Cold-pressed olive oil means oil produced by mechanically pressing olives at a temperature not exceeding 27 degrees Celsius, without chemicals or additives. This method preserves the natural flavor, aroma, and nutrients of the olives. It is precisely this method that distinguishes high-quality olive oil from industrially processed oil.
How does cold pressing differ from other manufacturing methods?
In cold pressing, fresh olives are crushed and pressed mechanically shortly after harvest. The process is purely mechanical: the olive paste is pressed in a press or spun in a centrifuge without external heating. This preserves the oil's delicate aroma compounds and naturally occurring polyphenols.
Refined olive oil, on the other hand, is produced by heating and chemical processing. The process removes color, flavor, and odor from the oil, and many beneficial compounds are lost along with them. The result is a neutral-tasting oil that can withstand higher frying temperatures but doesn't offer the same culinary experience.
Why does cold-pressed olive oil retain nutrients better?
Low pressing temperatures protect the natural polyphenols, vitamin E, and other antioxidants in olives, which degrade in heat. Cold pressing also preserves the oil's fruity aroma and greenish-gold color—signs of freshness and quality.
Extra virgin olive oil is a cornerstone of the Mediterranean diet. It naturally contains polyphenols and unsaturated fatty acids, making it a natural part of a varied daily routine. A drizzle over salad or with bread is enough to bring both flavor and nutrients.
Is cold-pressed the same thing as extra virgin olive oil?
Not quite. Cold pressing describes the manufacturing method, while extra virgin olive oil is the highest quality grade of olive oil. It requires mechanical pressing without chemicals, an acidity level below 0.8 percent, and a flawless, fruity taste. Not all cold-pressed oil automatically meets these requirements – but high-quality cold-pressed oil is almost always extra virgin olive oil.
Explore the quality grades of olive oil more precisely, you will understand the difference between extra virgin olive oil, virgin olive oil, and mild olive oil.
How to identify authentic cold-pressed olive oil in the store?
Authentic cold-pressed olive oil can be identified by its label. Check these things:
- Manufacturing method: mention of cold pressing or mechanical pressing
- Quality Category: extra virgin olive oil
- Origin: exact country of origin or region, not just "EU region"
- Variety A named olive variety, like Koroneiki, tells one origin of an oil
- Packaging dark glass or metal bottle protects oil from light
Avoid products labeled simply "olive oil" without a more specific quality indication. This usually means a blend of refined and virgin olive oil. Read frequently asked questions about olive oil, if you want to deepen your knowledge.
Cold-pressed olive oil is best suited for cold dishes.
Cold-pressed extra virgin olive oil is best enjoyed on its own and for finishing dishes. Try these uses, for example:
- A good splash of Greek salad on top of tomatoes, cucumber, feta, and olives
- For dipping fresh bread with sea salt
- To finish pasta just before serving
- For crowning soups and grilled vegetables
Better suited for frying and baking mild olive oilwhose taste is more neutral. In the Memmas Knossos range, you will find both cold-pressed extra virgin olive oil for finishing and a mild alternative for everyday frying. This way, there's a suitable oil for every use – and the flavors of Crete become a part of Finnish everyday life.
