Surprisingly, only 2% of Italian Olive oil is produced in Umbria. The climate is moderately mild for central Italy, fairly windy and quite damp thanks to nearby Lake Trasimeno. This part of the world is beautifully verdant. The Viola family have been crafting olive oil for 150 years and built their first mill in 1917 in S. Eraclio. The terrain is poor, chalky and very stony with steep slopes reaching up to 500m above sea level – it is not easy land to farm. They harvest only green olives to ensure a greater concentration of flavour and higher polyphenolic concentration.
