As most beer enthusiasts will know, the Cantillon Brewery is well known for brewing authentic Lambic style beers in the same location using the same methods since 1900. When they say "nearly nothing has changed during the last century", they really mean it! Walking through the brewery is like being transported back in time.
I was the first person to arrive for a tour that day (what's wrong with drinking a lambic for breakfast?) and wandered through the brewery alone on the self-guided tour. Afterwards, I was offered a glass of their Gueuze by one of the brewers I had seen shovelling out a fermenter. Now, not everyone can appreciate the funky sourness of a Gueuze style of beer. I've heard the flavour and aroma compared to some pretty sick stuff by first-time tasters. I admit, it is an acquired taste. However, if you are able to get past that initial sourness, you can start to appreciate the other subtle flavours that the beer contains. And, since the process involves blending beers of different ages, no two batches of Gueuze will ever taste the same.
If in Brussels (or close to Brussels or if you can even just find Brussels on a map), I highly recommend dropping by the brewery and taking the tour. The experience of standing in a 100+ year old family-owned brewery and sharing a beer with the brewer himself is hard to describe.
