Mead spans both geography, time and culture. It would be difficult to define every category in one place. In fact the best attempt we’ve come across is themead wikipedia article.

In this part of the world it is not uncommon for the word mead to conjure up in the mind images of nordic folklore. One can imagine burly warriors in a mead-place or mead-hall merry making with a king. Imagery that surely has been reinforced in popular stories of our time.
