Product Overview
Röda Ulven Surströmming Fillets are fermented herring fillets packed in brine and sealed in a traditional metal can. Surströmming is a Swedish fermented-fish food associated particularly with northern Sweden and the Baltic herring tradition. The product represented by ASIN B0CG3T3XY9 is identified as the fillet version of Röda Ulven surströmming rather than the whole-fish form.
The container has a stated total capacity of 400 grams and a drained fish weight of 300 grams. Public product information identifies the contents as fermented herring fillets with water and salt. Fermentation begins before canning and continues after the fish has been sealed, which can create internal pressure and cause the metal container to become rounded or swollen.
Surströmming has an unusually strong aroma resulting from the fermentation process. It is traditionally served in relatively small portions with foods such as Swedish flatbread, potatoes, onion, and cultured dairy products. Because of the pressurized container and strong odor, careful handling and outdoor opening are commonly associated with this type of fermented fish.

Common Uses
Röda Ulven Surströmming Fillets are intended as a ready-to-serve fermented seafood product. Surströmming is traditionally associated with seasonal Swedish meals and social gatherings centered around the annual surströmming tradition.
- Serving as part of a traditional Swedish surströmming meal.
- Eating with Swedish flatbread, potatoes, and chopped onion.
- Serving with cultured dairy accompaniments such as sour cream or similar products.
- Using small portions of fermented herring as the primary flavored component of a flatbread meal.
- Exploring traditional Scandinavian fermented-food preparation and serving customs.
Maintenance & Care
This is a preserved food rather than a reusable household product, so maintenance primarily involves appropriate storage and handling. Refrigerated storage is commonly specified for long-term storage of Röda Ulven surströmming.
- Keep the unopened can refrigerated for extended storage.
- Avoid unnecessary heat exposure because fermentation continues inside the sealed container.
- Handle a swollen can carefully because internal fermentation can create pressure.
- After opening, keep remaining food refrigerated in an appropriate covered food container rather than relying on the opened metal can for extended storage.
- Follow any storage dates and instructions printed on the individual package.
Safety Information
This product contains herring and therefore contains fish, a recognized food allergen. Individuals with fish allergies should not consume it.
Surströmming continues fermenting after canning. Gas produced during fermentation can pressurize the container and cause noticeable swelling. A rounded can is therefore associated with this particular fermented product, although any package showing leakage, severe damage, or an uncertain storage history should be handled cautiously.
- Open the container carefully because pressurized brine may escape when the seal is broken.
- Opening outdoors is commonly practiced because of the strong fermentation odor.
- Keep the container away from the face while initially breaking the seal.
- Do not consume food from a can that is leaking or physically compromised in a manner inconsistent with normal surströmming fermentation.
- Follow the date and handling information printed on the actual can.

Product History
Röda Ulven is a long-established Swedish surströmming brand whose history dates to 1946. The name translates approximately as “The Red Wolf” and is associated with Ulvön, an island closely connected with Sweden’s surströmming tradition.
Surströmming itself has a much longer history than the Röda Ulven brand. Fermented Baltic herring has been part of Swedish food culture for centuries. Modern metal canning later made it practical to distribute the fermented fish beyond the coastal areas where the food originated.
Röda Ulven is produced in multiple forms, including traditional whole-fish and fillet versions. The product documented on this page is specifically the fillet format.

Frequently Asked Questions
What is Röda Ulven Surströmming?
It is a Swedish preserved seafood product made from salted and fermented herring. This version contains fillets rather than whole fish.
Does this version contain whole herring?
No. The product identified by this listing is the Röda Ulven fillet version of surströmming.
Why can a surströmming can become swollen?
Fermentation continues after the fish is sealed inside the can. Gas generated during this process increases internal pressure and can produce the characteristic rounded appearance of a mature surströmming container.
How is surströmming normally opened?
It is commonly opened outdoors because of its concentrated odor. The container should be opened cautiously because pressure inside the can can force brine or gas outward when the seal is broken.
Does surströmming require cooking?
Surströmming is traditionally eaten as fermented preserved fish rather than cooked immediately before serving. Consumers should follow any preparation instructions printed on the individual package.
How should the product be stored?
Refrigeration is recommended for longer-term storage. Storage instructions and date markings on the individual can should take precedence over general guidance.
What ingredients are used?
Public information for Röda Ulven Surströmming Fillets identifies herring fillet, water, and salt as the ingredients.
Does the product contain a major allergen?
Yes. Herring is fish, so this product contains a fish allergen.
How is surströmming traditionally served?
Traditional Swedish serving methods often combine the fermented fish with flatbread, potatoes, chopped onion, and cultured dairy accompaniments. Regional and household serving customs vary.
What are the dimensions of the can?
Reliable package dimensions for the specific B0CG3T3XY9 product record were not verified. Dimensions are therefore not stated rather than estimated from similar cans.
What material is the container made from?
The product is supplied in a traditional metal food can designed to contain the fish and brine during fermentation and storage.
Does this product require installation?
No. It is a packaged food product and has no installation requirements.
Is a warranty provided?
No verified manufacturer warranty information was identified for this packaged food product. Any retailer-specific return or satisfaction policies are separate from the product specifications.
How can this specific product record be identified?
The product record can be distinguished by the Röda Ulven brand, surströmming fillet description, 300-gram drained format, and its associated catalog identifier.
Buying Considerations
Surströmming differs substantially from ordinary canned herring because fermentation produces an extremely concentrated aroma and a distinctly salty, fermented flavor. Anyone researching the product should understand the handling requirements associated with opening a pressurized fermented-fish container.
- Confirm whether the container contains fillets or whole fish, because both versions of Röda Ulven surströmming exist.
- Review the expiration or production information printed on the actual can.
- Consider whether suitable refrigerated storage is available.
- Account for the strong odor when selecting a location for opening and serving.
- Inspect the package for leakage or significant physical damage before handling.
- People with fish allergies should avoid the product.
- Do not assume that identifiers assigned to other Röda Ulven can sizes or versions apply to this specific product.
Customer Feedback Summary
This section summarizes recurring themes in publicly available consumer discussions and reviews. These observations are subjective customer experiences and should not be interpreted as verified technical specifications.
Positive feedback commonly centers on the product’s connection to traditional Swedish surströmming and the convenience of the fillet format. Consumers familiar with fermented fish sometimes describe Röda Ulven as having the characteristic salty and strongly fermented flavor expected from traditional surströmming. Fillets are also viewed by some users as easier to portion because less preparation is required than with whole fish.
The most frequently reported limitation is the extremely strong odor released when the container is opened. Reactions to the flavor are highly divided, particularly among people tasting surströmming for the first time. Consumers also mention the need to handle swollen cans carefully and commonly prefer opening the product outdoors. Texture, fermentation intensity, and the condition of the fish can vary with age and storage history.
