Jopen Ongelovige Thomas is Haarlem brewery Jopen's bold interpretation of a quadrupel—a strong dark beer at 10% ABV that doesn't hold back. Rich roasted malt flavours form the backbone, layered with caramel, toffee, and hints of dark berries and fresh bread. Subtle notes of chocolate and nuts add further complexity.

The palate strikes a balance between sweetness and a gentle bitterness, with roasted character complementing the fruity undertones. Warming and smooth, it rewards slow sipping, particularly during autumn and winter months. This beer earned Jopen recognition at the 2015 World Beer Awards as Europe's Best Strong Dark Beer.
