🌍 Belgium · Quadrupel · One of 8 Quadrupels in hopIQ

A dark amber abbey quadrupel of the Belgian range, first brewed as an Easter beer and now available year-round. Tasters describe caramel, brown sugar and dried fruit on the nose, with raisin and plum behind them. The palate is sweet and bitter at once and notably round, with toffee, dark fruit and a hint of spice over a dense malt body. The finish is broad, warming and clearly alcoholic, with hop and malt held in balance. Caramel colour is used to deepen the shade.

◐ Taste

The palate opens with rich caramel and brown sugar sweetness, followed by a smooth, full-bodied malt backbone that carries flavors of dark bread and roasted character. Subtle fruity esters and spice notes emerge mid-palate, while the restrained bitterness (28 IBU) allows the complex malt and yeast interactions to shine without any harsh edges.
