I have a lb of aromatic malt but haven't tried it yet. It's probably not the best malt for summer beers but maybe I'll sneak some into an APA.
Watermelon juice beers are a recent fad. The only one I've tried is "Hell or Highwater" by 21st Amendment and you can taste the watermelon. While I'm glad I tried it, I don't think I'd buy a six pick. It might be best served very cold after mowing the lawn.
