Didn’t they drink out of wine skins? Cheaper, more sturdy than glass.. and beer was drunk from wooden tankards, 4 pints in size unearthed, probably 2000 years ago in wales.
>When full, the tankard would have held nearly four pints of beer or cider. It was held in two hands and was probably passed around a group as a communal drinking vessel. //
Like a wassail cup or so.
