The 3-Second Check That Separates Real EVOO from the Rest

Look for one sentence on the label: "Extra Virgin Olive Oil — Cold Pressed in Italy from Olives Harvested in Italy." If it's there, the oil is real, traceable, and made without chemicals.

Heart health and nutrition benefits of extra virgin olive oil

Nutrition & Health Benefits of Olive Oil

Olive oil is more than flavor—it's also a source of nutrients that support a balanced diet. It delivers mainly monounsaturated fats and natural antioxidants, making it a smart swap for saturated fats in everyday cooking. According to Harvard Health, replacing saturated fats with unsaturated ones helps promote heart-healthy eating patterns.

  • Healthy fats: Mainly monounsaturated, supporting balanced nutrition.
  • Vitamins: Source of vitamin E and other antioxidants.
  • Polyphenols: Natural compounds that protect oil freshness and add peppery flavor.
  • Freshness: Harvest date matters—enjoy within 12–18 months for peak quality.

FAQs — Learn About Olive Oil

What is extra virgin olive oil?
The highest-quality olive oil, mechanically extracted without heat or chemicals, with acidity below 0.8%. It preserves natural flavors, antioxidants, and polyphenols.
Can I cook with EVOO?
Yes — use medium heat for sautéing and roasting. High-polyphenol EVOO has a smoke point around 190–210°C. Drizzle to finish for best flavor and maximum nutrition.
How do I store olive oil?
Keep it cool, dark, and tightly closed — away from heat and light. Use within 12–18 months of the harvest date for peak freshness and polyphenol levels.
Is olive oil healthy?
It provides mainly monounsaturated fats, vitamin E, and natural antioxidants including polyphenols. Enjoy as part of a balanced diet. Always check lab data for polyphenol content.
Where is the harvest date on an olive oil bottle?
Look for "Harvest Date," "Raccolto," or "Campagna" followed by a month and year — typically on the back label or neck. Deliba prints it prominently on the front label. If a bottle only shows a "best by" date, the harvest date is hidden: subtract 18–24 months to estimate it. A genuine harvest date always includes both month and year, never just a year.
What are polyphenols in olive oil?
Polyphenols are natural antioxidant compounds found in extra virgin olive oil. They're responsible for the peppery, slightly bitter notes you feel at the back of your throat. Higher polyphenol concentration (measured in mg/kg) is associated with greater freshness, earlier harvest, and potential health benefits. Deliba Ottobratico contains 629 mg/kg of total polyphenols, independently verified.
