Brewtopia Great World Beer Festival is coming to the Javits Center Friday and Saturday, and much as we’d like to pretend that it will be a Daytona-esque festival of frothy celebration — a “beerchanalia,” if you will — the truth is that it’s primarily aimed at beer snobs. But so what? No one who loves beer should turn down the chance, for $60, to drink all they want of hundreds of different brews, many of which are difficult to find in New York.
