Olive press traditional stone

Traditional stone olive press, an ancient device used to extract olive oil, still found in Mediterranean producing regions.

About this subject

Stone olive presses are a hallmark of artisanal olive oil production, with origins dating back to ancient civilizations such as the Greeks and Romans. These devices consist of a large stone wheel, usually powered by animal or human traction, that rotates over a stone base, crushing olives to release the oil. The process is slow and manual but preserves the flavor and properties of extra virgin olive oil.

Traditionally, olives were harvested and taken to the mill, where the stone press performed the first extraction step. The resulting paste was then pressed using mats or bags to separate the oil from water and solid residues. This method, though less efficient than modern hydraulic presses, is prized by producers seeking to maintain quality and tradition.

Regions such as Andalusia in Spain, Tuscany in Italy, and Alentejo in Portugal still preserve mills with these presses, often open to tourist visits. Some stone presses date back centuries and are considered cultural heritage. Olive oil extracted by this method is often marketed as a gourmet product with protected designation of origin.

Interestingly, the cold-pressing technique, which keeps temperatures below 27°C, was already intuitively practiced by the ancients, as stone grinding generated less heat than modern metal mills. Today, the traditional stone olive press is an icon of sustainable agriculture and the appreciation of ancestral methods.

Frequently Asked Questions

How does a traditional stone olive press work?

A large stone wheel rotates over a base, crushing olives. The resulting paste is then pressed to extract the oil. The process is cold-pressed to preserve quality.

Where are traditional stone presses still used?

In Mediterranean producing regions such as Spain, Italy, Portugal, and Greece, mainly by small producers and for tourism or artisanal production.

What is the difference between stone-pressed and industrial olive oil?

Stone-pressed oil is extracted without excessive heat, preserving flavor and nutrients. It is less productive but considered higher quality, often with protected designation of origin.
