Cold Pressed Olive Oil UK

What It Really Means and Why It Matters for Your Health

Cold pressed. It is one of the most commonly seen phrases on olive oil labels in the UK — and one of the least understood. Like "extra virgin" and "artisan," it has been used so widely and so loosely that its meaning has become obscured. This guide restores clarity: what cold pressing actually involves, why it matters for the quality and nutritional profile of the oil, and how to find genuinely cold-pressed olive oil in the UK market.

What Cold Pressing Actually Means

Cold pressing refers to the mechanical extraction of oil from olives at a temperature below 27°C. The olives are harvested, cleaned, and taken to the mill where they are crushed — traditionally by stone mills, more commonly today by modern stainless steel malaxers — and then passed through a centrifuge to separate the oil from the olive paste and water.

At no point in this process is external heat applied, and no chemical solvents are used. The result is an oil that retains its full complement of natural flavour compounds, volatile aromatics, polyphenols, and vitamins — exactly as nature produced them in the olive.

Why Temperature Matters

Heat is the enemy of quality in olive oil. When oil is extracted at high temperatures — as in the industrial "hot press" method used to maximise yields from lower-quality olives — the volatile aromatic compounds that give great EVOO its character are destroyed. The polyphenols that provide its health benefits are degraded. The enzymes that contribute to its nutritional value are denatured.

Hot-pressed oils can still technically qualify as "extra virgin" if their acidity remains within legal limits. This is why the extra virgin designation alone is an insufficient quality guarantee — and why cold pressing matters.

The Polyphenol Connection

Polyphenols are the family of naturally occurring compounds responsible for most of the health benefits associated with extra virgin olive oil. They include oleocanthal — a natural anti-inflammatory agent — and a broad spectrum of antioxidants that protect against oxidative stress and cellular damage.

Research has consistently shown that polyphenol content is highest in oils that are freshly pressed, cold-extracted, and consumed within twelve months of harvest. The Biancolilla variety from Caltanissetta, Sicily, is known for producing oils with particularly high polyphenol concentrations — a characteristic that the DOP certification process verifies through mandatory laboratory testing.
