The 2025 olive oil campaign has concluded, and with it a new chapter in the history of Colli Borbonici® , among the Campania hills where the olive tree has always been part of the landscape and culture.
The weeks of harvest, punctuated by the sound of the nets and the intense aroma of freshly picked olives, have given rise to an oil that captures the identity of the area: authentic, balanced, and naturally rich.
This year's climate—with mild temperatures and little rain at key times—favored ideal ripening, enhancing the concentration of polyphenols and the aromatic balance of our oil.
As we do every year, we completed production by subjecting the oil to chemical analysis and a sensory panel test , two fundamental tools for ensuring quality and transparency.
This approach, which we constantly repeat, is part of our commitment to those who choose Colli Borbonici® : to offer not just a product, but also concrete proof of its value.
Chemical Analysis: The Objective Basis of Quality
Chemical analyses are the starting point for certifying an extra virgin olive oil.
They check objective parameters such as free acidity , peroxide value , K232 , K270 and ΔK , indicators that tell the freshness, stability and purity of the product.
In the 2025 analysis report , all values fall well within the limits of the extra virgin category.
In addition to the mandatory parameters, we analyzed the total polyphenol content, which stands at around 730 mg/kg — a high value, synonymous with an oil rich in natural antioxidants and with a strong sensorial identity.
Furthermore, the oil has an oleic acid content of over 70% , a recognized indicator of high quality and oxidative stability . Oleic acid, together with polyphenols, helps preserve the oil's flavor, structure, and longevity, making it healthier and more resistant to aging.
These results confirm that our oil fully complies with the purity and authenticity standards set by Regulation (EU) 2568/91 and subsequent amendments.
In practical terms, this means that Colli Borbonici® 2025 Extra Virgin Olive Oil is a product of the highest quality , the fruit of healthy olives, harvested at the optimal time and milled quickly to preserve all their properties.
Panel test: a voluntary choice for transparency
In addition to the chemical analyses, this year we also decided to subject the oil to a sensory panel test , an examination conducted by a group of professional tasters recognized by the Salerno Chamber of Commerce .
The panel test is not mandatory for non-DOP oils, but we consider it an integral part of our production philosophy: a form of sensory self-certification that attests to the true quality of the oil.
During the tasting, the judges evaluate the presence of any defects and the intensity of positive notes such as fruitiness, bitterness and spiciness .
The panel confirmed that our 2025 oil is free of defects and perfectly meets the “Extra Virgin Olive Oil” category.
Panel test results 2025
-
Prevalent defect: none
-
Fruity median: 3.4
-
Median bitterness: 3.8
-
Average Spicy: 4.6

Final evaluation: Extra Virgin Olive Oil
The sensory profile is typical of high-hill oils: a balanced green fruitiness, with herbaceous hints and notes of artichoke and almond, balanced by an elegant bitterness and a decisive spiciness.
The harmony between these elements is tangible proof of a fresh oil, rich in polyphenols and made with artisanal care.

Transparency and continuous improvement
Publishing the results of our analyses every year is a practice that is part of our identity.
It is not only a gesture of transparency towards the customer, but also a way to monitor quality over time , to compare different vintages and to continue to improve.
In an industry where trust is a rare asset, Colli Borbonici® chooses clarity: numbers, data, and real flavor.
Each bottle tells the same story of consistency, respect for nature, and dedication to quality.
For us, quality isn't just a word, but a journey. And the 2025 harvest is the ultimate proof of this.
