One of the most sought-after beers brewed in North Carolina debuts Friday at Foothills Brewing in Winston-Salem. 

The first keg of Sexual Chocolate, a rich Russian Imperial Stout, is tapped at 5 p.m. at the brewery's pub downtown and once the bar closes at 2 a.m. the diehards begin camping out overnight to buy 22 ounce bottles that go on sale at 10 a.m. Saturday.

The beer won silver at the World Beer Cup in 2010 and its sister, Bourbon Barrel Aged Sexual Chocolate, took gold the same year at the Great American Beer Festival.

The bottles are $15 a piece and limited to four per person. They sell out within a couple hours.
