I don't think it qualifies as craft brew, but the Amsterdam Maximator is by far the worst beer I've ever had. Whoever brewed this crap deserves to have their ass kicked.
Somehow, this stuff made me immediately hungover, completely bypassing the buzzed and drunk part. Each sip gave me an increasingly bad headache and upset stomach. Amazing, really.
Here are some comments about it on beer advocate:
"Like Satan's own urine... the taste was something akin to beer spilled into mop water, with a healthy dose of rubbing alcohol thrown in."
"This stuff tastes like my mouth after I used to wake up from college benders when I forgot to brush my teeth. Alcohol, slightly sweet grainy flavor, cheap hooch, aftertaste of nail polish remover and a touch of hops."
"Smell is repulsive. Honestly the homeless people I've seen drinking this crap could've pissed back into the can and barely told a difference.
Taste is miserable at best, downright offensive at worst"
