Winemaker Notes
Starting with only a handful of purchased grapes in 1978, Marietta Cellars has been a standout winery in Sonoma and Mendocino since the very beginning. Founded by Chris Bilbro, a Sonoma County native with winemaking roots dating back three generations, Marietta rose to prominence with its revolutionary Old Vine Red, a California red blend that essentially created the category. The winery has slowly expanded its estate holdings over the past thirty years, evolving into a beacon for high quality, balanced Cabernet Sauvignon, Zinfandel, and Rhône variety blends. Now fully estate-based and organically farmed, Marietta has vineyards spanning 310 acres in the Alexander Valley, McDowell Valley, and Yorkville Highlands. Notable among their heritage plantings are California’s oldest Syrah blocks, planted in the late 1800s.
Scot Bilbro, Chris’s son, has brought Marietta into its next, incredibly exciting phase. After graduating from UC Davis with a degree in Viticulture and Enology in 2007, Scot joined the winery full-time, assuming the role of winemaker in 2012. Steeped in the history of the California wine country and the traditions established by his father, Scot combines his creativity and technical background in guiding the winery’s vision of viticulture and winemaking. Today, the fusion of traditional values and style with modern precision have culminated in the most highly regarded wines of Marietta’s four decade history.
A noble variety bestowed with both power and concentration, Cabernet Sauvignon enjoys success all over the globe, its best examples showing potential to age beautifully for decades. Cabernet Sauvignon flourishes in Bordeaux's Medoc where it is often blended with Merlot and smaller amounts of some combination of Cabernet Franc, Malbecand Petit Verdot. In the Napa Valley, ‘Cab’ is responsible for some of the world’s most prestigious, age-worthy and sought-after “cult” wines. Somm Secret—DNA profiling in 1997 revealed that Cabernet Sauvignon was born from a spontaneous crossing of Cabernet Franc and Sauvignon Blanc in 17th century southwest France.
Nearly a northern extension of Napa Valley, Alexander Valley starts just north of the small, Knights Valley, and is just a few minutes drive from the Napa town of Calistoga. It is Sonoma County’s hottest AVA. But the Russian River, which runs through the valley, creates cooler pockets and its soft, alluvial soil is ideal for grape growing, especially Cabernet Sauvignon. In fact, some believe that Alexander Valley Cabernets truly rival the best from Napa Valley and many of the heavy-hitter producers have largely invested here.
In addition to Cabernet Sauvignon, which makes up over 50% of plantings, Merlot and old vine Zinfandel thrive here. Ample, fleshy Chardonnay and Sauvignon Blanc dominate white wine production. Some old-vine plantings of Grenache have also been discovered and more recent experiments with Sangiovese and Barbera show great promise.
