The importance of sub-regions Meteorological and geographical connections begin with high rainfall (1200mm per year, concentrated between October and April) and a severe maritime influence, along with the thread running through that are Vinho Verdeâs rivers. Sub-regions are demarcated by the rivers and thus the micro climates are created. Amarante, Ave, Basto, Baião, Cávado, Monção E Melgaço, Sousa, Lima and Paiva; these are the nine sub-regions, each their own entity, defined, delineated and organized by geography, geology, exposition, varietal and terroir. While the generalization of Vinho Verde soils are mainly attributed to granite and low depth, sandy or Franco-sandy, there are more multifarious compositions but all lean towards wines of moderate to especially high acidity, especially when the tenets of poorly phosphorous and of low fertility are involved. Vinho Verdeâs salinity and minerality is mainly derived from its granitic soils. In the sub-region of Lima, loureiro is the varietal darling. The most famous of Vinho Verde producers also look at alvarinho for solo measures but it is the northerly sub-region of Monçao e Melgaço along the Minho River where that most known VV variety receives the greatest attention. That is evident none more so than through the diverse verging on obsessive lenses of producers such as Soalheiro and Provam.
