Keurig has six home brewing systems to choose from, as of 2015, which vary in size, capacity and programming levels. The systems range from the inexpensive Keurig K10 Mini-Brewer to the state-of-the-art Keurig 2.0 K550 Brewing System.
The Keurig K10 Mini-Brewer is ideal for small spaces, apartments and vacation homes. It is a no-nonsense brewer that allows the user to brew three different sizes. The Keurig K45 Elite is a step away from the K10, and differs in the fact that it has a storage space for water that can brew several cups. With the K10, water must be put into the brewer with each cup of coffee.
Another model, the Keurig 2.0 K350, differs from the lower end models in many ways. First, it can brew either K-cups or K-Carafe pods, and there are settings based on the type of drink a person wants, such as chai, hot cocoa or mocha. The Keurig 2.0 K450 is the next level up, and this brewer differs from the K350 model by having a 72-ounce water reservoir, touch screen design and programmable brewing.
The top of the line home brewer from Keurig, the K550, differs from the rest thanks to its 80-ounce water reservoir, strength control setting and night light. This brewer also allows users to get hot water from it, a feature none of the other Keurig brewers offer.
