On a mission to make a better, more flavorful American beer, Jim Koch created Samuel Adams Boston Lager in the mid-80's using his great-great grandfather’s recipe. Today, the small craft brewery makes more than 30 different beer styles. A tour of the Samuel Adams Boston brewery offers a glimpse at the entire brewing process while providing a complete history of the company. Of-age tour goers even get to sample a few of their award-winning beers. Tours depart every 45 minutes and last about an hour, and while the tour is free, a voluntary $2 donation per person is suggested.
