In each treatment three repetitions were removed, starting from which it took place chemical, sensorial analysis and microbiological. Behaviors were observed quite varied in the texts of these constituent ones in the different times of it piles, the weight of 100 grains, humidity text, gross protein, gross fiber and gray fraction, they didn't have a defined behavior of variation, not increasing and nor decreasing with the time of piles, already the coloration index and activity of the polifenoloxidase, they decreased intensely and the text of compositions total fenolics showed an expressive increase (high adstringency). The cup test classified the coffes with 0, 1 and 3 days piled as drink it lasts, and the others 5 and 7 days as drunk riada. In the microbial composition, the fungus of the gender Aspergillus sp., Cladosporium sp. and Fusarium sp., increased in a significant way with the elevation in the time of it piles with the Penicilium sp, not presenting a defined tendency of variation
