Keurig Coffee Tastes Burnt

Keurig Making Burnt Coffee? (What To Do Next?)

Many people who own a Keurig have experienced the frustration of having a cup of coffee that tastes burnt. It can be disheartening to look forward to enjoying your morning cup of Joe, only to take a sip and find it has an unpleasant bad or bitter flavor. If you’ve ever had this problem with your Keurig, you are not alone. I was also suffering from this problem. While I was researching the problem, I found that there were several causes for this. In this article, I’ll explore all the reasons why Keurig makes burnt coffee and what you can do to fix it.

Reasons Why Keurig Makes Burnt Coffee

As a barista, I have seen several causes for why Keurig machines sometimes make burnt coffee. Here are the common causes:

Coffee Bean Oil Buildup

Over time, coffee oils can build up in the Keurig machine, leading to a rancid taste in the coffee. Regular cleaning of the machine can help prevent this buildup.

Usage Of Stale Coffee Beans

Using stale coffee beans can also result in a burnt taste. Coffee beans start to lose their freshness and flavor within a few weeks of roasting.

Bad Water

The type of water used in the Keurig machine can also affect the taste of the coffee. Using hard water or water with a high mineral content can result in a bitter or burnt flavor.

Brewing Time

Brewing coffee for too long or at too high of a temperature can also result in a burnt taste. Keurig machines are designed to brew coffee quickly and efficiently, so it’s important to follow the recommended brewing time and temperature for optimal taste.

Beans Roasted Too Long

Roasting coffee for too long can cause the beans to develop a bitter and burnt taste. This is because the heat has been applied for too long, causing the natural oils in the beans to break down and release a burnt flavor.

Other Common Factors

Other factors, such as a clogged or dirty needle, worn-out heating element, or incorrect grind size, can also contribute to a burnt taste in coffee from a Keurig machine.

How to Fix Burnt Taste Coffee on Keurig

I understand the frustration of burnt-tasting coffee and the desire to fix it. Here are some tips on how to do so:

Adjust Brewing Time

If you’re experiencing a burnt taste, it could be due to over-extraction, which happens when the water passes through the coffee grounds for too long. To fix this, you can try adjusting the brewing time on your Keurig machine. One way to do this is to select a smaller cup size, which will reduce the amount of time the water passes through the coffee grounds.

You can also try brewing with the “strong” setting, which will slow down the brewing process and result in a bolder flavor. It’s important to note that the ideal brewing time may vary depending on the type of coffee and your personal taste preferences. Therefore, it’s essential to experiment with different settings and find the one that works best for you.

Descale Keurig

Coffee bean oil buildup can contribute to a burnt taste in your Keurig coffee. Over time, the oils from the coffee beans can accumulate in the Keurig machine and on the brewing components, causing a bitter taste. To fix this, it is recommended to regularly descale the machine, which involves running a solution of water and a descaling solution (recommended by Keurig) through the machine to remove the mineral buildup. This is best done by following the instructions on the descaling solution package. This can help to prevent a burnt taste and ensure that your coffee always tastes fresh and delicious.

 Use Filtered Water

Using filtered water is crucial in fixing a burnt taste in your Keurig coffee. Keurig recommends using filtered or reverse osmosis (RO) water in its machines. If you use unfiltered tap water, the minerals in the water can accumulate inside your Keurig machine over time and cause a burnt taste to your coffee. Using filtered water can help to remove these impurities and result in a better-tasting cup of coffee.

Use Freshly Roasted Beans

Coffee loses its flavor and aroma quickly after roasting, so it’s important to use freshly roasted coffee beans for the best taste. If you’re still struggling to get a good cup of Joe from your Keurig machine, there may be an even simpler solution – switch to freshly roasted coffee beans. Stale coffee beans can taste bitter and can result in a burnt flavor when brewed.

It’s best to use freshly roasted coffee beans within two weeks of their roast date. When purchasing coffee beans, look for a roast date on the packaging, and choose the freshest beans possible. It’s also important to store the coffee beans correctly by keeping them in an airtight container in a cool, dark place, away from sunlight and heat. This will help to preserve their freshness and ensure a better-tasting cup of coffee.

Inspect the Needle

If you’re experiencing a burnt taste in your Keurig coffee, it may be time to take a closer look at the needle. The needle is what pierces the K-Cup and releases water into it, so it plays an important role in creating a flavorful cup of coffee. While inspecting your needle, check for any blockages or dirt buildup that could be causing flavor issues.

It’s also important to ensure that the needle is firmly attached to its housing and not loose or misaligned. Taking care of this problem can help restore balance in your daily cup of Joe! Regularly checking up on your Keurig’s needle can prevent problems like burnt-tasting coffee from happening in the future.

Advance Issue

A worn-out heating element can cause the machine to take longer to brew the coffee, which can also lead to over-extraction and a burnt taste. If you suspect that the heating element in your Keurig machine is worn out, it may be time to consider replacing the machine. Alternatively, you can contact Keurig customer service for support.


Troubleshooting the issue of burnt-tasting coffee from a Keurig machine can help determine the source of the problem. Common problems include using too hot water, leaving coffee grounds in the brewer for too long, or using stale or damaged coffee grounds. Cleaning and descaling the Keurig regularly is also important for optimal performance. Replacing parts such as a clogged filter or a worn-out heating element may also be necessary to ensure proper brewing temperature and extraction time. Lastly, selecting fresh and high-quality coffee beans can help produce flavorful cups of coffee instead of an unpleasant burnt taste.
