Cold Pressing Olive Oil: What It Is, How It Works, and Why to Choose It

Often, when we buy a bottle of olive oil, we read the label: cold pressed. What does this technique mean, how does it work, and why choose it if we want to make oil at home? There are several stages that make up the cold pressing process: we will discuss them below.

What is cold pressing olive oil?

What is the meaning of cold-extracted oil? Cold oil pressing occurs through a mechanical process; during the extraction phase, the temperature is below 27 °C. However, this temperature is linked to extra virgin olive oil; it increases if you wish to try your hand at other vegetable oils. It is called this because of the temperature of the crushed olive paste and serves to maintain the physical and nutritional characteristics of EVO oil.

Stages of the process: from milling to pressing

The mechanical process follows rigorous stages: in ancient times it happened differently, as stone wheels were used to rotate over the olives, which were only then pressed. Today, of course, we can use specific machinery and equipment for pressing olives. New technologies are also essential for controlling and guaranteeing the standards of extra virgin olive oil production. It all begins with the harvesting of the olives and their accurate washing: this is where we remove leaves, twigs, and impurities, so as to work only with healthy fruits.

Then we move on to cold milling, a phase in which the olives are crushed until they turn into a soft paste. This is followed by malaxation, a slow and continuous stirring that allows the tiny oil droplets to combine and become easier to separate. The heart of the process is cold pressing: the paste is subjected to mechanical pressure, without adding heat, and from this, the liquid part, rich in oil, is separated from the solid part.

Finally, a final filtering phase delivers a clear product, ready to release all its nutritional and sensory value onto our table.

Fiscoli and presses: traditional tools for pressing

For centuries, cold pressing olive oil was entrusted to simple but ingenious tools, which still tell the story of rural tradition today. Among these are press mats (fiscoli), discs made of natural fibers (today also synthetic). How does it work? The olive paste is held in the fiscoli, while the liquid, rich in oil, drains into the underlying containers. Why is it useful?

They help separate the solid and liquid parts, thus obtaining a natural extraction that respects the properties of the olives. Even today, those who produce on a small scale or choose to maintain the traditional method rely on these tools. To learn more, here you will find a selection of oil mats, available in different sizes. Those looking for practical information, such as the prices of press mats for oil mills, can orient themselves by evaluating the various formats, to find the most suitable solution for their needs.

Difference between cold and hot pressing

One of the questions we ask ourselves most often is: is hot or cold pressing better? The answer depends on what we are looking for in the oil.

Hot pressing uses higher temperatures during malaxation and subsequent stages: a larger quantity of oil is obtained, because heat facilitates the separation between liquids and solids.

However, the downside is quality: part of the aromas, polyphenols, and nutrients are lost.

Cold pressing, on the other hand, gives us an oil rich in aromas, intense in taste, and with all its beneficial properties still intact. This is why it is considered the best choice for those who focus on quality.

Pressing vs. cold extraction: the differences

Cold pressing works on the olive paste through pressure: by compressing the mass, the oil naturally separates from the other components. Cold extraction, on the other hand, uses modern plants and metal blades that facilitate the division between oil and water. In fact, the first method takes us back to traditional gestures, with slower and more manual steps. Cold extraction, on the other hand, follows a faster and more linear path, designed for larger productions.

Why choose cold-pressed oil

The reason is simple, and the answer lies in the process itself, a true guarantee of quality. It means that throughout the processing, the temperature never exceeded 27 °C, thus preserving the aromas and precious substances contained in the olives. But what are the advantages of cold-pressed oil?

First of all, its organoleptic richness: the fruity aroma, the decisive taste with bitter and spicy notes, the intense color. Then the nutritional part: polyphenols and vitamins. Finally, stability: a cold-pressed oil, if well preserved, maintains its characteristics longer.

Where to buy cold pressing tools: Vivi in Campagna's selection

Those who choose to produce oil in a traditional way know that olives alone are not enough: tools designed for each stage of the process are needed. Among these, the most characteristic are the fiscoli, true allies: resistant, washable, reusable. Today we can find oil mats of different sizes, suitable for every need.

To obtain high-quality oil even with traditional pressing, it is essential to rely on safe and efficient equipment. On Vivi in Campagna, you will find a selection of press mats for presses and oil mills, ideal for both small producers and farms that want to keep the link with tradition alive.
