How can I be sure about the quality of olive oil I’m serving to guests?

Take the time to learn about olive oil grades and qualities. Learn to recognize rancidity. Ask questions when making buying decisions. Make sure your olive oil is not more than two years old, and taste-test it straight before cooking and serving it to customers. Several organizations offer quality certifications and quality testing.
