Winemaker Notes
The Hypothesis Oakville Cabernet Sauvignon is produced from one of best vineyards in all of the Napa Valley (The Money Road Vineyard in Oakville). This Cabernet is small in production and spends 18 months in French Oak barrels. The blend is primarily Oakville Cabernet Sauvignon, but also has Pritchard Hill Malbec and Pritchard Hill Merlot. The wine has incredible depth and complexity, delicious black fruits and amazing opulence. Hypothesis Oakville Cabernet Sauvignon is a muscular wine that loves to be paired with food, but is sophisticated enough to stand on its own.
Blend: 94% Cabernet Sauvignon, 3% Malbec, 3% Petit Verdot

Wine Enthusiast
Assertive cedar and toasted oak aromas give way to rich, dark chocolate and blackberry flavors in this well-structured, appropriately tannic wine. Good concentration and balance keep it appetizing despite its full body. Best 2025–2032.
Roots Run Deep Winery began in 2005 when founder Mark Albrecht set out to answer a simple question: could great Napa Valley wine be both exceptional and accessible? After decades in the wine retail business, Mark saw that too many great bottles were priced or positioned out of reach for everyday drinkers—so he sold his house and everything in it to fund the winery's first vintage and prove otherwise. There was no inherited estate or outside investors behind the project; friends and family who believed in the vision helped turn that leap into a working winery.
That first wine, Educated Guess Napa County Cabernet Sauvignon, became the foundation of the brand. Roots Run Deep believes great wine lives at the intersection of science and craft—combining vineyard data, chemistry, and instinct with a bit of educated guesswork to create wines that are thoughtful, expressive, and approachable. The idea worked: over the years Educated Guess has earned Best Buy, Best of Class honors, and is consistently one of the top selling Napa Valley Cabernets under $50.
More than twenty years later, that same philosophy shapes everything the winery makes. Roots Run Deep still sources fruit primarily from Napa Valley vineyards, while also working with exceptional growers in Sonoma and other regions across California—and the portfolio has grown beyond that first bottle to include a range of small-production wines defined by site, style, and discovery. The name reflects what has always mattered here: strong foundations, deep vineyard relationships, and the belief that great wine should feel both special and approachable.
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.
Home to some of the most sought-after Cabernet Sauvignon in America, Napa Valley’s Oakville district stretches across the center of Napa's valley floor and foothills between the Vaca and Mayacamas Mountains. This AVA is home to the legendary To Kalon Vineyard and Martha's Vineyard, as well as many powerhouse wineries including Screaming Eagle, Silver Oak, Robert Mondavi, Opus One, Far Niente and Groth.
The climate is generally warm and agreeable, resulting in year after year of favorable vintages. Summer days see a gentle tug of war between warmer inland air and the cool air coming in from the San Pablo Bay, creating an ideal environment to grow red varieties. Oakville's diverse soils, namely ancient sea bedrock, clay and gravel, are well-drained, and perfect for high-caliber viticulture.
Cabernet here is often bottled varietally but is also popular in Bordeaux Blends. Oakville wines are known for their silky, sensual textures, structured tannins, dark and brooding fruit and lovely aromatics. These age-worthy and prestigious wines are favored by collectors throughout the world.
