Understanding the quality of extra virgin olive oil
What really makes the quality of an extra virgin olive oil? Why do some oils develop more complex aromas, better stability, and superior nutritional richness?
The quality of an olive oil never depends on a single criterion. It results from a combination of factors: the olive variety, growing conditions, harvest timing, speed of extraction, manufacturing processes, and the analyses conducted after production.
This guide brings together the main reference points for understanding the criteria that define a high-quality extra virgin olive oil. You will discover the role of polyphenols, acidity, cold extraction, analytical testing, and early harvesting, in order to better appreciate what distinguishes a great olive terroir.

Key takeaways: the 6 indicators of a quality extra virgin olive oil
Not all extra virgin olive oils are created equal. Behind this designation lie significant differences in freshness, aromatic richness, and production quality. Certain indicators help us better understand what makes an oil excellent.
Low acidity
Free acidity is an indicator of the sanitary condition of the olives and the level of production control. The lower it is, the healthier the olives were and the faster they were processed. However, it does not provide information about the oil's taste.
Richness in polyphenols
Polyphenols are antioxidants naturally present in olives. They contribute to the oil's stability, its slight bitterness and pungency, and are associated with the benefits of the Mediterranean diet.
Cold extraction
Extraction using mechanical processes at low temperatures helps preserve the aromatic and nutritional compounds naturally present in the olive.
Harvesting at the right time
The maturity of the olives directly influences the aromatic profile of the oil. Harvesting at the optimal moment is a balance between aromatic intensity, quality, and yield.
Rapid processing
The shorter the time between harvest and extraction, the better the olive's natural aromas and qualities are preserved.
Regular analyses
Physico-chemical and organoleptic analyses verify the oil's compliance, as well as ensure its quality and stability over time.
The quality of an olive oil never rests on a single figure. It results from a set of agronomic, technical, and human choices made throughout its production.
Our commitment
At Casa Montero y Bianchi, every harvest is designed to preserve the integrity of the fruit from the tree to the bottle.
The olives are picked at their optimal maturity, then transported quickly to our mill to be extracted exclusively using cold mechanical processes. This speed of execution limits the fruit's oxidation and allows us to retain all of its aromatic richness.
Each batch is subject to physico-chemical and sensory analyses to verify its compliance with extra virgin olive oil standards and to measure indicators such as acidity or polyphenol content. For us, these data are quality control tools, just like tasting.
However, we believe that numbers only take on their full meaning when they serve a simple conviction: a great olive oil must, above all, provide a tasting emotion that is faithful to its terroir and its fruit.
Because quality is not just stated: it is measured, tasted, and built at every stage of production.
