Depending on the model, Nespresso machines brew espresso at around 78 – 86 degrees F, an ideal temperature range in which the liquid will properly extract without getting burned.

However, running hot water through the machine before pulling an espresso shot can make for an even smoother and sweeter brew and eliminate any excess bitterness.

Performing this step will help remove excess grounds, limescale, and any other lingering debris from inside the Nespresso machine while heating it to optimal temperatures.

To start, fill the water reservoir with fresh water, remove any pods from the chamber, and hit the button as many times as your model requires to let the hot water flow through it.

Be sure to put an empty cup on the cup support to catch the excess water. Once done, you can brew your shot of espresso as usual for a drink with better flavor and texture.
