Watching this video I learned about the Rosa Brothers Milk Company, a company that have innovated quite significantly across the dairy business supply chain system. At Rosa Brothers Milk Company, milk is processed at the farm and packaged in refillable glass bottles. The milk is then distributed to and sold at farmers' markets / stores / cafes / coffee shops / grocery outlets etc.
At Stadtmilch I learned that milk is processed directly on the farm Längimoos in Rüschlikon near Zürich. I also found out that milk is then distributed to and sold in glass bottles at Tritt-Käse in Markthalle, and that customers do some of the work themselves by filling glass bottles with milk from a machine. To see how it works, watch the short video below.
