Duvel is the classic Belgian golden ale. Although it is very strong (8.5% ABV), the beer is extremely light in color and dry in taste. The dense, white head that sits above the beer lasts until the beer is done. In the US, bottles of Duvel often show some oxidation in the aroma. Brewing it fresh at home gives you a glimpse of what it tastes like in Belgium. The yeast will not have an easy job here; they are dealing with a high-gravity, high-adjunct wort. Help them (and yourself) out by making a big yeast starter for a high cell count at pitching.
