Sour monkey is the name of a beer made from fermented monkey excrement.
It’s made by fermenting the excrements of a goat and adding it to a barrel of beer.
Some people enjoy it as a treat, while others, such as the Swiss, drink it for medicinal reasons.
According to the Guinness World Records, Sour Monkey has been brewed in Belgium since 1883, and the first brew in the country was made in the 1892-93 season.
The brewery in Brussels has a long history.
It was founded in the 16th century, but the brewery was sold to a company that became known as the Burgundy Bierwerks in 1876.
The Belgian brewery is still in business today.
