In the German Palatinate common name (also Dubbeschoppe, Schoppenglas, Weinstange) for a glass to enjoy spritzer or wine. Usually it has a volume of 0.5 liters of a bottle, but also 0.25 or one liter. The glass widens at the bottom and at the top and has small indentations on the outside in which the fingertips are held, thus increasing the grip. According to tradition, the Dubbeglass was invented by butchers from the town of Bad Dürkheim, because at slaughtering festivals the rod glasses, which are often smooth in the Palatinate, slipped out of the greasy hand too easily. In terms of this function and composition, it is similar to the Mainz rod in the Palatinate. No depressions, but rather elevations have the same purpose as the glass known as ribbed glass in Hesse and the ancient knobbed glass.
The name is also derived from the indentations of the dubbe glass, because "Dubbe" means "swab". This quality is important because in the Palatinate such a glass is passed on in a round of wine according to an old custom and could easily slip out of hand when handed over to the next person. This convivial mood is illustrated by the beautiful saying: "De Dorscht, it's really fun, hoscht so e Pfälzer Dubbeglas! At the big wine festival "Dürkheimer Wurstmarkt" a "Dubbeglas order" with an annually changing motto is marketed.
