Roots Run Deep

Napa Valley Malbec and Bordeaux varietals rated by Wine Enthusiast and Wine Advocate.

Roots Run Deep produces wines from Napa Valley, the North Coast region of California renowned for structured Cabernet Sauvignon and rich Bordeaux varietals. The winery's portfolio centers on The Ph.D. Malbec, a wine that has earned recognition from Wine Enthusiast and Wine Advocate, alongside The Ph.D. Merlot and the Educated Guess Reserve Cabernet Sauvignon. Malbec, traditionally associated with Argentina's Mendoza region, takes on distinctive character in Napa's warm days and cool nights—developing deep color and ripe dark fruit while retaining acidity. The Merlot and Cabernet Sauvignon reflect the valley's capacity for elegant, age-worthy reds. These wines have been assessed by prestige critics, with The Ph.D. Malbec and Merlot receiving particular attention in critical evaluation.
