How To Taste Olive Oil

Posted by Hannah Broaddus

Olive oil has a specific way that it should be tasted to get the full effect of the oil -- just like you would taste wine. I do a lot of olive oil tastings in meetings with customers, along with training our staff internally.

Here's a quick run down if you've never officially been taught how to taste olive oil.


First, Use The Right Tasting Glass

The official choice of International Olive Council tasters (or anyone judging olive oil) is small, tulip-shaped blue glasses.




This is because the blue glass hides the color of the oil inside, allowing you to do truly blind tastings. The goal is to avoid any visual biases you may have. For example, if you see a very green olive oil, your brain may associate the color green with good oil, and affect your unbiased judging abilities.

Everyone in the olive oil industry agrees -- color doesn't mean anything when it comes to olive oil. Light colored Extra Virgin Olive Oils can have the most pungent flavors, and a dark green oil can still be very mild or of poor quality. They're two totally unrelated traits.

If you're just doing an informal tasting, we understand if you decide to skip the blue glasses -- just try not to judge the oil based off the color.


Warm Up The Oil

A key part of releasing the aroma and flavor of the oil into the air is to warm it up.

Pour about 1-2 tablespoons of oil into your glass. Then cup one hand under (which will heat the oil from below using the warmth of your hand) and one hand over (to capture any smells inside the glass).

Swirl it around a few times to release the smells into the air trapped inside your cupped hands.



Bring the glass to your nose, remove your hand and smell the oil deeply. Take note of the aromas you're sensing. Look for adjectives like green, ripe, earthy, fruity, or nutty. Or perhaps, you'll be able to smell some of the exact flavors in the infographic below. Take note of them before you begin tasting.

Smelling the oil, just like you would with wine, is part of what allows you to fully taste it in the next step.


Slurp / Strippagio

Take a small sip of your olive oil (about 1/2 to 1 teaspoon is plenty, don't overdo it). Coat the inside of your mouth and let the flavors cover your tongue by relaxing your mouth. Allow it to sit in your mouth for a moment to fully coat.

Next, suck in some air. Touch your tongue to the back of your top teeth and inhale. I like pretend that I have straws in my mouth like walrus teeth, and that I'm using them to suck in air. Other folks sharply inhale air through their teeth, which sprays the oil that has just coated your tongue around your mouth, and allows air to enter your throat which brings out more of the flavor.

This method of sucking in air through your teeth for tasting olive oil is called strippagio, and everyone has their own flair.

Close your mouth with the oil still inside and breath out. As the air moves through the olive oil in your mouth, it picks up aromas and brings them up behind the back of your mouth, into your nasal passages.

Usually before swallowing, I do this process a few times -- breathing in using strippagio, trying to note any flavors, and breathing out with my mouth closed.



Lastly, you will want to swallow some of the oil to get the full flavor notes. Some flavors are only tasted on the back of the tongue, so this is where you will taste some of the pungency of the oil.

If you are tasting a peppery oil, it's common in this stage that the oil will make you involuntarily cough -- some growers say that if it doesn't make you cough, it's not truly good oil! That's not really true, however, it all just comes down to personal preference on flavor.


Note The Flavors You Taste

Lastly, make notes of the flavors that you smell and taste throughout this process. Look for adjectives like the following:


Apple/Green Apple: indicative of certain olive varietals

Almond: nutty (fresh not oxidized)

Artichoke: green flavor

Astringent: puckering sensation in mouth created by tannins; often associated with bitter, robust oils

Banana: ripe and unripe banana fruit

Bitter: considered a positive attribute because it is indicative of fresh olive fruit

Buttery: creamy, smooth sensation on palate

Eucalyptus: aroma of specific olive varietals

Floral: perfume/aroma of flowers

Forest: fresh aroma reminiscent of forest floor, NOT dirty

Fresh: good aroma, fruity, not oxidized

Fruity: refers to the aroma of fresh olive fruit, which is perceived through the nostrils and retro-nasally when the oil is in one’s mouth.

Grass: the aroma of fresh-cut (mowed) grass

Green/Greenly: aroma/flavor of unripe olives

Green Tea: characteristic of some unripe olive varieties

Harmonious: balance among the oil’s characteristics with none overpowering the others

Hay/Straw: dried grass flavor

Herbaceous: unripe olive fruit reminiscent of fresh green herbs

Melon: indicative of certain olive varietals

Mint: indicative of certain olive varietals

Pear: indicative of certain olive varietals

Peach: indicative of certain olive varietals

Peppery: stinging sensation in the throat which can force a cough (see pungent)

Pungent: stinging sensation in the throat which can force a cough (see peppery)

Ripely: aroma/flavor of ripe olive fruit

Round/Rotund: a balanced, mouth-filling sensation of harmonious flavors

Spice: aroma/flavor of seasonings such as cinnamon, allspice (but not herbs or pepper)

Sweet: characteristic of mild oils

Tomato/Tomato Leaf: indicative of certain olive varietals

Tropical: indicative of ripe olive fruit with nuances of melon, mango, and coconut

Walnut/Walnut Shell: nutty (fresh not oxidized)

Wheatgrass: strong flavor of some green olive fruit

Woody: indicative of olive varietals with large pits
