Kirkland Signature California Extra Virgin Olive Oil is a premium, 100% California-grown extra virgin olive oil presented in a 1-liter (33.8 oz) green glass bottle.

It is first cold-pressed with a maximum acidity of 0.3%, meeting strict extra virgin quality standards.

The oil delivers a well-rounded flavor profile that is fruity and robust with a characteristic peppery finish — ideal for dressings, dipping, sautéing, and finishing dishes. It is Kosher certified and a Product of the USA, making it one of the few large-format domestic extra virgin olive oils available at Costco.
