In order to eliminate the cold haze that was formed in the cold maturation tanks and to give its brightness to the beer, the beer is filtered after maturation.
At Brasserie du Bocq, only the Blanche de Namur is not filtered. Indeed, this beer has to be hazy when dispensed to the customer.

After the filtration, the beer is stocked into bright beer tanks. Prior to filling the bottles, and because Brasserie du Bocq only produces top-fermented beers refermented in the bottles, a small quantity of sugar and yeast is injected in the beer. After filling, refermentation will proceed following the same process as the first fermentation.
