Full Description

Tucked within the renowned northwestern corridor of Philo, Vonarburg Vineyard is an exceptional 2.5-acre boutique vineyard known for its small-scale production and outstanding fruit quality. Surrounded by some of Anderson Valley’s most respected vineyard sites, this hidden gem benefits from a prime location that combines cool coastal influences, fertile soils, and a long growing season ideal for cultivating premium wine grapes.

Carefully farmed by Norman Kobler, the vineyard is dedicated to producing high-quality Riesling and Pinot Noir that reflect the distinctive character of Anderson Valley’s cool-climate terroir. Its limited acreage allows for meticulous vineyard management, with close attention paid to vine balance, fruit development, and overall vineyard health.

The region’s characteristic morning fog, warm afternoons, and cool evenings contribute to gradual ripening, helping preserve natural acidity while enhancing aromatic complexity and flavor concentration. These conditions are particularly well suited to Riesling and Pinot Noir, two varieties that thrive in cooler growing environments.

Riesling from Vonarburg Vineyard is often valued for its vibrant acidity, expressive aromatics, and mineral-driven character, while Pinot Noir showcases layers of red fruit, floral notes, elegance, and refined structure. The vineyard’s exceptional fruit quality has attracted the attention of respected producers who seek grapes capable of expressing the purity and complexity of Anderson Valley. Through careful farming and a commitment to excellence, Vonarburg Vineyard continues to stand out as one of the region’s most distinctive boutique vineyard sites.
