Uh, I hope Josh Boxer has done his homework here and had some tests done. I think it has been a practice of AB to brew a stronger beer and water it down for quite some time. The key is, the beer starts out stronger than the 5% ABV advertised on the bottle and then is blended down to the correct strength. I think this practice saves them tank space and allows them to brew more beer, saving them money.
Why do I suspect this guy got drunk one night, one of the AB Fairfield plant employees was at the same party, told him about this practice and, when he woke up the next day, he didn't quite remember it correctly?!?!
