The first step to getting your great-tasting Keurig coffee back is to keep reading this guide until the end.

5 Reasons Why Your Keurig Coffee Tastes Burnt

I have come up with all possible reasons that can cause your Keurig coffee to taste burnt and bitter. With each problem, you will find the best possible solution to fix it.

1. Your Keurig Coffee Maker is Dirty

One of the reasons your coffee tastes burnt is the poor cleanliness of your brewer. The coffee residue and oil buildup in your Keurig coffee maker affect the coffee quality.

When oil particles and residue from the previous brews are left in the coffee maker for a long time, it starts mixing into your coffee. As a result, your coffee will have an unpleasant and burnt taste.

Solution: Descale Your Keurig

Descaling removes the impurities and buildup from the internal parts of your coffee maker.

It is a process that scrapes off the buildup and calcium deposits that dries up in the brewer.

To descale your brewer, follow these steps:

  1. Turn off the brewer and unplug it.
  2. Empty the descaling solution into the water reservoir and fill it with water.
  3. Turn on the coffee maker.
  4. Place a mug on the drip tray.
  5. Press the 8 oz and 12 oz buttons simultaneously. Press the brew button to activate the descaling mode when the lights start flashing.
  6. Repeat the brew cycles till the brewer show the “add more water” message.
  7. When the brewer runs out of water, refill the water tank.
  8. Run several cleansing cycles to eliminate leftover descaling solution and coffee residue.
  9. Let the brewer sit for 30 minutes.
  10. Your Keurig is ready to brew!

2. The Water Quality Ain’t Good

The type of water you use for your coffee influences its taste and quality. Using hard water in your Keurig has a high chance of containing tons of minerals and chemicals.

Your coffee may taste funny if your local water contains high magnesium, calcium, and iron levels.

Solution: Use Filtered or Bottled Water

Consider using filtered or bottled water to improve the taste of your Keurig coffee. You can also use tap water if you are sure it doesn’t contain a high mineral content.

It is also advisable to use Keurig water filters for better-tasting coffee. The water filter purifies the water, emitting minerals and bacteria. In the end, your Keurig will produce delicious-tasting coffee.

3. The K-cups Have Poor quality.

You need to consider K-cups’ quality as they can significantly impact your coffee’s taste. Low-quality K-cups contain cheaper coffee beans that are also less in quantity.

Cheaper K-cups usually contain only 11 grams (0.40 ounces) of coffee grounds, while more expensive K-cups contain 13 grams (0.46 ounces).

Many cheap K-cups contain plastic that emits BPA when the brewer passes hot water through them. As BPA is unhealthy, your coffee may have chemicals and an unpleasant taste.

Solution: Use the Right K-cups

You can improve your Keurig coffee by choosing the right K-cup. If you put all your effort into making a fantastic cup of coffee but use poor-quality K-cups, your efforts will be wasted.

Rather than buying cheap coffee to save money, consider upgrading to better brands of K-cups.

K-cups from high-end manufacturers like Green Mountain, Starbucks, and Dunkin Donuts will cost you more, but the coffee will be a hundred times better than cheaper K-cup options.

4. You are Using Over Roasted Coffee Beans

Dark roast K-cups make a robust coffee that may not suit your taste profile. Only some people enjoy the intense and bitter coffee flavor, so the coffee may seem burnt.

On the other hand, if you use reusable K-cups, you are probably over-roasting the coffee beans. Also, If bitterness is not something you like, you shouldn’t use robusta beans.

Solution: Use Light to Medium Roasted Coffee Grounds

To enjoy a strong coffee that doesn’t taste bitter or burnt, you must switch to light to medium roast K-cups containing Arabica beans. Keurig has many flavors in its light to medium roast K-cups.

For reusable K-cups, make sure you use 100% Arabica beans that are medium-roasted. It will give you a smooth, milder, and more flavorful Keurig coffee.

5. You are Using Stale Coffee Grounds

If you use reusable K-cups, you probably have a bag of coffee beans sitting in your kitchen cabinet. The coffee grounds tend to go stale faster if you don’t store them properly.

Using stale or expired coffee beans can give your coffee an unpleasant and burnt taste. Once the coffee grounds pass the expiry date, the flavor and aroma evaporate, making them bland and burnt Keurig coffee.

Solution: Use Fresh Coffee Beans

Store the coffee beans properly to make your coffee taste the best every time. Put them in an airtight container to prevent them from coming in contact with heat and moisture.

Also, make sure you use the coffee beans before they get expire. Always read the expiry date mentioned on the coffee bean packaging. If you have stale coffee beans, time to get rid of them because there is no way to bring them back to life.

Ways to Make Your Keurig Coffee Taste Good

If you are unhappy with your Keurig coffee, there are several ways to improve it. Follow these tips to bring out the best taste of your coffee.

1. Descale your Keurig Coffee Maker

Keeping your Keurig coffee maker clean and tidy will prevent any unpleasant taste and bacteria from getting into your coffee. It is highly advisable to descale your coffee machine every 3 to 6 months, so it makes delicious coffee consistently.


Also, clean all the removable parts with soapy water and a non-abrasive cloth to keep any residual substances out of contact with your coffee. You must also change the water filter every 2 to 3 months, so the water gets purifiers before brewing coffee.

A well-maintained Keurig brewer goes a long way makes high-quality coffee and preventing any technical mishaps.

2. Maintain your Coffee’s Temperature

When your brewer prepares a delicious cup of coffee, it will likely lose its charm if you let it cool down. It’s ideal for indulging in your freshly brewed coffee while it is hot and delicious.

You can preheat the coffee machine to ensure you get a good hot coffee. All you got to do is fill the water tank and run a brew cycle without inserting a K-cup. This way, your coffee will be hotter.

Or you can preheat the recipe mug by adding water and warming it in the microwave for a few seconds. Then discard the water and use the cup for your Keurig coffee.

3. Use The Strong Button

If your Keurig has a strong button, use it to enjoy a more robust and delicious cup of coffee. And if you plan to upgrade your coffee brewer, get one with the “strong button” option like the Keurig K-express.

The water flows more slowly through the K-cup when you press the strong button. This results in more coffee extraction, producing a more robust cup of coffee.

Adding 30 seconds to the brew time extracts the optimal flavors of the coffee containing balanced bitter, sweet, and acid compounds.

Why Does My Keurig Coffee Taste Bad Even After Cleaning?

So, you brew a cup of coffee after cleaning the coffee maker thoroughly, but it consists of a poor aftertaste? It might be due to some chemical or residue lingering in the coffee maker.

After cleaning the coffee machine, the descaling solution or vinegar can leave an unpleasant taste that mixes up in your coffee.

Here are a few things you can try if your Keurig coffee tastes bad:

Run Several Cleaning Cycles

Remove the K-cup from the coffee machine and fill the reservoir with water. Next is running several brew cycles until the coffee maker runs out of water.

Run brew cycles till the coffee maker runs out of water. Refill the water tank with fresh water to brew coffee.
