    The Cliffs Vineyard

    Horse Heaven Hills, AVA

    Perched high on basalt bluffs above the Columbia River, The Cliffs vineyard takes its name from the dramatic dark rock formations that define the landscape. These ancient volcanic remnants and sandy loam soils naturally stress the vines, resulting in smaller berries and concentrated flavor.

    Warm, sunny days in Horse Heaven Hills are balanced by persistent winds that cool the vineyard each evening, preserving acidity and allowing the grapes to ripen with power and elegance.

    Beverly Vineyard

    Beverly, WA AVA

    Set on a steep slope above the Columbia River in the newly established Beverly AVA, this rugged estate site sits among old-growth sagebrush in one of the warmest, driest areas of the Columbia Valley. Hot days, steady winds, and sandy loam soils—formed by the ancient Missoula Floods—create naturally stressed vines and small, concentrated berries.

    These conditions are ideal for heat-loving Rhône varieties, producing bold, powerful wines with depth and intensity.

    Zillah Vineyard

    Rattlesnake Hills, AVA

    Stonemark Vineyard is a cool growing site in the Rattlesnake Hills AVA. This vineyard is recognized as one of the classic sites for stunning Washington wines. It is conventionally farmed with no cover crops. Average yields are 5 tons to 7 tons per acre. Stonemark is rocky, rugged ground overlooking the western end of the Yakima Valley that delivers lean, structured, cool-site reds.

    Soaring Eagle Vineyard

    Wahluke Slope, AVA

    Located in the heart of the Wahluke Slope AVA, Soaring Eagle Vineyard benefits from one of Washington’s warmest and most consistent growing regions. The site’s long sun exposure, low rainfall, and sandy, well-draining soils encourage balanced vine growth and concentrated fruit development.

    Cool evenings help preserve freshness and structure, creating depth and complexity while allowing the vineyard to fully express the bold, layered character that defines the Wahluke Slope.

    Four Feathers Vineyard

    Columbia Valley, AVA

    Located within the expansive Columbia Valley AVA, Four Feathers Vineyard is one of the region’s deeply rooted and historically established vineyard sites. Positioned alongside the renowned Cold Creek Vineyard, the site benefits from a warm climate, abundant sunlight, and arid growing conditions that are ideal for consistent ripening and concentrated fruit development.

    The vineyard’s well-draining soils and low annual rainfall allow for precise vineyard management and balanced vine growth throughout the season.

Winemaking That Reflects the Vineyard

Our oak program is designed to complement rather than overpower the wine. French and American oak barrels, alongside neutral oak, contribute structure and elegance while allowing vineyard character to remain at the forefront. Through techniques like sur lie aging and extended maturation, we create wines that are polished, balanced, and deeply connected to the land they come from.

We use a thoughtful combination of stainless steel, concrete, and oak aging, with each vessel playing a distinct role in expressing the wine’s personality. Stainless steel preserves freshness, purity, and vibrant aromatics, while oak contributes structure, depth, and layered complexity.

Concrete plays a particularly important role in our winemaking approach. Unlike stainless steel, concrete is porous, allowing a gentle exchange of oxygen that softens texture and builds complexity without imparting flavor. Concrete eggs and upright tanks also create natural convection currents during aging, continuously moving the wine and lees without mechanical stirring. This process enhances texture, minerality, and mouthfeel while maintaining freshness and precision.

Our winemaking philosophy begins with the vineyard. Every decision in the cellar is guided by one goal: to preserve and elevate the character of Washington’s diverse terroir — from windswept slopes and volcanic soils to the balance shaped by warm days and coo
