I believe Vikings drank Mead as their common alcoholic drink. If that is not right it doesn't really matter. Just replace Mead with whatever is right (beer, wine ...).
The question is what material did they use for their mugs to drink this drink out of? Perhaps it might be clay, wood or horn?
Note: I need the mug commonly used while partying or just sitting together on a table. If for example the "wilderness-mug" is different, it would be nice to know but it's not necessarily object of this question.
