Filled Green Brewfest Stein < onlyinclude > < / onlyinclude > The can be filled at a Brewfest Festive Keg , becoming a Filled Green Brewfest Stein , and then can be use d to drink the brew . Filling , hence drinking , is free , and the brews are both alcoholic ( inebriating ) and provide mana restoration and a well fed buff . Source . During Brewfest 2009 , the Green Brewfest Stein was a quest reward from : Use . Equip ping an empty Green Brewfest Stein , then using a Brewfest Festive Keg will convert the stein into a Filled Green Brewfest Stein , containing a one charge sample of the beer from the barrel . The filled stein can then be used , drinking from it , which converts the stein back to an empty Green Brewfest Stein . The imbiber get the effects of the particular beer that was sampled . The full or empty stein must be equipped to be used . Varieties . Each of the three Brewfest Festive Kegs contains a different sample brew , so , depending on what barrel the owner fills their stein at , their Brewfest Stein will have a different sample of brew . Each full stein with a different brew is a different item , as is the empty mug . There are two icons , one for the empty stein and one for the full steins . Each Brewfest Festive Keg is near to one of the brew vendor tents . Each brewer vends three different strengths of brew , but the breweries specialize in a low , medium , or high strength range of brews . Stronger brews are higher level , restore more mana , have stronger buff s , and have a higher character level requirement to use . Each of three brews available from the Festive Kegs are the same as one of the three brews being vended by the brewer nearest that keg . The Alliance and Horde brews are different brews but have equivalent effects . The Barleybrew dwarves ' and Drohn ' s orcs ' brews are the weak , low level range . The sample nearest them is the level one sample , the weakest at the Brewfest , and can be sampled by all attendees . Thunderbrew dwarves and T ' chali ' s trolls have mid - range brews . The Gordok Ogres are shared by both factions , and have the strongest , highest level brews . Note : The Festive Kegs are neutral and inanimate . You should be able to use the opposing faction ' s Festive Kegs , if you can get to them . You can fill your mug with any of the three brews . The only way to empty your mug is to drink it ( use it ) . Drinking from your stein and refilling at a different Brewfest Festive Keg switches between brews . Anyone can fill their stein from any of the kegs . Since each beer has a minimum level associated with it , but the stein does not , you can drink a brew from your mug that has a higher level requirement than you are , but you will not get the buff . Instead you get a brief " Can ' t Hold Your Brew " debuff with a ' getting sick ' graphic and a message warning you not to drink the big kids ' drink . Note that the Alliance / Horde brews may be available in neutral cities as well . Quotes . This is the flavor text for each brew . Note that the quotes for the 2009 Stein are the same as the quotes for the 2008 Stein . Notes . Dark Iron Dwarf invasion . You fill at the same Brewfest Festive Kegs that the Dark Iron Dwarves attack when they invade . If the Dark Iron Dwarves succeed in destroying a Brewfest Festive Keg , you will be unable to fill your mug from that keg until it respawns . The destroyed keg will get a destroyed graphic with a caved in front , then disappear as the Dark Iron Dwarves depart . Uniqueness . The Green Brewfest Stein is unique . Since the empty and filled forms are different , uniqueness might not apply , but the mug is soulbound and you only get the quest once in 2009 , so you ' ll only have one anyway . Use as a weapon . See Foodfight Disenchantment . According to Blizzard ' s " The Armory " , ( see external links , below ) , any of the six Blue Brewfest Stein items can be disenchanted , yielding a . However tests say that it can not be disenchanted at all .
