In the German federal state of Hessen, a term commonly used in the Frankfurt area (also cider or pint glass) for a glass for drinking cider, which is traditionally poured from the stoneware jugs known as Bembel. There are different sizes, which are called 4er-, 8er-, 12er- or 24er-Bembels according to their volume, measured by the number of ribbed glasses. The name of the glass is derived from the diamond-shaped, raised grid-like structure. This serves as a "gripping aid" for the greasy fingers caused by eating hearty food without cutlery. A further advantage is that the prism-like texture also lends shine to cloudy, unfiltered liquids. To protect the contents from dirt or insects, there is the "shopping-lid". Traditionally, this is a painted lid, usually made of wood, which is placed on the glass between drinking.
