Departures of Flying Dog, Guinness reflect industry trends, experts say

Weeks after Guinness filed plans to shutter its Baltimore County manufacturing plant, Flying Dog Brewery this week announced it will close its Frederick facility. But the departures are more indicative of industry trends than of a brewery problem in the state, say industry experts. Guinness’s parent company, Diageo North America, plans to close its Baltimore County site on June 9, according to a March filing with the Maryland Department of Labor.
