Mack has been part of Tromso since 1877, and the old city-centre brewery is still one of the town's best-known names. It long billed itself as the world's northernmost brewery, a claim now disputed by Svalbard, but the Arctic bragging rights are less important than the local attachment to the place.
Guided tours run only on limited days and usually need a minimum group, so check ahead rather than just turning up. The brewery is closely tied to Tromso's beer hall culture, making it a good stop for visitors interested in the city's everyday history as much as its polar past.
