Carlsberg's unit in Norway is set to sell its oldest brewery in the country.

Ringnes, which Carlsberg took complete control of in 2004, confirmed today (17 April) that it will sell its brewery in Arendal, in the south-east of the country, to a group of local investors. Financial details behind the divestment were not disclosed.

"Ringnes has earlier made it clear that the Arendal brewery does not fit into the future production structure in Ringnes, and various structural solutions have been considered," the company said. "One of these has been a sale of the brewery to local investors.

"The sale of Arendal will increase the efficiency of Ringnes' production structure."

The Arendal facility employs 145, the unit said, and is one of Ringnes' three breweries in Norway. The site was founded in 1839.

Earlier this year, Carslberg confirmed that Ringnes was looking to reduce its costs and employee numbers going forward.
