958 mg/kg of polyphenols. 🫒 But what does that number actually tell you about your olive oil?
At Vignoli, we believe quality goes beyond what’s written on the label. Our Coratina single-varietal EVOO was tested again nine months after production, and it still showed 958 mg/kg of polyphenols.
These naturally occurring compounds contribute to olive oil’s antioxidant properties, influence its distinctive bitterness and peppery finish, and help us better understand its quality.
Because great extra virgin olive oil isn’t just about what’s in the bottle today. It’s also about how well its quality is preserved over time.
