It is generally stored refrigerated between 0 °C and 10 °C (in principle, it is stored in a cool place below 15 °C), but not all products are transported at the same temperature as the storage temperature when transported relative to the product. The temperature is below 0 °C. Some products have the possibility of temporarily warming up during transportation. We will refrigerate and transport the special requirements of individual products.
