For a Moka Express, it is recommended to use a medium to fine grind coffee, similar to espresso grind. This will help to achieve the best results and flavor when using a Moka pot. **

It depends on the extent of the damage to the boarding pass. If the barcode or important information is still readable, you may still be able to fly. However, if the damage is significant and the boarding pass cannot be scanned or is illegible, you may need to get a new one from the airline counter or kiosk. It's always best to check with the airline staff for guidance in such situations. **

There could be a few reasons why your Cafissimo is not allowing enough water to pass through when brewing coffee. One possibility is that the machine's water reservoir may be running low or there could be a blockage in the water line. Another reason could be that the machine's pump is not functioning properly, which could be due to a buildup of scale or debris. It's also possible that the coffee capsule you are using is clogged or not compatible with your machine. I recommend checking the water reservoir, cleaning the machine, and trying a different coffee capsule to see if that resolves the issue. If the problem persists, it may be best to contact the manufacturer for further assistance. **
