Beer Fountain

"Hops and malt, may the Lord preserve it"
The beer fountain in a niche in the sidewalk at the corner of Oskar-von-Miller-Ring and Brienner Straße, which was erected there in 1958 when the brewery was built. On the day of the unveiling of this mighty basin, which weighed over 700 kg, the citizens of Munich saw a lady dressed in a white dirndl, standing in the middle of the basin and pouring real beer into steins at the tap system mounted on the middle piece, the water source, and to onlookers handed out as a free beer. To celebrate the day, the water supply line was connected to a beer keg set up in the basement of the brewery.

In winter, the wells are usually covered due to the risk of frost.
So also in Munich.
Therefore, most of the splendor is not to be seen.

On Bavarian Beer Day, free beer often bubbles out of the fountain.
