Filled Yellow Brewfest Stein

The can be filled at a Brewfest Festive Keg, becoming a Filled Yellow Brewfest Stein, and then can be used 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 2007, this item was a quest reward from
 * Did Someone Say "Souvenir?" (Alliance)
 * Did Someone Say "Souvenir?" (Horde)

Use
Equipping an empty Yellow Brewfest Stein, then using a Brewfest Festive Keg will convert the stein into a Filled Yellow 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 Yellow 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 buffs, 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 2007 Stein are different than the quotes for the 2008 Stein.

Alliance

 * Thunder 45 ( "Thunderbrew's got ya covered" )
 * Barleybrew Clear ( "Barleybrew filled, Brewfest approved" )

Horde

 * Small Step Brew ( "The path for good brew ends at Drohn's Distillery." )
 * Jungle River Water ( "T'chali's Voodoo Brew is 98% body part free." )

Both

 * Gordok Grog ( "It's not just ogre brew, it's Gordok brew." )

Historic note
Apparently, this aspect of the Brewfest has changed for 2008, or these statements were misleadingly worded:


 * "Fill at a beer barrel" - In 2008, the Brewfest Festive Kegs that you fill your stein at are different from all the other barrels. You can only fill at Brewfest Festive Kegs.


 * "There are several beer barrels at each beer garden (one beer garden at each major city)." - In 2008 there are celebrants outside the major cities, but only Orgrimmar and Iron Forge have the Brewfest Celebration Grounds, and only they have the Brewfest Festive Kegs where the mugs are filled.

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 Yellow 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 2007, so you'll only have one anyway.

Use as a weapon

 * This mug is a miscellaneous weapon, as is the.
 * It must be wielded to be filled and used, so presumably is miscellaneous so that any character can use it as a mug.
 * As this item is classed as a weapon, attempting to use when it is not equipped it will equip it.
 * Both the full and empty forms have the same low weapon stats.
 * Since they are miscellaneous type weapons, many class skills will not work with them.
 * On the other hand, they have no level requirement, and neither does the quest that awards the mug.
 * Literally any character can obtain and wield these in the current year.
 * Glowing effects from enchants do not work on Yellow Brewfest Stein.
 * If you have this mug from 2007 and acquire the 2008 mug, you can dual wield them (assuming you can dual wield).
 * This may cause difficulties with filling the mugs.
 * If you run into this, unwield one of them before you fill the other.
