Surströmming, a traditional Swedish fermented herring dish, has gained notoriety worldwide for its pungent aroma and acidic taste. While some people enjoy this unique delicacy, others find it unbearable. But what makes surströmming taste so bad? In this article, we’ll delve into the history, production process, and science behind surströmming’s distinctive flavor.
A Brief History of Surströmming
Surströmming has its roots in 16th-century Sweden, where it was created as a way to preserve herring. The name “surströmming” literally translates to “sour herring” in Swedish. The dish was originally made by fermenting herring in a mixture of salt, water, and lactic acid, which helped to preserve the fish and give it a distinctive flavor.
Traditional Production Process
The traditional production process of surströmming involves several steps:
- Fermentation: Fresh herring is mixed with salt, water, and lactic acid, and then left to ferment for several months. This process breaks down the proteins and fats in the fish, creating a strong, acidic flavor.
- Ripening: After fermentation, the herring is left to ripen for several more months. During this time, the flavors mature and develop a stronger, more pungent aroma.
- Canning: The fermented herring is then canned and sold as surströmming.
The Science Behind Surströmming’s Flavor
So, why does surströmming taste so bad? The answer lies in the science behind its production process.
Volatiles and Compounds
During the fermentation process, the bacteria in the herring break down the proteins and fats, creating a range of volatile compounds. These compounds, including trimethylamine, ammonia, and hydrogen sulfide, are responsible for the strong, pungent aroma of surströmming.
Trimethylamine
Trimethylamine is a naturally occurring compound found in many types of fish. However, during the fermentation process, the levels of trimethylamine in surströmming increase significantly, giving it a strong, fishy flavor.
Ammonia
Ammonia is another compound produced during the fermentation process. It has a strong, pungent smell and is responsible for the characteristic “rotten” flavor of surströmming.
Hydrogen Sulfide
Hydrogen sulfide is a toxic compound produced during the fermentation process. It has a strong, rotten egg smell and is responsible for the characteristic “sulfur” flavor of surströmming.
Health Benefits of Surströmming
Despite its strong flavor, surströmming has several health benefits. It is high in protein, omega-3 fatty acids, and various vitamins and minerals.

What is Surströmming and where does it originate from?
Surströmming is a traditional Swedish delicacy that originates from the northern parts of the country, particularly in the provinces of Norrbotten and Västerbotten. It is a fermented herring dish that has been a part of Swedish cuisine for centuries. The name “Surströmming” literally translates to “sour herring” in Swedish, which refers to the fermentation process that gives the dish its distinctive flavor and aroma.
The fermentation process of Surströmming involves allowing the herring to break down naturally by bacteria, which produces lactic acid and gives the fish its characteristic sour taste. The herring is usually caught in the spring and then left to ferment for several months, typically between 6 to 12 months, before it is canned and sold. The fermentation process is what sets Surströmming apart from other types of pickled herring, and it is this process that contributes to its strong smell and flavor.
Why does Surströmming have such a strong smell?
Surströmming is infamous for its strong and pungent smell, which is often compared to rotten eggs, gasoline, or sewage. The smell is caused by the fermentation process, which produces a number of compounds that are responsible for the odor. One of the main culprits is a gas called trimethylamine, which is produced when the bacteria break down the proteins in the fish. This gas is also responsible for the smell of rotting fish and is often used as a benchmark for measuring the smell of Surströmming.
The smell of Surströmming is so potent that it is often described as overwhelming, and it can linger for hours after the fish has been opened. In fact, the smell is so strong that it is often recommended to open the can of Surströmming outdoors or in a well-ventilated area to avoid the smell spreading to other parts of the house. Despite the smell, many Swedes enjoy Surströmming and consider it a delicacy, while others find it too pungent to eat.
What does Surströmming taste like?
Surströmming has a distinctive taste that is often described as sour, salty, and umami. The fermentation process gives the fish a tangy flavor that is similar to sauerkraut or kimchi. The taste is often compared to a strong blue cheese, such as Gorgonzola or Roquefort, but with a fishy twist. The texture of Surströmming is also unique, with a soft and mushy consistency that is similar to canned tuna.
Despite its strong smell, Surströmming is often served as a snack or appetizer, and it is usually accompanied by boiled potatoes, sour cream, and chopped onions. The creamy texture of the sour cream helps to balance out the acidity of the Surströmming, while the boiled potatoes provide a neutral background flavor. For those who enjoy strong flavors, Surströmming can be a delicious and unique culinary experience.
Is Surströmming good for you?
Surströmming is a nutrient-rich food that is high in protein, omega-3 fatty acids, and various vitamins and minerals. The fermentation process involved in making Surströmming also creates a number of beneficial compounds, including probiotics and antioxidants.
