Arguably, the problem with BREW versus SAM is that Samuel Adams Lager is the perfect "beer with training wheels" for people moving away from Budweiser and Coors Light. I personally dislike its bland, malty taste, but I can see how it is a good first step away from mass-market crud. BREW isn't Stone or Lagunitas, but it it makes stuff a little more challenging than SAM.
However, what might be instructive and scary is that SAM's p/e is about 45. Following that line, BREW should be at about $5.50.
