Borg is also a Norwegian brewery:

Borg breweries' history starts in 1855 when Lande Gaard brewery, which would later be known as Sarpsborg bryggeri (bryggeri = brewery), was established by Hans Peter Hafslund and other significant farmers in the Skjeberg area. Brewing commenced the following year.

In 1889, Sarpsborg bryggeri and Halden bryggeri joined forces. The company was now called Borg Bryggerier.

Today, Hansa Bryggerier owns Borg Bryggerier.

Borg's current product range:

An interesting fact about Borg Pilsner is that a large amount of the brew is exported to Sweden, the border lies some 15-20 kilometres from the brewery. And because of the extremely high Norwegian alcohol taxes, Norwegians living near the Swedish border smuggle large amounts of the same beer back into Norway...
