Filtered or Unfiltered Olive Oil? Let’s Clear Things Up

Let’s clear up some myths, perceptions, and facts about the filtration of extra virgin olive oil.

🔍 What is unfiltered olive oil?

Unfiltered olive oil is oil that, after extraction, is not passed through a mechanical filtration process.

It typically looks cloudy or hazy, containing tiny traces of water and olive particles (like pulp or skin) in suspension.

Some producers let the oil settle naturally before bottling. In this case, it’s called “naturally clarified” or “partially decanted” oil.

🎯 Why some people love it

Artisanal look: Its cloudy appearance suggests rustic charm and freshness, often appealing in direct sales.
Cultural value: In some regions, cloudy oil is a local tradition and part of olive oil heritage.

⚠️ But it’s not always better

Less shelf-stable: The suspended particles can accelerate oxidation and fermentation, so unfiltered oil should be consumed relatively quickly for best quality.

Our tip? Always read the label, ask the producer for details, and store your olive oil properly—away from heat, light, and air.
