With the arrival of bock beer, the brewers mark the start of autumn. In the old days this was the first beer that was made after the summer with the fresh harvest of malt and hop. Hertog Jan was the first in The Netherlands who brewed Bockbier top-fermenting. This way, the flavor of the beer comes to its own better. Hertog Jan Bockbier has a pronounced full and creamy flavor, in which a slight whisp of caramel can be found.
