Our Howell Mountain Vineyards
Discover the Howell Mountain vineyards behind Howell at the Moon Wine, where mountain-grown grapes become handcrafted Napa Valley wines.
Our Vineyards
Exceptional wines begin long before the grapes are harvested. At Howell at the Moon Wine, every vintage starts in the vineyard, where the unique climate, elevation, and volcanic soils of Howell Mountain create ideal conditions for producing premium Napa Valley wines.
Since 2001, our commitment has remained the same—to cultivate exceptional fruit that reflects the character of the land while honoring the traditions of mountain viticulture. Rather than focusing on large-scale production, we emphasize quality, allowing every bottle to express the individuality of each growing season.
Whether you're enjoying a private wine tasting or ordering from our online shop, every wine begins with the remarkable vineyards that make Howell Mountain one of California's most respected wine-growing regions.
Lillian’s Vineyard
In 2001, prior to planting my initial vineyard, Dr. Daniel Roberts, aka, Dr. Dirt was employed to analyze my volcanic soils and to design a 3.5-acre vineyard to complement the Howell Mountain terroir that was to be planted. Several weeks of analysis and research, including my climbing into the large soil test pits that were dug in order for me to have a better understanding why wines from this terroir could be so unique and special, resulted in a decision to plant rootstock 3309, with Bordeaux clone 337.
The feeling was that these combinations might soften the highly tannic wines produced in this appellation creating more balance without compromising the complexity and concentration of the grapes. The remaining 1.5 acres were planted in 2004 after years of attempting and finally receiving timber harvest, and erosion control permits from the appropriate state and county commissions. This vineyard was named to honor the memory of my mother, Lillian Cohen, who instilled the knowledge to work as hard as you can at whatever goals you may want to achieve, and then hope you're a little lucky.
The Knoll Vineyard
As a result of Dr. Roberts earlier soil analysis, a second 3-acre vineyard was planted as well in 2004 on a knoll resting 100 ft. above the farmhouse and initial plantings. Even though this vineyard is on the same property, the soils proved to be very different, being deeper and richer, enabling us to plant rootstock 112 with clone 4.
We feel this combination will deepen the potential of this already vigorous young vineyard and complement earlier vineyard development. Cover crops include rose clover, crimson clover, and Blando brome, which complement the vines already planted, and remain consistent with our belief in sustainable farming.
The Beauty of Howell Mountain
Located above the Napa Valley floor, Howell Mountain is recognized worldwide for producing Cabernet Sauvignon with exceptional depth, balance, and longevity.
Unlike valley-floor vineyards, Howell Mountain benefits from:
- Higher elevations
- Volcanic, well-drained soils
- Warm, sunny afternoons
- Cooler nighttime temperatures
- Long growing seasons
These natural conditions allow grapes to ripen gradually, developing concentrated flavors while maintaining the acidity and structure that define premium mountain-grown wines.
The result is fruit capable of producing elegant wines with complexity, refined tannins, and excellent aging potential.
A Vineyard-First Philosophy
At Howell at the Moon Wine, the vineyard guides every decision.
Healthy vines produce exceptional fruit, which is why careful attention is given throughout every stage of the growing season. Vineyard practices focus on encouraging balanced vine growth while allowing each block to express its natural characteristics.
Instead of rushing the harvest, grapes are picked only when they have reached optimal ripeness. This patient approach helps preserve the balance of fruit, acidity, and tannin that distinguishes our handcrafted wines.
Every vintage reflects the unique weather conditions of that year, making each release a genuine expression of the vineyard.
Healthy vines begin with careful cultivation throughout the growing season.
Vineyard Care
From Vine to Bottle
Creating premium wine is a year-round commitment that extends well beyond harvest.
Winter Dormancy
During the winter months, vines rest while careful pruning prepares them for healthy growth in the coming season.
Spring Growth
As new shoots emerge, vineyard crews monitor vine development to encourage balanced canopies and healthy fruit production.
Summer Care
Throughout the warm Napa Valley summer, the vineyards receive ongoing attention to promote even ripening and protect fruit quality.
Harvest
Harvest is one of the most anticipated times of the year. Grapes are picked when they achieve the ideal balance of sugar, acidity, and flavor, ensuring every vintage begins with exceptional fruit.
Respecting the Land
Great wine depends on healthy vineyards, and maintaining those vineyards requires respect for the land.
Every growing season presents unique conditions, making careful observation and thoughtful vineyard practices essential. By working in harmony with nature, Howell at the Moon Wine preserves the integrity of its vineyard sites while producing wines that authentically represent Howell Mountain.
This commitment to stewardship helps ensure that future vintages continue to reflect the beauty and character of one of Napa Valley's most celebrated wine regions.
