Understanding Olive Oil Grades

Before we dive into the specific types to avoid, let's first understand the grading system used to categorize olive oil. The International Olive Council and many regulatory bodies classify olive oil into four main categories:

1. **Extra Virgin Olive Oil (EVOO):** The highest quality, obtained from the first cold pressing of the olives, with no chemicals or heat used. It has to meet strict chemical and sensory standards.

Refined Olive Oils

On the other end of the spectrum, avoid refined olive oils like the plague. These undergo intense processing, heat, and chemical treatments, effectively stripping them of their nutritional benefits and robust olive flavor.

Avoid any olive oil labeled as "olive oil" or "pure olive oil," as these are blends of refined olive oils, often with some virgin or extra virgin oil added back to improve flavor. They may also contain other refined vegetable oils, making them virtually indistinguishable from any other cheap, refined oil.

Besides watching out for refined olive oils, be wary of labels and claims that might mislead you into buying inferior products.

Less is Not More: Light or Extra Light Olive Oil

Avoid "light" or "extra light" olive oil, often marketed as lower in calories and fat. This doesn't mean they're made from the first cold pressing. Quite the contrary - they're usually refined with the olive oil flavor artificially added back, making them less flavorful and nutritious.

Country of Origin: More than a-label

Be cautious about olive oils claiming to be from a specific country, only to find they're not made from that country's olives. Some brands misleadingly use the name of the country where the oil was bottled, or merely stabilize their oil in that country. Always look for the certified Harvest Date and ensure it was processed within a few months of harvest.

Lackluster Producer Claims

Ignore grandiose, vague claims like "first-cold pressed," "cold-pressed," or "first-pressed." While these terms may imply the oil is unrefined, there's no legal definition, and it could still have been refined or mixed with other oils.

More Red Flags to Watch Out For

Avoid these additional pitfalls to make sure you're buying authentic, high-quality olive oil.

The Bitter Truth About Color

Despite popular belief, color doesn't indicate quality. Olive oil ranges from golden yellow to deep green, depending on the variety of olive and when it was harvested. Darker doesn't always mean better.

Fake News: The "Bottled in Italy" Myth

Italy is renowned for its olive oil, but when buying oil at the supermarket, Italian origins don't guarantee top-notch quality. "Bottled in Italy" only means the packaging was done there, not that the olives were grown, harvested, or milled Italian.

admirable but Not airtight: Olive Oil Awards

While olive oil competitions and awards are a great way for producers to showcase their craft, entries aren't necessarily blind-tasted or independently verified. Always check the technical report for chemical parameters and sensory evaluation to ensure the oil meets thenga.

With this knowledge, you're now armed to navigate the olive oil aisle with confidence. Embrace unrefined, cold-pressed extra virgin olive oil, and steer clear of misleading labels, refined oils, and other red flags. Your taste buds and your health will thank you.
