Resumo: Fine wine production in Brazil was historica11y established in the extreme South of the country, in temperate climate. More recently, new producer regions appeared in South, Southeast and Northeast of the country, including subtropical and tropical type of climate in the production scenario. This work had the goal to characterize the Brazilian climate diversity related to viticulture potential, in a11types of climates. The methodology used climatic database for a11country - series 1961-1990. Many climatic variables and viticultural climatic indices were mapped in GIS at the whole Brazil: viticultural climatic indices of the Geoviticulture MCC System, Thermal lndex of Winkler, Zuluaga lndex, among others. The Frost Risk was used to separate zones of the country with viticultural potential to produce only one vegetative cycle/harvest per year, from the others, with potential to have more than one cycle and, in particular cases, more than one harvest per year. In this case, the viticultural indices were calculated for two periods: spring-summer and autumn-winter periods of the year. The results identified the climatic regions of Brazil with no potential for viticulture. Also, the results identified the regions with viticultural potential in different types of climates, with the characterization of the classes of viticultural climate for different indices. This climatic zoning wi11be used as a baseline for estimating, in a medium and long-term, the impact of different scenarios of Climate Change in the climatic potential of current fine wine producer regions and also to prospect potential climates for quality wine production in the future.
