Fixed in many a schoolboy's memory is the fact that 15th Century George Duke of Clarence died in a butt of malmsey (aromatic grape) wine.
Take a handful of rose flowers, cloves, mace, nutmeg, all in a powder, quilt in a little bag and sprinkle with rose water, mixed with malmsey wine, and lay it in ye nod of ye neck.
In the scene as written, the murderers declare their intention to stab Clarence and then "throw him in the malmsey-butt in the next room," malmsey being a local beverage.
