NATURAL STONE ESPRESSO CUP This edition of the espresso cups is made of the natural stone Pannonia green, which is quarried at the foot of the Geschriebenstein. The cups are made from one piece and at the same time very resource-friendly. Pannonia Green belongs to the hard stones and is very easy to clean. In principle, the cups can also be washed in the dishwasher*, but we generally recommend hand washing with a little washing-up liquid. The material natural stone has certain material-typical peculiarities, for example, it turns dark when wet and becomes light again when it dries out. Our cups are natural and completely untreated, i.e. free of impregnation and the like. An intensifying colour tone and slight discolourations are normal. Each natural stone cup is unique in colour and structure. The cups are dimensioned in such a way that they also offer enough space for an espresso doppio and espresso macciato.
