What Is the Keurig K-Duo?
The Keurig K-Duo is designed to combine two coffee-brewing methods in one machine.
You can use K-Cup pods to make servings when you are in a hurry or use the carafe side when you want to brew several cups at once.
This dual functionality is the reason people choose the K-Duo.
Imagine you are making coffee on a weekday morning. You only want one cup so you insert a K-Cup pod. Brew your coffee. On the weekend your family is. You need several cups. Of brewing multiple individual pods you can make a carafe.
This flexibility makes the K-Duo very appealing for households with coffee drinkers.
Depending on the K-Duo model you can also get different brew sizes and additional features designed to give you more control over your coffee.
Key Features of the Keurig K-Duo
The feature of the K-Duo is its dual brewing capability.
Single-Serve Brewing
The K-Cup side gives you the convenience Keurig is known for. You can choose from a range of K-Cup flavors, roasts and brands and prepare an individual serving.
Carafe Brewing
Unlike the K-Supreme the K-Duo can brew an amount of coffee in a carafe. This is particularly useful for families, offices and entertaining guests.
Multiple Brew Sizes
Depending on the model the K-Duo offers brewing sizes allowing you to select an amount that matches your needs.
Strong Brew Function
Some K-Duo models include a Strong Brew setting. This can be useful if you like coffee with an intense flavor.
What Is the Keurig K-Supreme?
The Keurig K-Supreme is mainly designed for single-serve coffee drinkers.
Its standout feature is MultiStream Technology, which is designed to distribute water through the coffee grounds in the K-Cup evenly.
Traditional single-serve brewing systems may send water through one point. MultiStream Technology uses points of water distribution to increase contact between the water and coffee grounds.
The goal is extraction and a richer-tasting cup.
For someone who drinks one or two cups of coffee at a time the K-Supreme can be an alternative to a larger dual-purpose coffee maker.
Key Features of the Keurig K-Supreme
MultiStream Technology
MultiStream Technology is one of the differences between the K-Supreme and many traditional Keurig models.
It is designed to saturate the coffee grounds evenly potentially helping extract more flavor and aroma from the pod.
Single-Serve Convenience
The K-Supreme is built around individual cups. You don’t have to make a pot when you only want one serving.
Multiple Brew Sizes
Depending on the model you can choose between different cup sizes.
Strong Brew
The Strong Brew setting can be useful when you prefer a cup of coffee.
