Viili (Finnish viili, Swedish fil) is a yogurt-like mesophilic fermented milk that originated in the Nordic countries. This cultured milk product is the result of microbial action of lactic acid bacteria (LAB). The bacteria strains used in its production produce exopolysaccharides which gives viili a ropey, gelatinous consistency and a pleasantly mild taste resulting from lactic acid.
