"Let's hop into a time machine and go back to the England of yore!"
A small selection of readings in the original accent from a few important periods of English literary history. Well, and actually a bit earlier: all the way to Arthurian Britain, as well as we can guess at it.
But take heart: if you couldn't ask for the beer in Old Brythonic, ask for it in something like Latin. Pretty much any Romance language you know will have preserved a word for beer that Arthur's kindred would have learned to understand.
