Helpful Tips for Reheating Coffee in a Microwave

Do Not Overheat the Coffee

Always ensure to adjust the heating power of your microwave to low or medium before reheating coffee. Too much heat on coffee is not good; the coffee flavour becomes too bitter for you to enjoy.

Add a Pinch of Salt to Coffee Before Reheating

To avoid the possibility of your coffee having a final bitter taste after reheating, consider adding a pinch of salt to the coffee. The salt will neutralize the bitterness in the coffee.

Do not Allow your Coffee to Stay at Room Temperature for too Long

If you intend to reheat coffee later, it is advisable to store it in the freezer until you are ready to use it again. If you have made too much coffee, consume the portion you intended to use, pour the rest on an ice tray, and store it in the freezer.

If your coffee is made of milk, it shouldn’t be allowed to stay at room temperature for more than 2 hours due to the perishable nature of milk. The longer the coffee lasts at room temperature, the more it oxidizes and loses flavour.

Consider How Long it Has Been Since the Coffee was Brewed

Coffee that has been brewed today and lasted at room temperature for more than two hours should not be reheated and consumed, especially if the coffee was made of milk.

Usual coffee without milk can be frozen for a week and still be reheated and consumed. Coffee that has been frozen longer than the mentioned time is not suitable for human consumption.

Stir the Coffee as you Microwave

Microwave the coffee for 45 seconds, then reheat it again at an interval of 10 seconds. Use a stick or wooden spoon to stir the coffee at the end of every 10-second interval. As you stir, you help distribute heat evenly through the coffee. At this point, make use of your thermometer to keep checking the warmth of the coffee before you return to the microwave for an extra 10 seconds. Refrain from overheating the coffee once the coffee’s internal temperature is at 150 degrees Fahrenheit.

Store Reheated Coffee in a Thermos

How to Reheat Coffee in MicrowaveIt is advisable not to reheat coffee more than once. For coffee to turn out the way it is, coffee beans were thoroughly roasted and ground. When these coffee bean particles are returned to the microwave, they continue burning up, giving the coffee a bitter taste.
