St.Bernardus Abt 12 is Brouwerij St.Bernardus’ flagship and is considered as one of the best beers in the world. The Abt 12 is brewed following the original recipe from 1946. This bottle of St.Bernardus Abt 12 Oak Aged is brewed with that same original recipe and then matured for 6 months in Oak Calvados barrels before it is bottle conditioned. This maturation on oak barrels gives the beer a deeper and richer taste.
