This extreme lithological complexity is reflected in an equally complex elevation pattern. In the outcrop areas of the more lithoid deposits (conglomerates, sandstones, marly limestones), the declivities are relatively higher, and the slopes are dissected by the hydrographic reticulum. Conversely, where clayey-marly-silty deposits prevail, slopes are undulating, irregular, gently inclined, and with significant geomorphological evidence of water and mass erosion (landslides). The prevailing soils are Calcisols (Haplic Calcisols), deep, marly, moderately fine-textured; Cambisols (Calcaric Cambisols), moderately deep, moderately fine-textured; Andosols (Vitric Andosols), deep, on ash fall deposits, moderately coarse-textured. The presence of Cambisols (Calcari-Vitric Cambisols) and Luvisols (Cutani-Vitric Luvisols), deep, on calcareous marls, mixed with ash and fall ash pumices, with a fine to moderately fine texture, is less frequent. The slopes of the areas under vines vary, predominantly (72% of the territory), from moderate (6-13%), strong (13-20%), and very strong (20-35%); a portion of the territory (11%) is characterised by gentle slopes (2-5%). Exposures are predominantly (77% of the territory) concentrated in the north-west and south-east. The bioclimate of the vineyard area, classified using Winkler Index, ranging between 1550 and 2152, with an average of 1958, is particularly well suited to the production of fine wines. A significant impact on the quality of the grapes and the resulting wines is exerted by the summer temperature ranges that characterise the hilly area where Taurasi is produced.
