I had a 4 pack of PM last month (2013 batch) and it was awesome. It held it's own in a blind tasting with BCBCS and KBS.
When not infected I'll say right now that I think I prefer it to both those beers. But the infection...oh god the horrible infection.....It made baby jesus cry. I'll pick up a single 4 pack and drink it quick, not gonna buy a case or so again, too much risk.
