Amontillado

Shortly before her death, Winifred Gillyflower offered the Eleventh Doctor a glass of Amontillado. (TV: The Crimson Horror)

Behind the scenes
Unremarked in the episode is any real notion of the fact that Amontillado is a type of sherry, made in the Montilla region of Spain.

This drink is known around the world thanks to the Edgar Allan Poe's short story, "The Cask of Amontillado".
