The St. Sebastiaan Grand Cru is a golden, heavy fermented abbey beer with a distinctive fruity aroma and subtle hints of elaborately selected herbs. This Grand Cru has a nice balance between sweet and bitter and has a nice full-bodied taste with a soft, malty aftertaste. It is re-fermented by the brewery in the jug and or bottle. The result is a nice, clear beer with a wonderful aroma and, for those who love it, a touch of yeast at the bottom of the bottle.

In 1981, the mayor of Brugges asked the brewery to create a strong blond beer for the inaugration of the statue of Sint-Arnoldus, the saint of all beer-brewers. However, the beer became so popular, that the demand continued. A strong and rich beer with a subtle mixture of 6 different kinds of malt. The taste is strong with a lot of hop (Saaz and Styrian Golding) of the best quality.
