The Stuhlmuller Vineyard is located in northern Sonoma County, at the confluence of Chalk Hill, Alexander Valley, and Russian River Valley. It lies at the appreciably cooler southwestern edge of the Alexander Valley, with the Russian River running along its eastern border.

On the western edge of the property is the Chalk Hill appellation. On summer mornings, fog filters in through the Chalk Hill gap where the river makes its way southwest through Alexander Valley. As afternoon temperatures rise, the fog burns off, providing for consistent mid-day sunshine. Later in the day, maritime breezes from the Pacific Ocean enter the gap, cooling down the vines in what is referred to as "Venturi Effect." The area's fog, breezes, and cool nighttime temperatures contrast the afternoon heat and allow the Chardonnay grapes time to develop complex flavors and crisp acidity.

The soils, formed during thousands of years of alluvial fan movement and flooding are composed of gravel, clay, and volcanic rock. The soil itself imparts a distinctive "mineral" quality to the fruit, one of this vineyard's signature characteristics. These complex, ancient soils, along with the area's unique climatic conditions, provide an ideal micro-climate for grape growing.

The Chardonnay is divided into five blocks on a well-drained, gravelly benchland adjacent to the Russian River. Approximately 80% of the vines are planted with budwood believed to be an old Wente clone of Chardonnay and sourced from the famed Gauer Upper Barn Vineyard. The remaining 20% is divided evenly between two other proven Chardonnay clones, 4 and 15. Collectively, these clones produce small clusters and berries.
