery offers a rarity in the wine world: a 5,000-acre family-owned estate where every grape is grown, produced, and bottled onsite.

This complete stewardship of the winemaking process, from the volcanic soil in the vineyard to the bottle on your table, creates a level of quality and transparency that is increasingly hard to find. By controlling every variable on the estate, Brassfield captures the true, vibrant expression of High Valley’s dramatic diurnal temperature shifts and cool marine breezes, resulting in Cabernet Sauvignon defined by remarkable depth and freshness.

"Being 100% estate grown, produced, and bottled allows us to oversee every step of the winemaking process, from the vineyard to the finished bottle," says Jonathan Walters, VP of Vineyard and Winemaking Operations. "That level of control ensures every wine is a true expression of our High Valley terroir and reflects the highest standards of quality, transparency, and authenticity. Cabernet Sauvignon is a cornerstone of our portfolio, as our unique high-altitude terroir allows us to capture the bold fruit, structured elegance and age-worthy complexity that truly sets our wines apart."

Brassfield’s tiered Cabernet Sauvignon portfolio showcases the diverse expressions of its high-elevation vineyards. The Estate Cabernet Sauvignon serves as the portfolio’s foundation, a balanced blend of select blocks that highlights the overall complexity and varied microclimates of the property. The Block 14 Cabernet Sauvignon is a single-vineyard expression from the High Serenity Vineyard; grown at elevations up to 2,000 feet in ancient lakeshore soils, it is celebrated for its intense concentration, floral aromatics, and significant aging potential. For the ultimate expression of the terroir, the Reserve Cabernet Sauvignon intricately blends the finest fruit from the volcanic Ridgeline Vineyard and High Serenity Ranch, resulting in a wine of exceptional structure and elegance.

As a rising voice in Northern California, Brassfield’s commitment to sustainable, high-elevation farming is setting a new standard for what Lake County wine can achieve. Whether you are looking for your next dinner party favorite or a bottle to cellar, Brassfield’s wines are available for purchase on the winery website and nationwide in fine dining restaurants and retailers, bringing the altitude and integrity of the High Valley to you.
