[2] In the 19th century, the water in the lower part of the Aker River became too contaminated to brew beer, and the brewery needed more space.
The company also changed its name to Foss Bryggeri (literally, 'Falls Brewery') to reflect the new location.
After the operations were relocated upriver in 1897, the old cellars were used for various purposes, including vegetable storage during the Second World War.
[6] In 1897, the brewery built a large factory at Vøyen Falls, where a brick factory (Øvre Foss teglverk or Foss teglverk)[7] had been located, at what is today the level area and parking space between the old Ringnes Brewery and the Aker River.
[10] The Foss Brewery won a gold medal for its beer at the Paris world's fair in 1900.
