Bummer. I always enjoyed Summerfest. Maybe they will bring it back in the future.
It's odd that this "session IPA" has both less alcohol and lower IBUs than their APA (which by the way is almost the only domestic beer I ever purchase). I guess the counterargument would be that it has, supposedly, hop flavor and aroma that is more on par with an IPA.
I do enjoy their Hazy Little Thing IPA, though it does sometimes cross over into that sweaty gym sock flavor.
