In the spirit of learning from the best, I attended an Olive Oil masterclass with Anna Cane, Chief Quality and R&D Officer - Deoleo S.A., the world's biggest producer of olive oil. As the 'Godmother' of Olive oil, she has more than 50 award-winning blends under her belt, 31 years in the food industry, five accreditations for Olive oil, and has been a Professional Olive Oil Taster since 1991, under the Italian National Olive Oil Tasters' Organization and Qualified Panel Leader under International Olive Oil Council (IOOC) since 1999. Sitting in a 250-year-old traditional farmhouse in the olive grove-speckled hills of rural Tuscany, the scene was set for a food lesson that was delicious – yet far more detailed than initially thought. Here are my hand-picked highlights of the four-hour course.
