Q: I love to make coffee in the morning, but I feel bad that I can never finish the pot. Typically I would adjust the ratio, but whenever I do, I either get very weak coffee or very strong. I like my mix! How can I reheat my coffee to where I don’t need to adjust anything?
A: Many of us are guilty of not being able to finish off the coffee we brew, it just something that happens. Typically, you should not reheat coffee as it will become increasingly bitter the longer you are warming it. Most coffee makers have a warming function, but will turn off after a certain amount of time.
Should you still like to reheat your leftover coffee, the best way to do it is in the microwave.
The Microwave Method
Using the microwave for your coffee is the most common method of reheating beverages. Simply pour the black coffee into a microwave-safe mug, and microwave for 30 seconds and stir. If you would like the coffee to be warmer, microwave intervals 30 second increments.
Reheating any brewed beverages runs the risk of it becoming bitter. However, if you add sugar or creamer, you may notice a stronger taste of the coffee. While some are against it, there is always an option instead of wasting the current pot to make a fresh one.
You should never coffee that has been brewed and left out! Bacteria can grow quickly in the grounds and could drip into your now cooled coffee. Always wash the pot out well, and throw the grounds away once cooled.
