Kosterina is the healthiest extra virgin olive oil you’ll ever taste

Early harvest

We harvest our olives early, resulting in a high concentration of polyphenols, incredibly healthy antioxidants found in olives. To be deemed “extra virgin” you must have 55mg/kg of polyphenols - Our olive oil has anywhere from 400mg-600mg/kg at time of harvest!

100% Greek

Authentic Greek extra virgin olive oil made from a mono-varietal of certified organic Koroneiki olives grown in the Peloponnese region of southern Greece. 

100% Delicious

Harvesting our olives early not only maximizes the health benefits, but also adds a delicious smooth flavor not found in alternatives. This natural taste elevates the taste of any dish and makes it a joy to cook with.

”Not all olive oils are created equal—Kosterina is my favorite brand of olive oil. This is a product I use and that I love.”

Daphne Oz

“I love the round, buttery smoothness of Kosterina extra-virgin olive oil. It has just the right hint of green, vibrant freshness without ever turning bitter—and a super-dose of polyphenols”

Robin Berzin, MD

“I use Kosterina’s EVOO constantly. One of my favorite snacks to make for myself or the kids is a sliced ripe avocado, seasoned with lemon or lime, a little salt, and a drizzle of Kosterina’s EVOO.”


What is the smoke point of Kosterina Everyday EVOO?

The smoke point of all Kosterina extra virgin olive oils is over 425° F, making it an excellent choice for grilling, roasting, baking, frying, or cooking at most high temperatures. You can read more on the science of cooking with olive oil here.

What is the flavor profile of Kosterina Everyday EVOO?

High-quality EVOO should smell like fresh grass, fruit, or vegetables and reveal more fruit and vegetable flavors as you swirl it around your mouth and taste it. Kosterina Extra Virgin Olive Oil, made from Koroneiki olives, has notes of green tomato, artichoke, and banana. As a high polyphenol EVOO, when sipping or tasting it, you will experience a strong peppery sensation at the back of your throat when you swallow it (which might cause you to cough! a tell-tale sign of strong antioxidants).

How should olive oil be stored?

In a cool, dry place away from direct sunlight and never in the fridge. We recommend displaying your beautiful, opened Kosterina bottles on the countertops in your kitchen - and your sealed back ups in the pantry!

How are Kosterina polyphenol counts measured?

Kosterina has a chemical analysis done by a third party as soon as the harvest is complete each year. We use the Folin-ciocalteu method for phenol testing.

What does EVOO stand for?

“EVOO” stands for “Extra Virgin Olive Oil,” which is a regulated quality designation for olive oil.

How long is it safe to use olive oil after opening?

It is recommended that a bottle be consumed within 3 months of opening for maximum quality, taste and health benefits (Since EVOO has so many uses and benefits, we usually finish ours well before 3 months!). That being said, our EVOO is still safe to consume after 3 months. It will just be less fresh, tasty or health-benefiting.

How is extra virgin olive oil different from regular olive oil?

The different qualifiers for olive oil reflect the point at which the olive oil was first extracted. "Extra virgin" olive oil comes from the very first press of the olive. “Virgin” olive oil comes from the second press. Finally, “pure” or regular “olive oil” can be from the third or 4th press. In addition, in order to be deemed extra virgin, olive oils must have a polyphenol content of at least 55 mg/kg, as measured at the time of harvest. All Kosterina EVOO has a polyphenol content of over 400 mg/kg. We, of course, don’t recommend you consume anything except pure extra virgin olive oil!
