Olive oil quality begins in the country.
Olive oil quality begins in the country due to the combination of environmental factors (climate and soil), genetic factors (olive tree variety), and agronomical factors (farming techniques).
Olive trees grow slowly - the first fruits only appear five years after planting. At the age of twenty they reach full development and between 35 and 150 years they are at their most productive stage. After that, olive trees get old and yield becomes uneven.
