O Olive Oil & Vinegar

About Us

Our story

On a sunny, California day in 1995, O's Founder did something totally original. He crushed fresh citrus with Arbequina olives and created a new twist on California olive oil. His opus – O Meyer Lemon Olive Oil – was the first of its kind and launched the O Olive Oil & Vinegar signature line of artisan crushed olive oils.


Our success with artisan olive oils soon led us to the crafting of wholly unique vinegars using locally-sourced wine and traditional fermentation methods. Our premium vinegars and olive oils give chefs and home cooks endless options to bring the fresh flavors of California to the table.


Our olive varietals are crushed hours after being harvested from our partner family farms. This makes our olive oil the freshest available and full of beneficial polyphenols and antioxidant richness. We pioneered crushing real, clean ingredients, such as seasonal citrus and fresh herbs, together with California olives. It’s more work and expense, but totally worth it! The clean and fresh flavors are authentic and unmatched by other products.


Our vinegars are handcrafted in small batches at our state-of-the-art fermentation facility in the heart of California wine country. We always start with the cleanest, best-tasting ingredients and processes. Then, our very own vinegar cultures and time-honored techniques allow nature and time to work their magic.
