Duncan Peak Vineyards has been farming organically since 2014. We work closely with organic specialists to enable our farming to promote a living, breathing ecosystem.


CCOF Certified Organic

At Duncan Peak, we have exclusively farmed organically since 2014. In 2019, Duncan Peak Vineyard successfully became a Certificated Organic Vineyard after the transition period.

Our farming practices consider the whole ecosystem and its animals. We farm responsibly to reduce greenhouse gas. And we use natural compost to feed our vines and use cover cropping to keep the soil healthy.

Working closely with organic specialists enables our farming to promote a living, breathing ecosystem. We strive to create a balanced and healthy environment. For example, Duncan Peak maintains various flowering plants along the vineyard border to provide habitats for beneficial insects that protect our vines and encourage pollination by visiting pollinators.

Estate grown, From soil to bottle

Our firm belief is that our wine’s exceptional quality starts from the ground up. Rich clay loam soil is one of the greatest assets at Duncan Peak Vineyards. We choose to make our wine from estate-grown grapes because we trust the quality of our land, our water, and our efforts.

Quality is key to our brand, so we are involved in every step of the farming and winemaking process. But, of course, it helps that enjoy every moment of it.

Our commitment to producing the highest quality wines is exemplified by our time in the vineyard and the cellar. But more so, we are committed to our land, caring for it, nurturing it, and developing a deep relationship with the plants and creatures that call it home.

A Foundation of Old Vines

The oldest vine we planted was in 1987 and continues producing grapes today. The deep roots system supports the vines’ water and nutrients needs. As a result, the vines have dense, concentrated tastes and inky red color.

The wines of Duncan Peak carry the rich and complex flavors of these aged vines. Because old vines produce fewer clusters than young vines, these vintages grow more exclusive with each passing year – and for a good reason. As the vigor of the old vine declines every year, the quality of the fruit becomes better year after year. This rich aroma and flavorful taste are part of what makes our wines extraordinary.

Sheep grazing & wildlife-friendly

Every April, dozens of sheep come into the vineyard and help us to eliminate weeds. Sheep grazing is a sustainable way of farming, reducing carbon emissions and energy use while giving the animals healthy grazing land to enjoy in the spring.

But our connection with the wildlife of Duncan Peak goes deeper than natural farming methods. We strive to find balance and harmony with our surrounding wildlife. As a result, you can find different animals on the property throughout the year, from wild turkeys and deer to majestic cranes resting in our pond. They are no strangers to us, nor are we to them. We are especially fond of our hummingbird friends, who spread pollen from plant to plant – you’ll see many nectar feeders on our property for these beautiful creatures. Duncan Peak is proud to provide a sanctuary for these animals and thankful for their continued presence on our land.

Built on Natural water irrigation

There are two water sources on the Duncan Peak property. Our reservoir collects rainfall in the winter and spring to use for vine irrigation. The reservoir helps reduce our impact on the aquifer and save water. In addition, gravity diverts the water to the field, reducing our vineyard’s energy use.

The second water source is spring-fed. The spring waters flow gently through the land, watering the cover plants of our vineyards and providing drinking water for the wild animals that are our neighbors. While we have access to well water, we avoid it due to its high boron content that can alter the taste of our wines.
