From October to late November, the cider apple crop is gathered and stored in a dry place. When ripe, the fruit is crushed, then the pulp is pressed to obtain the must, which must have a minimum natural sugar content of 108 g per litre at the time of mutage for Pommeau de Normandie, and 123g per litre for Pommeau de Bretagne and Pommeau du Maine.
Until February 15th of the year following the start of the harvest, the Pommeau is produced by mutage of the pomace respectively with one of the three Calvados appellations, a Fine Bretagne or a Fine du Maine. which have matured for at least a year in oak casks after distillation and contained at least 65% alcohol by volume.
The mutage is completed in one operation respecting the proportions of roughly 3/4 pomace and 1/4 brandy. The two ingredients should be mixed well during the first few weeks.
The strength must reach somewhere between 15% and 20% alcohol by volume.
