ZONEAMENTO GEOVITÍCOLA DE UVAS FINAS PARA A REGIÃO DO DISTRITO FEDERAL, BRASIL

Abstract

The Federal District presents its entire territory in the Cerrado Biome at an average altitude of more than 1000 m and an ideal temperature range for growing fine grapes in some months of the year. This fact, associated with public-private investment, launched in 2024 the “Wine Route or Grape Route” in the Federal District and Surrounding Region. Given this context, the objective of this work was to characterize the climatic potential of this region for the production of wine grapes, using the Geoviticultural Multicriteria Climatic Classification System, based on geoviticultural indices: Heliothermal Index (HI); Night Cold Index (IF) and Drought Index (IS). The data were obtained from an automatic meteorological station belonging to the National Institute of Meteorology (INMET) located in the Federal District over a series of 10 years (2015 to 2024).To obtain the climatic indices and their respective classes, the data were separated into two periods: “PF” formation pruning (Sep/Feb) and “PP” production pruning (Feb-Jul). The results obtained for the periods evaluated were: PF (Sep-Feb) - IH+3; IF-1; IS-2 and PP (Feb-Jul) - IH+2; IF+2 and IS+1. The indices for the grape harvest period were favorable for greater fixation of sugars and pigments. The Federal District presented geoviticultural indexes equivalent to countries with a tradition in wine production both in the Southern Hemisphere and in Europe.
