About Kosterina
About Kosterina
Kosterina is all about bringing the Mediterranean lifestyle to your kitchen (and even your skincare routine). Their star ingredient? Award-winning, high-antioxidant extra virgin olive oil made from 100% Koroneiki olives grown in southern Greece. Harvested in November and December, it’s the kind of oil you’ll want to drizzle on everything: bread, salads, even ice cream. (Don’t knock it until you’ve tried it!) Beyond olive oil, they offer infused vinegars, dark chocolates, and skincare products, all crafted with that same premium oil.
