Contrary to widespread belief, the appearance of the Tuscan hillsides, so densely-planted with olive groves, is fairly recent. In most cases it dates only to the latter half of the 19th century. The final centuries of medieval times saw the first significant increase in olive growing which was encouraged and protected by the laws regulations contained in city statutes and established by rural communities. In the following centuries the olive then spread to a large part of the region. The impulse that landowners gave to the spread of the olive tree derived from their own desire not only to use but also to sell the product and this situation lasted until modern times.
Tuscan olive growing spread rapidly between the first al of the 19th an mid 20th centuries. Trees were planted abundantly in the traditional areas and also in other parts of the region where they previsiusly unkown or scarce. However, one cannot generalise when talking of Tuscan olive oil. Tuscany has, in fact, a whole variety of oils with different features and qualities. Each area of Tuscany has its own oil with its own fragrance, green and rich in colour and, above all, in flavour.
