Conteúdo: 	The viticulture in the semi-arid region, especially at the São Francisco Valley, Brazil, stands out on the national scene with high yields and high quality of the produced grapes, mainly regarding the sugar content. This fact is due to soil and climatic conditions of the region and the availability of water resources that favors the vine production all over the year. The accumulation of sugar in the grapes is essential for winemaking process, since it is necessary for alcohol production by yeasts, which contributes to wine aroma and taste. The aim of this study was to evaluate the fructose content on Syrah grapes during maturation, according to potassium and nitrogen fertilization on vines. At Embrapa Semi-arid experimental field, in Petrolina, PE, Brazil, Syrah vines, in  four blocks and drafted on Paulsen 1103 rootstock, fertilized with 0 (control - Treatment 1) or with 120 kg ha-1 of nitrogen, 120 kg ha-1 of K2O, as potassium nitrate and urea (Treatment 2) were evaluated from 105 days after pruning and at five stages (points) before harvest, according to the fructose accumulation of the fruit, collecting 50 berries per each treatment and evaluation time.
