Double barrel-aged sour stout aged in bourbon barrels followed by rum barrels

Tart of Darkness is our sour stout aged in oak. Brewed to resemble a stout at its foundation, the journey into tartness begins with fermentation in large oak puncheons at Bruery Terreux, where it’s treated to a special blend of souring bacteria and wild yeast cultures. Following a slow but wildly active fermentation, the beer is transferred for extended aging into used oak barrels including emptied bourbon barrels from The Bruery that previously held Black Tuesday. For this special edition, we aged the beer for another year in rum barrels sourced from Martinique.
