Tart of Darkness is a traditional stout aged in used oak barrels from The Bruery that had previously housed beers such as Cuivre™ or Black Tuesday®. The beer was then brought to Bruery Terreux, where they added their special blend of souring bacterias and wild yeasts. The result is a tart yet dark and roasty sour stout. Not a style you will see very often, this unique stout has notes of tart plums, roasted coffee, vanilla and oak.
