In 1909, Vilhelmiina and Kaarlo Helenius founded a home bakery called "Oululainen Kotileipomo" in Lahti.

Vilhelmiina went to baking school in Oulu and, to honour the origins of her knowhow, she named their home bakery Oululainen ("coming from Oulu").

Today, Oululainen offers a wide selection of tasty bakery products to meet the taste preferences of Finns, appreciating Finnish origins and pure taste experiences.

The famous Oululainen rye breads have always been at the heart of the brand, such as Oululainen Jälkiuuni which has been baked since 1947. The Oululainen assortment also includes other extremely popular products, for instance, Reissumies, Hapankorppu and Pullava. Bought by Fazer in 1958, the century-old Oululainen is now more popular than ever, and all the Oululainen products still are baked in Finland.
