S.  aAgroclimatic zoning for winemaking grape production in the State of Paran??.h[electronic resource]  c2018  aParan?? is the fourth largest grape producing state in Brazil and the cultivation of  Vitis vinifera  L. cultivars for winemaking is  expanding is several regions of the state. The objective of this work was to characterize the potential of wine grape production based on the G??oviticulture Multicriteria Climatic Classification System for Paran??. A 30-year database constituted of 21 IAPAR (Agronomic Institute of Paran??) meteorological stations and 455 rainfall stations from Instituto das ??guas do Paran?? (Paran??  State Water Institute) generated the following climatic indexes: dryness index (DI), heliothermal index (HI) and cool night index (CI) for the periods of October to March and April to September. According to the results, the viticultural climate of some regions in the state of Paran?? belongs to the climatic groups where are found several traditional wine-producing regions in the world, showing potential for the expansion of winemaking in the state. Viticultural climate, associated with latitude in Paran?? and with thermal conditions for vine growing cycle all over the year, make production displacement possible in the West, North and Northeastern regions and the production of the best quality grapes for winemaking in the fall and winter period, due to the most favorable cold night index and the lowest rainfall volume. In the coldest regions of the state (Center, South and East), it is only possible to have one production cycle, since the risk of frosts prevents the explo ration of grapes in different periods.  aClimatic zoning  afine wine  aG??oviticulture MCC system  aquality  aVitis vinifera L1 aROBERTO, S.
