The State of Rio Grande do Sul is the first Brazilian grape producer of quality wines. Besides the Serra Gaúcha, the most important wine producing region of this state, new regions are being developed: Campanha, Serra do Sudeste and Campos de Cima da Serra. To know the characteristics and the variabilities of the natural factors is fundamental for the quality wines viticultural zoning. The objective of the work was to define zones in the State of Rio Grande do Sul according to the climatic conditions to produce quality grapes for the existing viticultural regions and for those that present potential for this activity. This work presents the thermal characterization, through the Heliothermal Index (HI), using data from 32 weather stations between 1961 and 1990. The multiple regression analysis generated an algorithm that estimates the HI value for the State of Rio Grande do Sul based on the independent variables altitude, latitude, longitude and the distance from the coast. A map with the six great thermal zones for wine production was elaborated using the geographic distribution of HI in the State of Rio Grande do Sul.
