5 am. A storm sweeps the clouds from the sky and the full moon casts a pale strip of light on the tiled floor of the Weltenburg brewery. The working day of Ludwig Mederer, master brewer in Weltenburg abbey brewery, began half an hour ago. Today the Barock Dunkel is being brewed. Ludwig Mederer climbs down into the historical rock cellar to the metre-high tanks, in which the beer is held to mature for six weeks. Hoses lie around on the wet ground like lethargic snakes. Everything is going perfectly. Just as well – it will be a long day.
