What is the Ninja CP307 Hot and Cold Brewed System?
The Ninja CP307 Hot and Cold Brewed System is a multi-style drip coffee maker that handles hot coffee, iced coffee, cold brew, and tea from a single countertop machine.
Ninja builds it around a 50-ounce double-walled stainless steel thermal carafe and a 1.48-litre water reservoir. It includes a pre-infusion cycle on select brew styles, a step most basic drip machines skip.
Six serving sizes run from a single cup up to a full carafe, and five brew styles cover the range from standard filtered coffee through cold brew concentrate. Separate baskets and permanent filters handle both coffee and loose or bagged tea.
Ninja CP307 Hot and Cold Brewed System brew quality: does it hit the right temperature?
Ninja does not publish a brew temperature for the CP307, and it is not on the Specialty Coffee Association's list of certified home brewers, so the case for its cup rests on the pre-infusion cycle and the thermal carafe.
Some retail listings describe the CP307 as SCA certified. The SCA's own list of certified home brewers does not include it, so this review does not count it. SCA certification is the one independent test of a drip brewer's water temperature and saturation, and if that test matters to you, the Bonavita 8-Cup and the OXO Brew 9-Cup are drip makers that passed it.
The pre-infusion cycle adds time before the main brew begins, allowing CO2 to escape from fresh-roasted grounds. The bloom time varies by brew style. This step can improve clarity and sweetness in the cup, though the practical effect depends on how fresh the coffee is.
- No brew temperature is published and the CP307 is not on the SCA's certified list, so its temperature control is unverified.
- Pre-infusion is present but the bloom duration varies by brew style, so the benefit is not identical across every setting.
- The machine runs at 1500 watts, which supports the heat recovery needed to maintain temperature through a full 10-cup brew.
- Cold brew is brewed, not steeped overnight, so the result is concentrate produced by the machine rather than a passive room-temperature process.
What you can brew with it
The CP307 covers hot drip coffee, iced coffee, cold brew concentrate, and both loose-leaf and bagged tea, all from one machine with one water reservoir.
Five brew styles give meaningful variation. Classic and Rich adjust extraction intensity. Over Ice concentrates the brew to account for dilution from ice. Cold Brew produces concentrate. Specialty targets single-cup formats at higher strength, which suits milk-based drinks.
Tea drinkers get a dedicated basket and permanent filter, so the machine does not need reconfiguring between coffee and tea sessions. Six serving sizes, from a single cup to a 50-ounce carafe, cover solo mornings and group settings without separate hardware.
- Cold brew comes out as concentrate, not a full-strength ready-to-drink cup, so expect to dilute it before serving.
- The Specialty setting works well for milk-based drinks because it brews a stronger single-serving concentrate.
- There is no espresso function. Pressure-based extraction is not part of what this machine does.
- Tea brewing uses a separate dedicated basket, which keeps coffee and tea flavors from crossing between sessions.
Living with it, day to day
Day to day, the CP307 is low-maintenance by drip-machine standards, with most removable parts going to the top rack of a dishwasher and a thermal carafe that skips the warming plate entirely.
The brew-through lid, both permanent filters, removable filter holders, water reservoir, flip-top lid, frother whisk, and scoop are all top-rack dishwasher safe. That covers nearly every part that contacts coffee or tea on a daily basis.
The thermal carafe is the main exception. It is hand-wash only. The 60-minute auto shut-off and programmable timer reduce the number of decisions required each morning, and permanent filters remove the need to stock paper filters.
- The thermal carafe requires hand-washing every day, which is the one routine task the dishwasher cannot absorb.
- Both permanent filters are dishwasher safe, so the daily rinse can go straight into the machine's next cycle.
- The programmable timer allows the reservoir to be filled the night before and the machine to start before the first person is awake.
- Auto shut-off at 60 minutes means the machine will not stay on all day if someone forgets to turn it off.
Ninja CP307 Hot and Cold Brewed System vs Smeg DCF02
Against the Smeg DCF02, the CP307 wins on brew versatility and carafe quality, while the DCF02 trades range for a simpler, more focused machine with a distinct visual identity.
The CP307 has a thermal carafe, pre-infusion, cold brew capability, and six serving sizes. The DCF02 uses a glass carafe with a stainless steel warming plate and offers two strength levels against five brew styles. For brewers who want more control, the gap is wide.
The DCF02 keeps things straightforward. Its glass carafe makes it easy to see how much coffee remains, and its warming plate holds temperature for up to 60 minutes. Buyers who want a simpler interface and are not interested in cold brew or tea will find it the less demanding machine.
- The CP307 holds temperature without a warming plate, so coffee does not degrade on heat over time the way it can on a glass-carafe machine.
- The DCF02 uses a glass carafe, which shows the coffee level at a glance without opening anything.
- The CP307 adds cold brew, iced coffee, and tea brewing. The DCF02 is a hot-coffee-only machine.
- Both carry a one-year warranty and a 10-cup capacity, and both include permanent filters, so those factors do not separate them.
Ninja CP307 vs Ninja Hot & Iced XL CM371
If cold brew is the draw, the Ninja Hot & Iced XL Coffee Maker CM371 makes it in as little as 10 minutes, alongside Classic, Rich and Over Ice, in eight sizes up to a 12-cup carafe, with no pods involved.
Ninja CP307 vs Mr. Coffee Perfect Brew
The Mr. Coffee Perfect Brew Hot and Cold Brew System covers the same ground, hot coffee, cold brew and tea, with a 10-minute express cold brew and an 8-cup glass carafe on a warming plate rather than the CP307's thermal carafe.
Is the Ninja CP307 Hot and Cold Brewed System worth it?
Without a published US retail price, the CP307 is worth buying if the current street price sits at or below what comparable thermal-carafe drip machines cost.
The feature set is genuinely broad. Pre-infusion, a thermal carafe, cold brew, tea brewing, and six serving sizes in one machine is a strong list. Competing brewers that match even three of those points tend to cost more than basic drip machines.
The one-year warranty is the main reservation. A machine with this many brew modes and a motorized cold-brew cycle carries more mechanical complexity than a standard drip brewer. Check the street price at the time of purchase, compare it against machines like the Technivorm Moccamaster or OXO Brew, and buy if the gap is reasonable.
Who should buy it (and who should not)
The CP307 suits households that want one machine to cover multiple brew styles, and it is a poor fit for anyone who wants simplicity or a dedicated espresso capability.
The ideal buyer makes hot coffee most mornings, occasionally wants iced coffee or cold brew, and shares a kitchen with someone who drinks tea. Six serving sizes also make it practical for households where one person wants a single cup and another wants a full carafe.
Anyone who only ever brews a pot of drip coffee is paying for features they will never use. And anyone whose priority is espresso or pressure-based extraction needs a different category of machine entirely.
Buy it if
- You want hot coffee, iced coffee, cold brew, and tea from one machine without buying separate appliances.
- Your household includes people who drink different amounts at different times of day.
- You want a thermal carafe rather than coffee sitting on a warming plate.
Skip it if
- You only brew a standard pot of drip coffee and have no interest in cold brew or tea.
- Espresso or any pressure-based extraction is your primary reason for buying a coffee machine.
- You want a machine with a longer warranty or a glass carafe you can see into easily.
Frequently Asked Questions
Is the Ninja CP307 Hot and Cold Brewed System good for espresso?
No. The CP307 is a drip brewer. It uses gravity and hot water to brew coffee, not pressure. The Specialty setting brews a stronger concentrate suited to milk-based drinks, but it is not espresso and does not replicate the pressure extraction that defines espresso. Buyers who need espresso should look at a dedicated espresso machine.
Is the Ninja CP307 Hot and Cold Brewed System dishwasher safe?
Most removable parts are top-rack dishwasher safe, including the brew-through lid, permanent coffee and tea filters, filter holders, water reservoir, flip-top lid, frother whisk, and scoop. The thermal carafe is the main exception and must be washed by hand. Check that the carafe gets a proper daily rinse to avoid coffee oil buildup.
How many cups does the Ninja CP307 brew?
The thermal carafe holds 50 ounces, which Ninja rates as 10 cups. Beyond the full carafe, the machine also brews single cup, XL cup, travel size, XL travel size, and half carafe, giving six size options in total. The 1.48-litre water reservoir is sized to support a full 10-cup brew without refilling mid-cycle.
Does the Ninja CP307 keep coffee hot?
Yes, through the thermal carafe rather than a warming plate. The double-walled stainless steel carafe is rated to keep coffee hot for up to two hours. There is no heating element beneath it, which means the coffee does not continue to cook after brewing. For longer holding times, a vacuum-insulated carafe will outperform any warming plate.
Can you brew tea in the Ninja CP307?
Yes. The machine includes a dedicated tea basket with its own permanent filter, separate from the coffee basket. It handles both loose-leaf and bagged tea. The brew style selection covers tea as a distinct option, so no reconfiguration of the coffee side is needed when switching between coffee and tea sessions.
Does the Ninja CP307 have a programmable timer?
Yes. The timer lets you set a brew start time in advance, which means you can fill the reservoir the night before and have coffee ready when you wake up. The machine also has a 60-minute auto shut-off. Both features are listed in Ninja's published product specifications for this model.
