Cabin owner Inge Haugen found the forgotten can after peeking under the eaves to find a swelling can of surströmming that had been expanding over the past two and half decades. He reckoned the bulging tin had raised the cabin's roof by about two centimetres.
The find left him concerned that the can might explode at any moment, prompting him to warn his neighbours. Norway's Armed Forces were also notified about the impending "stink bomb".
However, the discovery of the can in Norway has the fermented herring aficionado's mouth watering at the prospect of tasting surströmming that's been aged to perfection over the past 25 years.
"I have my own collection of vintage surströmming with several cans that are more than 15 years old," he said.
"The taste certainly gets richer with age. The longer you wait to open a can, the more complex the flora of tastes you get."
The level of stink is ludicrous.
