Soil and climate effects on winter wine produced under the tropical environmental conditions of southeastern Brazil

Southeastern Brazil is an emergent region in terms of the production high-quality fine wines. To contribute to typicity assessment, soils (morphology, mineralogy, chemical and physical analyses), parent material (geologic maps portable X-ray fluorescence spectrometry) climate (temperature precipitation) were characterized seven vineyards located state Minas Gerais São Paulo, Brazil, by carrying out state-of-the-art terroir analysis assessing environmental variations study sites. A soil profile was described sampled central part each vineyard. Principal Component Analysis (PCA) biplots used analyze relationships between these factors composition wines (2016, 2017 2018 harvests) produced from Syrah commercial different municipalities Três Corações (TC), Cordislândia (COR), Andradas (AND), Sebastião do Paraíso (SSP), Pontas (TP), Espírito Santo Pinhal (PIN) Itobí (ITO). The grouped according characteristics. Group composed COR, AND PIN vineyards, which exhibited highest correlation with Al3+ content accumulated rainfall. group’s had lowest ash alkalinity, total polyphenol index (TPI) pH values fixed acidity. B consisted TP TC organic matter boron contents thermal amplitude similar (15.4 °C 15.2 TP); their showed average composition. C comprised ITO alone, shallowest least developed soils. Its wine flavonol high dry extract, color intensity, TPI, alcohol sugar values. D contained SSP vineyard, subsurface horizons correlated pH. Late harvest this vineyard caused most dehydration grapes consequent concentration compounds (human effect on terroir). information adds substantial value under tropical conditions southeastern for such studies are very rare. By characterizing natural (soil, climate) human (vineyard management characteristics) related terroir, can also provide historical about (the factors). In addition, its results be guide producers choice cultivation sites preference
