Dire Brew is an alcoholic drink that can be obtained by looting a Mug of Dire Brew, or speaking to Dark Iron Brewer in the Grim Guzzler in Blackrock Depths. Using the item turns you into a Dark Iron dwarf for 1 hour and makes you drunk too. Of course after speaking with Dark Iron Brewer several times to get him to drop his Dark Iron cup, you are very drunk already.
As of patch 4.0, the Dark Iron Brewer appears to be bugged and speaking to him will no longer spawn the Dire Brew mug. It is a known glitch, however, so this may be fixed in the future.
- Patch 2.4.3 (2008-07-15): Added.
