Rather different from other breweries is Belgium's Cantillon.
This brewery, based in Brussels 15 minutes' walk from the Grand'Place and ten minutes walk from the Midi station, specialises in lambic beers, using natural yeast for spontaneous fermentation. Its acid and even sulphurous Gueuze and other beers have a distinctive character and invite either wild love - or bitter hatred.
The brewery is open 9-5 every weekday and 10-5 on Saturday. The entrance price of EUR 3.50 includes a glass of Gueuze, which is pretty good value.
