For Six Pack with Zack #4, Zack Roskop brings Aaron McClain on his first visit to the SOS shop. Aaron's Crafty Bastard brewery is widely regarded as on of the top craft breweries in Knoxville. Aaron's experimental brewing practices have helped Crafty Bastard happen upon stalwart beers that have challenged conventional craft beer trends and standards. Zack and Aaron indulge Ben's curiosity on the long term viability of craft breweries, and help answer the "are we too saturated with craft beer options" question.
