Dan is a really nice guy and knows how to brew beer really well.
Carolina Brewer of The Year is best described here. http://cboysite.com/
MCAB is best explained here http://www.masterhomebrewer.org/info_page.htm#overview
The winners of home brew competitions along with MCAB and CBOY many times have their beers brewed by local breweries like Natty Green's, Liberty, Foothills and Olde Hickory. You probably have had a few and did not know it. At Natty Green's there is a tap call the "Alchemist" that features beer brewed by local home brewers and rotates based on availability.
