“The 2023 Spring Mountain Cabernet Sauvignon is a stunning wine, showcasing a gorgeous blend of ripe blackberry, black plum, and dark cherry aromas accented by hints of graphite, cocoa, violet petals, and wild herbs. It immediately impresses with its depth and structure, bold yet polished, delivering a full-bodied mouthfeel framed by fine, well-integrated tannins. Layers of dark/red fruit, mineral nuances, and gentle spice develop gracefully across the palate, creating a sense of harmony and balance. The finish lingers with clarity and lift, suggesting significant aging potential. Already compelling, this vintage is a brilliant wine that promises even greater complexity with time.”

Pritchard Hill is distinguished for producing robust, densely structured, and complex Cabernet Sauvignons. Since the 1980s, Greg Melanson has been cultivating Cabernet Sauvignon on Pritchard Hill. Flint Knoll sources its fruit exclusively from a single southeast-facing vineyard block situated on a steep, rocky slope, where the vines experience significant stress due to limited water and nutrient availability. This challenging terroir provides an optimal environment for the production of world-class Cabernet. The vines are planted at elevations ranging from 1,100 to 1,350 feet above sea level, in Sobrante loam and clay loam laden with volcanic rock.
Our 2021 Melanson Vineyard Marquess Cabernet Sauvignon exudes a beautifully complex bouquet of crème de cassis, ripe blue fruits, cacao powder, tobacco and graphite.

Perched at the summit of Howell Mountain, Ciminelli Vineyard is the home of Impensata. The south and east-facing slopes and porous, volcanic soils are ideal vineyard real estate. Planted under the watchful eye of David Abreu, 15 pristine acres of Cabernet Sauvignon, Cabernet Franc, Merlot, Petit Verdot, and Sauvignon Blanc are now flourishing amongst 25 acres of thoughtfully manicured forest.
Situated at high elevation above the valley floor, Howell Mountain is defined by its thin, rocky, and nutrient-poor volcanic soils.

Varietal: Merlot
AVA: Spring Mountain & Oak Knoll
Vineyards: Keenan Mailbox & Shifflett Ranch
Region: Napa Valley
Our Spring Mountain Merlot comes from Keenan’s Mailbox Vineyard. Planted to 11 acres of Merlot in rocky soils, this mountainside vineyard produces some of the finest Merlot in Napa Valley. Sited above the dense layer of fog that creeps up the Napa Valley most evenings, the vineyard warms earlier in the morning and temperatures remain warm throughout the night. The combination of these warm temperatures , steep hillside vine rows, and gravelly soils promotes stress on the vines, leading to increased intensity of flavors and aromas in the finished wine.
Shifflett Ranch is nestled against the Mayacamas Mountains just south of Yountville. Regarded as the southernmost true alluvial fan of the Mayacamas Range, the volcanic soils and rocky hillside aspects are ideally suited for Bordeaux varietal grape growing.
Made in a Right Bank Bordeaux style, Philippe & Maayan blend varietals and vineyards to create a symphonic compilation of aromas and flavors. Our Spring Mountain Merlot gives this wine its rich, powerful flavor, while our Spring Mountain Cabernet Sauvignon provides structure and a layered complexity. Our Oak Knoll Merlot lends the velvety texture and profound elegance inspired by the wines of Pomerol and Saint-Émilion. This wine is deep purple-hued, with a rich nose of dark blue fruits, black currants, cassis, crushed violets, leafy herbs, and warm baking spice. It is a full-bodied Merlot with a stacked, concentrated mid-palate, lush mouthfeel, and a ripping, powerful finish.
Our take on an exquisite Bordeaux blanc-style Sauvignon Blanc from the Rutherford Bench in Napa Valley. The unique gravelly loam and volcanic-based soils give this wine a distinct schist-like texture and pronounced minerality. Barrel-fermented and aged for 17 months; it is creamy, complex, and captivating. It has beautiful aromas of honeysuckle, zesty citrus, pineapple, vanilla, and subtle herbal undertones. This carries to a medium-bodied white wine with an elegant, layered mouthfeel, vibrant acidity, and remarkable depth.

The 2023 growing season was very long, cool, and even featuring healthy yields and no heat spikes, and the wines show this in their freshness, purity, and elegance. The winter was one of the coldest on record, and the Spring started cool and wet, with heavy rains saturating the soil. Bud break didn’t occur until mid/late April, about two
weeks behind average. Cool and even temperatures contributed to a terrific and heavy fruit set. Verasion began at the end of July and did not finish until the third week of August, about three weeks behind average. October and November brought warmer
temperatures and harvest went smoothly under idyllic conditions until mid-November. Our 2023 wines show remarkable purity and finesse along with depth, concentration, and perfectly polished tannins.
