How do you keep coffee warm without electricity?
Let’s have a look at the SOS methods in times that call for desperate measures. These are very convenient and can be used on a daily basis easily. You don’t need a lot of equipment but don’t expect for coffee to be steaming hot for hours to come!
Some of them are actually capable of keeping your elixir of life warm for long hours or the day, others are just a temporary solution when you want to keep the current cup warm until you drink it.
1. Wrap it in a scarf
Do you have a scarf or a thick piece of fabric lying around? Wrap your coffee mug in it! Layering something thick around the cup provides more isolation and enables your coffee to stay warmer for longer.
Mind you, this is only a temporary solution and it won’t keep your coffee warm for long. It’s a great short-term solution but if you’re looking for something more…practical, reliable, and long-term, read on!
2. Coffee mug with a lid (or a travel mug)
As a tricky option to keep coffee warm, consider getting a coffee mug with a lid (or one of these travel coffee mugs that keep coffee hot). There’s plenty of them that can keep hot beverages warm for a longer time! They also make a great solution on the go, if you love to bring your coffee with you when you walk to work!
You can also get a separate lid that would fit your favorite coffee mug! Make sure to get the right fit, stick it on, and there you go! Not only it will keep your coffee warm for longer, but it’ll also help to keep the aroma and the flavor inside the mug!
3. Mug Cozy
Cute and very inexpensive, these cup sleeves are another way to keep your coffee warm without electricity.
I’d suggest you warm the mug beforehand, dress it up, and pour in the coffee! There are a number of these cozies to choose from, and the best thing about them is that they’re very affordable and light. I keep a few in my bag, on my office desk, and at home. I love to have these on hand especially during the cold winter months!
Thermos is a must-have if you’re a hiker, a stroller, a traveler, and any other kind of wanderer (even if you wander to work and back). There’s nothing like a warm cup of coffee from thermos after a long hike!
A thermos can keep your coffee warm for hours and it’s very practical. It’s one of the best ways of how to keep coffee hot outside! Choose a size that fits your coffee needs and you’re good to go!
After all, these gadgets are designed with special materials such as stainless steel, silicone, and plastic and they are meant to keep the beverages hot for hours.
Some of them are a bit pricey, but then they do their job diligently and they are meant to last.
5. Preheat your mug
Preheating a carafe, a cup, and a mug is another way to keep coffee warmer for more time. At the same time, the warm container helps to bring out the flavors of the brew even more, making the coffee more enjoyable.
The ideal temperature of the carafe would be around 200 degrees F and the process is very easy. Simply fill the beaker with boiling water.
After a minute (when the carafe is all warm), remove the water and replace it with freshly brewed coffee!
6. Styrofoam cup
Not as environmentally conscious as some other options on the list, a Styrofoam cup still has a great potential of keeping your coffee warm. Much more potential than many other choices, as a matter of fact. But it’s a definite no for those who pay more attention to the environment.
7. Metal coffee beans
Coffee Joulies or metal coffee beans can keep your coffee warm without any electricity. Warm them up, pop them into your mug and you’re good to go!
These beans absorb the heat and consequently keep it for longer. You can’t swallow them (they’re the size of a soup spoon) but they are effective. Reheat them when you have the chance and keep your beverage hot for longer!
How to keep coffee warm (with electricity)?
When you have the luxury of electricity, all can be well with the world when you want to keep your coffee warm. Actually, you can keep coffee hot all day with the right gadget! Obviously, this method is much easier, but not necessarily the best or the most practical one!
In any case, see if any of these gadgets can simplify your life and make your coffee more enjoyable for longer!
1. Mug warmer
One of the easiest ways to keep coffee hot at desk, in your office, and at work is to invest in a mug warmer. You can easily plug it into different plugs (think USB cable, AC adapter, and car adapter), which makes it very practical to use pretty much anywhere.
Mug warmer is portable and it can even be used in the car, although I wouldn’t recommend it, as it’s not too stable when it has to face all the bumps in the road.
2. Immersion heater
This is another very practical gadget that can keep your coffee warm even in your car! All you have to do it place it in the coffee mug! Keep it plugged in to warm up the coffee and you don’t have gulp your hot coffee in an instant because you don’t want it getting cold!
3. Plug-in Travel mug
The best way to keep your coffee warm in your car (or anywhere else with electricity access) is a travel mug with a heater!
This baby enables you to bring it everywhere and plug it in whenever you need a little extra heat! After all, this is one of those coffee mugs that keep coffee hot and it’s very convenient for that!
4. Car heater
Let’s assume you already have a few perfect travel coffee cups and you’re seriously attached to them. Yet, you want to keep your coffee warm nonetheless.
A solution: a car heather that is actually two things in one and very practical. Not only does this gadget pretend to be a mug warmer, but it’s also a portable cup holder! It’ll easily keep your coffee safe and warm while you’re on your way to the office, day trip, or a meeting.
5. Candle warmer
Okay, I know what you’ll say: isn’t a candle warmer meant to warm the candles and bring out that amazing scent? Yes, you’re absolutely right! But! I’ve done some browsing and digging and I came to realize that many candle warmers are actually promoted as coffee/tea warmers as well!
After all, why should candles get all the fun! Plus, these are sometimes a bit cheaper than the mug warmer and can be used in the same way.
How not to keep your coffee hot
Now that we’ve got the first part covered, let’s have a look at what not to do in order to keep your coffee warm. As an avid coffee drinker, I understand the desperate measures we’d go to just to keep that thing hot and ready to sip at all times of the day.
Well, as we were able to see, there are effective ways to do it. But there are ineffective ways as well and these might lead to a bitter, overheated, or stale-flavored coffee.
The first method is the famous and all-time lifesaving machine, known as the microwave. I absolutely hate microwave-heated coffee. Yes, it’s very practical. Yes, it’s ridiculously easy to use and it does the job quickly!
But! But! Microwave can warm up the coffee unevenly (even though you can always stir it with a spoon to equally distribute the heat) and the coffee that comes out often tastes burnt, bitter, or even stale. It’s up to you, but I really wouldn’t!
Another thing that can keep your coffee hot is the electric French press beaker. Yes, it’s all very convenient. Still, the longer you leave your coffee with the grounds in there, the more bitter it turns. It’s not what you really want to drink in the end.
Q&A on how to keep coffee warm without electricity (and other queries)
Here’s a list of most common questions I found regarding the question of how to keep coffee warm (without electricity). I hope some of these will answer your own queries and help you improve your coffee issues soon and effectively!
How long can brewed coffee sit?
There are different opinions online when you dig around for this answer. Here’s what I came up with:
Coffee oxidizes, just like apples. It loses a lot of the flavor and aroma if it’s left out for too long.
- Drink it within the first hour or two after you brewed it
- Remove it from the heat source to prevent further oxidization
- Keep it in the fridge to preserve its flavor (I know this beats the point of keeping coffee warm)
- Coffee with milk should be drank fresh. I wouldn’t intentionally store it for longer than necessary
- An airtight thermos is the best way to preserve the heat and the flavor of the brewed coffee (even though the coffee still continues to oxidize after brewing)
If you notice any hint of chocolate in the coffee aroma after it’s been sitting on your counter for hours (or days even), the coffee has probably gone bad. It’s not the best idea to make a ton of coffee and store it for later in the fridge; it can soak in the flavors of all things forgotten in there (fish, anyone?).
So, does coffee spoil overnight? Black coffee normally lasts a few days if kept in the fridge. I wouldn’t, however, count on any other type of coffee to last more than a day in the fridge. It’ll be funky or completely undrinkable.
The best way to make great coffee is to make it fresh!
How long does coffee stay hot in a carafe?
You can use a thermal carafe, which will keep your coffee warm for hours. How many hours depends on each carafe, make sure to read the descriptions that come with it. Some claim they keep hot beverages for 12 hours, some claim to do more, others less.
Still, I’m not sure you actually want to drink your coffee after 10 hours after you’ve originally brewed it, so anything that promises to keep it warm for a few hours is an excellent gadget!
How do I keep my French press warm?
There’s no real need to keep your French press warm. The thing is, you should forget all about how to keep cafetiere coffee hot. It’s made to be enjoyed the moment it’s ready, and not within the next few hours (read more about French press coffee HERE).
The coffee turns bitter if left in there for too long. You have to decant it for the best flavor and to avoid any unpleasant or extra strong tastes. While some people suggest wrapping French press carafe into a towel to keep it warm for longer, I’d advise you to do one of the following:
- Pour the coffee into a thermos and keep it warm there
- Keep coffee in a double-wall cup
- Use any of the 12 methods I’ve already listed above
Can I drink a day old coffee?
Yes, you can. Many cold-brew methods suggest you leave coffee in the fridge overnight, or at least 12 hours. That means you’ll be drinking 1 day old coffee! Black coffee normally doesn’t spoil overnight, but keep it in the fridge if you want to store it.
Still, unless you’re making a cold-brew coffee, I don’t recommend keeping the coffee around for more than a few hours. The taste next day will not even closely resemble the fresh brew.
There is a difference between a hot brew and a cold brew! When using hot water, the coffee brews faster, is ready faster, and oxidizes faster. When making cold brew, the coffee takes its time to brew; it’s not about the temperature, it’s about the time it takes to be ready. It doesn’t taste bitter but still keeps the tasty flavor of the coffee!
Last words of wisdom on how to keep your coffee warm
There are ways to keep your coffee hot with and without electricity. You don’t need a huge investment to keep your coffee warm and make you happy at the same time! Luckily you can choose from a wide variety of gadgets; with some testing, you’ll find out what suits your needs best!
My personal favorites are a travel coffee mug and a thermos. These can keep my favorite beverage hot long enough for my taste. Still, make sure not to overdo it! Coffee turns bitter and stale if you let it sit out for too long and warming it up too often.
The ideal method is to make it fresh! If that’s a no-go, go for something that compromises the taste the least!
In any case, I wish you happy caffeinating! Let me know what’s your favorite method of keeping your coffee warm!
