Today, coffee is an important part of our lives. It gives us energy when we feel tired in the morning and don’t want to get out of bed. And if you have the perfect brewer, that is the best thing in the world.
When you talk about a good coffee maker, Keurig is one of the first brands that comes to mind. Keurig coffee makers are very popular and can be found in almost every home in the U.S.
Those of us who love our Keurigs probably wouldn’t be able to make it through the day without our morning single-serve fix!
But we might not think much about how these coffee makers work. When was the last time you asked yourself how a Keurig works? The way Keurig coffee makers work is the real reason some coffee lovers love them and others hate them.
Let’s look more closely.
The Keurig coffee maker and the different things about it
Most likely, you already know what a Keurig is. This handy little device started showing up in places like lounges and doctors’ offices so that they (and others like them) could give each person their own cup of coffee. Not only was it cleaner, but since there was always hot water, someone didn’t have to keep using a standard drip machine to make pot after pot.
Not long after that, people began to put the Keurig in their homes. Because it made coffee quickly and easily, it became a popular way to make coffee. But that doesn’t mean it doesn’t have its fair share of problems.
Now, let’s take a closer look at some of the most important parts of a Keurig coffee machine.
How to understand the K-Cup?
Before figuring out how Keurig machines work, it’s important to know how K-cups work, since K-cups are what make the machines work.
From an engineering point of view, Keurig did a pretty good job of making the K-cups. The K-cup looks like a simple plastic cup with a lid from the outside.
But the K-Cup is a lot more than what meets the eye.
There is a little plastic cup and a foil lid on the outside. A small paper filter basket is attached to the top of the cup and sits inside.
Coffee grounds, tea leaves, or even hot chocolate powder rest in the paper filter, and there is a small space between the bottom of the filter and the bottom of the K-Cup.
Before the foil lid is put on, the manufacturer fills the whole cup with nitrogen to make sure it is clean. Nitrogen is used to get rid of oxygen, leaving only nitrogen in contact with the coffee grounds. This is a very important step because nitrogen is a non-reactive gas. Locking out moisture and oxygen keeps the food as fresh as possible.
Many K-cup manufacturers fill their K-cups with freshly roasted and ground coffee, but this isn’t true for all of them.
The best way to get fresher coffee is to buy K-cups from smaller roasters instead of big-box stores. Even if the grounds are stored properly, you can’t tell when the beans were roasted unless the maker tells you.
It’s also important to know that not every K-Cup is made the same way. Depending on which blend you choose, there will be a different amount of coffee. Most pods have between 9 and 12 grams, but some specialty roasters go as high as 18 grams, which would make a very strong 6-ounce cup or a very nice 12-ounce cup.
Keurig K-cups
When you use a Keurig coffee maker to make coffee, it’s a whole different experience. The K-cups, or “pods,” that the Keurig machine uses are filled with freshly ground coffee.
K-cups come in a huge number of different blends, flavors, and roasts. You save time and don’t have to do much work to make one cup of coffee from one pod. K-cups are made of good-quality plastic and have a filter layer.
The coffee stays fresh because it is wrapped in a layer of foil, which keeps moisture from ruining the flavor. Just put the K-cup in the machine, and your hot, freshly made cup of coffee is ready.
There isn’t any mess to clean up. All you have to do is pull out the used pod and put it in the trash.
Always use K-cups that Keurig has approved to make sure the performance isn’t affected.
K-cup Design
Inside the cup, there is enough ground coffee for a single serving. You’ll find the filter at the bottom. Putting the K-cup into the Keurig makes it brew. There are also many kinds of K-cups to choose from. Decaf, strong, mild, breakfast blend, and a variety of other coffees are available.
If coffee is not your thing, you can always choose something else. K-cups can hold tea, hot chocolate, chai, and a lot of other drinks. It’s also important to know that Keurig came up with a K-cup insert that can be used more than once.
This is an item that looks like a plastic tube and has a coffee filter inside. The top can be taken off. If you don’t want to buy K-cups, you can use your regular ground coffee or any other beverage grind.
K-cups vs. Coffee Pods
Many people think that K-cups and coffee pods are the same things, but they are not. The K-cup comes in a plastic container made just for the Keurig, but a coffee pod is basically just a pouch of instant coffee.
The coffee pod is made of ground coffee that is sealed in a thick filter.
They are round, flat, and can be bent. Even though they are also single-serving and come in either coffee or tea, all you have to do to make them is add hot water to a cup. Also, you can’t use them in a Keurig.
How Hot or Cold the Water Should Be?
Most Keurig coffee makers are set to a temperature of 89° Celsius (192° Fahrenheit). The temperature inside depends on many things, like the material of the cup.
If you haven’t used your Keurig machine in a while, you should always run some clean water through it so that the coffee doesn’t lose its flavor. This will warm up the coffee maker before you put the pods in and make your coffee.
Size of a Cup for Brew
On the brewer’s screen, you can choose the size of the cup. You have to choose the option for the number of cups you want to make. The new Keurig 2.0 machines can tell the difference between K-cups, mugs, and carafes.
How Does the Lid Work?
A few years ago, Keurig 2.0 came out with new technology, which could automate different parts of making coffee and also made it so that only Keurig-licensed coffee pods could be used. The K-mug and K-carafe pods were the only ones with these features (which have now been discontinued).
What does Keurig do to make coffee?
When it comes to making coffee, almost all Keurig machines work the same way. In fact, all Keurigs have a single button that lets you choose the size of the cup. The rest will be taken care of by the machine.
The Keurig system uses two needles to make your cup of coffee.
When you put the K-Cup in the Keurig and close the lid, the needles come into play. The first needle is in the lid. When you close the pod, it pokes a hole in the foil lid, letting water flow through.
The bottom of the K-Cup sits on the second needle. Here, the bottom of the K-Cup is pierced to make a hole for the brewed drink to flow through. Your coffee should end up in your cup after going through the bottom needle.
Here, though, is where the magic happens.
There is a water tank and a complex system of tubes and pipes inside the Keurig. Water flows from the water tank through the pipes and into a heating chamber, where it heats up quickly.
As long as the machine is on, Keurigs will always have a little bit of hot water in them. This is so that you always have a cup of coffee on hand and don’t have to wait for the machine to heat up more water before you can brew.
Water flows through the small needle on top of your K-Cup from the heating chamber. When you force water through the smaller needle, it builds up pressure. Even though the pressure isn’t as high as in an espresso machine, it’s still enough to get the coffee out quickly.
The hot water flows through the coffee grounds, the paper filter, and the needle at the bottom of the pot until it reaches your cup.
How much water the machine gives out depends on the size of the brew you choose. Since there is no complicated brewing process here, you can make not only brewed coffee but also hot chocolate and tea.
All of the extraction is done by pressure and temperature.
This really cool stop-motion video from Wired shows how a Keurig machine works from the inside.
Even though this seems like a simple process, there is actually a lot going on. Everything in the Keurig is controlled by a small computer that makes sure everything works the way it should.
A sensor in the water reservoir tells you and the machine if there is enough water in the reservoir. For example, if there wasn’t enough water, the heating coils could get too hot and burn out because there would be nowhere for the energy to go.
The computer also controls how much water goes into the heating chamber and the cup of coffee.
Pros of this brewing system:
- The speed at which a pod or K-cup brewer can make one cup of coffee is by far the best thing about them.
- Using hot water and pressure, coffee can be extracted quickly.
- The generic brewing system lets you make coffee, hot chocolate, and even tea.
- K-Cups are easy to use, and a sampler pack lets everyone in the house drink their own favorite coffee. The water reservoir is large enough to hold a lot of coffee before you have to refill it.
Cons of this brewing system:
- Pods are significantly more expensive than coffee grounds.
- Pods make a lot of trash.
- Coffee purists do not consider Keurig to be “real” coffee.
- Keurig machines tend to be expensive.
How to make coffee with a Keurig?
The Keurig coffee maker is great because it is simple and easy to use. A cup of coffee is very easy to make, and whether you think pods are great or terrible, you can’t argue that the Keurig coffee maker makes coffee quickly.
To start, you’ll need to put enough water in the reservoir to make at least one cup (6 ounces or more), depending on how much coffee you want to make.
Once the machine is turned on, open the pod chamber cover and put your pod inside. Press down hard on the lid to make it snap shut. This pokes a hole in the K cup and gets it ready to brew.
If your Keurig can handle it, you can now press “strong” to make a stronger cup of coffee. If not, just press the button for the size of cup you want, and the Keurig will start buzzing and whirring and give you a cup of coffee in about a minute.
Next, open the lid and take out the K-cup. Your coffee machine is now ready to make the next cup.
Keurig does offer to recycle K-cups, so you don’t have to throw them away. Instead, you can collect the K-cups and send them back to Keurig.
One shocking thing about Keurig K-Cups is that the number of K-Cups thrown away every year is enough to go around the Earth several times.
What Do You Need to Make a Tasty Cup of Coffee at Home?
You can’t always be in a hurry to stop at the nearby coffee shop for a cup of coffee. It’s not possible, and it wastes a lot of money. So, you should buy a coffee brewer that not only saves you time and money but also lets you have a cup of coffee whenever you want.
Use these easy steps to make a delicious cup of coffee.
- Choose the size of the cup and turn the machine on. The heating chamber will turn on, and the temperature of the water will start to rise until it reaches the ideal boiling point.
- When the water is at the right temperature, it starts to come out of the hose.
- Put the K-cup in the coffee maker and close it. When you close the brewer, it will first make a hole in the K cup and then another hole in the plastic layer at the bottom of the pod.
- Water flows through the pod, and coffee begins to pour into the cup.

How can you try out different things with your Keurig?
Here are some different ways to use your Keurig coffee machine.
Choose Your Type of Coffee
Once the pod is put in and the “on” button is pressed, the machine will start making coffee. If you like strong coffee, press the button in the bottom left corner of the coffee maker. When you push that button, the machine will make a stronger cup of coffee for you to enjoy in peace.
Get Some Hot Chocolate Using a Keurig Coffee Machine
In the winter, you need hot drinks to stay warm and cozy. Hot chocolate can be made in a Keurig coffee machine. K-cups come in different flavors, and all you have to do is put them in the hot chocolate pod, choose the hot chocolate option, and press the brew button.
When the brewing is done, you’ll have a cup of hot chocolate with foam on top. Keurig also has a lot of teas, and you can make some delicious teas using the same method.

How to extend the life of your Keurig?
Like any other coffee maker, there are ways to keep your Keurig machine running well and lasting a long time. To do this, make sure the following things are done at the right time:
Descaling
The Keurig coffee maker will need to be descaled every so often. The number of minerals in your water will determine how often you need to do this. To clean your coffee maker, it’s best to use bottled water or water that has been filtered.
What is the descaling process?
When there are too many minerals in the water, calcium can build up inside the brewer. This can hurt how well the brewer works. To avoid this problem, you should get into the habit of descaling the Keurig brewer every three to six months. If your water has a lot of minerals in it, you may need to do it even more often.
Keurig machines are smart, and they will tell you when they need to be descaled. The system keeps track of how much liquid goes through and tells you when it’s time to clean the scale off. It will remind you of the message, “It’s time to clean the brewer.”
If you don’t remove the scale, you will be reminded again in six weeks. It will keep coming back until you clean the scale off the brewer.
It’s easy to descale, and you don’t need any special cleaners to do it. Keurig recommends the Keurig Descaling Solution, but there are other descaling products like “Cafiza,” which is approved by Keurig, but you can save a lot of money by using something you already have in your kitchen.
You only need vinegar that has been watered down. Run the vinegar that has been diluted through the Keurig so that it goes through all the pipes and cleans everything well.
How to clean a Keurig coffee maker?
Using a Keurig machine to make coffee every day takes less time and energy, but this machine needs to be cleaned at the right times. You can clean a Keurig coffee maker with white vinegar, citric acid, or Keurig cleaning solution.
There are a few essential parts to the cleaning process:
- Most Keurig machines will notify you when they need to be descaling, so start the process as soon as you see the reminder.
- When a machine is used, it loses a little bit of its value. The best thing you can do for your machine is to keep it clean.
- Always use a soft, damp cloth to clean the outside of the machine. Don’t put the brewer under running water or wash it with it. Except for the water reservoir and the lid, all other parts can go in the dishwasher. So you can use your hands to clean the water tank and the lid.
- The K-cup holder, funnel, drip plate, and drip tray for most Keurig models can be cleaned in the dishwasher. The lid and water tank can’t go in the dishwasher, so you’ll have to clean them by hand.
- Always use filtered water or water from a bottle when making coffee in a Keurig. It will make the machine work better and last longer. Limescale builds up in the machine when hard water is used, which changes how the coffee tastes.

Taking Care of the K-cup Holder
The K-cup holder should also be cleaned. You don’t have to clean it every other day, but every so often, use warm water and soap to clean it.
The K-Cup holder receptacle needs to be cleaned regularly along with being descaled. When it’s time to do this, it’s not hard to do. First, take the whole thing out of the brewer and lift the handle to open the top.
Next, hold the top of the K-Cup holder with one hand and push the bottom of the whole thing up with the other. Push until the part comes loose.
Follow these steps to clean the K-Cup holder (some parts can go in the dishwasher):
- Funnel – The funnel is the first part to clean. To take it off, pull it until it breaks. This is one of the parts that can go in the dishwasher.
- Exit needle – The next step is to clean the exit needle on the inside. This needle is at the bottom of the K-Cup holder. If coffee grounds are blocking the exit needle, you can clean it with a paper clip or something similar (you won’t be able to go all the way through, so don’t worry). Then, put the paper clip into the K-Cup holder tube and move it around to clear out the coffee grounds and unclog the tube.
- Reinstall – Everything just needs to be put back together. Snap the funnel back into place, and put the K-cup assembly back into the brewer. Align the holder’s tabs with the opening so that the two tabs on the front are on the bottom and one tab is on top. Push on the top rim to put the piece back together, and it’s ready to use again.
Getting the Keurig Device Needle Clean
Needles need to be cleaned just as much as anything else. To clean the needles on a Keurig coffee maker, you just have to take the pack holder off the brewer and use paper clips to remove any leftover coffee from the needles.
After you have cleaned it, put the needles back together. Keurig 2.0 has its own tool for cleaning.
A quick look back at the Keurig
A man named John Sylvan came up with the idea for the Keurig. John got the idea because he was tired of drinking bad, old coffee at work or at least seeing other people drink it.
Back then, the problem was that there was no good way to make a single cup of coffee. Basically, you had to make a lot of coffee at once, and then everyone got a cup from the pot.
People who came first would get a fresh cup, and those who came later would get a used cup.
John made the single-serve Keurig machine, which was first meant to be used in offices as a commercial brewer.
Those coffee makers were plumbed, so they were directly connected to a water line and would never run out of water.
Eventually, the version for the office became so popular that people wanted a version for the home too. It took a while, but a home version was finally made available, and Keurig has been making successful coffee makers ever since.
When they came up with the Keurig 2.0 system, Keurig did make a small mistake, though. The new system was made to make sure that Keurig machines could only use pods with special barcodes.
This meant that roasters couldn’t just make their own pods without getting a license from Keurig and that many of the popular reusable K-cups would no longer work.
Keurig got a lot of bad feedback for this, so they stopped making the Keurig 2.0 system. All of the new Keurig machines use the original K-cups, so they can work with any kind of K-cup.
Because of this, many smaller coffee roasters, like Bones Coffee and Death Wish Coffee, also make K-Cups with their signature coffees.
Overall, it looks like a good choice.
John Sylvan came up with the name because he looked for the Dutch word for “excellence.” The English translation of Keurig is clean, beautiful, and classy.
What is the difference between a drip brewer and a Keurig?
Both of these machines are basically dripping brewers, and they both work by running hot water over coffee grounds. Still, there are some differences to keep in mind that can make you decide one way or the other.
Water
As was already said, the Keurig can hold a lot more water than a regular coffee maker. This lets you make more cups without having to refill the machine. The Keurig can also keep the water hot all the time.
There is also something to say about wasted water.
Some of the coffee in the pot goes to waste if it is not all used. With a Keurig, water is only used for one cup at a time, which cuts down on waste. Lastly, you can connect your Keurig to your water line so you don’t have to keep filling the tank. But that’s more common in an office.
K-cups vs. Coffee Bags
This is where a lot of disagreement starts to happen. On one hand, K-cups let you have your favorite coffee in a single mug. Also, each person can choose their own drink without having to change the pot or use other machines. They also make less of a mess.
K-cups, on the other hand, are not good for the environment. They are hard to recycle, and they pollute the environment in a lot of ways. Also, heating the plastic is thought to be bad for your health. Even though there is no BPA in K-cups, the chemicals in the material are still thought to be dangerous.
Aside from these problems, K-cups tend to cost more than a bag of coffee. The price depends a lot on the brand, but in general, it’s more expensive to keep a steady supply of cups. Not only that, but other than the Keurig insert accessory we talked about earlier, K-cups are the only coffee you can use.
The Actual Machine
We’ve already talked about the big differences between each machine, but there are still a few more things to think about.
First, the Keurig is made to withstand high pressure and hot temperatures. They also tend to be more durable and last longer than the average drip brewer.
It’s also easier to clean the Keurig. Not only does it have fewer parts, but most of them also come with a light that says “descale.” This tells you that there are too many minerals in your machine, which is making it work less well.
This happens more often in places where the water is hard. Putting vinegar through it is enough to clean it out, though.
Lastly, we’ve already said that the Keurig works much faster and is always ready to make your next cup of coffee.
Frequently asked questions
Keurig brought a cool idea to the coffee world. Keurig is easy to use, which is why it works so well in our fast-paced world.
This one-cup coffee maker is good for a lot of different people and situations. Look at the times when this machine is most useful:
1. Singles: The Keurig is a great choice if you live alone. It keeps you from having to guess how much water and coffee to put in a drip brewer for just one or two cups, and you won’t waste any water.
2. Use in the workplace: We’ve already discussed how useful a Keurig is in an office or other commercial setting. This means that both customers and employees can enjoy a fresh cup without having to wait. Even better, the single K-cups help keeps things cleaner. Like a single home, it can reduce the amount of water and other coffee supplies that go to waste.
3. People who are constantly on the go: If you and your family are constantly on the go, or if you rarely have time to make a cup of coffee in the morning before leaving, the Keurig is a good choice. It takes less than two minutes to make several cups of coffee.
4. Different tastes: If you live with a large number of people who all prefer different hot beverages, the variety of K-cups can make life easier.
The exact amount depends on the coffee’s brand and blend. Most of the time, though, there are about 2 tablespoons of coffee grounds in a K-cup. That’s about 8 to 12 grams of ground coffee or about 1 standard coffee scoop.
Most of the time, breakfast blends and light roasts are on the low end. At the high end are dark roasts and extra-bold blends. Some of these have as much as 14 grams of coffee grounds. Medium roasts are about halfway between dark and light.
Not even close. You might see a video that says you can make a latte in your Keurig by adding milk or something else. That isn’t true. It won’t work, and your machine will break. No liquids other than water and descaling solutions are meant to go through the pipes or the reservoir.
You can do one of three things if you want milk in your Keurig drinks:
1. Put it in after the coffee is done. Before putting the milk in the mug, you can use cold milk, heat it in the microwave or on the stove, or even froth it in your favorite milk frother.
2. Purchase a K-cafe, which contains everything you need to make lattes and cappuccinos with your Keurig.
3. Get K-cups that come with milk, like the Gevalia Cappuccino K-Cup Coffee Pods With Froth Packets.
Your Keurig coffee machine can do more than just make coffee. How about a cup of delicious hot chocolate?
It’s simple to do. Just put the K-Cup pack of hot chocolate in and lower the bail. Press the “Hot Cocoa/Other” button and then the flashing “Brew” button. Cocoa powder is in the K-Cup hot chocolate pack.
During the brewing process, the piston pump in the machine pushes air into the water, which breaks it down. Not only does the cocoa mix in, but it also makes that tasty foam on top. This setting can also be used to make tea, and there are many different kinds of Keurig tea to choose from.
Conclusion
The US buys more coffee than any other country. Every day, people in the United States drink 400 million cups of coffee.
If you drink a lot of coffee, you would want a nice, cheap, and effective coffee maker at home.
The Keurig is a really interesting idea, and it makes it easy to make just one cup of coffee at a time, which was not easy to do before.
Keurig coffee maker is without a doubt a good buy. It saves you time, is easy to use, and is well worth the money. If you really like coffee, this brewer will work well for you. With a Keurig coffee maker, you can make just one cup of coffee.
