Tart of Darkness is a traditional stout that we aged in used oak barrels from The Bruery that had previously housed beers such as Cuivre™ or Black Tuesday®. We then brought them over to Bruery Terreux, added our special blend of souring bacterias and wild yeasts and watched nature take its course. The result is a perfectly tart yet awesomely dark and roasty, sour stout. Not a style you will see very often, and in our opinion, not a style seen often enough. This unique stout has notes of tart plums, roasted coffee, vanilla and oak.
