The best Nespresso capsules for an Americano need to have high intensity, otherwise, the extra water added will weaken it too much to make a really good cup of coffee. For this reason, the best capsules on our list for Americanos are the Nespresso Intenso Variety Pack, which all have high intensities, plus are meant for espressos and ristrettos, so they will maintain their full, rich flavor when the hot water is added. This pack also includes five flavors, so you can mix it up every morning.
