I go through a lot of olive oil. I buy it at Costco. The one I buy is harvest dated and from Italy. They get it every year and they have it till the inventory is gone. A chef friend recommended it. https://www.costco.com/Kirkland-Signature-Toscano-Extra-Virgin-Olive-Oil%2C-1-L.product.100335985.htmlThere are some years where he doesn’t like it as much.
I also will buy the California Olive Ranch oil when they have it at Costco. It is also my go to brand if I’m out of olive oil from Costco and need to buy it at the grocery store.
The other oil I use is avocado oil. That I also usually buy at Costco.
