BREATH is a project conceived and developed by the young designers, focuses on lacto-fermentation, a method of preservation that does not require the use of electricity and allows each part of the food to be enhanced, enhancing the flavours and reducing waste. BREATH is a three-elements System: a cap containing a valve and two silicone membranes designed to ensure that no liquids leak out, and to replace ordinary glass weights used to hold fermented food in the correct position. All the BREATH elements can be easily 3D printed.
