Naturally matured herring

Grøntvedt Pelagic AS is the world’s largest producer of naturally marinated herring. This herring is one of our top-quality products, and we label this as “RESERVA” or “XO”.

This herring type has different size and fat content, and during the season we produce different varieties of HK (headless) :

  • Salted
  • Sugar salted
  • Spiced
  • Lightly sugar salted, “ala matjes herring”

thereafter these products are placed in barrels in storages with different temperature for maturing.

After maturing, the herring is filleted and sorted into different sizes "by grading" according to customers preferences, and thereby placed in the brine recipe and delivered “just in time”.

What makes herring from Norway so special? It begins with our cold, clear waters - the perfect environment for Herring. From our sustainable fishing practices that protect our shores, to our quality controls, put in place from fishery to fork, and of course, the delicious flavour in every bite. Every step in the process ensures the highest quality of herring.

Herring has an important place in Norwegian culture too. Norway has long, dark winter nights and herring has provided a much-needed source of vitamin D for our people. It is also a good source of protein and healthy fats, making it a healthy choice wherever you are in the world.

Please have a look at for more information about north sea herring.

The Norwegian Spring Spawning herring (NVG) stock is at a sustainable level. This is a result of a large spawning biomass and a highly functional management plan.

The North Sea herring (NSS) stock is at a sustainable level.
Herring is caught in a directed fishery by purse-seiners and trawlers and as by-catch in the industrial fishery. The Norwegian fishery is mainly by purse-seiners. The fishery is most intense in the second half of the year, aiming at the mature and spawning stock component.
