At our southern-most ranch we grow seventy acres of Chardonnay, Sauvignon Blanc and Merlot in relatively equal proportions. Proximity to the San Pablo Bay brings cooling fog and climatic moderation to this vineyard. The predominate soils type is silty clay loam which acts more like clay during the winter months, however changes to a silt that feels like walking on the moon during vineyard sampling at harvest. Both white grape varietals produce wines with tropical aromas and flavors, perfectly complimenting the Markham style. The estate was recently replanted with a higher vine per acre density which promotes intensity within the terroir of the property.

Historically, this 120-acre parcel in the Oak Knoll AVA was a blackberry ranch located in the middle of the valley floor. Deep, versatile soils allowed Markham Vineyards to plant an assortment of varietals to compliment both our portfolio and capitalize on the potential of the ranch. Sauvignon Blanc is planted along the riparian corridor which helps repel pests and grows well in the deepest soils. Both the Chardonnay and Merlot utilized budwood from other estate vineyards. Our love for Yountville Merlot flavors made it an easy choice here as well. Small "tasting room only" bottlings of Pinot Noir and Muscat are also grown on the property.

This 60-acre ranch is situated at the base of Mt. St. Helena, at the headwaters of the Napa River. Rocky soils and lack of water stress the Cabernet Sauvignon and Petit Verdot plantings, producing low yields and intense blackberry jam characteristics. The surrounding hills create a small canyon that is full of bay laurel and wildlife, including grape loving bears (sometimes influencing vineyard operations and harvest sampling). Thermal inversions typical to the area allow extra hang time to our nine different Cabernet clonal selections and two Petit Verdot clonal selections. Since the 1970s, this ranch has had a history of producing amazing Bordeaux varietals for Markham Vineyards and continues to impress. 

At the southern end of the Rutherford bench in the heart of Napa Valley, a total of 100 acres are planted of Merlot, Cabernet Sauvignon, Cabernet Franc, and new plantings of Malbec. Originally planted over 140 years ago, wines from these vines have always achieved accolades. Ancient volcanic action created alluvial fans below the well-drained clay loam and Coombs gravelly loam soils. White, chalky soils are most evident on the western slopes of the property. In combination with the bay controlled fog intrusion zone of Yountville, this ranch has proven an ideal terroir backdrop for the cherry/sour cherry characteristics present in these wines. Merlot clonal selections hail from the ‘Three Palms’ ranch in Napa Valley, whereas our Cabernet Franc came over from Bordeaux in a suitcase! Most recent replantings focus on new Cabernet clones, tighter spacing and ultimately switching row direction.

With 350 acres of vineyard strategically located in several of Napa Valley’s best growing regions, Markham Vineyards selects grapes from several microclimates to achieve balanced and rich wines. Knowledge and experience are combined with Mother Nature to produce grapes for Markham’s award winning wines. Our ranches allow us to focus on ‘estate’ designate wines here in our tasting room, while additionally creating consistent blends each and every vintage.
