I remember the micro brewery at Arcen just a few miles south of Laarbruch, on the R. Maas. They make over a dozen kinds of beer ranging from Trappist style ultra strong stuff to fairly light 'blond', all delicious. All the products were available in the bar next door. One of them was served in a glass boot and you had to surrender a shoe before being served. The shoe went into the freezer (ah those crazy Cloggies).
De Hertog Jan Proeberij was the name of the bar. Proeberij might translate as 'testing facility'; it certainly tested my ability to remain vertical. Happy days.
