Apfelwein
Apfelwein , or Viez ( German: [fiːts], Moselfranken, Saarland, Trier; lit. 'vice') or Most ( German: [mɔst], Austria, Switzerland, South Germany; lit. 'must') are German words for cider. It is made from various kinds of sour tasting apples (such as "Bohnapfel"). It has an alcohol content of 4.8–7.0% and a tart, sour taste. Apfelwein is also regionally known as Ebbelwoi, Stöffsche, Apfelmost (apple must), Viez (from Latin vice, the second or substitute wine), and saurer Most (sour must, Süßmost or sweet must is essentially apple juice). Instead of the name Apfelwein, restaurants and smaller manufacturers may instead call the beverage Schoppen or Schoppe, which actually refers to the measure of the glass. In the Frankfurt area, berries from the service tree (Sorbus domestica) may be added in small quantities to increase astringency, in which case the specific type of Apfelwein is called Speierling. In modern times, the term Speierling is often also used to refer to any more sour variety of Apfelwein, even if it lacks any juice of the service tree.
