Abstract
Process for producing wines with a high alcohol content, using 4 or 5 fermentation bioreactors, wherein the ferment is recovered, reactivated and recycled by separating the yeast-free wine from the ferment, yeast treatment with acid, separating the cells from the weak water and reactivating the cells by adding nutrients. The fermentation step takes place in an equipment that has a novel design, as well as the separation step.
