Beer Summit
The real Beer Summit is a beer sampling event that has been taking place in Boston since 1999. There are now 3-4 events per year, seasonally- including winter, spring, and fall shows (they take the summer off).

These events (except the OctoberFest) have 60+ brewers represented and 250+ beers. More info@BeerSummit.com
I've been going to the Beer Summit for years, it's about time the rest of the world caught on.
