An ["Honorary Brewer" Hand Stamp] can be purchased from Belbi Quikswitch in Dun Morogh or Blix Fixwidget in Durotar for 600 , which allows you to buy a [Brewfest Ram] (normal) or [Swift Brewfest Ram] (epic). This mount is rideable by all races and factions, including tauren.

The hand stamp starts a quest which allows you to purchase rams from the festival's Ram Racing Apprentice and cost 10  for a normal mount and 100  for an epic.
