Brewmaster

"Brewmaster" sounds like a nice title... ^.^

As it currently stands, players will not be able to complete this achievement (or the meta-acheivement What A Long, Strange Trip It's Been) until September 20th, 2009 at the earliest, when Brewfest 2009 begins. All new characters, including death knights, will be unable to complete this achievement until September 2010 at the earliest.

Update: Brew of the Year was removed as a requirement for this achievement in patch 3.1. Players can now complete the achievement in one year.

Although some people are saying you need 550 tokens for Brewmaster, this is not true.
In fact, you need only 350.

Disturbing the Peace, (http://www.wowhead.com/?achievement=293) requires you to have 3 Brewfest clothing items. To purchase all 3 it costs 350 tokens. To save yourself from building up another,un-needed , 200 tokens for the Brew of the Month Membership (http://www.wowhead.com/?achievement=2796) , simply return all 3 clothing items to the vendor for a refund after completeing the achievment, and then buy the Brew of the Month Membership form.
