Quadrupel

Quadrupel and Belgian Dark Strong are different names for the same beer. And regardless of what you call the style, it is a dark, strong, complex ale with rich malts, dark fruits and a touch of spice. The style shares many characteristics with the Dubbel, but is more intense in almost every way. With ABV ratings from 8-12%, the alcohol is apparent, but should add 
a smooth warmth without being hot.
