Cidre de Bretagne are ciders produced in the Brittany region in France, clear or muddy alcoholic beverages made by the fermentation process, with a foamy head and fine bubbles throughout the body. The ciders vary in color from yellow to brown, according to their geographical positions, so ciders from Ille-et-Vilaine, which are more acidic, have a lighter color, and ciders from Finistére have a darker color because of the bitter apples from the area.
