Röda Ulven, meaning “The Red Wolf” in Swedish, was established in 1946 when the company’s first brand was naturally named “Gösta Hannells Surströmming.” Röda Ulven soon became synonymous with fermented herring with its eye-catching packaging and is Sweden’s leading brand today. The brand has taken its name from Ulvön, also known as Wolf Island, which is seen to be the Mecca of Swedish surströmming. The word “Röda” (red) comes from that the island completely glows in red thanks to the beautiful red Rapakivi granite.

What is Surströmming?
Surströmming is a traditional Swedish dish from northern Sweden that arose during the 16th century when Sweden had a salt shortage. Small Baltic herring are caught in the spring, salted and left to ferment at leisure before being stuffed in a tin about a month before it hits the tables and shops. The fermentation process continues in the can – ‘souring’ as the Swedes refer to it – and results in a bulging tin of fermented herring. The aroma is pungent, and the taste is rounded yet piquant with a distinct acidity.
The Surströmming Challenge
The surströmming fish challenge has gained popularity online, especially on social media platforms like YouTube and TikTok. Several videos have gone viral and feature a person or people eating this Swedish food, often depicting over-the-top reactions to the smell. However, most people aren’t eating it the traditional way. Opening a can without preparing the right sides—like bread, potatoes, butter, and onions—can lead to an overpowering experience that doesn’t do this Swedish delicacy justice.
In an unforgettable moment on Good Mythical More, YouTubers Rhett and Link, joined by PewDiePie, opened a can of surströmming and immediately faced the intense smell and unexpected spray from the can. PewDiePie, real name Felix Kjellberg, who is Swedish, joked about how the dish is typically eaten during traditional celebrations, usually with plenty of drinks to lighten the mood.

For the best experience, serve surströmming wrapped in buttered tunnbröd, a traditional Swedish flatbread with a slight sweetness.

Accompany with beer, snaps and lots of friends. A shot of vodka or aquavit enhances the experience.
The Taste Experience
Despite the pungent aroma, surströmming is often described as tasting much milder than it smells. That being said, it still boasts strong notes of salt, acid, and umami. Enthusiasts describe the taste as rich umami. Upon tasting, you encounter a sharp sourness from the lactic acid produced during fermentation, balanced by a subtle brininess and an underlying sweetness that emerges as the fish mellows. The flavor profile is complex—initially bracing, yet layered with hints of salt, tang, and a mild umami depth.
