Guaranteed Fresh

EVOO from this year's harvest, made from unripe olives cold pressed the day they are picked

Single Origin

Our farmers in the Peloponnese grow our 100% Koroneiki olives using organic farming practices

Our secret: loads of polyphenols

Our olive oil is cold pressed from early harvest koroneiki olives - the most popular varietal in Greece. These young koroneiki olives are called “agourelio” in Greek, which means the olives are collected when green and raw so they have a high chlorophyll content.

The higher chlorophyll content in unripe olives makes the oil greener and richer in healthy polyphenols. You can literally taste the how fresh and healthy it is - there is a peppery sensation in your throat when you drink polyphenol-rich EVOO.

Olive oil must have a polyphenol content of 55mg/kg to be considered extra virgin.

Kosterina olive oil always has polyphenol content of more than 400 mg/kg at the time of harvest.

One Ingredient. Pure. Simple.

Our olive oil is made from 100% Koroneiki olives grown in the Peloponnese. Our farmers use organic farming practices and harvest our olives when they are still green and unripe. They are cold pressed the same day they are picked in order to maximize flavor, freshness, and polyphenol content. It takes 12 pounds of Koroneiki olives to make just one 500mL bottles of Kosterina Original Extra Virgin Olive Oil.

Wonderful Olive Oil

This is the most wonderfully authentic olive oil I've tasted in the States. The spicy and aromatic flavor brings me right to my many trips to Greece and my heart is SO happy for that (in ~all~ the ways)! I can now enjoy dousing everything I eat in olive oil because the flavor now adds so much.

I'm in love....with Kosterina EVOO!

Last year, Kosterina EVOO was given to me as a birthday gift and I have not been able to stop obsessing over it! This brand is - hand down - one of the freshest EVOOs that I have tasted...grassy, peppery, DELICIOUS!

So, so good.

We received it quickly after ordering, and it arrived in beautiful packaging. In a stunning bottle that’s perfect for any kitchen aesthetic, it’s our new favorite cooking addition. It tastes incredible, and won a blind taste test of varying olive oils we’ve collected hands down. It literally elevates any and every dish we use it on: caprese salads, poached eggs on baguettes, etc.

Awesome stuff

Arrived timely and was fresh and really truly great tasting oil. I use it daily on fresh fish and mushrooms. Results are positive in less joint pain!

Meet our Founder

My husband, Kostas, and I launched Kosterina in 2016 so that Americans could enjoy the incredible Greek EVOO we grew up with

Hi! I'm Katerina. I'm a serial entrepreneur with a passion for family, living a healthy lifestyle, and, of course, all things Greek.

My family is from a small fishing village in the Peloponnese called Koroni – the original home of the Koroneiki olive - the most popular varietal in all of Greece. Olive oil has always been at the center of mealtime, and mealtime at the center of family.

We could never find a proper substitute here in the States for the fresh, delicious Greek EVOO we knew and loved, so we partnered with farmers in the region to develop a premium, delicious Greek Extra Virgin Olive Oil for the US market.

As we began development, I became an olive oil sommelier and, in addition to learning more about what makes a delicious and healthy EVOO, discovered that the majority of the olive oils here in the US are not what they say they are. Did you know that over 69% of olive oil in US supermarkets is mis-labelled as extra virgin? When olive oil is not truly extra virgin, it is missing the polyphenol (antioxidant) content that makes it so healthy for us.
