At Kasteel Brouwerij Vanhonsebrouck we mature our Kasteel Tripel in recycled cognac barrels. This beer style is called ‘Barrel Aged’, aging beer in recycled barrels. Our brewer fills previously used cognac barrels with Kasteel Tripel to ensure that the beer retains the taste of cognac without losing its own identity. The Trignac is a full-mouthed degustation beer and appeals to anyone who loves beer and cognac!
