Cuvée des Jacobins Rouge is a Flemish Sour Ale, red in color with a beguiling balance of malty sweetness and acidic sharpness. It is made from spontaneously fermented and barrel-aged beer of at least 18 months in age. The beer is cooled overnight in a large, shallow metal vessel called a coolship and then fermented and aged in large oak foudres which are made in France and assembled on-site at Bockor.
