Well, after some reasonably sound advice from some of the folks over at BeerAdvocate I decided to crack open one of the suspect bottles and see what was going on.
It was a bit of a gusher and my attempts to filter it through a paper towel -I was out of coffee filters- before pouring it into my glass were fruitless, so I just let it fly. It didn’t smell bad at all; smelled like I would expect a Belgian to smell so I figured why not. And yes it tasted like it too. Tasted pretty good actually, but in the end I had to dump it. No matter how good it tasted I couldn’t get past feeling chunks of stuff hitting my lips, even if those chunks were harmless bits of protein. Chunky peanut butter is fine; chunky beer… not so much
I’ll pick up some coffee filters and try the other bottle sometime since it’s gross, but safe. So kids, remember to actually look at your beer before you buy it.
