A step by step guide about how to use the NS Adapter. The NS Adapter allows the Nanopresso to use NS CAPSULES to prepare espresso. The advantage of using capsules is that the coffee is mechanically ground, measured, and tamped with a higher precision than we are capable of doing by hand. There is very little left for error, so your espresso is consistent every single time. Pods are convenient, mess free and easier to clean after use.
