Kolleke Oude Jan from Stadsbrouwerij Van Kollenburg in 's-Hertogenbosch is a dark Dubbel with 7% ABV. Brewed with three varieties of barley malt and a touch of licorice root, this deep brown beer presents a full beige head and a rich, malty character.

The palate is malty and full-bodied, with fruity notes and subtle sweetness. Apple syrup appears in both the aroma and flavour profile, creating a beer that bridges oud bruin and sweet stout characteristics. This beer represents the foundation of the city brewery's identity.
