A former senior editor for The New York Observer and founding editor of Curbed Boston, Acitelli has also written for The New York Times, New York Post, Redbook and All About Beer. In Audacity of Hops, he analyzes the history of craft beer across the U.S., charting the industries growth, new trends in home brewing, and what's next in the ever expanding world of beer.
