The recirculation of vinasse is an alternative process that is applied in different parts of the world. With its recirculation to the process, bearing in mind the percentage of vinasse that is possible to recirculate to maintain a proper operation in the fermentation stage and not affect its yield, is achieved savings of water to dilute the honey and the environmental impact that has the same is reduced. To determine the composition of the mixture water-vinasse-flemaza that guarantees the best yields in the fermentation stage, it was carried out an experimental design of mixtures of simple grid type and the models of the impact of the composition of the mixture in the fermentation yield and alcoholic percent were obtained. Of the obtained results conclusions and recommendations are extracted to extend this work to industrial scale.
