Understanding Olive Oil

Harvesting

Early Harvest
Green olives picked Oct–Nov. High polyphenols — robust, peppery, and intensely fresh. Preferred for premium EVOOs.
Late Harvest
Fully ripe black olives yield milder, fruitier oils with softer finish and lower antioxidant content.
Harvest Date
Most premium producers print the harvest year on the label. Always the key freshness indicator — more meaningful than the bottling date.

Processing

Cold-Pressed
Temperature below 27°C (80°F). Preserves volatile aromatics, health compounds, and delicate flavors lost at higher temperatures.
Speed
Milling within 4–6 hours of harvest produces the most vibrant, freshest-tasting oils. Oxidation begins immediately after picking.
Two-Phase
Modern continuous centrifuge without added water — reduces oxidation and maximises polyphenol retention vs. older three-phase milling.

Grading & Quality

Extra Virgin
Free acidity ≤ 0.8%. Zero sensory defects. Produced by mechanical means only — no heat or chemical solvents. The highest grade.
DOP / IGP
Protected designation of origin certifications regulate which varieties and production methods qualify for specific regional labels.
High-Phenolic
Oils above 250 mg/kg polyphenols. Associated with the strongest health benefits. Bold, often peppery, with exceptional shelf life.

Storage

Light
UV exposure degrades oil rapidly. Always use a dark glass bottle or opaque tin — never store in a clear container on a sunny counter.
Temperature
Store below 20°C, away from heat sources. A cool, dark pantry is ideal — not above the stove or near an oven.
Shelf Life
Consume within 12–18 months of the harvest date. Freshness fades after opening — use within 6 weeks of uncorking.

Tasting

Fruitiness
Primary attribute: aroma and flavor from fresh, healthy olives. Assessed both when inhaling and after tasting.
Bitterness
Felt at the centre of the palate. A positive sign of fresh, polyphenol-rich oil — never considered a defect in quality EVOO.
Pungency
Throat burn from oleocanthal — a natural anti-inflammatory. The intensity signals freshness. One cough = good. Two coughs = exceptional.

Polyphenols

Oleocanthal
The main pungent phenol — ibuprofen-like anti-inflammatory activity. Responsible for the characteristic throat burn of fresh EVOO.
Oleuropein
The predominant bitter phenol. Linked to cardiovascular and neuroprotective benefits. Higher in early-harvest, robust-intensity oils.
Measurement
Polyphenol content measured in mg/kg. Values above 250 are considered high-phenolic; above 500 are exceptional.
