Nowadays a large part of the population enjoys the privilege of consuming food almost everywhere at any time. Where this comes from and what its ingredients are, seems rather secondary to the majority. Instead the factors of price, availability and convenience are important. By combining traditional food production and digital possibilities, Fermo motivates to deal with food consciously. Fermo allows the production and exchange of fermented products. On the product level, the classical fermentation pot is reinterpreted. With a smart add-on, the fermenting pot can quickly transform into a tightly sealable pot. Afterwards the product can be offered for exchange to the community via the app.
