What Is Cold Pressing? The Key to a Top-Quality EVOO Main KW: cold pressing olive oil

Among the many terms we hear in the world of olive oil, few spark as much curiosity and confusion as the famous “cold pressing.”
For food lovers, chefs, gourmet distributors, or conscious consumers, understanding this concept is not only important—it’s essential for making informed decisions.

Today, the most accurate technical expression is “cold extraction,” as technology has advanced beyond traditional pressing methods. However, the principle remains the same: to preserve the best of the fruit, respecting its integrity and organoleptic properties.

Why does this matter to you?
Because if you're looking for an Extra Virgin Olive Oil (EVOO) that truly retains all its benefits—from flavor to natural antioxidants—you need to understand what this process involves and how to recognize a truly high-quality oil.

 

A Bit of History: From Esparto Mats to the Modern Centrifuge

For centuries, oil was extracted using capachos (woven esparto mats), where ground olives were layered and slowly pressed. While romantic and rich in tradition, this method had significant limitations: impurities, risk of oxidation, and low efficiency in preserving aromas and nutrients.

The revolution came with the modern oil mill: stainless steel systems, absolute cleanliness, and strict temperature control. Instead of pressure, a continuous mechanical process of kneading and centrifugation is used—much more hygienic, precise, and efficient. This produces pure oil, without the need for chemical refining, preserving the virgin essence of the fruit.

 

The Cold Extraction Process, Step by Step

Producing a top-quality EVOO, like those made by Verde Esmeralda Olive, is no accident. It’s the result of a meticulous protocol that begins well before harvest, with its most critical phase during extraction.

1. Night Harvesting
As explained by Verde Esmeralda, olives are harvested at night, when temperatures stay below 20°C, avoiding thermal damage to the fruit.

2. Washing and Grinding
The olives are washed with potable water and ground into a uniform paste. No hot water or thermal processes are used.

3. Controlled Kneading
The paste is slowly mixed to release the oil. Here, temperature is precisely controlled, never exceeding 27°C. This limit is established by law to officially qualify as “cold extraction.”

4. Centrifugation
Instead of pressing, a high-speed centrifuge is used to separate the oil from water and solids. The result is a golden, aromatic, vibrant liquid—the true juice of the olive.

 

Why Is Low Temperature So Crucial? The Hidden Benefits

You might think 27°C is just a low number, but behind it lies powerful scientific reasoning. Extracting oil below this threshold brings three key benefits:

1. Preserves Aromas and Volatile Flavors
Many compounds responsible for EVOO’s fruity flavor, balanced bitterness, and signature spiciness are volatile—they evaporate with heat. Avoiding high temperatures keeps these aromas intact.

2. Maintains Polyphenols and Antioxidants
Polyphenols like oleocanthal and oleuropein are natural antioxidants with anti-inflammatory, anti-cancer, and heart-protective effects. Cold pressing ensures optimal levels of these compounds.

3. Preserves Vitamins, Especially Vitamin E
Vitamin E, known as the “skin vitamin,” is fat-soluble and heat-sensitive. A cold-extracted EVOO preserves it in its most bioavailable form, turning each spoonful into a dose of preventive wellness.

 

How to Identify a Truly Cold-Extracted EVOO

In today’s label-saturated market, it’s vital to recognize genuinely premium oil. Here are some key tips:

✔ Legal Labeling
Look for terms like “cold extraction” or “obtained at a temperature below 27°C.” This is a legally regulated guarantee, not just a marketing claim.

✔ Price and Origin
Authentic, early-harvest EVOOs like those from Verde Esmeralda are priced higher. Why? Because they require more olives per liter and much more careful processing. Excellence isn’t improvised.

✔ Taste and Aroma
Cold-pressed oil has an intense fruity flavor, with notes of green almond, tomato, and freshly cut grass. Balanced bitterness and spiciness are signs of rich antioxidants.

✔ Texture and Color
While color alone isn’t a quality indicator, a good EVOO often has emerald green or golden tones. Its texture is dense, elegant—almost creamy.

What is the best Spanish extra virgin olive oil for quality and price?

The best value comes from choosing a cold-extracted EVOO, ideally certified with quality seals like DOP (Protected Designation of Origin) or IGP (Protected Geographical Indication). Investing in a premium oil—especially early harvest varieties—means investing in superior flavor and health benefits, offering a much greater overall value.

What are the main characteristics of Picual olive oil?

Picual, the queen varietal of Jaén, produces a bold and fruity olive oil with hints of tomato leaf and fig. On the palate, it’s structured and well-balanced, with pronounced bitterness and spice—signs of its high polyphenol and antioxidant content.

Where can I buy authentic Jaén olive oil online?

To ensure authenticity, the best choice is to buy directly from producers based in Jaén. Premium brands like Verde Esmeralda Olive offer direct-to-consumer sales through their official online store, guaranteeing freshness and traceability.

What are the main differences between Spanish olive oil and U.S. olive oil?

Spanish olive oil stands out for its centuries-old tradition, vast range of native olive varieties, and strict quality standards. In contrast, U.S. olive oil is newer to the market, with less sensory complexity and lower regulation. Spain, the world’s top producer, is known for cultivars like Picual and Hojiblanca, which yield rich, fruity, golden oils. Italy, with its regional diversity, often produces greener, spicier profiles.

Why should I buy Spanish olive oil directly from the producer?

There are three major advantages: freshness (thanks to a shorter supply chain), authenticity (you know exactly who made it, how, and where), and access to exclusive editions—like early harvest batches that are rarely found in supermarkets.

What’s the difference between extra virgin olive oil and other types?

EVOO is mechanically extracted—never chemically refined—and retains all its nutrients and complex flavors. In contrast, refined oils go through chemical processing, which strips away antioxidants and taste. EVOO must also have an acidity of less than 0.8%, unlike lower-grade oils.

What makes Verde Esmeralda Olive oil so special?

Verde Esmeralda represents the pinnacle of premium EVOO. Its uniqueness lies in its early, night-time harvest, which preserves its aromatic profile; in its handpicked olives from Jaén; and in its iconic gemstone-shaped bottles. It’s not just olive oil—it’s a true gourmet luxury experience.

How can I identify a high-quality Spanish extra virgin olive oil?

Check the label for “cold extraction” and a clear harvest date. Choose dark glass bottles to protect the oil from light. When tasting, it should offer a fresh, fruity aroma (like grass, green fruit, or tomato) and a vibrant flavor with some bitterness and spice—hallmarks of freshness and a high polyphenol content.

What are the health benefits of Spanish extra virgin olive oil?

EVOO is a cornerstone of the Mediterranean Diet. Rich in heart-healthy monounsaturated fats, it helps lower cholesterol and supports cardiovascular health. Its polyphenols offer natural anti-inflammatory and antioxidant benefits, while vitamin E promotes cellular protection and slows aging.

How do I know if an EVOO is truly premium?

Look for these indicators: cold-pressed, low acidity (below 0.5%), an aromatic fruity nose, and a well-balanced taste with slight bitterness and spice. Premium oils often come in dark bottles to protect their properties and are harvested early for maximum quality.
