With rising prices, olive oil is becoming a more considered purchase, with even routine supermarket shopping feeling like a small investment. As a result, choosing the best supermarket olive oil has become a challenge. Are premium brands truly better, or can supermarket own-label products offer the same quality and flavor for less? This guide explores the top options available in 2026, based on taste tests and evaluations. Extra virgin olive oil (EVOO), the highest quality olive oil, is made by cold-pressing olives at low temperatures, preserving its natural flavors and nutrients. These flavors can vary based on the olive variety, region, and harvest conditions, much like wine, which means one bottle might be buttery and mellow, while another could have a sharp, peppery finish. Beyond flavor, EVOO is rich in heart-healthy monounsaturated fats and antioxidants, making it both nutritious and versatile in the kitchen. After testing 15 different supermarket olive oils, three stood out as the best buys. **Exceptional by Asda Greek Koroneiki extra virgin olive oil** was the top choice, praised for its rich, balanced flavor with a slight peppery finish.
