Duvel is the classic Belgian Golden Strong ale. It is light in color, high in alcohol, and suprisingly easy to drink.

The Beer - A pretty straight forward malt bill - be sure to use good quality Pilsner malt (ideally Belgian, but whatever will work). A little light Crystal and Aromatic malt is added in for interest. Carapils is included to aid in head retention.
Using a light candi sugar or table sugar will add almost fully-fermentable sugars and prevent this high-alcoholic beer from being way too sweet.

Noble hops balance sweetness with a smooth but subtle bitterness.
