Doing This Can Help Preserve the Flavor of Your Coffee
Nothing communicates “Wake up” more than the aroma of freshly brewed coffee. However, if you want to preserve its flavour, you should not leave it on the hot plate for hours.
Turning off your drip coffee maker as soon as brewing is complete will preserve the flavour.
The majority of drip coffee makers are equipped with built-in hot plates that keep the glass carafe warm for two to four hours. This allows you time to consume multiple fresh cups, which is convenient; however, there is a disadvantage: the hot plate can alter the flavour of your coffee.
In the same way that reheating coffee or placing it on a warmer can alter its volatile compounds, the hot plate of a coffee maker can also alter the flavour, and not for the better. In essence, the hot plate will continue to “cook” your coffee and may cause it to taste more bitter and acidic, neither of which are particularly appetising flavours.
What is the answer? If you can switch to a coffeemaker with a thermal carafe, you should do so. In lieu of continuously heating via a hot plate, a thermal carafe will simply insulate your hot brewed coffee without altering its flavour. If this is not possible, however, it may be time to invest in a quality thermos and simply pour from it during the morning hours.
If you believe that your coffee tastes bitter, it may be your coffee maker.
