Love2brew and brew the world are both 1 to 1.5 away. I was using Brewers Apprentice for most of Mt brewing needs as they are about 30 minutes away. But I don't like then and have found their pricing to be expensive. they're comparable to shopping online prices. I've recently discovered that love2brew has fair pricing, and I don't mind the trip.
Flounder Brewing in Hillsborough has finally opened and is giving tours ( reservations required). I think they're done with Nov tours so I'm planning to visit Riverhorse this Friday at their new place in Ewing.
I got to visit Flounder last week. He's got a nice brewery with room to expand. Everyone we met there was incredibly nice and happy to geek out. They had a Saison, a pumpkin and their Hill Street Honey Ale on tap. They were all top notch, I went home with a growler of the pumpkin. Definitely worth checking out. You need to sign up for a tour though. I don't think they take walk in tours yet.
Ferment the World meets every 1st Monday at Harvest Moon in New Brunswick (about 12 people usually).
Just found out about another group that meets every 2nd Tuesday at Tapestre in Somerville (I hear it's about 4-5 people?).
WHALES meets in Woodbridge (large group, more organized, dues, events, etc). You can google WHALES for more info.
I've been to the one in New Brunswick a few times and plan to go to the one in Somerville in Jan.
OK, I've given up and decided to start a new group. I'm thinking it will be a very informal (no dues) meetup in the Somerset/Hunterdon/Warren area, focused mainly on sampling our brews. It's on Facebook here. https://www.facebook.com/groups/1427728654185293/
