In the local vocabulary "neccio" is the word for chestnuts, going back centuries. The cultivation of chestnuts trees for their nuts goes back to around 1000 CE when a population increase led the inhabitants of this area to plant thousands of the trees in vast areas of unused land. In the area around Garfagnana a cultivar was created which is especially suited to the production of flour and chestnuts soon became the principal source of sustenance for the population.
The drying of the chestnuts is historically done in structures created for the purpose where the chestnuts are dried above a low fire without a flame, the rising smoke slowly drying the nuts over about 40 days until their ready for shelling and grinding. Since the 1950s there have been more than 7000 drying structuresand about 250 mills.
