The Ninja Hot & Cold Brewed System automatically knows which filter holder has been placed in the brew basket. The control panel will change between Coffee & Tea settings depending on which filter holder is inserted into the brew basket.

Specialty always yields 4 oz. of coffee and 6 oz. of tea (with the exception of Green tea, which yields 2 oz.

The clean cycle takes approximately 60 minutes.

The glass carafe, brew-through lid, coffee and tea permanent filters, removable filter holders, water reservoir, flip-top lid, frother whisk, and scoop are top-rack dishwasher safe.

The brew basket is designed to fit a #4 cone paper filter in the COFFEE filter holder. If using a paper filter, first ensure the permanent filter is removed from the filter holder.

TEA filter holder is denoted by the green handle with the tea leaf icon.

The CLEAN button will illuminate when a cleaning cycle is recommended for your unit, as calcium scale buildup could be affecting the flavor of your coffee or tea.

1. Pour milk into cup, until it is about 1/3 full. (Use more or less milk depending on your preference.) Microwave for 45 to 60 seconds for hot milk

2. Move the frother into the ready position by swinging the arm toward the front.

3. Hold the cup under the frother and submerge the whisk just below the surface of the milk. This allows air to fold into the milk for the frothiest results.

4. Press and hold the frothing button for 30 to 45 seconds.

5. You can easily remove the frother whisk by twisting it clockwise. To avoid spills, keep your cup below the whisk and carry it to your sink or dishwasher for cleaning.

Clean the frother whisk after each use. Hand-wash thoroughly or place on top rack of dishwasher.

The Intelligent Warming Plate will automatically turn on during a Half or Full Carafe size of Classic or Rich Brew. The Intelligent Warming Plate will adjust the heat it produces to avoid burning the coffee over time.

No. However, a medium grind is recommended.

We do not recommend adding water to the water reservoir while the system is in use.

Only add water if the clock displays the "Add" and "Wtr" messages during your brew. Add water to the reservoir, then press the START/SELECT dial to resume the brew.

Once Specialty brew has started, you cannot change brew settings. For all other brews, you may select a different brew size, style, or tea type within 5 seconds. Results vary, depending upon the status of the current brew cycle.

For optimal brewing performance, use whole ice cubes when brewing Over Ice or Cold Brew.

Yes, you can use tea bags in the Tea filter holder. Arrange the strings so they hang outside the brew basket.

Both Coffee and Tea filter holders are specifically designed for optimal brewing. The system will detect if the Coffee or Tea filter holder is inserted when the brew basket is closed, and will brew accordingly.

If you place tea in your Coffee filter holder, it will not steep properly. Placing coffee in your Tea filter holder will result in your coffee going through the steeping process, and it will be brewed at incorrect temperatures.

No, you can place whole tea bags into the Tea filter holder.

For Classic, Rich, Over Ice and Specialty, use the same amount of coffee or tea for each size selected. Each brew type is designed to make the strength you need using the measurements denoted on the Ninja Smart Scoop.

The only exception is Cold Brew Coffee, which will require one extra scoop.

Yes, we recommend using the brew-through lid as it helps maintain the carafe temperature, and to deliver optimal flavor. If the lid is not used, or is not properly in place, heat could escape from the carafe, causing the coffee to cool rapidly.

Yes, use the Tea permanent filter when using tea bags. You may remove the Tea permanent filter if more space is needed in the brew basket for the tea bags.

This brewer is designed to brew coffee grounds only. DO NOT insert pods or K-Cups* into the brew basket.

Yes, the Ninja glass and thermal carafes were specially designed for both hot and Over Ice coffee and tea. When making Over Ice or Cold Brew in the carafe, fill it to the top with ice cubes and let your Ninja Hot & Cold Brewed System do the rest.

Yes. After one hour of inactivity, the system will power off.

A medium grind coffee is recommended.

The brew basket is designed to fit a #4 cone paper filter.

Ensure your cup, travel mug, or carafe is filled all the way to the top with ice cubes before brewing. Your Ninja Hot & Cold Brewed System will brew at elevated temperatures to lock in the best flavor, then the ice will cool the brewed coffee or tea to the perfect temperature.

The Ninja Smart Scoop takes the guesswork out of measuring. One side of our scoop is used for coffee and the other for tea. COFFEE measurements are on top, and TEA measurements on the bottom. The numbers beside the icons show the number of scoops recommended for each brew size.

COFFEE (on TOP): Use the LARGE scoop for Half Carafe, Full Carafe, or a Specialty coffee; use the SMALL scoop for all other coffee sizes.

TEA (on the BOTTOM, in GREEN): Use the LARGE scoop for Specialty tea; use the SMALL scoop for all other tea sizes.

To avoid flavor crossing, Ninja designed one filter holder to be used exclusively for coffee, and another one to be used only for tea. The Coffee filter holder has the orange handle and coffee bean icon. The Tea filter holder has the green handle and tea leaf icon.

Cold Brew coffee is stronger, richer and more caffeinated, which requires the additional scoop.

An extra scoop is not needed for Cold Brew tea as it is lighter, sweeter, and more chuggable.

No size selection is necessary as Specialty brew delivers a specific amount of concentrated coffee and tea. Specialty brew delivers approximately 4 oz. of coffee, or 6 oz. of tea (with the exception of Green tea, which yields 2 oz.)

Cold Brew is a slow extraction process that brews at an accelerated lower temperature. Because it is brewing at a lower temperature, the brew takes longer to completely extract the flavor.

The Specialty Green tea setting is designed for Matcha and will get yield 2 oz. of tea. The other tea type options (Herbal, Black, Oolong, White) will yield 6 oz.

Depending on your settings, your brew time will vary from around 4 minutes to 18 minutes. The control panel will indicate brew status.

For milder coffee, use the Classic brew setting, use lighter roast beans, or use a paper filter rather than the permanent filter. If you want an even milder flavor, you can use less coffee in the brew basket.

For milder tea, use the Classic brew setting, or use less tea in the brew basket. For milder tea, use the Classic brew setting, or use less tea in the brew basket.

For stronger coffee, use the Rich brew setting, try darker roast beans, or use the Coffee permanent filter rather than a paper filter. If you want an even bolder flavor, you can add more coffee grounds to the brew basket. Additional grounds do absorb liquid, so you will have a smaller, more concentrated cup of coffee.

For stronger tea, use the Rich brew setting, or add more tea to the brew basket. For stronger tea, use the Rich brew setting, or add more tea to the brew basket.

Green tea is delicate, and therefore requires a lower brewing temperature (about 170F-175F). If brewed with water that is too hot, it becomes bitter. If you would like your green tea stronger, we recommend using the Rich setting, which results in a stronger taste.

When hot tea comes in contact with ice, antioxidants bind together and create a cloudy appearance. This is harmless, and indicates that the tea is fresh and high quality. The following tips may improve clarity:

1) Use filtered or spring water.

2) Use high-quality loose-leaf tea that isn't powdery.

3) If your tea leaves are small and dense, try using a little less of them.

Different brews require different blooming times for coffee and steep times for tea. The system knows how long and at what temperature to brew to deliver an optimal cup of coffee or tea.

Use the Herbal tea setting for Rooibos and the Black tea setting for Pu'erh.

The water reservoir markings are minimum fill lines that indicate the amount of water needed for that brew size. However, all brew styles use different amounts of water to create the proper flavor and concentration, so occasionally some water may remain in the reservoir.

Yes. While we recommend dairy milk for best performance, you can froth almond milk or soy milk. For better results, use soy milk heated.

Our integrated frother is capable of transforming hot or cold milk into a silky microfoam. For hot froth, the milk will need to either be preheated in the microwave for 45 to 60 seconds or simmered on a stovetop. Cold froth is made with cold milk and is an excellent addition to iced lattes or frozen blended drinks.

To avoid drips and spills, hold the cup that you frothed in below the whisk while you carry it to your sink or dishwasher for easy cleaning. The frother whisk is top-rack dishwasher safe. We prefer you to either hand wash or place it on the top rack of your dishwasher. We do not recommend placing soapy water in your cup and cleaning the frother while still attached.

When frothing during brewing, reach across top of the brewer. Steam is released from the top of the brewer and can result in a steam burn. reach across top of the brewer. Steam is released from the top of the brewer and can result in a steam burn.

Install the whisk onto the integrated frother by pushing up the whisk and rotating it counterclockwise. There are also lock icons on the frother whisk to indicate which way to turn it to lock it in.

To remove the frother whisk, twist clockwise and pull down.

For best results and to create the most froth using hot milk, we recommend using whole milk. For cold froth, we recommend skim milk.
