This giant cask, in Rhineland-Palatinate, has a volume of about 1.7 million liters, making it the largest in the world, large enough in fact to house a wine bar with space for 430 guests. It was built in 1934 by Bad Dürkheim cooper Fritz Keller, who fashioned each stave from a 40-meter spruce tree.

Magnificently, it is called the Giant Cask (Riesenfass). It surpasses the Heidelberg Tun, which had held the record previously.
