As stated by others; Samuel Smith is the template beer...the classic. Some may be better but this one is still world class. Newcastle? Yeah...the first for many here but BMCish in comparison and hindsight. For American versions; Smutty Brown Dog & Avery Ellie's would be my favorites. Fat Squirrel is good but no longer year-around. I am hesitant to mention it for fear it gets too popular (I think it is their best seller now), but Tyranena's Rocky's Revenge is a great BA Brown.
