Chartreuse, a liqueur, so called from having been made at the famous Carthusian monastery, La Grande Chartreuse, at Grenoble (see below). In consequence of the Associations Law, the Chartreux monks left France in 1904, and now continue the manufacture of this liqueur in Spain. There are two main varieties of Chartreuse, the green and the yellow. The green contains about 57, the yellow about 43% of alcohol. There are other differences due to the varying nature and quantity of the flavouring matters employed, but the secrets of manufacture are jealously guarded. The genuine liqueur is undoubtedly produced by means of a distillation process.
