This is the bottom tier of beer festivals in Las Vegas. While festivals like Great Vegas Beer Festival, Brews Best, and Downtown Beer Festival pull premium vendors, breweries, and entertainment----Rockstar Beer Festival prides itself on mediocrity.
It's a overpriced frat party or Vegas Pool Club party. It's more of a party to be "seen" rather than drink craft beer at.
While they may pull a few local craft brewers, they really don't strive to pull anything else spectacular. Majority of the beers are your macro micros. The beer vendors in town such as Johnson Brothers, Southern, Nevada Beverage, and Bonanza tend to bring out the bottom of their portfolios. When you go to other festivals in Las Vegas, these vendors bring out beers you haven't heard of nor tasted. When you go to Rockstar Beer Festival (or any of the similar beer tastings the promoter does), you get Shocktop and Blue Moon!!!
The venue also is pretty bad as its too small. You would think with as few beer tents that they have that there would be plenty of room but there really isn't.
