In 2009, the Koningshoeven brewery reinstated an age-old tradition: aging La Trappe Quadrupel in oak barrels (also known as ‘barriques’).

This way of aging ale results in a unique, complex flavor, which varies from one type of barrel to another. Quadrupel can be conserved for many years, and is a real treat for true ale enthusiasts. And this is yet another ale that continues to ferment after bottling, while its rich taste and high tannin content are likely to even surprise many a wine drinker!

Pours a nice mahogany color - opaque. The sweetness is immediate. Other notes are a bit of smoke, toffee, leather, and some dark fruit. Taste is like sipping on a mild bourbon. That subtle thick sweetness comes through - a bit of alcohol heat as well. Lot of bread, caramel, nuts, figs, vanilla, and roasted malts.
