In addition to producing wines under our own label, Mike Smith is also the winemaker for several other quality producers in the Napa Valley.

Carter Cellars’ winemaking begins with the best grapes from world-renowned vineyard sources. The cultivation of these grapes is an arduous process which includes limiting vine yields, beneficial trellising techniques, integrating pest management in the vineyard and harvesting completely by hand. All of this ensures that the grapes we use are optimal for creating our limited production, high quality wines.

The winemaking consists of as little intervention as possible, limiting the addition of sulfur and refining the wine through gravity. The wines are allowed to mature and fully integrate with the new oak creating a product that is true to its varietal character and sense of place while having the structure and complexity to age and give pleasure for many years.


Quivet Cellars produces very limited quantities of handcrafted boutique Napa Valley Cabernet Sauvignon and Syrah, by selecting specific rows of fruit from Spring Mountain, Kenefick Ranch and Las Madres Vineyard. The premium fruit is uniquely crushed, aged in rare French Oak and masterfully blended by winemaker Mike Smith into the wines of Quivet Cellars.

The Cabernet Sauvignon and Syrah, resulting from this process, are outstanding in flavor, fragrance, and body. These unique wines are available to those who are part of the Quivet family in limited releases.

MCG Cellars is a family passion. From the vine to the table everyone involved with the MCG brand shares their passion for making the best ultra-premium estate wine possible. The vision is to create wine that is elegant in structure and balance and consistent in quality vintage after vintage. The guiding principle is that making ultra-premium estate wine has always been an art driven by passion – yet they have never forgotten that wine is meant, quite simply, to be enjoyed!

Scarlett Cabernet Sauvignon, named after the founder’s great granddaughter, is crafted exclusively from fruit grown on our 64-acre Rutherford Estate. Scarlett, the inaugural offering by MCG Cellars, holds a special place in the hearts of the family as the driving force behind the brand.


Ancillary Cellars is a new collaboration between celebrated Napa valley vintners Mike Smith and Mark Carter.  The driving force behind Ancillary Cellars is a desire to explore cool climate varietals crafted in a uniquely californian style by showcasing the cool climate subtlety of the Sonoma coast ava.  we have tried to craft a wine that evokes the layers, complexity and delicacy of pinot noir.


Matt and Amber Denny’s goal was simple, find the best fruit they could personally put their hands on, find the best winemaker in the business, and be involved in every step of the process. Becklyn Cellars wines are hand crafted from start to finish. We source our grapes from the prestigious Rutherford and St Helena Districts in Napa Valley. The wines are aged in new French oak and carefully bottled with the utmost care to preserve their unique balance and complexity.
