Hertog Jan Grand Prestige Vatgerijpt 2022 represents a deliberate collaboration between brewers Gerard and Micha, who travelled to France to study traditional craftsmanship. The base Grand Prestige spent months maturing in oak casks previously used for Bordeaux Merlot wine. The outcome is a Bière du Soir—an evening beer—with deep reddish-brown hue.

The beer presents chocolate and cherry character alongside a subtle acidity drawn from the wine-seasoned wood. A dry, wine-like finish completes the profile. At 11% ABV, this barleywine distinguishes itself not merely through strength but through the refined influence of French oak maturation.
