Keurig K-Duo Single Serve Coffee Maker Review

I love starting my day with a perfectly brewed coffee, courtesy of my Keurig K-Duo single serve K-Cup Pod & Carafe Coffee Maker, Black. This coffee maker is a game-changer with its ability to brew both a cup and a carafe using either ground coffee or K-Cup pods. The best part? It’s compatible with the keurig gold tone mesh filter accessory – a reusable coffee filter that elevates the brewing process. The machine is also energy-efficient, switching off automatically after 5 minutes of the last single cup brew or 2 hours after the last carafe brew. It offers the flexibility of brewing multiple sizes, from a 6, 8, 10, or 12-cup carafe and a 6, 8, 10, or a 12 oz cup. The large 60 oz. water reservoir is shared for single serve and carafe brewing, simplifying morning routines and refilling is a breeze with its removable design. Also included is a 12-cup glass carafe and a heating plate to keep my coffee hot. But what really sets this coffee maker apart is the programmable carafe auto-brew, which allows you to set it to brew a carafe up to 24 hours in advance. Add to this the pause and pour feature and smart start, it’s no wonder I’m a fan. No longer do I need to wait for the machine to heat up before selecting my cup size. The energy efficiency is the cherry on top, automatically shutting off to conserve energy.

Pros and Cons

As with any product, the Keurig K-Duo comes with its pros and cons. The key advantages include its versatility, programmable features, large water reservoir, and energy efficiency. On the downside, the lack of a digital clock and display screen might be a setback for some.


  1. Can you use a reusable pod to brew individual cups? Yes, you can use the My K-Cup® Universal Reusable Coffee Filter or similar refillable pods with the Keurig K-Duo.
  2. Does the machine have an internal heater and how long does it take to brew a pot of coffee? The Keurig K-Duo doesn’t have an internal heater that keeps water hot continuously. The average carafe brew times vary depending on the number of cups: 6 cups take 5-6 minutes, 8 cups take 6-7 minutes, 10 cups take 7-8 minutes, and 12 cups take 8-9 minutes.
  3. What are the dimensions of the K-Duo? The dimensions of the K-Duo coffee maker are approximately 12.92″H x 10.94″W x 12.76″D.
  4. What is the size of the water reservoir? The water reservoir on the Keurig K-Duo can hold about 20 oz of water.
  5. How many cups does the K-Duo actually brew with a full reservoir? Even though the water reservoir holds 60 oz, a cup in terms of coffee machines is typically measured as 5 ounces. Therefore, the K-Duo can brew up to 12 cups as per this standard measurement.
  6. Can the Keurig K-Duo remain on all the time? The K-Duo has an auto-off feature that cannot be disabled. It turns off after 5 minutes of inactivity following a single cup brew.

Tips and Tricks For Best Results

Maximizing the use of your Keurig K-Duo Single Serve Coffee Maker involves understanding and effectively utilizing its features, such as the reusable filter, the auto-off feature, and the programmable elements. Here’s some advice on each of these aspects:

Using the Reusable Filter

  1. Grind Size: For the reusable filter, use a medium grind size, similar to granulated sugar. Too fine a grind can lead to over-extraction and a bitter taste, while too coarse a grind can result in weak coffee.
  2. Amount of Coffee: The amount of coffee you use in the reusable filter depends on your preferred strength. Generally, a good starting point is about 2 tablespoons of coffee per 6-8 ounces of water. Adjust according to your taste.
  3. Cleaning: After each use, dispose of the used grounds and thoroughly rinse the filter. Periodically, it should be washed more deeply with warm, soapy water.

Understanding the Auto-Off Feature

  1. Energy Efficiency: The auto-off feature is designed to save energy. It automatically turns off the coffee maker after a set period of inactivity. This period can vary depending on the model, so check your user manual for specific details.
  2. Safety: Besides energy efficiency, this feature also adds a layer of safety, preventing the coffee maker from staying on when not in use.

Making Full Use of Programmable Elements

  1. Auto-Brew for Carafe: You can program your K-Duo to automatically brew a carafe at a certain time. This is perfect for having coffee ready when you wake up. Set the time up to 24 hours in advance by using the AUTO button.
  2. Customizing Brew Size and Strength: Take advantage of the different brew size options and the ‘strong’ brew setting for a more robust cup. Experiment with these settings to find what works best for you.
  3. Regular Programming: If you have a consistent coffee routine, use the programmable features to automate your brewing times. This saves time and ensures you always have coffee when you want it.

Additional Tips

  • Water Quality: Use fresh, cold water for the best flavor. If your tap water is hard or has a strong taste, consider using filtered or bottled water.
  • Descale Regularly: Regular descaling is crucial for maintaining the machine and ensuring the best coffee flavor. Follow the manufacturer’s instructions for descaling procedures.

Final Thoughts


The Keurig K-Duo offers great value and functionality, brewing a single cup or a full carafe of coffee exactly when you want it.
