Nanopresso NS Adapter. Are you a fan of fine coffee blends in pre-packaged capsules? Wacaco provides the perfect solution for a coffee capsule: when placed and securely screwed between the lid and body of the optionally available espresso machine of the same name, it automatically pierces the inserted Nespresso capsule. This ensures the flow of hot water through the coffee capsule during the pumping process. As a result, you can achieve an equivalent outcome with a regular capsule as you would with ground coffee or espresso. So, if you want to enjoy a small espresso on the go using a coffee capsule, not only should you consider the Nanopresso espresso machine offered by Wacaco, but also this NS Adapter!.
