The Nespresso D120 and D121 are extremely popular with espresso drinkers. In order to make espresso with these machines all you have to do is insert an espresso capsule and switch on the brewing system and you will have highly flavored espresso in a minute. Cleaning is also simple and you only have to discard the capsules after making 10-12 cups of espresso.

What are the Differences Between the D120 & D121?

Features of the D120

The D120 is a basic espresso machine with an integrated milk frother and makes espresso from Nespresso capsules. The volume is automatically controlled by the machine when you set it the first time. Cleaning up after making espresso is a breeze and you’re done once you lift the lid making the used capsule fall into the tray beneath. 

Improvements in the D121

The features in the D121 are almost the same being the newer version of the D120. The D121 has the latest Compact Brew Technology which was introduced in Nespresso machines. It also shuts off after 9 minutes if you don’t use it. The D120 has a removable cup support that is not present in the D121 which has a pivotable tray. 

The D120’s water tank holds more water at 34 ounces whereas the D121 tank holds 30 ounces only.  When you look at both you will find a narrow spout in the D121 instead of the flat, wide spout of the D120. The buttons in the D120 are placed behind whereas the D121 has them up in front. A horizontal notch on the D120 is missing in the D121.

How To Brew with a Nespresso D120 and D121

Making Espresso with the Nespresso D120 and D121 is very simple. First preheat the machine and run it the first time for hot water. This will get rid of any sediment that may have been left behind from previous use. Take an espresso capsule and insert it into the brewing chamber and press the brew button. Hot espressos will pour out from the spout. You can use the Aeroccino for frothed milk by filling it with milk and then pressing the large button in front of the frother.
