I read an article Food Renegade posted on this yesterday. In the Food Renegade piece, one test to see if your olive oil is extra-virgin is to put it in the refrigerator and see if it turns solid or cloudy. I have Kirkland branded Organic Extra Virgin Olive Oil (which I use often). I put it in the frige last night and it hasn't turned cloudy at all - I mean not one bit. Kirkland Organic is listed here as a brand found to be accurately labeled as Extra-Virgin, however, so I'm wondering if the frige test is a good test, or if maybe Kirkland gets its EVOO from multiple suppliers, some true, some not -?
