A barrel of monkeys is, no doubt, very entertaining, yet for many adults, a barrel of expertly crafted ale is even better. That’s why, in addition to the regular tour at Samuel Adams Brewery, there are other opportunities for aficionados to take a peek behind the scenes at this beloved Boston institution. Four days a week, the Beyond the Brewhouse Experience offers a look at the facility’s Barrel Room along with an exclusive tasting, while on Fridays and Saturdays the Bier Keller Barrel Aged Experience (pictured) gives visitors the chance to sample more wood-aged goodness in another barrel-bedecked sanctuary along with some local cheese. While you’re there, be sure to take home a souvenir—liquid or otherwise—at the gift shop or tap room, which pours “crowlers” (32 ounce aluminum cans) of some exclusive, brewery-only styles.
