Mammen Mejeri A/S took over Drøsbro Dairy in 2004. This has been renovated and expanded from 2000 m² to 5000 m² with a new osteria, storage area and packing area. The history of the Drøsbro Dairy can be traced all the way back to 1887, when the Drøsbro Dairy Cooperative was established. This dairy was taken over by Mejeriselskabet Denmark (later MD foods/Arla Foods), which ran it until 1987. In May 2004, Mammen Mejeri A/S bought the dairy from Arla Foods.

Mammen Mejeri A/S has moved the production of Danablu from Katrineholm Dairy in Skørping, Northern Jutland, to the new plant in 2006. Today, Drøsbro Dairy produces 1.500 tonnes of Danablu and 4.500 tonnes of Combiwhite and salad cheese. This includes Mammens 60+ Danablu, which won the Danish National Cheese championship for the company in 2006 and 2009 – most recently at the Country Dairy Expo in Herning, Denmark.
