Extra-virgin olive oil (EVOO) is free from chemical treatments, has a rich flavor, and boasts a low level of oleic acid, which is a marker that it’s made from healthy olives.

However, numerous brands resort to clever marketing to mask mediocre olive oils as premium. This is where Costco’s Kirkland Signature olive oils come in.

Costco’s EVOO is certified by Bureau Veritas, a renowned agency for testing and certifying products, ensuring the oil meets all the requirements to be classified as extra-virgin.

A key standard for EVOO, per the USDA, is that it must possess “excellent flavor and odor.” This means that despite Costco’s affordable pricing, its oil doesn’t skimp on quality.

So when you see a bottle of Kirkland Signature extra-virgin olive oil, you can simply grab it while being totally at ease, knowing that what you're getting is 100% the real deal.
