Etymology: "Casking" is simply the -ing form of "cask," so its story is really the story of the noun. "Cask" came into English from Middle French "casque," a word that also gave English "casque," the helmet, and it is a doublet of the Spanish and Portuguese "casco," meaning a helmet, skull, or hull of a ship. The shared sense is a hollow shell, which explains how a term for armour and a term for a barrel ended up as relatives. The barrel sense is the one that matters for the verb. Once "cask" meant a container for liquids, "to cask" came to mean putting a liquid into one for storage, and "casking" names that process. Ageing spirits and wine in wood is now the dominant context, so the verb is closely tied to maturation and the flavours that develop during it.
