Coffee is one of the most popular drinks in America, but sometimes it can be hard to get that delicious flavor without a bitter or burnt taste. The best way to reheat coffee depends on how you want to drink it – hot, cold, iced-coffee, etc. There are many different methods for reheating coffee so let’s take a look at some of them below!\

1. Reheat coffee in the microwave

People often  microwave their leftover coffee in order to reheat it quickly.  This is probably the most common way to bring your cold or room temperature coffee back to a hot drink. Some people may microwave their coffee for only 30 seconds, while others go for one minute. The key is to experiment with your own microwave!  However,  it’s important to remember that microwaves tend to  heat unevenly, so one side of your coffee may be boiling hot while the other remains cold.

2. Brew a new pot of coffee 

Making a whole new pot might seem like a hassle, but you can use the first pour to heat your mug and take advantage of the hot water from the first brew.  This will speed up the reheating process because you won’t have to heat your coffee from room temperature, it will only take 30 seconds or so for your mug to heat up.  Just remember to keep an eye on it so it doesn’t overheat!

3. Pour hot water over your coffee grounds and brew it like normal  again

Sometimes you might not feel like making a whole pot of coffee if it’s just for yourself.  You can pour hot (but not boiling) water over your cold coffee grounds and brew it as you normally would – this could make an intensely flavored cup of coffee!  Make sure to use good quality water because the minerals in your water can greatly affect the taste of your coffee.

4. Put your mug in the freezer for 15-20 minutes before adding hot liquid to it 

This is a good idea if you’re trying to bring your coffee back to a hot drink quickly and don’t want to wait for the microwave.  The cool temperature of the frozen mug will bring down the temperature of its contents without watering it down!

5. Fill up an insulated thermos with hot water, put your cup inside, and pour the water out when you’re ready to drink 

Insulated thermoses can be a great way to maintain the temperature of your coffee – just don’t leave it in too long or you might have a cup full of iced coffee!  Just fill an insulated thermos up with hot water, put your mug inside, and pour the water out when you’re ready to drink. This method is great if you want to bring your coffee on-the-go, like when it’s cold outside and you need that extra bit of warmth.

6. Add cold milk or cream (or both!) to make it taste better!

Coffee is fun to experiment with, so don’t be afraid of adding milk or cream to your coffee if you think it’s too strong.  Milk and coffee go great together and can help tone down the strength of an espresso! For even more flavor, try cold milk or cream – this will make your coffee taste like a iced latte or cold mocha, but without the need for additional iced coffee.  Just make sure to add milk before adding your hot coffee, otherwise it might curdle!

FAQs

Is it possible to reheat cold brew coffee?

Yes, it’s possible!  Cold brew coffee may lose its flavor quickly, but there are several ways to reheat cold brew without ruining the taste.  One method is to put the cold brew in the microwave and heat it for about 30 seconds at a time.  Another great way to reheat cold brew is with hot water!  Pour hot water over the coffee grounds and let it brew for a minute or so.  This is pretty similar to how you would reheat regular coffee with hot water, except you might want to go hotter since cold brew has been sitting for a while.

Is it okay to reheat coffee from the previous day?

No, it’s not recommended that you reheat coffee from the previous day.  It can taste rather bitter if you reheat old coffee because the flavor compounds begin breaking down at high temperatures.  If you’re looking for a caffeinated drink to keep you going throughout the morning, make sure to brew some fresh coffee in advance or only brew the amount you need!  Short of that, it’s best to keep your leftover coffee in a thermos if you want to save it for later.

Why does heating coffee make it bitter?

Heating coffee makes the bitter flavors in your coffee come out more than the sweeter, smoother elements.  If you need your coffee to be less bitter, brewing at lower temperatures can help or adding cream or milk to it! You’ll still get the caffeine without the overpowering taste of hot coffee.

Do all coffee roasts, dark, medium, and light, become bitter when reheated? 

Different coffee roasts may lose their flavor at different rates when heated up.  Light-roasted coffees are known for losing their flavor quickly, so it’s best to drink them while they’re still hot!  Medium roasted coffee is known for keeping its flavor pretty well when reheated, so feel free to reheat your medium roasted coffee as much as you want! Dark roasted coffee may lose its flavor the quickest when reheated, but this depends on how dark your roast is.  If you have extra dark roast, it might be best to drink it while it’s still hot.

Is it true that heating coffee destroys caffeine?

Heating coffee does not necessarily destroy the caffeine in your drink.  When you heat up your coffee, the water will begin to dissolve some of the chemical elements in it – but it won’t cause all of them to break down!  Just remember that prolonged exposure to high temperatures can damage flavor compounds which are essential for a good tasting brew.
