Västerbottensost is a hard cow cheese made only at Burträsk and stored at least 14 months. In a study of a traditional Swedish long-ripened cheese made with Västerbotten milk, the milk was pasteurised, set with a mesophilic starter and coagulant, cooked for several hours above 40 °C, made into 18 kg cylinders, brined to about 1.2 % salt, waxed and ripened at 10–13 °C. The paper does not name the cheese brand.
No fixed amounts recordedThe study made each batch of 18 kg cylinders from approximately 15 000 L of milk, the volume needed for full-scale production of one batch. The maker's original recipe is described by its annual report as secret.

At a glance
Västerbottensost is a hard cow cheese made only at Burträsk and stored at least 14 months. In a study of a traditional Swedish long-ripened cheese made with Västerbotten milk, the milk was pasteurised, set with a mesophilic starter and coagulant, cooked for several hours above 40 °C, made into 18 kg cylinders, brined to about 1.2 % salt, waxed and ripened at 10–13 °C. The paper does not name the cheese brand. Made in 6 steps over 14 months. The longest step, store and ripen, takes at least 14 months (Visit Umeå). In the Swedish long-ripened cheese made with Västerbotten milk, Lactococcus (dominant in the early process samples and young cheese) and Leuconostoc, which with Lactococcus dominated cheese aged 7–20 months; Lactobacillus stayed at low relative abundance does most of the fermenting.
Made only at Burträsk and ripened more than a year; in the study the starter bacteria, not lactobacilli, still dominated after 20 months of ripening.
Milk
Pasteurised cow milk from northern Sweden
Ripening
At least 14 months; an extra-aged type at least 24 months
Place
Made only in Burträsk, from a recipe said to date from 1872
In the study
A Swedish long-ripened cheese made with Västerbotten milk (the paper does not name the brand) was pasteurised at 72 °C for 15 s, cooked for several hours above 40 °C, brine-salted to about 1.2 % salt, waxed and ripened at 10–13 °C
The milk is pasteurised before cheesemaking (72 °C for 15 s in the study). In the study the wheels were brine-salted to about 1.2 % salt, waxed and ripened at 10–13 °C, and the maker stores the cheese at least 14 months before sale.
Tourism and press pages and the maker's 2022 annual report date the recipe to 1872 and a dairymaid in Burträsk, Ulrika Eleonora Lindström; no one knows exactly what happened, and the story is told as legend. The maker marked 150 years of the cheese in 2022.
