FRESHNESS CAPTURED

Marciano Estate’s Napa Valley olive oil is certified organic, estate-grown, hand-harvested, and milled on-site in St. Helena to preserve its fresh, peppery flavor and natural polyphenols. As I searched for an ideal site to grow and make wine, I also wanted a property where I could finally bring my longtime dream of producing olive oil to life. Today, Marciano Estate is home to beautiful olive groves with hundreds of trees, featuring both Italian and Spanish cultivars.

Each fall, our olives are hand-harvested into small, vented bins and brought immediately to our on-site mill, where the oil is expertly extracted just moments after picking, helping our St. Helena olive oil retain its fresh, spicy flavor, high polyphenol content, and antioxidant properties.

Our certified organic, 100% extra virgin Marciano Estate olive oils are bottled to retain their vibrant, pungent, spicy character. They’ve been honored with multiple gold medals from the California Olive Oil Council, the Napa Valley Olive Oil Competition, and were named Best EVOO of the USA in 2023 by the EVOOWR.

Caring for the land is at the heart of everything we do when producing our Napa Valley organic olive oil. After milling, we compost all of our olive pomace on-site, returning valuable nutrients to the soil. Our vineyards and groves are never left bare, carefully chosen cover crops enrich the earth, improve soil structure, and support a healthy ecosystem. Each spring, we also graze sheep through the property, a natural approach that nurtures the land, enhances soil fertility, and encourages the long-term health of our trees.

“When I was a young boy in Marseille I walked to school, and the aroma from the small olive oil factory on that street was always in the air. It is the scent and the flavor that I grew up with.”
