My Over Ice Brew is not cold?

The Over Ice Brew is designed to brew hot coffee over ice to lock in the flavor for rich, smooth iced coffee. Make sure your cup, travel mug, or carafe is filled all the way to the top with ice cubes. We strongly recommend ice cubes when making iced coffee. Shaved and crushed ice have different packing characteristics. Because of this, you should NOT use shaved or crushed ice as the vessel used may overflow once coffee is brewed over the ice. IMPORTANT: DO NOT use hot water in the water reservoir. We recommend cool, fresh, filtered water.

What impacts coffee brew volume?

When you make hot coffee, the coffee grounds will absorb some of the water that is brewed, resulting in slightly less brewed coffee than the water used. The more coffee you use, the more water will be absorbed. Additionally, our wider bottom carafe holds most of the coffee at the base, which helps control the temperature more evenly. If you are experiencing inconsistent brew volume, we recommend you run a clean cycle. Please refer to the How to clean & descale your Ninja Coffee Bar FAQ. See flow chart for troubleshooting.
