The Breville Bambino Plus is an upgraded version of the Bambino espresso machine, with several new and improved features. Firstly, the Bambino Plus comes with a larger water reservoir, which means you can make more coffee without having to refill the machine as frequently. Another key difference between the two machines is their milk heating and texture settings. The Bambino Plus features three adjustable milk heating and texture settings, while the Bambino has only one default setting. This means that with the Bambino Plus, you have more control over the milk texturing process, allowing you to create a wider range of coffee drinks with different milk textures and temperatures. Overall, while both the Bambino and Bambino Plus are great espresso machines, the Bambino Plus offers more advanced features and customisation options that make it an ideal choice for coffee enthusiasts who want more control over their coffee brewing process.
