Blackrock Lager is the June brew from the Brew of the Month Club.
All members of the Club get free sample of the brew in their in-game mail at start of June. Should you want more, your local Brew of the Month Club Brew Vendor sells it in stacks of six till the end of June.
On the first of June, members receive the following in game mail:
We've got a hot brew for you this month! All the way from Blackrock Mountain comes Blackrock Lager.
Remember, if you enjoyed this small sample, you can purchase more from our vendors.

Like any weak alcohol, this makes you slightly drunk. Also, like all Brew of the Month brews, drinking one of these will create a Empty Brew Bottle that can be targeted and thrown.
Special effect of this brew is chance to get "Internal Combustion: That last bit of brew is burning up your insides!" buff for 5 minutes, causing you to breathe red smoke, and removing the buff causes a massive burst of fire.
