A system of cultivation already used in ancient times by the Greeks and Romans, in which the vines grow on or between trees (alberata = small trees). Small-growing or annually pruned mulberry trees, chestnuts, maples, poplars or elms serve as support. Two to four vines were planted for each tree. Often this was used in combination with arable crops. In extreme cases, the vines are grown up to ten metres high. In this case, the relatively laborious harvest has to be done by means of ladders. To some extent, this system is still used in Italy today. There are local variants in the regions of Emilia-Romagna, Tuscany and Veneto. In Campania, this traditional form is permitted under the DOC regulations for Aversa or is pushed as a cultural heritage. The ladders here are called "Scale Napoletane".

I have great respect for the scope and quality of the wein.plus encyclopaedia. It is a unique place to go for crisp, sound information on terms from the world of wine.
