VERY GOOD PRODUCT

This olive oil is really good marks the food has a good flavor it's really good quality oil I love it but it's just a little too expensive just because I use it for all my cooking because it's so damn good 😋😋. Thank you for coming up with it I will be ordering it again in the future.

THE KIDS LOVE IT

We put Kosterina olive oil on everything but my kids especially love dipping their vegetables in it and I love knowing that they are increasing their intake of veggies while at the same time getting a great source of healthy fat!
