Discovering Surströmming: The Unique World of Swedish Fermented Fish
Swedish fermented fish, particularly known as surströmming, is a fascinating culinary tradition that dates back to the 16th century. This dish, made from fermented Baltic Sea herring, is infamous for its potent aroma and distinct sour taste. In this blog post, we will explore the origins, production, cultural significance, and unique characteristics of surströmming, providing you with a comprehensive understanding of this iconic Swedish delicacy.
The Origin of Surströmming
Surströmming has its roots in Sweden, where it has been enjoyed for centuries. Originally, the fermentation of fish was a means of preservation before modern refrigeration methods emerged. The process utilizes herring that is caught in the spring, specifically before spawning, between April and May. This timing is crucial as it ensures the fish are at the right stage for fermentation. The traditional methods have been preserved, making surströmming a significant part of Swedish culinary heritage.
The Chemical Process Behind Fermentation
The fermentation of surströmming involves a carefully controlled process that takes at least six months. Initially, the fish are marinated in a strong brine for about 20 hours, followed by a weaker brine solution. This process kicks off the fermentation, which occurs at temperatures ranging from 15 to 20 °C (59 to 68 °F). During this time, various compounds are produced, including propionic and butyric acids, along with hydrogen sulfide, which contribute to the dish’s distinctive and often polarizing odor (

Production and Market of Surströmming
Surströmming is primarily produced in northern Sweden, where it enjoys immense popularity. An estimated 2 million Swedes indulge in this dish annually, particularly during its “premiere” celebration on the third Thursday in August. This event marks the release of the new season’s catch, a tradition that highlights the cultural importance of surströmming.
However, the production of surströmming faces challenges, particularly due to the declining herring stocks in the Baltic Sea. Unsustainable fishing practices have led to shortages, causing retailers to sell out their supplies quickly. This highlights the need for responsible sourcing and sustainability in the production of this traditional dish.
How to Prepare and Enjoy Surströmming
Traditionally, surströmming is enjoyed outdoors due to its strong smell. It is often served on tunnbröd, a type of Swedish flatbread, accompanied by various toppings such as potatoes, red onions, and sour cream. The combination of flavors can create a surprisingly delightful experience for those who are willing to try this acquired taste.
The Surströmming Challenge
In recent years, surströmming has gained international fame through viral “surströmming challenges” on platforms like YouTube and TikTok. These challenges feature individuals attempting to eat the fermented fish, often resulting in humorous reactions due to its notorious smell. This trend has sparked interest and curiosity around surströmming, making it a subject of both intrigue and disgust (

International Opinion and Cultural Incidents
Surströmming is not without its controversies. It has faced legal challenges, such as a 1981 court ruling in Germany where a landlord evicted a tenant due to the overwhelming smell of surströmming. Additionally, some airlines have prohibited the transportation of surströmming cans due to the risk of explosion from pressure during flight. These incidents illustrate the polarizing nature of this dish and its cultural implications beyond Sweden’s borders (
