Dwarven stout (m) is a keg containing one to four pints of Dwarven stout (m). It's made by using a calquat keg with a finished barrel of ale after brewing Dwarven stout and randomly getting a mature batch. The brewing process makes 8 pints of ale, which is enough for two full kegs. The keg can be directly drunk and has the exact same effects as drinking a glass of Dwarven stout (m). Beer glasses can also be used on the keg, putting one of the pints into the glass. A glass of Dwarven stout (m) can't be put in back into the keg after coming out.
