When you are ready to heat your coffee before you reheat it, there are some things to know about the particular coffee bean that gives you a boost of caffeine. The taste of every bean is mostly affected by the way it’s roasted because the chemical compounds inside react with heat.
The majority of flavor remains in place at the point that your personal coffee is made, heating it will start the reaction, resulting in the flavor changing. Some people find it hardly noticeable. To others, it’s at all worth it. You’ll be able to decide for yourself.
It’s also noticeable that the wonderful smell of coffee disappears when it’s first prepared. It’s not obvious, however, what we taste is largely influenced by the scent we detect. A loss in aroma could affect the way your coffee tastes and attracts you when you drink it again.
Another thing to think about is your safety and health. If your cup of coffee is just cold you are able to warm it with no worries about the safety aspect, however, bacteria thrive in the coffee. If the coffee maker has been sitting for a long time it is best to pour it back out and start fresh.
What Is The Ideal Temperature For Coffee?
Your temperature when you consume your coffee also impacts the flavor, as it determines how slowly or quickly the flavors of your beans get extracted.
Coffee that is too hot may turn bitter while the coffee that has been had a hard time cooling down or is made from water that isn’t hot enough, will result in an uninspiring, less full-bodied taste.
Most coffee shops offer their coffee in the range of 180-185F however, the average coffee drinker will wait until the temperature cools to a cooler 150F.
If you’re steeping your coffee at home or making pour-overs, the best practice is to boil the water and let it rest for five to ten minutes prior to making your espresso. A coffee maker must be set up to warm the water in a proper manner, to begin with.
Before we begin the process of heating, here’s an additional tip we’d like to give you for those who would like to test it yourself.
There’s some debate about this, but we’ll leave it to individual preference: prior to the heating process, add a pinch of salt into your beverage. The idea is that salt can help reenergize the caffeine compounds, improve the flavor, and lessen the bitterness.
How To Easily Reheat A Coffee
If your coffee was delicious but it cooled before you were able to drink it, let’s look at some options to accomplish the job without destroying your morning coffee while doing it.
Boil Your Coffee On The Stove
If you’re planning to heat your coffee the most efficient way to do it is to keep the flavor intact the best way is to cook it up on the stove where it is possible to control the temperature more easily.
When you heat it slow it will allow those chemical processes that alter the taste are less intense. You’ll also be less likely to get burned coffee.
Pour your coffee into an unassuming spot. Heat it up at a medium to low temperature until it’s steaming yet not boiling. Pour it back into your cup and drink it!
Reheating Coffee In The Microwave
If you’re craving your coffee it’s likely that you’re not willing to wait for it to heat in a slow manner on the stove. Another option is to rely on your trusted companion microwave.
If you are able to alter the settings for heat in your microwave, then the most ideal is to nip your coffee at medium temperature for about 1 min or less. The amount of time will differ based on the coldness of your coffee and the temperature you would like for it to be.
If you’re not certain regarding the temp, begin by checking it for 20 seconds, then check the temperature. Continue for another 20 seconds if required and keep going until the coffee is perfect again.
Before pressing start making sure you pour your beverage into a microwave-safe cup if you don’t have one yet.
Can You Reheat Coffee In A Convection Oven?
Countertop convection ovens are replacing microwaves in a variety of homes over the last few years, but are you able to make coffee with one? Yes, it is possible, but it’s not practical.
A convection oven is in essence an oven. If you pour in your coffee mug when you are ready to remove it, the mug will be boiling hot.
An alternative is to heat your coffee slowly and gently as we’ve discussed previously. Then with the help of a hand protector, take the cup off to pour it into a new cup that’s safe for handling.
If not when your cup is cool enough to allow you to pour it into your cup, it will be back to cold.
Can You Reheat Coffee In A Coffee Machine?
The fact is that reheating hot coffee using a coffee maker isn’t the best idea. Many coffee makers are made to keep your coffee warm. This is great, however, when you pour the coffee back into the canister and then turn off the heating element, it’s most likely to burn to the surface of your coffee possibly damaging your pot, and ruining the taste of your cup of coffee.
The heating plate is made to hold warmth and not generate it. It’s not sufficiently hot for the heat to spread to the entire pot however, it warms only the bottom layer liquid, enough to cause damage to it.
Reheating Coffee Using Milk, Sugar, Or Cream
When you’ve already added cream or sugar or other flavors into your beverage, you’re likely to need to be cautious when warming it once more.
Dairy can be very easily curdled particularly when there’s sugar in the mix It’s also susceptible to curdling. A rapid heating process can lead to disaster, therefore, be aware of the medium or low-temperature rule.
Also, you should be certain that your coffee wasn’t stored for too long, since dairy and dairy-like products are more prone to go off more quickly than coffee.
Can You Reheat Cold Brew Coffee?
You can! Cold-brew coffee is distinct from iced coffee, and therefore it is important to differentiate between both.
Iced coffee is just a type of traditionally brewed coffee that’s which is poured over ice until it’s cool.
The cold brew is produced by steeping coffee beans that have been coarsely ground in water at room temperature for extended durations, up to 12 to 24 hours in many instances. This results in very dense coffee drinks.
There are two common and delicious methods to warm up your cold coffee:
- Warm up a cup by pouring a tiny portion of hot water in then swirling it around then throwing it away. Fill the cup about halfway with cold brew, and add boiling water that’s been sitting for five minutes.
- Prepare your cup to warm as described previously mentioned, then fill it half with cold brew, then add steamed milk. Your coffee will not be as hot and won’t keep as warm for longer than when you use hot water. Therefore, make sure to drink immediately to enjoy the best enjoyment.
Are You Able To Make Bulletproof Coffee?
You can indeed reheat bulletproof coffee. And I happen to write an entire article on it! It is available here.
Stovetop methods are perfect since butter along with the MCT oils could cause coffee to create an obnoxious discoloration in your microwave because of the oils that splash out. Pull out a small saucepan and a whisk and then heat your bulletproof coffee at a medium temperature while stirring frequently to integrate the oil into the water.
Heating Starbucks Coffee
Starbucks cup coffee explicitly advises you not to heat your coffee. This is for two reasons:
- They are not able to guarantee the quality of the coffee they reheated and, therefore, recommend against it.
- Their cups are made of a thin inner lining, which is not microwave-friendly.
- Starbucks want you to buy another coffee rather than reheating it – it makes business sense! I used to work in a Starbucks when I was 17 years old, I remember our manager always making sure we get customers to buy, not reheat!
If you need to heat to reheat your Starbucks coffee, place it in an insulated microwave-safe mug and then heat it using one of the techniques described in the previous paragraphs.
Alternative to Reheating Coffee
Drink it cold, but properly cold. Add ice to your drink and pour the cold brew at room temperature onto the frozen.
