To help you find a replacement for Pliny the Younger, head to the Monrovia location of 38 Degrees for their Triple IPA Fest on Saturday, February 25th. Starting at 11am.
Since PtY is limited by the brewery (until their new Windsor production facility could be utilized to make more), you have the enviable task of finding beers as good or better for your big hops, big ABV fix. They will have quite a few examples on tap and you get to use their fancy iPads to help you choose.
