Besides, living here in NC where there are now so many excellent small breweries, I would be a fool to stick to the mega breweries.
A couple of my favorites are The Duck-Rabbit Craft Brewery and Mother Earth Brewing. Both of these are located <1 hour from my house so I can always be sure it's fresh!
It`s expensive but the German beer purity law, Reinheitsgebot, says Barely, Hops, and water. I tend to stick with them, the Germans do brew some good beers to choose from.
