Extra virgin olive oil is often called a "fat," but in reality it's something more specific: fresh fruit juice. When olives are harvested and crushed within hours, and their juice is extracted only by mechanical means, you get an oil that is closer to a fresh food than a processed ingredient.

At Borgo Naera, this is what we bottle: early-harvest olives, milled quickly and without heat or chemicals. The result is a vibrant, green-gold juice that carries not just flavour, but a dense concentration of bioactive compounds.

What makes extra virgin olive oil different from other oils

Most edible oils go through refining: high temperatures, chemical solvents, bleaching and deodorising that strip out aroma, flavour and many natural antioxidants. Extra virgin olive oil is different. By law in the EU, it must be obtained only by mechanical processes at controlled temperatures, without any chemical refining.

This gentle extraction preserves:

• Monounsaturated fats, mostly oleic acid
• Vitamin E and other minor components
• Polyphenols, the family of plant molecules that give high-quality EVOO its peppery, bitter, intensely green character

In simple terms: refined oils behave like neutral calories. True extra virgin olive oil is a food with character.

Polyphenols: what they are and what they taste like

Polyphenols are a large family of plant compounds. In olive oil there are roughly two dozen key phenolic compounds, including oleocanthal, oleuropein derivatives and hydroxytyrosol.

They are responsible for:

• The aroma of fresh herbs, tomato leaf, artichoke or almonds you smell in good EVOO
• The bitterness on the tongue and the peppery tickle at the back of the throat when you swallow, especially noticeable in young, early-harvest oils

So if an olive oil tastes flat, greasy and "easy" with no pepper or bitterness, it is usually low in polyphenols.

When can an olive oil carry the EU health claim?

The European Union authorises one claim for olive oil polyphenols: they contribute to the protection of blood lipids from oxidative stress. To carry it, an oil must contain at least 5 mg of hydroxytyrosol and its derivatives per 20 g, and the beneficial effect requires a daily intake of 20 g of olive oil.

Polyphenols decline naturally over time — often by around 30–40% over a year, depending on storage. Starting from a high level at harvest means the oil stays richer for longer. Keep your bottle away from light and heat, and use it within the year.

Where Borgo Naera stands

Our latest harvest analyses show polyphenol levels in the range of 280–400 mg/kg at bottling. Our oil has a noticeable peppery finish and structured bitterness — sensory markers of phenolic richness, not defects.

How much to use

A practical everyday range is 2–4 tablespoons (20–40 ml) per day, used instead of butter, margarine or refined oils rather than added on top of an already rich diet. This mirrors traditional Mediterranean intake.

How to recognise a high-polyphenol oil

You don't need a lab to taste what is in your bottle:

1. Pour a small amount into a cup.
2. Warm it gently in your hand and take a deep sniff. Fresh EVOO should evoke green plants, herbs, tomato vine, artichoke, almond, fresh grass.
3. Sip, hold it briefly in your mouth, then swallow.

You should notice a pleasant bitterness on the tongue, and a peppery, stinging sensation at the back of the throat that often makes you cough once or twice. That sting is linked to oleocanthal.

In the kitchen, use it generously raw — over salads, cooked vegetables, soups, grilled fish, legumes, whole grains. EVOO is more heat-stable than many people think, thanks to its antioxidants and high proportion of monounsaturated fats, but very high temperatures will gradually degrade the phenolics.

Why our farming matters here

For us, chemistry and ethics are inseparable. A bottle of olive oil is the end-point of decisions about land, water and biodiversity.

At Borgo Naera, we are committed to:

• Organic certification across everything we bottle
• Regenerative practices on our own grove, protecting soil structure and microbial diversity
• Vegan and cruelty-free production, respecting animals and ecosystems

Choosing an oil like ours is not only a flavour decision; it is a vote for a production system where what is good for the land aligns with what is good at the table.
