They call me the Godfather of Quadrupels — and I wear the title with pride. I am Kasteel Donker, the very first brew ever poured under the Kasteel name, and today, I reign as Belgium’s best-selling quad. From the historic castle brewery of Ingelmunster, my legacy has grown, sip by sip, heart by heart.

As you pour me, watch my dark brown cloak cascade into the glass, crowned with a thick, creamy beige head that lingers like a velvet curtain. On the nose, I entice with decadent caramel and toffee, laced with whispers of clove and spice — a prelude to the richness that follows.

Brewed with roasted malts and blessed with a robust ABV of 11%, I unfold on your palate with smooth sweetness, roasty warmth, and a long, elegant finish. There’s a touch of bitterness, a hint of spice, but above all, a depth of character that converts even the staunchest of light beer lovers. I’m not just a dark beer — I’m an experience.
