Olive Oils

Use extra virgin olive oil (EVOO) for finishing, dressings, and low-to-medium-heat cooking because it has more flavor and antioxidants; choose refined or light olive oil for high-heat cooking as they have higher smoke points and milder flavor

"Extra virgin" denotes oil pressed from olives without heat or solvents and meeting chemical and sensory standards for low acidity and favorable flavor; it generally indicates higher levels of natural polyphenols and a stronger, fruitier taste compared with lower grades

Look for a harvest or best-by date to assess freshness, a country or region of origin (single-origin often indicates more consistent flavor), and third-party certifications like PDO/PGI or USDA organic to verify provenance and production standards

Quality olive oils typically range from budget bottles under $20 to specialty bottles over $50; higher prices often reflect factors like single-origin harvests, early cold-pressing, and certification, but value depends on freshness, intended use, and personal taste rather than price alone

Store olive oil in a cool, dark place away from heat and light, in a tightly sealed container—dark glass or stainless steel is best—and use it within 12–18 months of harvest or within a few months after opening for best flavor

Choose extra virgin olive oil for higher levels of monounsaturated fats and polyphenols linked to cardiovascular and anti-inflammatory benefits, but remember it is calorie-dense, so use in moderation as part of a balanced diet

Off or rancid smells (stale, cardboard-like) and flat, muted flavors indicate staleness; unusually neutral taste for an EVOO, vague origin statements, or lack of harvest date can be warning signs of poor quality or blending with lower-grade oils
