Why collaborate with just one or two breweries when you can bring 8 to the table.
BrewDog has done just that by gathering Cloudwater, DEYA, Magic Rock, Northern Monk, Stillwater, The Bruery and Seventh Son to brew a New England-style IPA (in Scotland).
“…each of the eight breweries selected a hop to go onto the brewsheet. Magnum, Mandarina Bavaria, Chinook, Hallertaur Blanc, Citra, Nelson Sauvin, Mosaic and German Comet.” and the brew comes in (somehow) at 8% ABV.
This one you will have to hunt for.
