A liquor (or liqueur) made by mixing or redistilling neutral spirits. Fruits, flowers, herbs, seeds, roots, plants or juices are used and a sweetening is added. Most cordials are sweet, colorful and highly concentrated. Many are made from secret recipes and processes.
A cordial is any invigorating and stimulating preparation; e.g. peppermint cordial. The term derives from obsolete medicinal usage, as various beverages were concocted which were believed to be beneficial to one's health, especially for the heart (cordialis, Latin). From the Renaissance onwards, cordials were usually based on alcohol in which certain herbs, spices or other ingredients were allowed to steep.
