It all starts with a Duvel that has been stored upright in a cool place. Otherwise, the yeast at the bottom of the bottle will be mixed with the beer.
The Duvel is ready to drink if it has been chilled in the refrigerator to the ideal temperature of +/- 4°C . What is equally important is a clean, dry Duvel glass at room temperature.
A beer that takes 90 days to brew should be poured with respect, so take your time and pour the beer slowly into the glass that is held at a slight angle.
Avoid contact between the bottle and the glass and gradually lift the bottle a bit higher to form a full, creamy head.
You should also leave approximately 1 cm of beer in the bottle. This contains the yeast which can make the beer somewhat cloudy and bitter.
For a rich, full head, slowly straighten the glass to an upright position. A head forms that ideally should start at the height of the Duvel-logo. Do not allow the beer to foam excessively but pour until it reaches just below the edge of the glass.
Admire and enjoy. To your health!
