Even if you have a premium coffee maker, the warming plate will only go so far in keeping your brewed coffee warm. Unfortunately, unless you’re using a thermal carafe, your fresh-brewed pot will cool down over time. While using your coffee machine for reheating coffee is not recommended, you can do it. In addition, if you add a new paper filter and coffee grounds, you’ll end with a more potent pot of coffee. Additionally, if your coffee maker has an aroma setting, you can try it for a more aromatic, flavorful cup. Read this guide, and we’ll show you how to warm up coffee in a coffee maker. Alternatively, if you want more of an espresso-type drink, check out our guide on semi-automatic coffee machines.

KEY TAKEAWAYS:

  • Remove the spent grounds and filter from the bean basket and strain the cold coffee.
  • Use a funnel to pour the old coffee into the water reservoir.
  • Add a fresh coffee filter and new coffee to the basket. Use the coffee maker brew settings for a short brewing time.

Remember, however, that running your leftover coffee back through your coffee machine could result in an unpleasant, bitter flavor. In addition, pouring your morning brew back into the water reservoir is best done in new drip coffee makers. If you must, experts recommend using a new coffee filter and fresh ground coffee when you reheat your morning cup. Keep in mind, that you’ll need to clean the machine more frequently, so it’s a good idea to learn how to stop the light from flashing after cleaning the coffee maker. On the other hand, if your coffee does not brew at all, you want to learn how to replace a thermal fuse in a coffee maker, which may resolve the issue. Alternatively, if you want to try something new, read our guide on using a Vietnamese coffee maker.

Insider Tip

This double-brewing method produces a strong type of coffee that you might want to dilute with milk.

Reheating Coffee in a Standard Coffee Maker

Tools: Coffee maker, paper filter, fresh coffee grounds, fine strainer, coffee pot, funnel

STEP 1 Remove Old Coffee Grounds and Filter

Open the filter basket and remove the used filter and coffee. Make sure the filter basket is cool before moving to the next step.

STEP 2 Add a New Filter

Place a new filter in the basket, but make sure the base is dry if you’re using a paper filter.

STEP 3 Add Fresh Ground Coffee Beans

Scoop 1-2 tablespoons of coffee into the filter and shut the basket lid.

STEP 4 Strain Cold Coffee

Use a fine strainer to remove any pre-ground coffee that slipped into the pot. The bits of coffee can stick in the coffee maker’s water lines, producing clogs.

STEP 5 Pour Cold Coffee into Water Reservoir

Use a funnel to pour the old pot of coffee into the water tank of the coffee maker. Do not use the contents of your coffee cup to fill the coffee maker.

STEP 6 Start the Coffee Machine

If your machine has advanced features, choose a short brewing time to avoid burning the coffee. Then, press the start button and let your coffee pot fill up. For added convenience, you can connect your coffee maker with a smart plug to use your voice or WiFi to control the machine.

STEP 7 Enjoy Hot Coffee

It won’t taste like an expensive coffee shop brew, but you now have a hot pot of coffee for the rest of the afternoon. For the true coffee aficionados, check out vacuum coffee makers.

Warning

If bits of coffee get in the coffee maker’s water lines, you may ruin the machine.

F.A.Q.S

Why is my coffee maker brewing cold coffee?

If your coffee is cold, your machine is most likely dirty. Run a brew cycle with only hot water and vinegar to clean the water lines in your coffee maker.


Why is my coffee maker turning off randomly?

Your machine’s hot plate will keep your coffee warm for 2-4 hours before the automatic shut-off feature takes effect.


Why is French press coffee bad for you?

French press coffee contains a substance that is known to raise cholesterol levels. This compound, called cafestol, is not found in filtered coffee.


How do I store leftover coffee?

Store your cold coffee in a mason jar and put it in the refrigerator. That said, do not add new cups of coffee to the same jar.


STAT: According to a survey from Gallup, 36% of Americans do not drink coffee. (source)
