In March of last year, we drove to Marquette to brew the first of this special series of beers: The Laurentian Series. Named after the watershed in which the Great Lakes reside, these beers will be brewed and then cooled at each of the Great Lakes. We brewed this particular batch at Ore Dock Brewing, and cooled it in a mobile coolship, utilizing the night air blowing in off of Lake Superior. After cooling overnight, the tank was closed and hauled back to our brewery, where the cooled wort was transferred into oak barrels. Inside the barrels, the microbes from the lake’s breeze began to ferment the beer, imparting their unique character over time. No additives were introduced for flavoring, with the highlight being the native flora of Lake Superior and Marquette, MI, imparting aromas of hay, sweet dough, and stone fruit, along with the oak character of the barrels.
