The cultivation system, the cultivars, the crop conditions and post harvest, can effect the conservation and quality of the grapes. This work aimed the evaluation of the affect of the time of storage (0, 7, 14, 21, 28 and 35 days) and the storage temperature (1, 14 and 24ºC) in the quality of the grape "Niágara Rosada" pots harvest cultivated in the organic system. The limiting point for the storage was the high number of free berries observed, however the grapes still have quality for consumption, because observing without modification in the tenor of total soluble, the total titratable acidity and pH. Among the chemical assay, the determination of the tenor of total soluble solids, the total titratable acidity and the vitamin tenor C were the only ones which presented a decrease accentuated for the fruits stored at 24ºC, in a lower period of storage. The fruits stored at 14ºC up to 28 days did not show higher changes in their chemical characteristics and the grapes still have consumption quality and also for use in food industry. The best temperature of storage was 1ºC when grapes achieved 35 days with good quality.
