Keurig 2.0 Brewing System
Keurig rolled out the Keurig 2.0 brewing system in 2014, offering coffee lovers a unique way of enjoying their drinks.
The coffee is silkier, richer, and has a more pronounced flavor and aroma profile than coffee made with the Keurig 1.0 system.
Brewing coffee is also faster, allowing users to enjoy a cup, mug, or a full carafe without leaving the machine for the chair or breakfast table.
The Keurig 2.0 system uses a state-of-the-art digital rights management technology, scanning each K-Cup, K-Mug, and K-Carafe coffee pod for a unique code before initiating the brewing process.
Without the code, the machine will refuse to brew.
K-Cup and Ground Coffee Compatibility
One exciting feature of the Keurig K400 is its three K-coffee pod product lines: K-Cup, K-Mug, and K-Carafe.
Each coffee pod variant can accommodate at least three coffee brew sizes.
The K-Cup provides 4-ounce, 6-ounce, 8-ounce, and 10-ounce drinks, while the K-Mug variant can deliver 10-ounce, 12-ounce, 14-ounce, and 16-ounce beverages.
The K-Carafe coffee pod is excellent for making coffee for a small group, delivering 22 ounces, 22 ounces, or 30 ounces.
The K400’s My K-Cup refillable coffee pod more than compensates for the coffee machine’s restrictive DRM technology.
One can fill the My K-Cup with ground coffee, chocolate powder, or tea and use the machine to deliver an exciting beverage.
Temperature and Brew Strength Controls
Unlike other Keurig coffee machines, the K400 has brew-strength and temperature controls.
It is the perfect solution for customizing one’s drinks, allowing coffee lovers to enjoy their favorite beverages with a stronger flavor and higher temperature.
People love the Keurig K400’s digital controls in a bright and colorful 2.4-inch touchscreen display.
There are no knobs to turn or switches to flip.
The touchscreen is responsive, and the screen layout is uncluttered, making menu navigation and settings selection a breeze.
One can also customize the display’s wallpaper, adding a touch of elegance to the kitchen or any room.
Water Reservoir and Drip Tray
The Keurig K400’s water reservoir is bigger than other Keurig products with a 70-ounce capacity.
Only the Keurig K500’s water reservoir is larger at 80 ounces.
The water tank provides more than two servings of carafe coffee, allowing small offices to enjoy delicious coffee during meetings and other gatherings.
The drip tray is removable, enabling users to slide the Keurig Carafe or a tall travel mug under the coffee spout.
Who Is It For?
The Keurig 400 is a coffee-making workhorse in the home or the office, serving fantastic coffee for one or a group of caffeine addicts.
Its size is not sufficiently large to occupy a countertop, allowing anyone to place the coffee machine on a stable surface.
This coffee machine is perfect for loyal Keurig fans because it has a revolutionary brewing system guaranteeing rich and flavorful drinks one can tweak to the desired temperature and strength.
The Keurig K400 is an outstanding compact coffee machine for anyone who does not mind limiting his K-Cup pod selection to licensed pods only.
The Keurig K400 coffee machine is not for people with an extensive collection of unlicensed, non-Keurig coffee pods.
Other Keurig coffee machines with the Keurig 2.0 brewing system cannot accommodate other coffee pod brands, limiting one’s selection of coffee flavors and styles.
Although Keurig no longer manufactures the K400, the coffee machine still enjoys a substantial following in e-commerce platforms and online retailers.
Its DRM pod-scanning technology might have spelled the early demise of the Keurig 2.0 system, but one cannot ignore the technology’s coffee-making performance.
The Keurig 400 remains a sensible choice for small offices and ordinary families who cannot get enough of Keurig’s unique K-Cup coffee pod styles and flavors.
What is the difference between the Keurig K400 and the K500?
One can think of the Keurig K500 as a more updated version of the K400.
It has 10 ounces more water capacity, 0.4 inches greater display, and 2 ounces more maximum K-Cup size than the Keurig K400.
The K500 also has a Hot Water mode and a water tank nightlight the K400 does not have.
What is the advantage of the Keurig K400 over the K300?
The only advantages the Keurig K400 has over the K300 are a bigger water reservoir (70 ounces vs. 60 ounces) and a color touchscreen display (the K300 only has a grayscale display).
What is the difference between the Keurig K400, K425, K450, and K475?
All Keurig K400-series coffee machines have the same technological features, design attributes, and coffee-making performance.
They only differ in product inclusions and physical dimensions.
For example, the K425 comes with a carafe and measures 15.5 x 16 x 12.5 inches.
The K450 adds a K-Carafe and K-Cup variety pack to the carafe and the coffee machine and measures 18.75 x 16 x 13 inches.
On the other hand, the Keurig K475 has all the product inclusions of a K450 but with an additional water filter starter kit.
It also measures 10.43 x 13.63 x 13.45 inches.
The Keurig K400 does not have any of these inclusions, only the coffee machine.
