In 1955, the Migros-Genossenschafts-Bund (Migros Cooperative Association) founded the company Conserves Estavayer SA (CESA), which from 1956 canned peas, beans, pickled cucumber, spinach and jam.
[5] Over the years, CESA gradually divested itself of almost all business areas (selling to sister companies) with the exception of milk processing and changed its name to Estavayer Lait SA (ELSA) in 1998.
[10] In 2017, ELSA increased its stake in Schwyzer Milchhuus AG from 34 to 60 percent, thereby taking over the majority in the central Swiss family business founded in 1899.
SoFine Foods produces vegan meat substitute products, including the Migros Cornatur brand.
[13] Until 2019, ELSA and the Migros Aare cooperative, together with Aaremilch AG, had built a new milk bottling plant in the municipality of Diemtigen.
