Mistelle (Italian: mistella; French: mistelle; Spanish, Portuguese, Galician and Catalan: mistela, from Latin mixtella/mixtvm "mix") is sometimes used as an ingredient in fortified wines, particularly Vermouth, Marsala and Sherry, though it is used mainly as a base for apéritifs such as the French Pineau des Charentes. It is produced by adding alcohol to non-fermented or partially fermented grape juice. The addition of alcohol stops the fermentation and, as a consequence Mistelle is sweeter than fully fermented grape juice in which the sugars turn to alcohol.
