Bridge Road Brewers together with gypsy brewer Mikkel Borg Bjergsø of Mikkeller created a one off brew one Friday evening of March 2012. The result is The Dark Harvest. Inspired by the timing of the collaboration, it was decided to make a dark beer, using locally grown fresh hops. Of several research hops being grown at Rostrevor Hop Garden, one variety stood out for selection and was harvested just hours before being added to this beer.
