Choosing the Best Extra Virgin Olive Oil

How can I find the best quality extra virgin olive oil?
Choosing the Best Quality Olive Oil -- pouring olive oil into a bowl
Although extra virgin olive oil may improve heart health and have other benefits (partly due to their polyphenol content), there have been reports that some products are "fake" or adulterated with other types of oils. Fortunately, there are certain things you can look for on labels which help indicate a high quality oil, including seals from organizations which test olive oils for authenticity. While authenticity is very important, it is also useful to compare products in terms polyphenols (for potential "healthfulness"), which are not typically not included on labels or part of certification testing. purchased and tested 10 popular extra virgin olive oils, and tested their quality in the laboratory as well as subjecting them to sensory analysis (taste testing) by an expert olive oil tester. The results, which include CL's Top Picks, are found in the Extra Virgin Olive Oils Review.

I don't see any recent testing of olive oils. you stated tests were going to be conducted on January, 2016. It's now a few days from January, 2017. Please update your customers!!   December 26, 2016
Hi Idelle - The results of our olive oil testing will be published in early 2017. Be sure to check your newsletter, which will let you know when they are published.   January 8, 2017

The Life Extension Foundation has just released their California Estate Extra Virgin Olive Oil, which they claim has 600 mg/kg of polyphenols. This is about triple the amount in most of the others that have been tested. It would be great if you could test it.

Art Quaife, Ph.D.

JARKKO17042   August 6, 2018
LifeExtension >600mg/kg polyphenols sounds nice, but there are even better ones.

* Ecolibor, Spain. >2000mg/kg polyphenols
* Drop of Life, Greece. >1000mg/kg polyphenols

And there are some other similar products with at least 1000mg/kg at the time of bottling.

Certainly LifeExtension is better than 99.5% of extra virgin olive oils, I am sure! So much low-quality olive oil in the market.   August 6, 2018
Be aware that these products would be expected to be very bitter relative to most other olive oils, and may not be palatable for some uses -- like eating bread soaked in olive oil.

JARKKO17062   August 9, 2018
Life Extension has improved the product. It used to contain >600mg/kg. I have not tasted the old or new product.
"Our olive oil provides over 800 mg/kg of naturally occurring olive polyphenols".
"Best if used within 24 months from harvest date".

I have no idea what happens to polyphenols after for example 6, 12, 18 or 24 months of storage. Might depend on storage temperature.

Please test California Olive Ranch, their " For Everyday " not only their " Special Reserve" as I can find this at my local supermarkets and even Walmart.

I would like to know what Consumer Lab finds. I live nearly 2 hours from the closest Trader Joe's but stock up on the Greek Kalamata, my favorite, whenever I can, and I am sure many of your readers may have easy access to this store.

Test Veronica Foods Olive Oils (sold at many independent Olive Oil & Balsamic Vinegar boutiques in North America, and yes, I work at one such store) They belong to a program of UP Certification, and list harvest dates, country of origin as well as full analysis of polyphenol counts, Oliec Acid, etc. Their oils should pass all tests.

dave8314   January 10, 2016
i always buy my olive oil in 3 liter cans. is there any difference? but i would think with no light getting in,that would prolong its shelf life and its integrity.

Mark8313   January 10, 2016
Please test California Olive Ranch Extra Virgin Olive Oil. A friend of mine who survived pancreatic cancer, regularly goes to a cancer support group at Piedmont Hospital in Atlanta, GA.

Hard to believe that Costco brand EVOO (organic and regular) was not tested since they are one of the largest single source of volume sales.   January 11, 2016
Hi Robert - The Kirkland Organic mentioned in the answer is a Costco brand; we've now noted this above to be more clear.

Art8306   January 10, 2016
Please test California Olive Ranch Extra Virgin Olive Oil

Please test a couple of the Veronica Food EVOOs. Stores that sell their oils and vinegars are popping up everywhere - their own website says they supply over 700 such stores. I received 3 bottles of oil from their stores as gifts over the holidays, and gave a couple as well. The medium-sized city where I live has at least two stores sourced by Veronica. Thanks.

just wondering if anyone saw the 60 minutes segment on olive oil?

David8330   January 11, 2016
we watched the original segment + the follow-up

Robert8299   January 10, 2016
Please endeavor to test widely available store branded EVOOs, e.g., more of those from Whole Foods, Traders Joe's (several varieties),and yes, Costco. But also look for and test the direct import brands found in your larger Greek, Middle Eastern or other Mediterraneans specialty grocery stores. Some EVOO brands I've seen include Greek Diamond, Iliada, Kalamata, Liohori, Lucini, San Giuliano, Sultan, Ybarra and Zoe, -just to mention a few. I look forward to your testing results!

Ann8642   April 19, 2016
Yes, please do include Zoe, which got favorable mention in the food section of the New York Times a while ago. Would like to know if the quality is as before; it comes in cans which I agree with one of the comments here, seems as though would shield the oil from degradation by light.

Harold8298   January 10, 2016
Please test the Columela brand of extra virgin olive oil (from Spain).

Reade8297   January 10, 2016

David8291   January 10, 2016
We've been buying California Olive Ranch Extra Virgin Olive Oil, for some time. It appears to be of good quality and, HUZZA!, it comes from the good old USA. I'd love to know what you think of it. BTW - it is bottled in dark glass.

Colette 8289   January 10, 2016
Please test LUCERO olive oils, I use them all the time.

jared8288   January 10, 2016
I buy at this place and they list their polyphenols and it is way above what you tested.

Their Sierra Organic
[Certified Extra Virgin and Certified Organic | Free Fatty Acid: 0.15% |
668 mg/Kg polyphenols + 304 mg/Kg tocopherols = 972 mg/Kg total antioxidants]

Mistral Organic
[Certified Extra Virgin and Certified Organic | Free Fatty Acid: 0.20% |
592 mg/Kg polyphenols + 245 mg/Kg tocopherols = 837 mg/Kg total antioxidants]

joanna8287   January 10, 2016

Richard8331   January 11, 2016
Maybe you already know this, but the Kirkland Organic was the only one out of the fourteen imported olive oil brands UC tested where all three samples passed. I don't know if I'm supposed to include links here, but you can see this at . I do not have a financial interest in the product (in fact, I can't even buy it because I'm not a Costco member).

Louisa 8382   January 20, 2016
I hope you will evaluate the packaging material - glass vs. plastic. The kirkland brands I have seen are all in plastic bottles - not my first choice for products I purchase.   January 21, 2016
Thank you for your suggestion Louisa. You may be interested in the link provided under the section "Choose an oil that includes a harvest date and is packaged in dark glass" in the answer above. It provides a comparison of glass, plastic, and other types of packaging for olive oil.
