La Fête des Buggeurs

Brewfest guide (Alliance perspective, Horde brewfest is near Orgrimmar with pretty much the same quests)
Now this is ram racing ... Almost (Ram Tutorial)
The first quest you will get is a tutorial about how to use a racing ram. You will need ram racing reins (from the apprentice next to the quest giver) to speed up with your mount, you can consider your speed like an energy bar that you fill everytime you use the reins. Basically, everytime you switch to trot, using the reins 4 times will get you to the "max" level of canter, using it a 5th time will change it to a galop, and smashing the button like mad will eventually exhaust your mount (when your Ram Fatigue debuff reaches 100) and get you stuck in place for 15 seconds. You can also pass near apples buckets to remove the ram fatigue debuff, there is one next to the signs after the bridge and another one behind the guy you need to see in Kharanos.

Daily Quest - There and Back Again
Reward : 15 tickets the first time, then 5 tickets for each keg delivered. (You can only do it once a day and you still have the 4 minutes limit, however you will get extra time everytime you deliver a keg and you can get 50 tickets each day with a decent route)
You need to get a keg from Flynn Firebrew in Kharanos, he's standing on a hill on the right of the road (next to the armory). Bring it back to the quest giver and do this 3 times, you can use the apples buckets to make it faster, but you can do without it.

Did Someone Say, "Souvenir?"
Reward : Yellow Brewfest Stein
Just give the voucher to Belibi Quickswitch in the Brewfest camp.

Daily quest - Bark for the Barleybrews! (Bugged for the moment)
You're supposed to go to 4 flags (see screenshot) in the capital and yell, I don't know if it's bugged or if I was too stupid to do it, but I couldn't complete it.
Reward : 50 Tickets

Daily quest - Bark for the Thunderbrews! (Bugged for the moment)
Reward : 50 Tickets
You're supposed to go to 4 flags (see screenshot) in the capital and yell, I don't know if it's bugged or if I was too stupid to do it, but I couldn't complete it.

Catch the Wild Wolpertinger!
Reward : Wolpertinger's Tankard (This pet is actually invisible to other players)
The point here is to ... drink, drink, and drink again. Buy wine from the wine vendor (or anything else) and drink until you feel completely smashed. (The emotes will appear in this order : You feel tipsy > You feel drunk > You feel completely smashed). When you're smashed, you will be able to see the Wolpertinger for about 10 seconds, then they will disappear and you will have to drink again to make them reappear. (This is how they look like when you're very drunk (or like this if you don't have full screen glow activated)

Pink Elekks on Parade (Not sure about this one, couldn't get it on some characters)
Reward : 75 Tickets
Visit the beer gardens in Stormwind, Darnassus, and the Exodar (they're small camp at the entrance of each city, see example) and zap 3 Elekks at each location. You have to be drunk as well for this quest.

Seek the Saboteurs
Every hour, Dark Iron dwarves will attack the brewfest camp (Screenshot #1, Screenshot #2, Screenshot #3), during the attack you can use Complimentary Brewfest Sampler in your inventory to throw them at the attackers, Belbi Quickswitch will give you a Brewfest Prize Ticket for each dwarf you knock down.
After the attack, you will be able to get a quest from plans on the ground. This quest requires you to go in Blackrock Depths (Grim Guzzler tavern) to find a guy. He roams in the room, behind the barrels most of the time, and will hide behind the plans seller (see screenshot) when you come too close. Just talk to him and you will get the [Dark iron Tankard]

Tickets rewards
You can buy tons of things with tickets. All these items (including mounts) will last after the events except the Belbi's Eyesight Enhancing Romance Goggles (Turns everyone into a gnome/orc depending on your side. 7 Days duration). The "Honorary Brewer" hand stamp will let you buy mounts from the apprentice (10 gold for the normal mount, 100 gold for the epic one). You need 600 tickets for the mounts, 100 for the goggles.
