kostas + Katerina


My husband and I both grew up with olive oil at the center of our family dinner table and now, as adults living in New York City, we rely on care packages of olive oil from our relatives back in Greece to maintain this tradition. When we inevitably run out of the good stuff, I head to the supermarket only to be disappointed with the so called "extra-virgin" oils that just don't compare in taste or quality. I created Kosterina to take the guesswork out of shopping for quality olive oil and to share our family secret with you. I believe that home cooks in the U.S. use too much butter and vegetable oil in their dishes so I'm looking to educate consumers on the power of polyphenols and the enormous health benefits of premium extra virgin olive oil. 

With love from my family to yours,




a little bit more about us

Our families are both from the Pelopponese region of Greece. My family is from a small, beautiful fishing village called Koroni, which is about one hour's drive from Kalamata. (Yes, Kalamata, as in Kalamata olives). Koroni is the home to the Koroneiki variety of olives — one of the most popular varieties in Greece. We were married in Koroni in 2014. My husband's family is from the western Peloponnese region of Laconia — also very well known for some of the best olives in Greece. We have a love for food and eat most nights at home with our friends and family. We cook very simple Greek recipes, many of which can be found on our Recipe Blog, Once Upon an Olive Tree.
