Our Story
Support Alpha Delta Phi
Cor Unum Napa Valley’s mission is to deliver world-class wines, celebrate Alpha Delta Phi’s rich history and brotherhood, support educational programming for undergraduate brothers, and most importantly, enhance the Alpha Delta Phi lifelong experience beyond our college years.
With every bottle purchased, 20% of the proceeds are donated to the 1832 Foundation, which supports the educational programs that empower undergraduate student leaders of Alpha Delta Phi. Your contribution helps fund impactful leadership initiatives that prepare our members for success both in college and beyond.
Our Approach
Honoring the Land
Great winemaking starts in the vineyard. We harmonize with Napa Valley's diverse terroir to craft wines that capture its essence. Our sustainable approach uses minimal organic inputs and regenerative practices, nurturing a vibrant ecosystem—from soil microbes to local wildlife.
Sourced from varied vineyards with sedimentary, volcanic, clay, and loam soils, our blends feature heritage California selections and premium European clones for rich, dynamic flavors in every bottle.
A Commitment to Balance
Our winemaking philosophy is all about balance — between soil and rootstocks, fruit and canopy, structure and acidity. We hand-harvest grapes at peak ripeness, then meticulously sort them by hand and with advanced optical technology to select only the very best fruit.
The result is wines with pure fruit expression, elegant complexity, and beautiful depth. Bold reds that reveal themselves with decanting. Vibrant whites that shine with freshness and texture. Every bottle honors both tradition and innovation.
Sustainability at Our Core
Preserving the environment behind our wines has been central to our philosophy. As a charter member of the Napa Green Winery program since 2007, we were among the first three Napa Valley wineries to earn certification.
Our commitment spans every operation:
Napa Green Certified Facility: We meet over 120 sustainability standards, from water conservation to cutting our carbon footprint. Regenerative Farming: We nurture a vibrant vineyard ecosystem, safeguarding biodiversity—from soil earthworms to roaming jackrabbits and foxes. Next-Generation Solar-Powered: Our winemaking facility runs entirely on a massive solar array.
