I've tried so many different Sam Adams varieties, and they all kind of taste similar to me... probably due to the fact the the underlying hops they use are the same.
I guess if I want that typical Sam Adams taste, I will get their original Boston Lager. Otherwise, if I want an Oktoberfest, Pilsner, Dunkel, or White Ale... I typically enjoy some other brands that do not have that same underlying SA hop taste.
