(m) is a suffix that denotes a particular ale is mature, meaning it has a stronger effect than the non-mature ale. In this context, it may also apply to the ale in a calquat keg, in which case it will be appended by a number 1–4 to denote the remaining amount left. It may also be used in various contexts to denote something is only available to Members.
