Sam Adams beer boxes include a short and sweet story. You can't read it from the picture here, but underneath Boston Lager, it says, "Back in 1984, I dreamt of starting my own brewery. I found my great-great-grandfather's 1860 recipe in the attic and began brewing it in my kitchen. This is still the best beer I brew. I hope you will enjoy each sip."
There's a different story on each Sam Adams flavor - Dunkelweizen, Harvest Pumpkin Ale, Octoberfest, Winter Ale, Noble Pills, Holiday Porter, Chocolate Bock, etc. The Sam Adams website has more narratives. For example, a new episode is posted every couple of weeks documenting the current Sam Adams/Weihenstephan collaboration.
