Never noticed. Probably have been too buzzed too. But Sixpoint renamed Bengali Tiger "Bengali?" When the **** did this happen and why? Hipsters. It likely occurred when they stopped selling four-packs in 16-oz. cans. They now sell Bengali for the same price but in a six-pack of 12-oz. cans.
It's actually a slightly better deal then (same price for 72oz instead of 64oz). That being said, it looks like it happened in April.
