Product title: Barbera Frantoia Sicilian Extra Virgin Olive Oil, 33.8-Ounce (Pack of 2)
Product description: Extra virgin olive oil Frantoia is produced from the olive trees planted in the western Central Hills of Sicily. Three varieties of olives: Nocellara, Cerasuola and Biancolilla are used for this oil. Handpicked from the trees, they are sent daily to the olive press, where they are carefully crushed by traditional granite grinders. A cold centrifuge system is used for extraction guaranteeing maximum hygiene. Tradition and advance technology are joined together in the production of this elegant full bodied gold green olive oil, with a rich aroma, delicate fruity flavour and a slight aftertaste of sweet almonds. In order to appreciate it at its best, we suggest using it raw on fish, fresh cheese, salad, vegetables and bread., Statements regarding dietary supplements have not been evaluated by the FDA and are not intended to diagnose, treat, cure, or prevent any disease or health condition.
