A fun tour, and definitely worth the visit if you are in Boston. Not the easiest brewery to find but not super difficult. For the price you paid you got a tour, three samples and you got to keep the sample glass. The tour guide walked you through the process of brewing, the history of the company and he gave some interesting local information. If I remember correctly the three samples I got were Boston Lager, one of their seasonal beers, and then an experimental beer which had not been released. And the cost you paid for the tour was actually a donation to a local charity, so that was kind of cool.
This was a fun brewery tour, which is what I'd expect from a company like Sam Adams. The guys running the tour were really into what they were doing, and were excited by the beer they were making. Sam Adams doesn't make my favorite beers, but I have a lot of respect for them for being a driving force behind the current rise in microbreweries today.
The tour ended with a few samples - a seasonal, a Sam Adams staple (Boston Lager, I think), and an experimental brew. It turns out that people at the company are allowed to try their own recipes in small batches, and then they give some of it out to tours. Seems like a great idea to me...
Definetly worth the trip when in Boston. By far the best tour I have ever been on. The staff loves there job, or mabey the beer they drink all day while giving tours. Parking kind of sucks so take a cab or public trans. This is acctually the plant where they try out new beers. Tours keep the groups interest. In the end you get a free 7oz glass and go into a small beer hall to sample 4 different beers and learn how to taste them. Afterwards go outside and wait for the party trolley which is free to take you to Doyles to get a free Sam Adams glass. The trolley is a awesome ride as well.
