Things that happened in 2015: folks packed movie theaters to watch Matt Damon survive on mars, Justin Bieber hit the charts with at least 3 different songs, and the crew at Allagash began brewing Coolship Resurgam.

The brewers allowed that first spontaneously fermented brew to age in French Oak wine barrels for 3 years. Then, they blended it with two more Wild Ales aged one and two years respectively, creating an intricate, endlessly complex Cuvee-style Ale. They bottled it in 2018, and it’s been slumbering in Allagash’s cellar ever since.
