Primary fermentation is the starting point for each Champagne’s individual style and future sensory properties to develop. As during the pressing stage, the juices are separated during fermentation: by cru, fraction (taille or cuvée), grape variety and year. Primary (alcoholic) fermentation can be carried out in oak, but usually takes place in stainless steel vats. Depending on the type of wine they wish to make, they may choose to carry this stage out fully or only partially, or prefer to avoid it altogether. In either case, the fermentation is eventually dominated by the yeast Saccharomyces. Autochthonous or native fermentations are conducted by the microbiota present on the grapes and in the winery. The first is a necessary step in the Champagne production process, while the second is optional, and entirely up to each winegrower. With respect to the primary fermentation, there are two classes of processes: inoculated and autochthonous. Two stages are distinguished: alcoholic and malolactic fermentation. Many smaller wineries ferment all of their wines with only one or two types of yeast. The grape juice now goes through different fermentation stages. A few wineries use a different type of yeast for each wine produced. Several stages which bring out a whole bouquet of aromasĪfter clarification, the juices are all ready for fermentation. ![]()
