To begin, let's clarify something: there is no such style as a "Boston lager," This is part of Sam Adams' genius. By minting their own style, Boston Lager has now become its own thing. Perhaps this is how Newcastle Brown started. In any case, I guess you could call it accurate: the beer in question is brewed in Boston (or was, originally) and it's a lager. Perhaps due to its enigmatic designation, it has grown to be one of the best-selling craft beers on the market, and deservedly so.
The beer is crisp and dry to my palate. The hops--classic German noble varieties--are present but not forward, as in a pilsner. But, neither do they hang back as in a helles. The malting is clean and smooth, with just a hint of biscuit. Throughout a single sip, I find the beer dry--from the first notes, through the clean malt middle, and to the aromatic hoppy finish. It is the rare beer that pleases on a hot summer day as well as a cool autumn day (in fact, I think the style in which it has the most in common is Octoberfest), but Boston Lager does.
I rarely choose to buy a lager when any kind of ale is available, but Sam is an exception.
