Bruges, Belgium (CNN)Under the streets of the medieval Belgian city of Bruges, a full two-mile pipeline is being built -- exclusively for beer.
The pipeline, which is expected to be completed this summer, will pump beer at a speed of 4,000 liters (about 1,057 gallons) an hour from De Halve Maan Brewery in the center of Brussels to its bottling plant outside the city.
"I think we are the very first ones to do this ever in the world," says Xavier Vanneste, whose family has run the brewery for 160 years.
