Our Story

Rancho Mahnaz - Creston, California

01 - THE FOUNDER

The Woman Behind The Ranch

Mahnaz Westerberg is a visionary entrepreneur, author, and steward of the land. As the founder of Rancho Mahnaz, she has transformed her private Central Valley estate into a sanctuary of beauty, intention, and craftsmanship. With roots in culture, art, and a deep reverence for the earth, Mahnaz does not just produce olive oil. She creates experiences rooted in heritage and designed to last.
02- THE LAND

18 Acres of Pure Legacy

Nestled in the Central Valley of California, Rancho Mahnaz is a single estate where every olive tree is tended by hand and every harvest is a deliberate act. The land is not a facility. It is a sanctuary. Eighteen acres of intention, where the soil, the season, and the craft converge in every bottle.
03 - THE ORIGIN

Where It All Began

She was a little girl in a warm kitchen, watching her mother cook and sing at the same time. The scent of fresh herbs, the golden shimmer of olive oil in the pan, the rhythm of her voice — it was more than food. It was a feeling of love, health, and heritage that wrapped itself around her soul. Although she lost her mother at the age of ten, that memory never left. It lives on in everything Rancho Mahnaz creates.
04- THE HISTORY

Six Thousand Years of Knowing

Long before modern medicine, ancient civilizations understood the power of the olive. Hippocrates documented over 60 medicinal uses. Persian physicians prescribed it for inflammation, digestion, and skin. Egyptian royalty used it in sacred rituals. What they knew intuitively, science has since confirmed — extra virgin olive oil is among the most studied and celebrated foods on earth. At Rancho Mahnaz, that lineage continues.
05 - THE DIFFERENCE

Not All Olive Oil Is Created Equal

Most olive oil on grocery store shelves is diluted, mislabeled, or harvested long past peak. True extra virgin olive oil — cold pressed, high-oleic, and polyphenol-rich — is a different substance entirely. It does not oxidize. It does not degrade. It retains the full nutritional profile that made olive oil a cornerstone of the Mediterranean diet for millennia. That is the only kind made at Rancho Mahnaz.
06- THE USE

From The Table to the Skin

Drizzle it over a finished dish. Press it into warm skin. Take it by the spoonful as a daily ritual. High-oleic acid, cold pressed, and rich in polyphenols — it nourishes from the outside in and the inside out. One ingredient. Infinite intention.
07 - THE FLAGSHIP

Liquid Gold Estate Select

Hand-picked on the ranch and cold-pressed within hours, Liquid Gold is blended from two extraordinary varietals — Arbequina for its silken texture, Picual for its depth and finish. Each of the 1,500 numbered bottles includes two botanical infusion concentrates and a certificate of authenticity signed by Mahnaz. True luxury is not merely owned. It is experienced and remembered.

08 - GIVING BACK

Moms Against Poverty

Moms Against Poverty was founded in 2008 by Delfarib Fanaie and a group of Iranian-American mothers in the San Francisco Bay Area. The organization operates under a specific US Treasury OFAC license and funds schools, orphanages, clinics, and food programs in Iran, Cambodia, India, Senegal, Guatemala, and beyond.

Mahnaz believes that what you produce should serve more than your table. A portion of every Liquid Gold allocation supports Moms Against Poverty — the Iranian-American founded nonprofit that has impacted over 7 million children and families across 18 countries through education, healthcare, and orphan care.

"This is my legacy — for every table, every generation, and every soul who believes that food is more than what we eat. May it bring beauty to your table and vitality to your spirit."

— MAHNAZ WESTERBERG, FOUNDER
