Harvest, Transport, and Prep

The process of making olive oil starts in the grove, with the olive tree, which is usually in the ground from September to January. Farmers pick olives when they are at their brightest color and get them to the mill quickly so they don't go bad.

The olives are washed, smashed, and then turned into olive paste, which is made of olive pulp, olive stones, and olive skin. For cold extraction, the paste is slowly mixed below 27 °C, joining oil droplets to make oil with a rich flavor and high quality.

  • Step 1 – Harvesting: Collect ripe olive fruit by hand or mechanical shakers.

  • Step 2 – Transport: Move to the mill within 48 hours to avoid fermentation.

  • Step 3 – Washing: Remove dust, leaves, and stems before processing.

  • Step 4 – Crushing: Olives are ground into smooth olive paste for the next stage.

  • Step 5 – Malaxation: The paste is mixed slowly under low temperature to form a consistent emulsion.

  • Step 6 – Modern method: Traditional stone pressing and woven mats are now replaced by a continuous process using stainless-steel mills for cleaner results.

Extraction, Separation, and Finishing

Once the olive paste is ready, a continuous method is used to start the extraction process. It is spun in centrifuges to separate the oil, vegetable water, and solid pomace without adding heat. The oil extraction process keeps going through vertical separators, which make extra virgin olive oil and virgin olive oil.

Some makers leave it cloudy as Olio Nuovo to get the strong, raw flavor they want, while others filter and store it to keep the quality stable.

  • Step 7 – Separation: Centrifuges rapidly divide oil from solids and water.

  • Step 8 – Filtration: Clear oils last longer; unfiltered ones offer bold, fresh taste.

  • Step 9 – Storage: Keep olive oil in stainless tanks at 15–18 °C away from light and air.

  • Step 10 – Bottling: The clean oil is filled in dark bottles to preserve freshness.

  • Step 11 – Reuse: Remaining pomace and stones are recycled into animal feed or fuel, completing a sustainable production process.

Is Olive Oil Made from 100% Olives?

What “Extra Virgin” Really Means

Real extra virgin olive oil comes only from olives that have been squeezed out mechanically at 27 °C without using any chemicals or heat. The oil must have an acidity level of 0.8% or less and pass a taste test for balance and smell.

Due to this, fine Italian olive oil and other certified olive oils stay 100% pure and made naturally. T hey are never blended or refined.

  • Grade Standards: Extra Virgin ≤ 0.8 %; Virgin ≤ 2 %; Refined ≤ 0.3 %.

  • Mechanical Purity: Cold-pressed only, no solvents, no additives, just fruit.

  • Sensory Proof: Peppery bite and grassy aroma confirm true extraction.

  • Origin Integrity: Italy, Spain, and Greece enforce strict certification laws.

How to Spot Authentic Bottles

Real olive oils tell their story before you open them. Check for the year of harvest, dark glass packaging, and quality seals such as DOP, COOC, or NAOOA. A real extra virgin has a bright green-gold color, a fruity beginning, and a clean finish. The smell of flat or waxy means that it has been refined or diluted.

  • Color Signal: Fresh, green-gold tones hint at early harvest olive fruit.

  • Seal of Trust: Official stamps confirm 100 % olive oil origin.

  • Protective Bottle: Dark glass shields delicate polyphenols from light.

  • Smart Storage: Keep sealed, cool, and upright to preserve flavor and nutrients.

Evidence-Based Health Benefits

Extra virgin olive oil is always shown to be good for your heart and brain by science. The polyphenols and vitamin E in it protect against oxidation, and the monounsaturated fats lower bad cholesterol and raise good cholesterol.

This oil keeps its nutrients and rich flavor when cooked at low temperatures, making it a great choice for healthy diets.

  • Natural Strengths: Loaded with antioxidants, vitamin E, and healthy fats.

  • Cardio Support: Regular use lowers LDL and stabilizes blood pressure.

  • Cultural Proof: Foundation of the Mediterranean diet’s longevity link.

  • Kitchen Benefit: Retains nutrients up to typical sauté temperatures.

Balanced Viewpoints

Even though olive oil is high in nutrients, it is also high in calories, so it is important to watch how much you eat. Extra virgin olive oil has more antioxidants than regular olive oil. Refined oils are better for frying at high temperatures. Olive oil is better for you in the long run than butter or shortening without losing taste.

  • Energy Density: Roughly 120 calories per tablespoon, use modestly.

  • Smarter Choice: Replace animal fats to improve daily nutrition.

  • Refinement Impact: Virgin types hold more natural compounds.

  • Bottom Line: Quality oil, sensible use, and variety ensure the best results.

The Real Numbers

No country makes 70% of the world's olive oil. Spain makes about 40–45% of it, but that depends on the harvest year. Based on the weather and harvest times, these areas, along with Italy, Greece, and Tunisia, make up about 80% of the world's olive oil. Their combined expertise defines worldwide oil quality and consistency.

  • Top Producer: Spain supplies about 45–50 % of total output.

  • European Core: Italy and Greece focus on premium grades and blends.

  • Seasonal Shifts: Weather and rainfall change annual yields.

  • Global Share: Mediterranean nations dominate modern olive oil extraction.

Why Spain Dominates

Millions of olive trees grow in the fertile valleys of Andalusia. These trees help Spain become the world leader in oil production. To extract high-quality extra virgin olive oil quickly, large co-ops use advanced mills and a continuous method. Sustainable farming and new ideas from the EU make Spanish oils clean, reliable, and consistent around the world.

  • Ideal Climate: Dry summers and mild winters favor the olive tree.

  • Modern Technology: Centrifuge-based extraction process improves yield.

  • Sustainability Effort: Pomace recycled as animal feed and fuel.

  • Export Power: Spain remains the benchmark for global olive oil trade.
