To test olive oil purity, start with a fridge test: chill a small bottle in the fridge for 24 hours. Pure olive oil tends to solidify, while subpar oils remain liquid. Smell the oil; authentic olive oil has a fresh, grassy aroma, not rancid or musty. Use a taste test: true olive oil tastes fruity with a slightly spicy finish. For a precise assessment, consider laboratory testing to check chemical composition and ensure authenticity. These steps help verify quality, ensuring you enjoy genuine olive oil flavor and benefits.
