Everything You Need to Know to Find the Best Olive Oil

What is the first thing that pops into your mind when you think of Australia? Is it olive oil? Probably not but, after you read this, that might change.

Do you know how to tell if you are purchasing a high-quality olive oil and if it is truly extra virgin? Australia and California make it easier.I have been wanting to delve into learning more about local olive oil for some time now so when one of the pre-conference excursions for the International Food Blogger Conference was with Cobram Estate, I was eager to sign up. The Best Extra Virgin Olive Oil Comes from Australia and Cobram Estate is Australia’s number one producer.

Cobram Estate

Rob McGavin and Paul Riordan, the co-founders of Cobram Estate, planted their first olive trees in Australia in 1999. Over the years, they perfected New World production techniques to become the world’s most internationally awarded olive oil producer.

Early in 2016, they announced the launch of products made with olives from their new home in Yolo County, California, where they partner with local growers. With olive groves in both California and Australia, Cobram benefits from two harvest seasons, giving them the freshest oil naturally possible, at any time of year.

Partnering with Local Growers

Let the excursion begin! A group of 25 food bloggers eagerly boarded the excursion bus that would take us to Longview Farm in Winters, California, about 45 minutes from Sacramento. Adam Englehardt from Cobram Estate met us at the farm.

We rode on a tractor-pulled hay wagon through the olive groves to where they had an awesome spread laid out for us. Chef Kevin O’Connor was our host for happy hour. He created some delicious small bites for us using olive oil, of course.

I didn’t get a good photo of Chef Kevin so I borrowed this photo from my new friend, Imei, of My Allergy Advocate.

Once we settled in with food and drink, Adam told us about Cobram Estate and everything we ever wanted to know about olives and olive oil production. Thoughtful questions and lots of discussion made for a great learning experience.

Adam Englehardt from Cobram EstateFarmer and owner of Longview Farm, Peter Hunter, his wife Debbie and their dog Cassie, joined us. Peter is one of about 40 growers that Cobram partners with. It was so inspiring listening to him talk about how happy walking through the groves makes him feel. Nothing better than loving what you do!

Extra Virgin Olive Oil (EVOO)

The term extra virgin is used to identify the freshest, highest quality olive oil. This is obtained by harvesting the olives at the peak of their ripening process in October and November when the olives are just starting to turn color. It is cold pressed juice that is not processed and does not contain chemicals or additives.

“Extra virgin” is determined by testing for the healthful elements of total polyphenols, oleocanthal levels and most balanced fatty acid profile. Total polyphenols indicate the antioxidant level, oleocanthal is linked to anti-inflammatory properties and fatty acid balance is key to delivering the nutritional benefits.

Australia has the strictest regulations in the world about what can be called extra virgin and that’s what sets them apart from other oils.

Olive treesFake Extra Virgin Olive Oil

You may have heard about the fake or counterfeit extra virgin olive oil coming from Europe. Partly, this is a case of the media blowing things out of proportion, as usual. The stories suggest that the imported oil has been adulterated or cut with nut oils. Although recent tests by University of California showed that 7 out of 10 imported olive oils labeled extra virgin failed the international EVOO quality standards, none of the oils tested were adulterated. The US has not established a legal definition for “extra virgin” so, although mislabeling is dishonest, it is not illegal.

California vs. European Production

I bet when you think of olive oil production you see a picturesque landscape of gnarly old trees spread around rolling hills and pickers high up on ladders hand-picking the olives. Well, that is rarely the case anymore.

In Europe, much of the labor force has moved to the city. Growers who depended on those workers often have to wait until the olives ripen to the point that the stems will release when the tree is shaken or the limbs are beaten. That doesn’t happen until January or later and at that point the olives have begun to oxidize and the oil is no longer fresh. This is where a lot of the problem of “fake” oil comes in. The olives are no longer at their peak, they have lost a lot of their health benefits and don’t meet extra virgin standards.

Technology and the vineyard growing method (growing in rows) insures that olives are picked at their prime. They are pressed within hours of picking and the oil is protected from air during storage and bottling.

State of the Art Facilities at the Cobram Estate Processing Plant

After another short ride on the bus, we arrived at the Cobram processing plant in Woodside, California. We listened to a brief presentation then donned hairnets and went inside.

Putting on hair and beard netsLearning about the process was fascinating. The olives are trucked to the plant straight from the field and are moved by conveyor belt into the machinery. From there, everything is automated. They are sorted, pressed, stirred, decanted and eventually bottled.

The first machine sorts the olives. It can detect color and even small blemishes and rejects the blemished olives.

After our tour of the facility, we sampled three oils of varying age and quality.

The first two oils were very similar in color. One was just days old and quite pungent. They were both delicious and it was easy to drink the entire sample straight out of the glass. The third, an inferior quality oil, had a totally different mouth feel – like slimy oil – and very little flavor. I could only take a small sip and had to toss the rest. I read in an older news story that these inferior oils are what many consumers prefer because they are used to the old, rancid taste!!

OOCC vs. COOC

California olive growers and oil producers are working hard to make sure when you see “California” on your olive oil label, you know you can trust that it is of the highest quality.

The Olive Oil Commission of California (OOCC) was created in 2014 and is funded by California olive oil farmers who are striving to provide a better product for consumers and who wish to promote clear, simple and accurate labeling of California olive oil. The OOCC is a California government entity operating under authority provided in the California Food and Agriculture Code. California olive oil producers who process more than 5,000 gallons of olive oil during the marketing season are subject to OOCC requirements.

The California Olive Oil Council (COOC) is a trade association with the mission of encouraging the consumption of certified California extra virgin olive oil through education, outreach and communications. It was established in 1992 and is committed to upholding the highest standards within the olive oil industry through its Seal Certification Program.

This post is not suggesting that all European olive oil is inferior. There are still lots of great oils from Spain, Italy and Greece. You just need to do your research. One thing you can do is look for the North American Olive Oil Association (NAOOA) Quality Seal. Brands that participate in the program, both imported and domestic, agree to have their products randomly purchased from stores across the United States and tested to confirm they meet or exceed the International Olive Council (IOC) quality standards.

Benefits of Olive Oil

“Published research shows that no other food comes close to extra virgin olive oil for the prevention and treatment of chronic disease.” Associate Professor Mary Flynn, Brown University

  • Contains no trans-fats
  • Acts as an anti-inflammatory similar to ibuprophen
  • Contains almost 40 antioxidant chemicals
  • 70% mono-unsaturated fatty acid
  • It’s difficult to gain weight from the mono-unsaturated fats present
  • Has antimicrobial properties
  • Aids in digestion

My Takeaways

  1. My most important takeaway from the excursion is that olive oil has a shelf life of about two years unopened and a couple of months once opened. I have a tendency to buy “really good oil” and save it. I’m not sure what for and I will not be doing that anymore.
  2. If the oil is from Australia, buy it! It is the freshest it can possibly be.
  3. I love buying local so, based on what I learned during this excursion, I will definitely be buying California extra virgin olive oil in the future.
  4. Checking your label for best by date, certification labels, etc. can be helpful but are not a guarantee of great extra virgin oil.

  2. This post makes total sense to me. Places that produce great wine also make great olive oil

  3. There is huge!!! I have olive oil that is more than 2 years at home. I’m going to discard it. And when next I am buying one it wili be the ones from Australia.

  4. I never even knew olive oil was grown in Australia! How interesting. I tend to buy local produce as much as possible so probably won’t get to try it though which is disappointing!

  5. What an incredible opportunity to learn about olive oil! Authentic good quality olive oil is such a treasure. I haven’t heard of this olive oil farm, but I live in Ca. I must check it out!!! Great post.

  6. Wow this is an interesting read, I’ve always loved the really good olive oil from Europe and I never thought that it would be even better in Australia. Good to know!

  7. I had no idea how olive oil was processed! I live in Spain, we get pretty good olive oil too😍 great to know that Australia has good quality olive oil, that’s really curious☺️ Thanks for sharing your experience☺️

    • California olive oil is great, too. Producers here are using a lot of the modern techniques like Australia. They harvest at the right time and process within hours of harvest.

  8. That’s an eyeopening account of olive oil. It is a amazing the way you have differentiated the different types of olive oil and explained their benefits at the end. Does olive oil really contain 40 antioxidant chemicals?
