If you want one machine for the flexibility of ground coffee and the convenience of pods, start by checking how each model handles grounds: some brew them for both a mug and a carafe, while others offer a single-serve grounds option. Manufacturer listings confirm several choices, but they do not establish a taste, reliability, or value winner.

Which dual-brew coffee maker fits your routine?
For grounds or pods with a carafe option: Keurig K-Duo Plus
The K-Duo Plus is a straightforward fit if you want to switch between a pod-brewed or grounds-brewed single cup and a grounds-brewed carafe. Keurig says it uses K-Cup pods and ground coffee to brew a cup and a carafe, and lists four sizes for each mode. Its phrase “best of both worlds” is manufacturer marketing, not evidence of a comparative test.

Keurig’s K-Duo product page also describes the broader grounds-or-K-Cup category. The K-Duo lineup combines single-cup K-Cup brewing with a carafe brewed from grounds. Keurig Dr Pepper announced an MSRP of $99 for K-Duo Essentials at launch in 2019; that is historical launch pricing, not a current price.
#1 Best Overall
- BREW BY THE CUP OR CARAFE: Brews both K-Cup pods and coffee grounds.
- MULTISTREAM TECHNOLOGY: Saturates the grounds evenly to extract full flavor and aroma in every cup, hot or cold.
- BREW OVER ICE: Adjusts temperature for maximum flavor and less ice melt for single-cup iced coffees and teas.
- STRONG BREW & EXTRA HOT FUNCTIONALITY: Brews a stronger, more intense-flavored cup and the extra hot feature brews a hotter single cup.
- MULTIPLE BREW SIZES: Brew 6, 8, 10, or 12oz single cups or 6, 8, 10, or 12-cup carafes. 12-cup glass carafe specially designed to limit dripping.
For many brew-size choices: Ninja DualBrew Pro CFP301C
The Canadian CFP301C listing supports both grounds and K-Cup pods. It specifies nine grounds sizes, from a small cup through a full carafe, and four pod sizes: 6, 8, 10, or 12 ounces. Those details make it the clearest option in this comparison when you want a range of grounds portions as well as a carafe.
The cited listing is for the Canadian model. Before buying in another country, check the regional model number and confirm which components are included; similarly named products may not have identical configurations.
Rank #2
- 3 WAYS TO BREW: Brew a single cup with a pod or coffee grounds or brew up to 12 cups using your favorite ground coffee. To brew one serving, you have the option to brew up to a 10 oz. cup with a pod or brew up to 14 oz., 7" tall travel mug with coffee grounds.
- FAST BREWING — BREW A SINGLE CUP IN ABOUT 90 SECONDS. In the morning, every second counts. Unlike 3 way coffee makers of the past, the FlexBrew Trio Coffee Maker prepares a single cup in in 90 seconds so you have more time to enjoy your coffee.
- BREW 7 SINGLE SERVINGS WITHOUT REFILLING THE 56 OZ. WATER RESERVOIR. Brew a single cup of coffee without stopping to pour water. In addition to its fast 90-second brewing, the removable water reservoir saves you time because it needs fewer refills.
- WAKE-UP READY COFFEE WITH EASY-TOUCH PROGRAMMING. When you brew coffee into the 12 cup carafe, you can wake up to hot coffee by setting up Easy-Touch programming the night before. The backlit display makes it easy to view the time and settings.
- 5 SINGLE-SERVE SIZES TO CHOOSE FROM: Customize the brewing size to your cup. Simply select 6, 8, 10, 12 or 14 oz. before you brew with ground coffee or choose 6, 8 or 10 oz. when brewing with a pod — you'll get the perfect amount in your cup.
For a two-sided setup: Hamilton Beach FlexBrew 2-Way 49950C
Hamilton Beach describes two separate workflows: the carafe side brews grounds, while the single-serve side accepts either grounds or a single-serve pack. The product page does not identify that pack as a specific pod system, so do not assume it takes K-Cup or another named capsule format without checking the exact version sold in your market.
For K-Cup, Nespresso, and grounds in a single-serve machine: Instant Dual Pod Plus
Instant lists compatibility with K-Cup pods, Nespresso capsules, and grounds used through the included reusable pod. Its product description specifies a 68-ounce water reservoir. It does not establish a conventional carafe workflow, so consider it a multi-format single-serve option rather than a replacement for a batch brewer.

What to check before choosing
- Where grounds can be used: If you want a full pot, confirm that grounds brew into a carafe. A machine that accepts grounds for one mug may not offer the same workflow for a larger batch.
- Exact pod format: K-Cup pods, Nespresso capsules, and generically described single-serve packs are not interchangeable. Look for explicit compatibility for the precise model and regional version.
- Serving sizes: Compare the listed sizes for each brewing mode, not just the number of options overall. A pod mode and a grounds mode may support different portions.
- Reservoir and countertop fit: Check capacity, footprint, and reservoir placement on the exact product listing. The specifications cited here do not provide enough verified footprint or placement details for a reliable model-to-model comparison.
- Included parts and upkeep: Confirm whether the reusable grounds pod or other required basket is included, and consult the model’s instructions for cleaning. An accessory’s fit should be verified for the exact machine.
What these listings can—and cannot—tell you
Manufacturer specifications establish that grounds-and-pod machines are a real category and document the listed compatibility and brew options. They do not provide a controlled comparison of taste, brewing speed, durability, or reliability, so this feature comparison cannot support a claim that one model performs best overall.
Prices and availability can change. Aside from Keurig Dr Pepper’s 2019 K-Duo Essentials launch MSRP of $99, the cited material does not establish current prices for these models.
