Kosterina is a lifestyle brand rooted in the rich traditions and flavors of the Mediterranean, dedicated to helping people live healthier, happier, and more delicious lives.

Founded on the belief that fresh, high-quality ingredients can be trusted to nourish both body and soul, Kosterina champions the power of authentic Mediterranean food and skincare — where wellness and joy go hand in hand.

Inspired by the founder’s heritage from Koroni, a small fishing village in southern Greece known as the birthplace of the Koroneiki olive, Kosterina began with a mission to bring truly authentic extra virgin olive oil (EVOO) to the U.S. market.

After discovering that much of the olive oil available locally lacked genuine quality and health benefits, the founder immersed herself in olive oil education, becoming an olive oil sommelier and learning about the powerful polyphenols that define exceptional EVOO. Kosterina Original EVOO delivers over 500 mg/kg of polyphenols — nearly ten times the industry standard — ensuring an unmatched flavor and wellness profile.

Today, Kosterina has expanded beyond olive oil to offer a thoughtfully curated range of organic olives, artisanal vinegars, and all-natural skincare products harnessing the antioxidant and hydrating power of extra virgin olive oil. The brand’s philosophy centers on family, however it is defined, and embraces the joyful Mediterranean spirit — late nights, good food, wine, dancing, and the deep connection between health and happiness.

The name “Kosterina” itself is a personal testament to love and family, blending the founder’s name, Katerina, with her husband Kostas. Originally their wedding hashtag, #Kosterina became a beloved nickname among friends and family, making it the perfect identity for a brand born from passion, tradition, and authenticity.
