Mulvane wines are single-vineyard wines, which means they only come from one vineyard. We source from some of the finest vineyards in Napa Valley and Santa Barbara County in order to craft our premium wines. Good winemaking starts with the vineyard, hand-selecting the fruit and letting the winemaker create the magic. The wines capture the soul of the vineyard and the artistry of those who craft the wine. 

Since no two vineyards are the same, nor is a vineyard the same within itself, we pay meticulous attention to terroir, letting each unique location direct our winemaking. Quality, not quantity, is our concern.

Cabernet Sauvignon

For Cabernet Sauvignon there is no place like Napa Valley. Flanked by the Mayacamas and Vaca Mountains and stretching from San Pablo Bay to Calistoga, the climate is varied depending on location.

At Mulvane we focus on three regions – the mid-southern area of Combsville which allows us to create wines that are structured and elegant, the mid-valley of Rutherford, and the upper valley of St. Helena where we produce a richer and more opulent wine.

St. Helena Cabernet Sauvignon

Sourced from Neal 3 Vineyards which lies where two mountains ranges - the Mayacamas to the west and Vaca to the east – funnel together to create a pinch in the valley. The constricting mountains  cause a sort of a thermal dynamic. As the northern region of Napa Valley warms, it creates an inversion that draws cooler bay air up from the south. The larger air mass gets pinched by the constricting mountains, and eddies at the narrow crossing where the Neal 3 Vineyard is planted. In turn, the back-flowing air creates a cooling breeze that tempers the late afternoon heat.

Neal 3 is planted to the “See” clone – an older clone of unknown origin that creates deep, structured wines. The rocky/gravelly soils are extremely well draining and produce small berries on very small clusters. This results in deeply colored wines with sturdy tannic structures.

Rutherford Cabernet Sauvignon

Since the 1800s, Rutherford has produced some of the world’s greatest Cabernet Sauvignons. Set in the afternoon shadows of the Mayacamas Mountains and sandwiched between Oakville and St. Helena, Rutherford is widely regarded as the sweet spot for Cabernet Sauvignon in Napa Valley. The Rutherford Bench Vineyard was planted in 1989 to the well-regarded clone 7. The wines from this benchland site consistently deliver saturated berry-like flavors, silky tannins and an intriguing aromatic element often referred to as “Rutherford Dust". Rutherford Bench has received Organic Certification from the CCOF (California Certified Organic Farmers).

Coombsville Cabernet Sauvignon

The mid-southern valley has developed a well-deserved reputation for growing cooler climate Cabernet Sauvignon. Lambert Family Vineyard, situated in southern Napa’s Coombsville/Tulocay area is our source. This 12 acre vineyard sits on shallow, rocky-gravel soils and is solely focused on growing cooler climate Cabernet Sauvignon.

The microclimate, influenced by the cooling breezes and fog off San Pablo Bay, help grapes assert the classic Cabernet acid/tannin profile. Reverence Vineyard was planted to a variety of clones primarily on the 110R rootstock in 2002. 

Cabernet Franc

One of the largest, most beautiful and highly acclaimed vineyards we source from, Stagecoach Vineyard climbs 900 and 1700 feet up the southern face of Pritchard Hill to Atlas Peak. The site is planted to a wide range of varietals and rootstocks and features several distinct microclimates.  Our Cabernet Franc block is from the Pritchard Hill region of in-the most-sought-after section of Cab Franc - Block 1.  This section is lower-yielding than most of the vineyard. 


Santa Barbara was a latecomer to the vinous landscape of California, yet this terroir has earned kudos for producing some of the best Burgundian and Rhone-style wines in the country. As one of California’s only east-west running valleys, the region enjoys mild temperatures, very little rainfall and a long, long growing season.  

Santa Barbara County Syrah

At Mulvane we wanted to craft a wine as an homage to Rhone-style wine . This lead us to Santa Barbara County and White Hawk Vineyard. The vineyard sits on a southern facing slope (don’t forget this is an east-west valley!) of Cat Canyon some 21 miles from the Pacific and 2 miles north of the tiny town of Los Alamos.

The marine influence causes cool, early morning fogs that envelop the site before giving way to bright sun. It’s planted at an elevation of 900 feet on pure sands that immediately drain off water and nutrients forcing the vines to work extra-hard to survive. White Hawk is custom-farmed using sustainable and primarily organic viticulture methods. The yields here are miniscule and the berries intense.
