In the olive oil sector, profitability does not depend solely on production volume or market prices. The real factor that differentiates the most competitive olive oil mills is EVOO quality.
A high-quality Extra Virgin Olive Oil not only achieves better prices, but also opens the door to premium markets, international competitions, and customer loyalty. Improving quality therefore means investing in sustainable profitability and in long-term profitability in olive oil mills.

Harvesting olives at veraison (when olives change from green to purple) usually results in lower oil yield, but higher sensory quality and polyphenol content.
Benefits:
Positioning in gourmet segments.
Awards and recognitions that act as free marketing.
Possibility of selling at significantly higher prices.
EVOO quality begins in the olive grove, not in the mill.

A common mistake is storing olives before milling. This causes fermentations and sensory defects that can turn a mill into an unprofitable olive oil mill with difficulties competing in the market.
Key strategies:
Mill olives within less than 24 hours after harvesting.
Organize logistics so that reception is efficient.
Avoid large piles of olives that generate heat and deterioration.
Reducing this time is one of the most profitable decisions to guarantee quality and improve operational efficiency in the olive oil mill.
Temperature is a critical factor: above 27 °C, the oil loses aromas and antioxidants.
Practical strategies:
Constantly monitor temperatures.
Avoid overheating in pursuit of higher yield.
Invest in equipment with digital parameter control, promoting digitalization in olive oil mills and innovation in olive oil mills.
Consumers in premium markets pay for an EVOO with maximum sensory quality, not for liters produced at the expense of quality attributes.

Oil can lose quality after production if it is not stored correctly.
Ideal conditions:
Stainless steel tanks with inert atmosphere (nitrogen).
Constant temperature below 20 °C.
Protection from light and oxygen.
Poor storage turns an excellent extra virgin olive oil into a product with no added value and makes it difficult to maintain quality management in the olive oil mill.

Many producers avoid filtration to prevent volume loss, but unfiltered oil loses stability and may develop defects within a few months.
Strategy:
Filter immediately after extraction.
Communicate to customers that filtration guarantees quality and stability.
A stable oil builds trust and customer loyalty while improving EVOO traceability throughout the value chain.

Excellence cannot be achieved without trained personnel.
Key aspects:
Train mill masters and technicians in early defect detection.
Provide training in hygiene and maintenance processes.
Promote a culture of quality as a top priority and move toward professionalization in the olive oil mill.
EVOO quality depends as much on machines as on human decisions.

Quality must also be demonstrated through objective proof.
Recommended strategies:
Olive oil mill certifications such as Organic, PDO, and PGI.
Participation in international competitions.
Use analytical and sensory results as part of marketing.
Awards and certifications are credentials that justify higher prices and reinforce olive oil mill success in demanding markets.
Quality only translates into profitability when it is communicated properly.
Practical actions:
Include EVOO traceability and careful storytelling in the brand narrative.
Offer tastings and sensory experiences.
Target markets where quality is valued (gourmet niche, export markets).
A liter of high-quality EVOO positioned correctly can double or triple its price compared to standard oil.
Improving EVOO quality is not a technical whim: it is a business strategy that directly impacts the profitability of the olive oil mill. From early harvesting to storage, every decision adds or subtracts value and helps optimize the olive oil mill while improving competitiveness.
This post provides a general overview. But real transformation requires solid and strategic training.
In the ESAO Executive MBA – Olive Oil Consultant, EVOO quality is addressed as a central part of professionalization in the olive oil mill, combining technical processes, olive oil mill quality management, brand strategy, and access to premium markets.
Investing in quality means investing in the future of your olive oil mill. Professional training is the next step.
