Why Is My Coffee Cloudy? 5 Common Reasons

Even though brewing coffee seems like a fairly easy task to do with very few things that can go wrong, they can indeed go wrong and produce coffee that tastes bitter, bad, burnt, runny, muddy, and cloudy.

The common reasons behind the problem of making cloudy coffee are discussed thoroughly in the chapters below. One of these reasons can be behind your coffee coming out cloudy or multiple reasons can be causing the issue.

1. Brewing Method

The brewing method is important when it comes to ensuring that your coffee comes out tasting good and not muddy, cloudy, or bitter. One of the most common issues that cause cloudiness in coffee is the coffee machine brewing the coffee at an inaccurate temperature.

The best coffee is brewed at temperatures between 90 C to 96 C or 195 F to 205 F. Try to maintain this temperature while brewing coffee to make sure that the coffee you are brewing comes out hot and fresh.

Another common reason for cloudy coffee is brewing the coffee for less than two minutes. You should always brew coffee for longer than two and a half minutes to ensure that the coffee is brewed properly.

Pressing coffee too vigorously can also cause the coffee to get murky or cloudy. Make sure to brew coffee slowly and finely with the French press and always make even numbered presses.

2. Coffee Beans

Coffee beans can also be the reason behind the coffee coming out cloudy or murky. Old or rancid coffee beans leave residue in the coffee and make it cloudy and murky. Stale coffee beans produce cloudy coffee because rancid oils come out from the coffee beans as they oxidize when they come into contact with the air.

This can also happen if you leave your coffee out at room temperature for more than four hours. Microwaving cold coffee will not bring back the taste of the hot coffee and it is better to throw it in the sink and brew a fresh batch of coffee.

Store the coffee beans in an airtight container to make sure that the beans do not get oxidized and get coated with unwanted rancid oils. Brewing old or rancid coffee beans will always provide you with murky or cloudy coffee.

3. Water Quality

The water quality can hugely affect the nature, taste, and texture of the coffee you brew in it. Coffee brewing water should ideally have a pH between 6.5 and 7.5 which is in the best range to balance the acidity that the coffee will add to the water. Tap water often contains chlorine and other minerals that are not harmful to humans but can cause the coffee to turn out bad.

You should use purified water from filters or plastic bottles. You can use tap water if the supply is clean but make sure that the water does not contain excessive chlorine, fluoride, and other minerals.  

4. Faulty Coffee Maker

Cloudy or murky coffee can also be a result of using dirty or faulty coffee makers. Dirty coffee machines contain high amounts of residue from grounds, old coffee, and minerals from the water. These contaminants enter into the coffee when you use an old or dirty coffee maker to brew coffee.

Cleaning your coffee makers regularly will solve this issue. Rinse the coffee maker with hot water after you are finished brewing coffee and use soap water to clean the coffee maker at least once a week. This will prevent the coffee from getting too cloudy or murky when you use that machine to brew coffee.

5. Coffee Filters

Coffee filters can also cause the coffee to get cloudy. This problem is more common for bleached coffee filters because the chemicals in the bleached filter enter the coffee and then turn the coffee murky or cloudy.

Use unbleached brown papers for filtering brewed coffee as it does not have these chemicals that can make the coffee murky or cloudy. Brown filter papers filter out the oil and residue from coffee and provide a clear and bright brew with a crisp taste. You can also use cloth filters to filter out unwanted oils and residue.

What Happens When the Coffee Is Cloudy?

When coffee is cloudy, it contains oil and other unwanted particles in it. This decreases the taste and fine aroma that coffee naturally gives. The cloudiness also makes the coffee less appetizing as the color looks awful. The coffee also gets a different texture from regular coffee which is also not appealing. Overall, the coffee gets ruined when it gets too cloudy.

Is Cloudy Coffee Good or Bad?

Cloudy coffee is a bad sign and it means that something has gone horribly wrong while brewing the coffee. Cloudy coffee might not be harmful for the body if you drink it but the experience is unpleasant as the coffee tastes bitter, burnt, and unappetizing because the taste and aroma get degraded.

Is Cloudy Coffee Safe to Drink?

Cloudy coffee is usually safe to drink but it should be avoided because there is no guarantee about what substance is causing the issue.

How to Prevent Coffee From Being Cloudy?

Cloudy coffee leaves a bad taste in the mouth as it is bitter, rancid, and awful. But there are some methods by which you can ensure that the coffee comes out clean every time you brew coffee. These are discussed below.

1. Choosing the Right Coffee Beans

Coffee bean selection is of utmost importance to make sure that the coffee you brew does not come out cloudy. Rancid and old coffee beans will always produce bad-tasting cloudy coffee which is why they should be avoided at all costs.

Check and double-check before you grind your coffee beans to ensure that they are new, fresh, and do not have any bad smell to them. Quality coffee beans provide a quality brew.

2. Brewing the Coffee Properly

The brewing method affects the taste and texture of the coffee so it is necessary to be careful while you are brewing your coffee. Make sure that you brew coffee for more than two and a half minutes at the minimum to ensure a nice brew.

Gently use the French press if you are using that to brew coffee and always give even numbered presses. Make sure that the temperature is between 90 C to 96 C or 195 F to 205 F.

3. Using Quality Water

Do not use tap water if it contains too much chlorine, fluoride, and other minerals. Use filtered and purified water with low amounts of minerals present in it for brewing coffee. 

Frequently Asked Questions

1. Does Adding Milk Make My Coffee Cloudy?

No, milk does not create the cloudiness in the coffee, the oil and dust residue left from the coffee do.

2. Does Cold Brew Coffee Get Cloudy?

Yes, cold brew coffee can get cloudy because it uses finer grind coffee. But the cold brew usually gets cloudy because of impatience. You need to brew the coffee for at least 10 hours and up to 20 hours if you want a good cold brew. Otherwise, your cold brew will make cloudy coffee.

3. Can Hard Water Make My Coffee Cloudy?

Yes, hard water can make your coffee cloudy because the minerals present in the hard water react with the coffee and create cloudiness.

4. Why Does My Coffee Look Muddy?

Coffee usually looks muddy because the grind was too fine and everything did not get filtered properly causing a lot of suspended solids in the coffee brew. These suspended solids create the muddy appearance of the coffee.
