This month's brew works a bit like last month's in that it uses a buff, and when the buff expires it triggers another effect. Drinking the brew will sometimes proc Gassy, and when Gassy expires (or you click it off), you belch. When you do that, anybody in front of you will be a little unhappy.
Can't say I'm a fan of the brew this time around, at least not as much as last month's Wild Winter Pilsner. It got a chuckle out of me, but I probably won't carry a stack around at all times like I did with the last one. Definitely does not topple BigRedPriestess.
