A Note From Our Founder
My family is from a small fishing village called Koroni in the center of olive country in southern Greece. Koroni is the original home of the Koroneiki olive – the most popular varietal of olives grown throughout all of Greece – so, I grew up knowing what good olive oil tasted like.
As I started my own family, I started cooking more at home. I found that the Greek “extra virgin” olive oil at the supermarket here tasted absolutely nothing like what my family produced and enjoyed in Greece. I knew I wanted to bring the good stuff to the US. As I began development, I took an olive oil sommelier course and I was blown away by the health benefits of olive oil when harvested early and milled properly. I learned about the polyphenols found in EVOO and the story of the research team that discovered them.
I also discovered that the majority of the olive oils sold in the US are not what they say they are so I decided to focus my efforts on making an EVOO that is authentically Mediterranean, delicious to smell, taste, and cook with, and, above all, loaded with health benefits. In order to be deemed extra virgin, an olive has to have 55 mg/kg of polyphenol content. Kosterina Original EVOO always has greater than 500 mg/kg, 8-10x more than your typical olive oil.
Today, Kosterina has evolved to be so much more than olive oil. We’ve created an incredible line of organic olives, vinegars that pair perfectly with our EVOO, and even all natural skincare leveraging the power of extra virgin olive oil for deep hydration and antioxidant protection.
Our Olive Oil Love Story
Kosterina is the combination of my full name (Katerina) and my husband’s name (Kostas) and #Kosterina was actually created as our wedding hashtag (which you can read more about here). After our wedding, our friends and family continued to call us Kosterina. So, when I wanted to launch an olive oil brand centered around love and family, with a name that sounded Greek, Kosterina was the natural choice. Oh, and we also already owned the URL.
The Origin of Our Oil
In Greece, extra virgin olive oil is the center of meal time, and meal time the center of family. Fresh, authentic antioxidant-rich Greek extra virgin olive oil has a grassy aroma and peppery finish. That’s the olive oil our founder knew from visiting family in Koroni, a small fishing village in Greece. But back in the U.S., the oil was nothing like the antioxidant-packed EVOO proven to naturally reduce the risk of disease; it was flavorless at best and rancid at worst.
Taste is an indicator of quality, and too many Americans are not only missing out on irresistible EVOO flavor, but also the antioxidant superpowers derived from olives that are harvested early and cold-pressed. Eager to bring the golden, fresh olive oil back to the U.S., in 2016, Katerina and her husband Kostas began to source the luscious olive oil so ubiquitous in our ancestral homeland of Greece.
From Our Groves to Your Kitchen
Each bottle of Kosterina Original Olive Oil contains 12 pounds of early harvest, single-origin Koroneiki olives straight from the groves of southern Greece. Our farmers use organic farming practices and harvest the olives when they are unripe. These olives yield a small amount of concentrated juice that’s packed with bold flavors, otherwise lost as olives ripen. The olives are cold-pressed the same day they’re picked, meaning that fresh, grassy flavor is bottled up instantly. The result? The ultimate EVOO, bursting with maximum polyphenols and maximum flavor.
The Grecian Elixir
Beauty from the inside out. Adding our EVOO skincare to your daily routine is like taking a quick trip to the Mediterranean seaside: nourishing and needed. Like our Ancient Grecian ancestors, we at Kosterina recognize the power of antioxidant-rich extra virgin olive oil for skin. A swipe of our balm or a drop of our face oil will leave your skin feeling moisturized, calm, and free of toxins.
