one liqueur wine (aka liqueur wine or fortified wine) is a special type of wine with a very high alcohol content, usually between 14 and 23°. It can be obtained in two basic ways:

• By adding alcohol to the must before fermentation: In this case, alcohol is added to the wort before fermentation begins.
• By stopping the fermentation with the addition of alcohol: Here, fermentation is stopped by the addition of alcohol, resulting in a mutated wine.

Liquor wines keep well thanks to their alcohol content and, in the case of sweet liqueurs, also sugar. Some types of liqueur wines include:

• Liquor wine, liqueur wine or fortified wine: It is a generous sweet wine with a sugar content of more than 50 g/l.
• Sherry wine: Originally from the Jerez region in Spain, this wine is famous for its unique flavor and aging in oak barrels.
• Port wine: Coming from the Douro region in Portugal, Port wine is another example of a liqueur wine, with a sweet flavor and a high alcohol content.
• vermouth: This flavored wine is made with herbs and spices, and is often consumed as an aperitif.
