Calvados is a distinguished apple brandy that originates from the Normandy region of France. Its history dates back to the 16th century, but it gained official recognition in the 19th century when the name 'Calvados' was attributed to apple brandy produced in certain areas of Normandy. The spirit's production involves fermenting apple cider into brandy, followed by a mandatory aging process in oak barrels. This method has been refined over centuries, contributing to Calvados's rich cultural and historical significance in French gastronomy and mixology.
