Keurig believes that the optimal temperature for brewing coffee, tea and hot cocoa is 192° F. This is the internal temperature of the water in your brewer. However, once your coffee, tea or hot cocoa is brewed, the dispensed temperature can vary greatly. In-cup temperature depends on the cup temperature and material. When brewing into an insulated container, such as a foam or paper cup, 180-185°F in-cup temperature is typically attained. In addition, dispensing into a cold ceramic mug will cool the coffee significantly. Please note that stream temperature of the first brew after turn-on or after an extended idle period can be a couple degrees cooler.
To maximize initial in-cup temperature at home, we recommend running a small cup cleansing-brew prior to brewing a K-Cup® pod, which warms both the mug and the brewer.
