On a recent visit I noticed a smaller, and new-to-me, bottle of Kirkland olive oil sourced directly from California. It's so good that it quickly earned a permanent spot on my Costco shopping list.

Costco’s Kirkland Signature private brand is one of the strongest draws to the mega warehouse chain, on par with the big name brands.

Although olive oils from different countries will taste different, California's climate ... less than 0.3% (the main reason why Costco's extra virgin olive oil is a big deal).
