You pick up your morning coffee cup to get into your morning routine. Maybe your turned on your drip coffee maker or Keurig and you take your first sip of the day, and the damn thing’s gone cold! I’m pretty sure this is not how you want to start your day.
If only you knew how to keep coffee hot, the right way.
Let’s look into if we can actually keep our coffee warmer for longer without running the risk of drinking it like water. But first, we have some myths to crack to keep your coffee warm.
Demystifying keeping your coffee hot
Quick fixes in life isn’t worth it…
Using a hot plate
You might think using hot plates can be perfect for your coffee to heat up, but it’s not. It uses direct heat, so it will generate high temperatures that can send the coffee from horribly cold to hot. Why is this an issue? Heating up coffee on hot plates is going to overcook your coffee and distorts the flavor, making it bitter.
Can I use a candle warmer?
Candle warmers are built to warm up scented candles (who would have thought?) and you might just consider putting your coffee cup’s to heat it up?
This follows the same principle as the hot plate; it can also take the espresso from cool to warm (and probably terrible) and go down.
Just use the microwave!
Coffee is a one-time usage kind of product… Reheating reorganizes the coffee’s chemical make-up and completely ruins the flavor profile. Most things just don’t work to heat up, and coffee is one of them.
Microwaves use energy, so the temperature of your coffee will end up inconsistent. The top levels of your coffee might be hot and steamy, but everywhere else might be dry. Microwave coffee also leaves an aftertaste of burnt-coffee.
Will the coffee stay hot if you keep it in the carafe?
Oh, your French press carafe may have all the correct coffee brewing features, but it’s also a mistake to leave it there so it stays hot.
In reality, it can offer you an over-extracted cuppa that leaves your mouth with a drying effect, without all those rich coffee flavors. It’s not really how you expect your French press brew to work.
Here are 7 ways you can keep your coffee hot, the right way
1. Wrap it with a cloth
It is a challenge to keep your coffee hot when you’re on the run–you’re not always moving around with a heat source. Good news though – if you’ve got any heavy cloth around, just put it around your cup to keep it insulated.
It will not provide long-lasting warmth, but it should provide a way to keep your cup of coffee hot enough for at least one more hour. Just enough to keep you in the best coffee mood until you have an opportunity to grab another hot brew.
2. Use an actual cup sleeve
There are choices for cloth, knitted sleeves, sleeves for neoprene, and some that can even be personalized on Amazon
Put a couple of them in your car, at the house or the office, and you’re always ready to go with your brew.
3. Buy a travel mug with insulation
If you’re an enthusiastic drinker of coffee, it’s safe to assume you’ve got a favorite cup, right? If you do, I hope it’s something like one of these travel mugs that comes with a removable cover. That way, just put a lid on it, find one that matches, or pick up something with one. Not only does this simple solution keep the heat in, but also the brew’s aroma and flavors.
4. Preheat your cup before
Those who let their coffee go cold will be happy to know that you can keep your coffee warmer by preheating the cup or mug to maintain the optimal brew temperature for a longer period.
Coffee brewing fanatics know the value of preheating a carafe to ensure the temperature remains at 195F to 205F in order to bring out the coffee beans ‘ flavors effectively.
- Fill the cup with boiling water.
- Let the hot water stay for about a minute and let the heat disperse throughout the cup,
- Throw the water away when it cools down or put it back in the kettle for later use.
It’s a cool little trick and it doesn’t change the brew’s flavor at all.
5. Use a thermal mug or a tumbler
One of the most obvious ways of keeping the coffee hot is to put the coffee in a heated mug or tumbler right after making it. You can even use your thermal mugs or tumbler on some coffee machines.
These thermal mugs and tumblers are specially designed with insulating materials, such as stainless steel, plastic and silicone, and can keep your coffee hot and steamy for up to six hours.
They work best for travel since they ‘re almost unbreakable and light enough to carry around anywhere. The most dependable ones are about $20 or more, but they also guarantee to keep your coffee warm to the sip.
6. Car cup warmer
What’s worse than traffic? Sitting with a cold, bitter coffee in traffic!
Get one of the digital cup heaters you can connect into your vehicle. Most will comfortably fit the tumbler’s length or the regular take-out cup.
7. Buy these metal coffee beans
No, its not a magic trick – these metal beans are called Coffee Joulies. You can drop these in your coffee and they are built to absorb the heat and hold the temperature for longer period. Worried about eating them by accident? They’re big enough to not worry about it. Preheat them to make them more efficient (if you have the time) to hold the coffee warmer for longer.
Can I refrigerate leftover coffee?
The leftover coffee can be refrigerated. Coffee can be refrigerated in an airtight container for up to one week! Nonetheless, coffee, as most items are food and drink, is a duped to oxidation, which ensures that it goes bad pretty fast. Yeah, you don’t want coffee that’s been sitting out for more than 30 minutes as it’s likely to have lost its flavor profile and freshness by that point.

How does water temperature affect coffee?
Water temperature impacts the taste of the coffee. The oils, acids and other aromatic compounds of the coffee are extracted out of the coffee bean during the (extraction) process, resulting in a tasty cup of coffee. Brewing coffee at the right temperature involves dissolving these so-called coffee solubles at maximum strength and releasing them into the pour. You’re going to burn the coffee grounds if it’s too hot. Or cold can make your coffee flavorlessly.
