Basilicata is a predominantly mountainous and hilly region, with many areas suitable for viticulture and wine production, yet only 8% of its territory is flat. South of the volcanic area of Vulture begins the Apennine zone, while to the west stands the Maddalena mountain range, marginally affecting Basilicata, separated from the Vulture massif by the Melandro Valley and the Upper Agri Valley. The entire eastern side is hilly and subject to continuous changes due to the erosive phenomena of clay soils, creating deep grooves in the soil along the hillsides (calanchi) in the Lower Agri Valley and Matera area, with little or no vegetation. The flat areas are mainly in the Metapontine Plain, facing the Ionian Sea, formed from the accumulation of eroded material carried downstream by the rivers, which are abundant in the region. Some rivers, such as the Agri, Basento, Bradano, Cavone, and Sinni, originate and flow entirely within Basilicata, emptying into the Ionian Sea, while others, like the Noce, Ofanto, and some tributaries of the Sele, partially cross the region, flowing into the Tyrrhenian or Adriatic Seas.
The climate in Basilicata ranges from mild to continental, transitioning from the coastal areas to the mountainous inland. Precipitation is much more abundant in the mountains, while in the hilly and coastal areas, it is less widespread. Particularly, the Murge area experiences dry and very hot periods. The Metapontino area alternates mild and rainy winters with hot, dry, and fairly windy summers, ideal for the production of white grape varieties such as Greco and Malvasia, yielding medium-bodied wines with great aromatic consistency. The hilly area towards Matera, characterized by clay and sandy soils with marine sediments, cultivates Greco and Primitivo grapes, producing structured wines with great olfactory complexity. The alluvial and marine valley floor, with its fertile and deep soils, is ideal for cultivating Merlot, Cabernet Sauvignon, and Sangiovese. The Vulture area, in the northeastern part of the region, is particularly suited for growing Aglianico del Vulture. The vineyard soils near the extinct volcano are rich in potassium, giving the wines freshness, sapidity, and minerality. During the typically dry summers, the porosity of the tuff ensures adequate moisture for the vines, thanks to the water accumulated in the winter months. The more inland hilly area of Matera, with altitudes up to 300 meters, has less pronounced Mediterranean characteristics. The summers are still hot and dry, with significant temperature variations, favoring the cultivation of Primitivo and Sangiovese grape varieties.
