The best dual coffee maker is the Ninja DualBrew Pro CFP307. If you mostly brew full pots, the Cuisinart Coffee Center SS-20P1 is better.
A "dual" coffee maker, for this roundup, must brew:
- Single cups from K-Cups (and reusable K-Cups)
- At least 4 cups at a time from ground coffee
Extra features are fine, but I judged them mainly on those two jobs. I've owned a Keurig K-Duo and plenty of drip and single-serve brewers, and I researched owners' experiences of the rest. I'll also flag two popular dual machines I'd avoid.
- Best overall and best-tasting: Ninja DualBrew Pro CFP307
- Best for full pots, most durable: Cuisinart Coffee Center SS-20P1
- Cheapest I'm happy to recommend: Hamilton Beach FlexBrew 49976
Best Overall: Ninja DualBrew Pro CFP307
Ninja DualBrew Pro CFP307
The best K-Cup coffee of any dual brewer, plus great small-batch drip.

Coffee Quality: 8/10
K-Cups: as good as any K-Cup machine. Like the Keurig K-Supreme and Supreme Plus, it pierces pods with several needles for more even extraction, and its strongest setting brews for over two minutes. It also offers a 6 oz size, which is ideal for the small amount of coffee in a K-Cup; machines that start at 8 oz tend to make watery pods.
Ground coffee: good up to about half a carafe. Above roughly 37 to 40 oz, the basket can't hold enough coffee, so full pots taste watery. You can also brew single cups (about 4 to 15 oz) from grounds, which avoids weak, oversized K-Cups.
Ease of Use: 9/10
The best controls of any dual brewer. Preset sizes mean no measuring water, and every setting is labeled in plain English. More detail in my DualBrew Pro review.
Build Quality: 7/10
Good internals, plasticky outside. Sizes are accurate, it heats more consistently than other dual brewers (though it isn't SCA certified), and I found few reports of the heater fading. The frother and doors feel flimsy. The CFP301's glass carafe is fragile, and the CFP307's thermal carafe only keeps coffee hot for about an hour. Ninja's customer service gets mixed reviews.
Value: 7/10
Pricey, but fair. You get the most for your money by skipping K-Cups entirely. But if you want a dual brewer, this beats Keurig's pricier machines.
Strengths: the best coffee of any dual brewer, preset sizes, lots of brew styles including iced and a strong "Specialty" concentrate. Weaknesses: watery full carafes, flimsy parts.
Best for Full Pots: Cuisinart Coffee Center SS-20P1
Cuisinart Coffee Center SS-20P1
The only dual brewer that makes a full carafe without it tasting weak.

Coffee Quality: 7/10
K-Cups: a bit better than mid-range Keurigs like the K-Mini Plus, but not as good as the Ninja. It uses a single needle, and its Bold setting brews for about 1 minute 40 seconds. Stick to 6 to 8 oz per pod. It has no dedicated grounds basket for single cups, so use a reusable K-Cup filter for bigger mugs.
Ground coffee: the strongest point. It's the only dual brewer here whose basket holds enough coffee for a proper ratio at its full 10-cup capacity, so big pots aren't watery.
Ease of Use: 8/10
Simple and clearly labeled. You measure water for the carafe side, since it brews whatever's in that reservoir. The carafe reservoir is on the left, which some right-handed owners find awkward (as a left-hander, I'm used to worse).
Build Quality: 8/10
The most durable dual brewer. It's heavy and nothing feels flimsy. I recommend this thermal carafe version, which removes the most fragile part of most coffee makers. The weak point is the K-Cup needle, which can blunt over time, so pods sometimes need a second close to puncture. It has a three-year warranty, and Cuisinart's support is good at sending replacement parts.
Value: 7/10
Similar money to the Ninja, but it should last longer. More Cuisinart options in my best Cuisinart coffee makers.
Strengths: full carafes without watery coffee, three-year warranty, few flimsy parts, no glass to break. Weaknesses: no dedicated single-cup grounds basket, K-Cup needles can blunt, the thermal carafe can drip when pouring (the glass SS-15P1 is the cheaper alternative).
Cheapest I Can Recommend: Hamilton Beach FlexBrew 49976
Hamilton Beach FlexBrew 49976
Affordable, surprisingly reliable, and it brews single cups from grounds too.

Coffee Quality: 6/10
K-Cups: on par with lower-end Keurigs, and the Bold setting brews slowly for a stronger cup. You can also brew single cups from grounds using its included basket, so 10 to 12 oz mugs don't taste watery. Keurig dual machines can't do this as neatly; see Hamilton Beach FlexBrew vs Keurig K-Duo.
Ground coffee: decent up to about 6 cups (30 oz). Beyond that, the basket can't hold enough coffee and pots get watery.
Ease of Use: 6/10
Simple, clearly labeled buttons, and even the delay brew is easy to set. You do measure water for every brew, pods included.
Build Quality: 6/10
Not sturdy, but sturdy for the price. Handle the glass carafe and hinges with care, and expect around five years. It has fewer known faults than most budget dual brewers.
Value: 9/10
Excellent. It's far cheaper than the others, reliable, and makes decent coffee, which is more than most cheap dual brewers manage.
Strengths: better K-Cups than similarly priced combos, single cups from grounds, delay brew, very cheap. Weaknesses: watery above 30 oz, fragile glass carafe.
Two to Avoid: Keurig K-Duo and Ninja Hot & Cold
- Keurig K-Duo: overpriced and, in my experience, unreliable. Its pump weakens, so cups get smaller over time, and its carafe coffee is weak. Details in my K-Duo review.
- Ninja Hot & Cold Brewed System (CP301/CP307): not actually a K-Cup machine, but it often appears in dual-brewer lists. You pay extra for a 15-minute "cold brew" that isn't cold brew. See Ninja CP301 vs CP307.
How to Choose
Ground Coffee Brewing
Ranked best to worst for full pots: Cuisinart, Ninja, Hamilton Beach. Three things matter:
Brew time. Longer is generally better, within reason. The SCA suggests a few minutes of contact time; most dual brewers rush.
| Time per cup (strongest setting) | |
|---|---|
| Cuisinart SS-20P1 | ~1 min 40 s |
| Ninja DualBrew Pro | ~2 min 10 s |
| Hamilton Beach FlexBrew | ~1 min 20 s |
Brewing temperature. You want 195°F to 205°F throughout. Few machines manage that.
| Holds temperature well | |
|---|---|
| Cuisinart SS-20P1 | Close |
| Ninja DualBrew Pro | Best of the three |
| Hamilton Beach FlexBrew | No |
Basket size. It needs to hold enough coffee for roughly a 1:16 to 1:18 ratio at full capacity, or big pots come out weak.
| Largest batch at a good ratio | |
|---|---|
| Cuisinart SS-20P1 | Full capacity (~50 oz) |
| Ninja DualBrew Pro | ~37 to 40 oz |
| Hamilton Beach FlexBrew | ~30 oz |
K-Cup Brewing
Ranked best to worst: Ninja, Hamilton Beach, Cuisinart.
Needles. Single-needle machines tend to send water straight through the middle of the pod, leaving the rest under-extracted. Multiple needles wet the coffee more evenly.
| Top needles | |
|---|---|
| Ninja DualBrew Pro | Multiple |
| Hamilton Beach FlexBrew | One |
| Cuisinart SS-20P1 | One |
Brew time. Longer is generally better. Always use the strongest setting with K-Cups.
| Pod brew time (strongest) | |
|---|---|
| Ninja DualBrew Pro | ~2 min 20 s |
| Hamilton Beach FlexBrew | ~2 min 50 s |
| Cuisinart SS-20P1 | ~1 min 40 s |
Single cups from grounds. K-Cups get watery above 8 oz, so for bigger mugs you want a grounds option. The Ninja and Hamilton Beach have a dedicated basket; on the Cuisinart, use a reusable K-Cup filter.
Price, Lifespan and Size
The Ninja and Cuisinart are premium-priced; the Hamilton Beach costs a fraction as much. The Cuisinart should last longest. All three need a fair bit of counter space; if yours is tight, see my best under-cabinet coffee makers.
My Recommendation
The best dual coffee maker is the Ninja DualBrew Pro CFP307. If you mostly brew full pots, get the Cuisinart Coffee Center SS-20P1. On a budget, the Hamilton Beach FlexBrew is a great start.
Only need K-Cups? See my best coffee makers for K-Cups. Weighing up the brands? See Keurig vs Ninja.
