Bitter Rivals

Objectives
In the basement of the Thunderbrew Distillery in Kharanos, replace a barrel of Thunder Ale with a Barrel of Barleybrew Scalder.
 * Barrel of Barleybrew Scalder (Provided)

Description
I have to admit, those Thunderbrews make some good drinks. But they need to learn that theirs isn't the only decent brew! Maybe you can help me teach them that lesson...

Here, take this barrel of Barleybrew Scalder. Sneak into the basement of the Thunderbrew Distillery in Kharanos and switch it with one of their barrels of Thunder Ale. Then we'll see how their patrons like my brew over theirs!

And if the barrels are guarded, then you might have to distract the guard...

Rewards
You will gain:
 * 140 XP (or at level 70)
 * 25 reputation with Gnomeregan Exiles
 * 25 reputation with Ironforge

Progress
The date on this barrel shows that it'll soon be tapped.

Completion
You quickly place Marleth's barrel of Barleybrew Scalder among the Thunderbrew barrels.

Progression

 * 1) Bitter Rivals
 * 2) Return to Marleth
