For me I think I would have gone Oskar Blues for Colorado. That's a state I struggle with because there's so many options. None of which likely make my top 5 brewery list. Avery, Great Divide, Odell, New Belgium, Left Hand, Epic, Boulder, Breckenridge, Tommyknocker, and I'm probably forgetting some. Colorado just has so many high quality offerings.
I alos don't think it's a duh for California, While Russian River is amazing, are they really "duh" better than Stone, Lagunitas, The Bruery, Sierra, Lost Abbey, Green Flash, I don't think so. I think you have several breweries to make a case. I think Russian River brews the best beer from California (Pliny) but does that make them the best brewer? Hard to say.
For the record, they didn't go for BReweries with reach. NJ, NH, and VT all are local offerings. Well known local offerings (though Stoneface is really new) but local offerings as you can't get Stoneface outside of NH yet (they seem to be moving in that expansion direction) you certainly can't get Hill Farmstead anywhere but VErmont, and Carton you can get in Central NJ, chunks of Northern and Southern NJ, NYC, and I think maybe they go to Philly now.
I agree with 2 out of those 3 myself, Carton is fantastic (though so are Kane, High POint, and a few others, but given the Thrillist NYC spin I'mnot shocked it's Carton) Hill Farmstead is the best brewery I've ever had (serious, if you're in Vermont and you see them, get that beer, I've had none of them let me down yet and I think I've had 10 different beers at this point, some of the ones I"ve had have been my favorite of that style)
For the record, my picks for states I have a hell of a lot of experience drinking in or beerrs from that state.
Pennsylvania - Victory - I huffed and puffed before, and it comes down to them vs Weyerbacher, I prefer the flavors form Weyersbacher more, but Victory is more consistent. I had an issue with an aged Weyerbacher that got a lacto-infection. Still, their offerings are amazing.
NJ - Kane - I've beaten the Carton drum a lot, and they're truly amazing. Boat, 077XX, Epitome, all amazing, but I think Kane just slightly edges them out. Carton is a riskier brewer, they do crazier things, Kane is more interesting brewer though. Head high and especially Overhead are great IPAs (Overhead the imperial) and their rotating seasonals include some truly great beers like Morning Bell and Port Omna. They just slightly edge out Carton and right now those 2 are the lead horses for me. NJ has some other up and comers and some of the older brands like Riverhorse, Cricket HIll, and Flying Fish are great. Ramstein is probably right there with them, but I'm not as in love with their styles.
Maryland - Heavy Seas - I'm a little biased here, they were an early craft love of mine so I stuck with them. Great brewery who does a lot of beers well. Not a top brewer for me, but Loose Cannon is fantastic.
New York - Ommegang - Fully admit, this may be a case of the Physical brewery impressing me so much. First I'll say they brew high quality ales, they hit their mark. Allagash is my main Belgian supplier, but Ommegang is a pretty close second. But holy **** the brewery.
New Hampshire - Kelsen - Discussed this a little earlier. There's a really cool brew pub by me, they specialise in German and belgian ales with some lagers as well. They rock, I like them a lot. Kelsen is superior for my money though.
Vermont - Hill Farmstead - Already touched on this
Maine - Allagash - Maine Beer co is amazing. but Allagash is just a touch better in my opinion. THough that could partially be skewed by the insane bottle prices on Maine Beer, but their product rocks. Allagash again just edges them out, sorry Maine.
Massachusetts - Tree House - Ok this may be premature, I've only had a few of their offerings, but I was really impressed, I'm hoping to got to see them shortly.
That's about as far as I want to put my expert stamp on things. I have tried many beers from many other states, but those are the states I've travelled to and tried more local offerings.
