Is my Kirkland olive oil real?

I know this has been a big topic for a while. I read about it and then sort of shelved the idea that my extra virgin olive oil is probably fake. I just recently met a nutritionist (brief chance encounter) and she explained to me how seed oils are made. While I don't remember the details it sounded not so great. Then she told me she was reading this book called "Extra Virginity" which broke down the olive oil industry which basically isn't governed at all.

So now i'm off to find "real" olive oil. I think she said Kirkland Organic in a glass bottle. is there such a thing? I only found the organic in a plastic bottle so bought the one in glass. Now, i'm searching the internet and thinking my regular olive oil isn't real. Does anyone have a list of real olive oils? I can't seem to find one. Thanks.

  1. Yes, the Kirkland Tuscan Organic is good extra virgin olive oil. The fact is, Italy does NOT export it's Nuvo 'premium' extra virgin olive oils, as there is not enough available for the local population. Italy does export good, usually blended, extra virgin olive oils which is what's available for export to us. Do what I do, go to Italy and bring it back for your personal use or find a reputable source on the internet.

      well, i don't have the luxury of going to Italy but I was hoping a trip to Costco or somewhere slightly closer and more affordable. I can't quite leave a note to my family- "dear guys, i'm off to italy to buy some olive oil. be back in a few weeks!"

      1. re: trolley

        The Kirkland glass bottle oil is in a tall, narrow, square-ish bottle. It's dated by year of pressing and when they're out, they're out. It's a great value.

        1. re: ferret

          i got this one but i'm suspecting it's not real.

          1. re: trolley

            It's real olive oil and it's very good (and a good value).

          2. re: ferret

            Can you still get the Tuscan version at Costco? The last time I checked it had been replaced by a Spanish oil.

            1. re: Bigjim68

              It usually appears every winter, following the autumn harvest and processing. It will be gone later in the year. I haven't checked this month to see what came in, but even if Spanish the QPR will be there.

              1. re: Bigjim68

                If it's the Arbequina, buy it all! It's delicious and I can only occasionally get any. The Tuscan is very good and quite a bargain, too.

                1. re: mcf

                  It is the Arbequina. It came packed in two packs, and was about the same price/pack as the Tuscan/bottle.

                  1. re: Bigjim68

                    It's m favorite and while Tuscan is great and in my store year round, the Arbequina rarely is. So delicious.

                  2. re: mcf

                    Can't agree on the Kirkland Spanish Arbequina -- we found it bitter, with very little flavor. We much prefer the California Olive Ranch Arbequina -- no bitterness, and a great fruity flavor. Twice the price, but well worth it in our view (available at Wrong Hole Foods).

              2. re: trolley

                Just trying to give you the true perspective on Olive Oils from Italy. The Kirkland Tuscan is a good grade extra virgin olive oil, a great value and it tastes very good. Also, try looking on-line for other possibilities, the hunt may be rewarding.

                1. re: treb

                  IMO 'real' OO is only available where it's grown. Even dealing directly with the OO grower/manufacturer you can not be 100% positive you are getting the real thing.
                  How does one explain a OO grower with X number of trees capable of producing X number of gallons of 'extra virgin' OO being able to sell twice that much in one season? Happens all the time folks. European food investigators have long since discovered that many OO growers are adding other oils right at the farm before shipping.
                  The myth that there is such a product as authentic extra virgin OO available in Costco is just that.
                  The 'good stuff' is always only available to those who are willing to pay premium price.......for anything. Us peons are lucky to get whatever scraps are left.
                  When you're paying about $180.00 a litre for Lambda OO you know you're getting the real deal. Pay $16.00 a gallon for something with an Italian looking label at a big box store and you ain't.

                  1. re: Puffin3

                    Great explanation Puffin, most are blended and indeed we get the 'scraps', although good scraps!

                    1. re: treb

                      This is absolutely wrong. I can name dozens of estate bottled, often single varietal, extra virgins, many with DOP certification of authenticity, from Italy, Spain, France, Portugal, and Greece available at a number of retailers, form Fairway to Eataly to to Greek markets in Queens. Many are, by design and tradition, blends of varietals. Sure, there's tons of junk, tons of fraud, and tons of mediocre but still useful and real evoo, but it's just absurd to deny that in the US, we have greater access to more kinds of delicious, authentic extra virgins than the average resident of Spain or Greece, whose local supply, while most certainly "real", will likely be all he or she can get. You need to know what to look for, and it's not that mysterious.

                    2. re: Puffin3

                      one can dream, right? I did read about the test that UC Davis conducted and wanted to find the results of that test. Well, i'd like to start buying this oil again.


                      I used to buy it at the farmers market in San Francisco Ferry building but then I moved away and things fell apart. I think it's a decent one.

                    3. re: trolley

                      C'mon up north to the Sonoma/Napa/Orland area: there are local producers making olive oils. Jacuzzi near the town of Sonoma has a big tasting room, and IIRC there's at least one shop on the square selling locally-produced olive oils. It's a much shorter trip!

                        sure. but i live in colorado so it's strictly mail order. that's fine. i just want to know if there are good ones. i'm willing to let go of my kirkland.

                        1. re: trolley

                          There are good ones, depending on your budget. If you have a good budget look into EVOO's from Italy as well. BTW - Kirkland is a good EVOO and great value, don't throw out the baby with the bath water.

                          1. re: treb

                            the baby is still here. I looked up my olive oil and it was harvested and made in Italy so I feel better. I'm open to more local stuff like CA. I'm planning on mail ordering Bariyani as soon as I work thru this bottle.

                            1. re: trolley

                              Last time i was in napa (a few years ago now) the wonderful market in st helena had a huge variety of local olive oils. I bought-and LOVED- this one:

                              The napa valley naturals (organic) line also has some great olive oils and are more reasonably priced- also widely distributed, so check stores near you as well.

                              And i also lovelovelove their fig basalmic vinegar

                          2. re: trolley

                            Real does not mean you will like it. For example, many olive oils have a peppery finish that can be off-putting. The biggest question will be from what kinds of olives. That is much more important than any other factor. It's a waste of money to spend a lot on an olive oil you've never tasted.

                            Do you have any favorite restaurants near you that use olive oil? Ask them what they use.

                        2. re: trolley

                          Greece has very nice olive oil too. Italy isn't the only source.

                          1. re: rasputina

                            As does Spain but, Italy produces, IMO, the best.

                        3. re: treb

                          I think the most important thing you can do is to taste a number of very high-quality olive oils, regardless of price. Then you'll have a true baseline for quality, other than whether something is perceived as "real" or not.

                          I use Kirkland extra virgin oil. It's fine, but I use it for cooking when I don't need very high heat. I don't use it for salads or when I want to highlight the taste of the oil.

                          1. re: treb

                            How do you know that Italy doesn't export any olio nuovo? I know for sure they do at least in small quantities. The problem is that it is ready in October/November and due to customs regulations and shipping it never gets here until February of the following year. Hence it's not really "nuovo" anymore.

                            We do bring a lot of oil back from Italy because we go regularly to see family, but it isn't enough.

                            We also love olio nuovo from Trader Joe's, which comes in winter (it's in stock now, in Boston) and stays for a short time. Apologies that I don't have the exact title of what they call it. It has a very green color and a white label written in script. It costs $14.00 for 1000mL. We buy several and use that supply throughout the year.

                            1. re: treb

                              I get a bottle or two of olio nouvo every year before Xmas from Olio2go:


                            2. The question could be "Do you like it?" I find that some of the more expensive EVOOs are wasted on my palate.

                              1. I believe that California Olive ranch brand was tested and came out as real (100%) OO.
                                I just threw out a Kirkland brand, I thought it tasted gross. I might have got a bad batch.
                                I have had a TJ brand that I thought tasted good, but don't know if it has other oils blended in. I think it was called TJ Tuscan EVOO.

                                            trolley, the California Olive Ranch brand is a available at most supermarkets. It makes a nice, fairly inexpensive, day-to-day oil. They have an Arbequina oil which is what I prefer to buy, but even their regular oil is decent.

                                      2. hmmm... "Real" olive oil versus what? That has me a bit puzzled. I'm also curious why the olive oil must be Italian? There are many truly great premium olive oils in the world. I love trying the olive oils of different countries, as well as different regions within a country. Greece is a favorite, but having visited several of the more famous groves there has undoubtedly prejudiced me just a little bit. Some truly delicious olive oils come from Morocco, Turkey, California, well many countries produce excellent olive oils. But there is only one reliable guide for great olive oils, and that is your personal taste and preferences. It could be fun to give the rest of the world a chance... '-)

                                            Buy from an estate or producer, not a packager. Buy a bottle that has a DOP or similar seal of origin and authenticity. Buy a bottle that indicates a real place, like a village or region, not a warehouse. Buy a bottle that can tell you about the oil inside--its qualities, varieties, location. Buy a bottle with a harvest and use by date. Taste, and taste again--that's the pleasure--and find what a fresh, sound oil feels like, and find one whose flavors you like.

                                            1. re: trolley

                                              Sorry. I appear to have wrongly assumed you were knowledgeable about olive oil. Soooo... Basically what Bob said. If you want the good stuff,you have to buy the good stuff. I'm not a Costco shopper, but in the world of commerce "Kirkland" is the Costco house brand. That pretty much equates it with Walmart's "Great Value" brand in groceries, "Sam's" in sodas, and "Equate" in OTC drugs or "Trader Joe's" house brands. Going with the "Trader Joe's" labels as an example, if someone wants top quality premium wine, "Two Buck Chuck" ain't gonna cut it.

                                              There is a TON of information available to you via the web about olive oil, as well as lots of information about what "organic" REALLY means when it comes to their (plants) and our (animals) feed. If you educate yourself on the subject of how olives are pressed onto oil and how it is graded after pressing, as well as what "organic" really means, you'll be able to make your own informed decisions which is always more reliable than depending on others for information.

                                              Colavita is an extremely reliable brand of "Italian extra virgin olive oil." I've used it for years. As is Minerva's new "Village" (χωριό) brand extra virgin olive. I used Minerva when I lived in Greece, and still do when I can find it. Excellent.

                                                Sorry, but with all due respect, you're mistaken about your characterization of Kirkland as a cheap low-quality alternative. Yes, it's a private label re-badging as a house brand, but unlike the other examples you mention, it is frequently of equal or higher quality than national or more-famous designer brands.

                                                Nothing could be more inappropriate than comparing Kirkland anything to Two-Buck Chuck or the Wal-Mart brands. A better comparison would be to the 365 Brand found at WF, which frequently comes out tops in tests.

                                                  1. re: acgold7

                                                    To clarify: by good I did not mean expensive. Oils like the Minerva Horio, the Kirkland Toscano or a Spanish picual evoo from Jaen or a well-balanced everyday oil from a respected Pugliese grower both for about $10/ltr, both current harvests, at the World Market housewares-food-wine chain. There are others like them that can offer sound, reliable, mostly traceable flavors, and can be excellent values. Thee are others. There are also expensive oils that are not worth it at all, sometimes because they are way too old or are just overpriced, overblown boutique packages. I think the first step is learning to identify genuine extra virgins of soundness and quality--and how they match their price points--and then to taste until you find a taste you like. Just because it's the real thing, doesn't mean you'll like it, regardless of price--there's that much variety in taste, texture, and production.

A few years ago we did a tasting at a famous small boutique producer in Tuscany, who proudly brought out his latest and greatest vintage for us, and it was so bitter and peppery it had the entire large group of us Americans in tears.

                                                      We managed to swallow it but I'm sure he thought we were all uncouth, uncivilized savages. He was probably right.

                                                        1. re: mcf

                                                          Fairway bottles an excellent Gata Hurdes DOP, which comes from Estremadura in SW Spain. It's got a nice balance of peppery kick and smooth fruit.

                                                        My point -- and this is a personal viewpoint based on my own personal experience -- is that when I want a premium brand, I shop for a premium brand. As I said, I am not a Costco member, but whether I want Minerva Greek olive oil or Colavita Italian olive oil or Chateau Lafitte Rothschild wine, THOSE are the brands I shop for, NOT a store (ANY store) brand.

                                                          Colavita is one of the dilutred, fraudulent brands.

                                                          Costco has seriously strong quality control.

                                                          You'd do better to actually know what you're buying and recommending.

                                                          1. re: mcf

                                                            Colavita may have failed the UC Davis standards test for extra virgin, but it's still olive oil. "Extra virgin" has been a loosely used term, which, thankfully, is now increasingly better regulated and enforced throughout the world. Here's an industry publication report on Colavita: make of it what you will.

                                                            1. re: mcf

                                                              Thanks for this link but as I stated the UC Davis link is no longer active but I think this other thread summarized what I needed to know. I didn't get the Costco Organic but regular. It looks like my oil can be traced back by this Toscano IGP label. So it looks like it's "real". As I mentioned, I don't care if my oil is from Tunisia as long as it's real olive oil as opposed to a seed oil mix. Taste is secondary as well.

                                                              1. re: mcf

                                                                LOL! And who is defining "fraudulent"? Here's a link to the "new" American standardized version of thee AOC's definitions.

                                                                Here is a link to the quantity package of the standard Colavita extra virgin olive oil I've been using for years and years:

                                                                For a while now, Colavita has also been offering "Mediterranean" olive oil, which is a blend of premium quality extra virgin olive oils from Italy, Spain, Greece, and Portugal. This is the blend that many less scrupulous companies market as "Italian" olive oil simply bcause they BOTTLE it in Italy. A blend is not that uncommon, nor is it illegal, but MANY American's do not understand all that much about olive oil becase as a GENERAL rule of thumb, we don't "grow up" with it.

                                                                The Colavita website is fun to explore. My own PERSONAL suspicion is that the only reason they ever introduced the EVOO BLEND of olive oils is because they signed a contract with Rachel Ray to provide her with an EVOO label... That is a personal co9njecture, and I've never read anything that stated that, but based on long usage of Colavita's olive oils (My son used to be the owner of the Colavita elite amateur development cycling team, which meant wheneve the team raced in Dallas, this mom got to host the team and Colavita is VERY generous with its host gifts from its cycling team(s) (don't even know if that's still plural, the 2005 crash did such damage to sponsorship on a world level!). Anyway, Coavita is NOT a bad guy in the olive oil owrld.

                                                                Knowing more about olive oil and learning how to read labels is very very very important! Marketing and PR firms ALWAYS put a weird spin on so very many things that the consumer is on his/her own when it comes to educating ourselves so we are "spin proof." For example, anyone up for a bottle of "gluten free" extra virgin olive oil? "Nuff said...!!!!! '-


                                                                Here are some links to Colavita's website where you can learn a lot about their products:

                                                                1. re: Caroline1

                                                                  I don't need to learn *more* about Colavita. It used to be my brand til I found better oils for less money..

                                                              2. re: Caroline1

                                                                And as others have noted, Kirkland should not be put in the same category as other store brands, and a little research would have shown that. Prejudice is an ugly thing.

                                                                1. re: Caroline1

                                                                  I am sorry but I'd trust and buy Kirkland brand olive oil over Colavita. Not all store brands are created equal and people don't pay membership just to buy 'store brand' olive oil. I buy Kirkland Toscano olive oil which I think is one of the best olive oil you can buy for the money. It is a single origin from Tuscany, Italy and has the exact month and year of harvest printed on each bottle. The flavor and the color are both amazing.

                                                              3. re: Caroline1

                                                                FYI, Trolley is concerned from the findings from the UC Davis investigation of many olive oils available in the US. Colavita was found to be one of the brands that "failed to meet the extra virgin olive oil standards, according to this study"


                                                                1. re: E Eto

                                                                  well, that's exactly what I was going to mention. That Colavita was one that failed and was passing off their oil as "real" when in fact it was probably a mixture of cheaper seed oils. They use the minimum amount of real olive oil and write things like "imported BY Italy". None of the report results are available on the UC Davis website. In fact, now it looks like they're selling their own oil.

                                                                2. re: Caroline1

                                                                  You mention Colavita; are you sure it is 100% Italian, let alone Tuscan?
                                                                  I have tasted Kirkland against Colavita, and there is only one I would put in a salad or dipping saucer.

                                                                  1. re: jayt90

                                                                    For the record,the Davis study tested oils for acidity, sensory quality, and other qualities that are associated with the term "extra virgin". Levels of acidity--or rancidity--is a baseline marker for this kind of oil, as is method of production. Colavita, like other oils, "failed" on the numbers, and on sensory defects but was not accused of passing off seed or other oils as olive oil. It never claims, also, that's Tuscan; its plant in the region of Molise uses southern olives, most likely from nearby Puglia, Italy's largest growing region, as well as its own area. I'm not a great fan of the brand, and never buy it, but have no reason to believe it's anything other than oil from olives. There have been, and are brans, that have committed these frauds, of course, as Tom Mueller has so vividly detailed. The Kirkland Toscano is IGP controlled--that is, certified as having been made from olives grown in Tuscany and made according to national and EU standards. (There are producers whose hq is indeed in Tuscany but whose oil is made from less expensive oils or olives trucked up from Puglia, Calabria, and Sicily--Tuscany produces less than 5% of the Italian crop.) Again, this designation does nothing to ensure personal pleasure, but does make it a "real' (and representative) extra virgin oil. It is, indeed, a good value. As for "premium" oils: that term's always only a personal one, and while I use value extra virgins for everyday cooking, I, too, also shop for and use smaller-production and more characterful , and, yes, expensive, oils for finishing and seasoning. Like I drink an everyday red wine most everyday, and a special red on, well, special days. But that can change, too, depending on a lot of things.

                                                                    1. re: bob96

                                                                      Yay, bob96! This whole thread is most interesting because I've been all over the UCDavis Olive Center website looking for their "report." i could find none. So I googled newspaper and magazine reports of the report. Ahah! They said I could find the report in question in .pdf format here:

                                                                      As you will see if you click the link. either the "report" has been removed *OR* it never existed in the first place. I highly suspect that if there ever was such a report, it may have been removed because of gross misunderstanding and/or oversimplification. I can readily understand how such thing might happen. Anyone remember "mitochondrial Eve" and the gross misinterpretation of that scientific finding by the media?

                                                                      I suspect that what has happened is that a variety of formal olive oil tastings from several formal tasting/grading sessionss and a number of lab analysis reports could be mistakenly interpreted by media to lead to the false conclusion that some classic true and pure single source/single "vintage" evoo's might not be ranked "at the top of their game" simply because EVERY crop, from grapes and olives to flowers grown for the perfume industry and tomatoes grown for the table have "vintage" years. You just don't hear about them all that much in association with foods other than wine and/or olive oil, but they do exist for all plants, and are important. And olive oil, like the grapes grown for wine, has "varietals" as well as flavor and quality that is affected by weather and the soil the trees are grown in (terroir). I would have to see a UCDavis report first hand that states Colavita or any other premium brand of single source or mixed (for flavor balance) botlings of Italian, Spanish, Poruguese, and Greek evoo's is contaminated with oils from anything but olives.

                                                                      But if anyone would like more information about their particular olive oil purchase, here's the place to get it:

                                                                      1. re: Caroline1

                                                                        Your brand tested inferior and Kirkland was one of the few that met the highest standards.

                                                                        1. re: Caroline1

                                                                          I'd like to point out that the report is now almost five years old. Also, it's produced by the Olive Center at UC Davis... it is in their interest to imply California olive oils are better. That said, I do buy olive oil from California and other parts of the US (Georgia and Florida). One I like to use for an "everyday" oil is the California Olive Ranch Arbequina. For a more expensive oil, I often buy one from Georgia that is a blend of Arbequina olives from both Georgia and California.

                                                                          1. re: MelMM

                                                                    2. re: Caroline1

Unlike store brand labels at Sam's, TJ's Walmart etc. The Kirkland label is always 'better' in quality and price than most brand name products. As for the Tuscan Olive Oil at Costco, let's keep it in perspective a tad, at 16.00/liter it's good olive oil and a good value. It's not exceptional by any means but, better than most other store label EVOO's.

                                                                      1. re: Caroline1

                                                                        1. re: Caroline1

Read up on how Italians keep the good stuff for themselves and Americans get Olive Oil that is punched, due to an inept and corrupt FDA, the US is the dumping ground for everything Europe does not want due to strict regulations and inspection. So your Colavita EVOO is one of the Olive Oils that failed the test.

                                                                          1. re: europagirl

It's just that you shouldn't expect mass-marketed oils to be of the highest quality, regardless of whether they're labeled "extra virgin" or not.

                                                                      2. re: Caroline1

                                                                        1. re: GH1618

Spanish producers also find it more profitable to ship their excess (and there's lots of it) to Italy for blending by Italian or multinational companies, and then re-packaged and sold abroad in "imported from Italy" brands. The multinational sources are so labeled on the bottles. The Italian address brings them more than if they'd exported it out as Spanish olive oil.

                                                                        2. re: Caroline1

I don't understand why so many people think that EVOO has to come from Italy. There are a lot of countries, including the USA, that produce real extra virgin olive oil at decent prices. California Olive Ranch sells in many stores and online. Also some of the smaller Greek oils are very good. You have to buy the Greek olive oils online. A good site to try real EVOO is Bariani is another great brand that sells online and they are made with olives grown in California. Bariani is a small family owned operation.

                                                                        3. Not sure where this comes from but it is one of the disorganized drawers in my crowded brain.

                                                                          Put the oil in a glass container in the refrigerator. The more it congeals the better the quantity of extra virgin it is.

                                                                          I do not know if you can "unblend" by pouring off the liquid fraction.
