The Vetralla Facility, known as Frantoio Cesare Battisti, is one of OP LATIUM‘s reference facilities. In the heart of Tuscia, it works closely with local producers to enhance the value of the area’s olives and turn them into certified, traceable extra virgin oils. Within OP LATIUM’s network it plays a very concrete role: it is a collection, processing and technical support point for farms.
Tuscia, a land of olive trees
Vetralla and the whole of the Tuscia area of Viterbo have been olive-growing land for centuries: hills of volcanic origin, rich soils and a climate that favours the slow ripening of the drupes. It is in this setting that the mill operates, collecting olives from a suited local area and processing them close to where they are produced — a decisive advantage, since reducing the distance and the time between harvest and milling is one of the keys to quality.
The Monovarietale Caninese
Among the mill’s most representative products is the Monovarietale Caninese extra virgin oil, made from selected Caninese olives — a variety typical of the area, valued for its cold resistance and for a bold profile, with vegetal, artichoke notes and a slightly pungent finish. The olives are processed with a continuous two-phase plant and fast cold milling, which preserves the varietal characteristics while keeping to a minimum the time between harvest and processing. It is an oil designed for the attentive consumer, but also for restaurateurs and specialist shops looking for a distinctive extra virgin, ideal for enhancing simple, well-defined dishes.
The choice of a single-variety oil is no accident: working a single cultivar means putting the pure character of the Caninese in the glass, without the mediation of a blend. It’s a way of telling the story of the area through its most distinctive variety, and of offering tasters a precise, recognisable reference point year after year.
What two-phase cold milling means
Behind a label like “cold extracted” lies a precise technical choice. The two-phase plant separates the oil from the solid part using less water than traditional three-phase systems: this way fewer polyphenols and aromas are dispersed, staying in the oil rather than ending up in the processing water. Cold processing, meaning below the temperature thresholds set by regulations, protects the most fragile and delicate substances. The result is an extra virgin oil that retains its aromas, freshness and that store of polyphenols that determines its taste and shelf life.
Quality certifications and traceability
The facility is authorised to produce oils with national and EU certifications:
- Tuscia PDO
- Olio di Roma PGI
- Organic
These are recognitions that go beyond just the name on the label. Tuscia PDO links the oil to a defined area and a verified specification; Olio di Roma PGI identifies a product from the Lazio region with its own rules; the organic certification attests to a cultivation method free of synthetic chemicals. Every stage is tracked and documented, from the origin of the olives through processing to bottling: transparency for producers and trust for consumers. Here, certifications are not just a label but a working method built on clear, consistent parameters.
Concrete services for farms
Frantoio Cesare Battisti offers various services to olive-growing farms, whether OP LATIUM members or not:
- Contract milling, by appointment and with quality control;
- Agronomic and administrative technical advice for certifications and grant applications;
- Agricultural equipment inspection, in particular calibration of sprayer equipment.
The facility is organised to meet farms’ needs even during peak harvest periods. For many small local producers, having a well-equipped mill and nearby technical support available makes a huge difference: it allows them to process their own olives at the right time, to professional standards, without having to take on investments beyond their means.
A mill with solid roots
The Vetralla mill has been active for years and has helped strengthen the area’s agricultural network. Part of a larger system, it maintains a direct link with the local area and its producers: through promoting local cultivars like the Caninese, its focus on certifications and its concrete services, it strengthens the extra virgin olive oil supply chain in Lazio. It is a fixed point for those who grow olives in Tuscia — a place where the area’s olive-growing tradition meets modern, controlled working methods.
