Olive oil taste test

How to find the best extra-virgin olive oil

(Trader Joe’s California Estate oil)

Our taste tests show that some olive oils don’t make the grade.

Many “extra-virgin” olive oils, including some big names, don’t taste good enough to merit that description. By definition, extra-virgin olive oil is supposed to be flawless, but only the top nine of the 23 products our experts tried were free of flaws.

Consumer Reports purchased 138 bottles of extra-virgin olive oil from twenty-three manufacturers. The olive oil was sourced from a variety of countries including the U.S., Argentina, Greece, Chile and Italy.

More than half tasted fermented or stale. Two even tasted a bit like . . . let’s just say a barnyard. That problem can occur if oil is stored in vats containing sediment that has begun to ferment. The good news is that two products were excellent; one of those is a Consumer Reports' Best Buy.

You may not be able to easily spot a dud. Most people don’t sip olive oil straight from a glass, as our experts did, and foods can mask imperfections. In addition, many consumers assume that olive oil should be a liquid version of the fruit they put in a salad or martini. Wrong. Superior oils are fresh and fragrant, with complex flavors of ripe and unripe fruit, grass, herbs, nuts, or butter, for starters. If you’re used to a particular product, you might not realize what you’re missing until you do your own side-by-side comparison. It’s like learning to appreciate and enjoy fine wine.

Several big name brands earn some of the lowest scores

The Consumer Reports' Ratings show that you don’t need to buy oil with an Italian heritage to experience the best.

Oils produced in California surpassed those with an Italian heritage in Consumer Reports' latest taste-tests of 23 extra-virgin varieties, which are supposed to represent the pinnacle of quality. McEvoy Ranch (grown on a 550-acre property in Petaluma) and Trader Joe's California Estate, both from California, earned the highest scores and were the only products deemed "Excellent."

Three of the six "Very Good" oils also have a California pedigree: B.R. Cohn, 365 Everyday Value (Whole Foods), and California Olive Ranch. O-Live & Co. is pressed from Chilean olives. Only Lucini Premium Select and Kirkland Signature (Costco) Select Toscano are from olives grown in Italy.

Three were designated Consumer Reports' Best Buys ─ Trader Joe's California Estate and Kirkland Signature Select Toscano (Costco) ─ both at 35 cents an ounce─and 365 Everyday Value 100% Californian Unfiltered from Whole Foods, at 38 cents an ounce. 

Well-known brands, including Bertolli, Crisco, Filippo Berio, Goya, and Mazola tasted somewhat stale and had a variety of other flaws. Botticelli and Capatriti were described as old-tasting and barnyardlike. Goya, a winner in past taste-tests, was somewhat pungent and slightly bitter this time around.

What’s extra-virgin, anyway?

In Europe, the International Olive Council, chartered by the United Nations, establishes standards and works to ensure that products labeled extra-virgin, the highest grade of oil, live up to their billing; the countries do the policing. According to the IOC, extra-virgin olive oil must meet strict chemical and organoleptic (taste and smell) standards, including low levels of acidity and ultraviolet-light absorption. (High levels suggest poor processing or deterioration.) It has been extracted from mashed fruit by mechanical means, not through the use of heat or chemicals, which can reduce flavor. It should have at least some fruitiness and be free of defects in flavor and aroma.


Consumer Reports recommends using the top-rated extra-virgin olive oils in ways that will show off their strong, complex, fresh taste ─ such as drizzling them over bread. Lesser products can be used in cooking, which can mask an unpleasant taste.

    • Trump's Russia scandal takes an unexpected turn

      On Friday afternoon, FBI Director James Comey delivered a classified, hour-long briefing to the Senate Intelligence Committee on the Russia scandal, and soon after, the Senate Intelligence Committee sent “formal requests to more than a dozen organizations, agencies and individuals, asking them to preserve all materials related to the committee’s investigation” into the controversy. We don’t know much about how the briefing went – committee members were tight-lipped following Comey’s presentation – though Sen. Marco Rubio (R-Fla.) tweeted late Friday that he’s “now very confident” that the committee will conduct “thorough bipartisan investigation” into Russia’s “interference and influence.” Reading

She was Trump's maid of honor at her 2005 Palm Beach wedding, People magazine reported at the time.

    • Vince McMahon fired The Rock before Raw went on the air

      We knew The Rock would be appearing at the Staples Center in Los Angeles, California to do something for the crowd before Monday Night Raw went on the air this evening, because he told us. And he did just that, hyping up the crowd while letting them know to stick around after the show to be a part of filming a movie he’s working on. You knew they would run an angle, though. Sure enough, after he was done doing his thing, Vince McMahon showed up to fire him (the first video cuts off right as the firing is happening, the second is right after it happened): Hopefully WWE releases a better video later. We’ll pass it along if they do.

      It’s only T minus 25 days until we get to watch Emma Watson dazzle us on the big screen as Belle in Disney’s new adaptation of Beauty and the Beast. We’ve already gotten sneak peeks of how the actress looks wearing that iconic yellow dress and—allegedly—her rose-covered fairy tale wedding gown, and while we’re admittedly obsessed with the epic costume design in the film, we’re equally excited about the prospect of seeing Watson’s personal style throughout the movie’s press tour. Given the fact that she’s been a muse for major designers and is regularly at the top of best-dressed lists for awards shows and other red carpet events, we know she’s going to serve us some seriously good looks. That said, we’re keeping track of all Emma’s fashions leading up to the film’s release on March 17th, so check back often to see her latest looks as well as what designers she’s wearing.
