Hertog Jan Dubbel is a traditional top-fermenting dark beer. The designation 'dubbel' refers to the double amount of ingredients used. Hertog Jan Dubbel is tasted by all senses, allowing for an optimal enjoyment of color, smell and taste. Firstly you poor it into a glass and marvel at the foam and the pretty reddish brown color. Then you smell the full, soft aroma. You take a sip and taste the rich, malty character. And finally, you enjoy the somewhat sweet aftertaste. This traditional beer has an alcohol percentage of 7.3 %. The secondary fermentation in the bottle creates a fresher and richer taste and aroma.
