                Most of the Castelli Romani stand on the external ring of the 
                volcanic crater of the Colli Tuscolani, stretching over the Colli 
                Albani till Monte Artemisio (925 above sea-level) to reach the 
                Maschio Lariano (821 m above the sea-level) and then extending 
                northward on the Monte Salomone (773 m above the sea-level) to 
                meet again the Colli Tuscolani. The little internal ring is characterized 
                by Monte Cavo (949 m above the sea-level) and by Monte Faete (956 
                m above the sea-level). 
                 
                Coming from Rome visitors can observe Monte Cavo dominating the 
                area with its typical flat peak. 
                It seems to be the central volcano, but it was created by detritus 
                coming from the eruptions of the principal craters: i.e. the Lakes 
                of Albano and Nemi and those of Ariccia and Pavona, that have 
                been drained. 
                 
                All the grounds nearby have a volcanic origin, even if different 
                in lava consistency. The same origin characterizes the few alluvial 
                soils of this zone; thus they are very rich in potassium, an important 
                element to process sugars, and without calcium. Definitely the 
                good drainage of these soils is due to their layers. A main condition 
                however has to be accomplished, i.e. loose volcanic rocks on the 
                surface level or just a meter underground have to be brought to 
                the direct exposure of atmospheric agents, so that within two 
                years their deterioration will form a fertile ground. 
                 
                Average annual rainfalls range from 750 and 1,000 mms. on the 
                coastal zone, and reach 1,250 mms. on the hills, where viticulture 
                is of main interest. On the mountains the average amount of rain 
                falling during a year is of 1,500 mms. but these are forested. 
                Spring and autumn are the most rainy seasons, and therefore even 
                during summer grounds are prepared to receive rain in the depth.  
                 
                In the soils not very rich in humus is put manure through the 
                “sovescio” procedure, i.e. by planting during Spring 
                leguminous plants such as the “favino”, that can fix 
                the atmospheric nitrogen in their roots, and can produce an abundant 
                vegetation, which by decomposing fertilize the soil, increasing 
                the capacity to absorb humidity. 
                The DOC Wine “Castelli Romani” has been the last one 
                to be recognized. It has been added to the other DOC wines to 
                help many producers which have vineyard characterized by only 
                one type of vine, generally: spotted Malvasia, also named Malvasia 
                del Lazio or Greco. This aimed also to satisfy consumers different 
                exigencies and to control red wines production in those areas 
                where only the white one was already controlled. With the DOC 
                “Castelli Romani” are controlled not only red wines 
                but also new wines and rosé. 
                 
                Production territory: there are areas near to the Castelli Romani 
                ones, similar in environmental conditions, to expand the cultivation 
                of those producers already involved in the cultivation in the 
                areas controlled by the DOC. The producers in these surrounding 
                areas have the same oenological and agronomical culture of those 
                of the Castelli Romani; these areas thanks to their environmental 
                and climatic characteristics have been added to the DOC “Castelli 
                Romani”. 
                 
                Therefore, the territory characterized by the general denomination 
                “Castelli Romani”, consists also of the towns of Rocca 
                di Papa, and Rocca Priora, and Ciampino and Lariano which recently 
                have been divided from Marino and Velletri; Zagarolo and San Cesareo 
                which already formed the Zagarolo DOC; and Cori, Cisterna and 
                Aprilia, recently included thanks to their geographical and human 
                conditions. Cori and Aprilia are already characterized by a specific 
                DOC.
