We've spoken many times about the health benefits of extra-virgin olive oil (EVOO). But how do you choose a genuinely good one and keep it fresh? Why does this matter? Extra-virgin olive oil is an important part of the Mediterranean diet, which has been linked to a lower risk of heart disease and stroke. Choosing a good-quality olive oil and storing it properly can help preserve its flavour and the natural compounds that may provide health benefits. When buying olive oil, look for: • 🏷️ Extra virgin" on the label. Extra-virgin olive oil is made by pressing olives without using chemicals. This helps keep its natural flavour and nutrients. • 📅 A recent harvest date. Unlike wine, olive oil does not improve with age. Its flavour fades and its beneficial polyphenols (antioxidants) gradually break down. Look for "harvest date", "harvested" or "crop year", rather than relying only on the best-before date. • 🫙Dark glass or a tin. Light can gradually damage the oil and reduce some of its beneficial compounds. Dark glass and tins help protect the oil. • 🌍Clear information about its origin. Check where the olives were grown and where the oil was produced, not just where it was bottled. Some producers include a QR code that provides information about the oil's harvest date, origin, producer and, occasionally, laboratory results. This can improve traceability, although a QR code alone does not guarantee quality. • 📦 A practical container size. Choose an amount you can finish within a few months. A large container is not economical if the oil remains open and exposed to oxygen for too long. • 💧Filtered oil for longer storage. Unfiltered olive oil can be delicious when it is very fresh, but excess moisture and sediment may cause it to deteriorate more quickly. If you choose an unfiltered oil, use it promptly. Price and attractive packaging do not always guarantee quality. Words such as "pure" and "light" do not mean that the oil is fresher or healthier. "Light" refers to a milder flavour and colour, not fewer calories.
