I've had it three times. The first time was the week it was tapped in BR. I don't think they would have sent an old keg?
I haven't had Mechahopzilla since late January. I just have no desire. It's big and just too bitter, without the aroma and flavor that I like in a DIPA. The one time I had it at the brewery it was much better, but I've yet to see that duplicated in a retail setting. I'm sure I'll grab a 4 pack when cans come out to try it again, but like someone else said, I'd much rather Timber Beast.
