We have a nephew coming to visit that is a real beer hound. For those of you really into these things, which are the really essential boston area spots? and does Portsmouth NH have a particularly worthy craft beer scene/ worth the one hour trip time? I've also heard there were some good brewers in the Newburyport/merrimac area? And if you were doing a New Eng tour, what would be excellent locations? or if you could link me to a CH thread or an article.... much appreciated! Thx again.
