It takes some time for life to return to normal in Switzerland after the end of the First World War (1918). Great efforts are made to safeguard the supply of milk and milk products to consumers. 1922 – after the mandate to cultivate grains and root crops (e.g. potatoes) is lifted – the tide turns on the Swiss dairy market: the market is flooded with milk and the opportunities to sell the product deteriorate as a result, not least due to tariff increases and import restrictions by other countries. Within the space of just a few months, the milk price falls by 15 centimes to 19 centimes per litre.
