NoDa Coco Loco for a real heavy beer. It is some sweet nectar though.
Lonerider Bad Penny Brown Ale for something dark but light on the stomach.
NoDa Jam Session IPA or Sweetwater 420 for a good IPA.
NoDa's seasonal beers are solid for a change of pace.
Cheaha Brewing Co. has a really good porter.

For reference NoDa Brewing Co is local here in Charlotte. They also happen to sponsor the rugby club I play for, so we tend to get a fair amount of free beer from them.

Lonerider is in Raleigh and have a pretty sweet taproom to drink in.
Sweetwater just opened a brewery here too so I'll be frequenting that place soon.
Cheaha is in Anniston and if you haven't been you're missing out.
