Treehouse and Trillium are definitely the most hyped. Nightshift to be added to that list soon.
To say those two breweries make the 12 best beers in MA is beyond ridiculous.
They are fine breweries, but the list is clearly biased toward IPAs, with a few APAs that are actually IPAs and a token Imperial Stout. My favorite beer from Trillium is a Porter. He doesn't make that much that I'm that interested in, but Pretty Things is probably the best brewery, with the CBC better for Belgians and Sours. I used to love his historic British beer series, when he still made it. Day-to-day, I drink far more Notch than anything else from MA.
