I'll copy my post from the Harpoon tour in Boston, went there on Saturday
Yesterday we did the Harpoon brewery tour up in Boston....my friend said it was 10x better than Sam Adams. Went over the grains and the process but since we don't get much of a Harpoon selection down here I most enjoyed the tasting portion. At the beginning of the tour they gave us some of the stardard IPA, then we had the IPA straight out of the filtration tank. This one was still a few days out from being a finished product, so it was a bit more cloudy and didn't have a very clean taste but it was still good, then when we got out of there we got the finished product again. Unfortunately they were getting a new kegging machine so the bottling stuff was under construction and they couldn't let us in there, but they comped the tours for the day (normally $5)
For the tasting they gave us a glass and gave us generous pours (I think only 2 oz is the legal limit in Massachusetts but they were probably giving us four) on whatever beers we wanted for about 20 minutes, no limit and their entire selection. I branched out and started with their Harpoon Dark, and dunkel-type that had a very nice balance of chocolate and malts and seemed to be a favorite with a lot of the workers/brewers. They also do a series where their workers are able to submit creations and the best gets 100 barrels produced, so I had that which was their 25th anniversary original IPA from one of the creators that was very much like the normal IPA but had a really awesome lemonish kick at the end. The only other one I got around to was the UFO White (Blue Moon but laughably better) and got a taste of another one from a friend, think it was the Belgian Pale Ale that was pretty good. I'd recommend it but drink faster than I did because last call was exactly one hour from the start.
