If your water has a sugary flavor, it is likely due to various causes. Here are some of the non-medical reasons why do water taste sweet: 

Last Consumed Meal

Consuming something with a robust flavor can alter the taste of water. It mainly happens if it is the most recent thing eaten.

If you consume something sugary before drinking, you could taste a hint of the sweetness from the delightful snack in your water.

Foods that are acidic, such as lemons or any item with citric acid, can give your water a sweet taste.

Water Source

For instance, bottled mineral water is characterized by its pleasant taste due to its alkaline properties. Additionally, tap water can also have a distinct flavor.

If you have just changed your residence, you can detect a slight variation in the water supply. It could appear sweet.

In the majority of country areas, the water that is provided through the taps comes from wells. Wells are a natural origin of water, but it usually has minerals and other contaminants.

Excessive levels of calcium and iron in water can give it a sugary taste which some people find pleasant. But if you are not keen on it, setting up a water filter or reverse osmosis system is a good choice.

Other Senses Can Cause The Sweet Taste

Are you ever compelled to dial down the volume of your car stereo when trying to make sense of complex driving instructions? You might be amazed to learn that the various senses are more intertwined than you initially assumed.

It may be surprising, but a powerful odor can influence your sense of taste and cause your water to appear sweet.

The impact of your sense of smell on your taste is generally brief. Test this by cutting an onion with a distinct odor. After smelling a strong onion odor, take a sip of water, and you may observe that it tastes sweet.


It is possible that your plumbing system could cause some modification in the taste of water.

When the amount of iron or calcium in water exceeds what is usual, it tends to have a sweet flavor. Cleaning out your plumbing system regularly can help maintain a healthy taste and maintain the natural composition of your water.

When lead pipes have polluted tap water, they may have a sweet flavor. This is a severe problem and can be hazardous to one’s well-being. You can buy a lead checker to determine this, but if you think it might be the issue, immediately get in touch with your regional water corporation.

Mineral Imbalance Or Impurities

Depending on your locality, your tap’s drinking water may contain minerals such as iron, calcium, potassium, and others.

Certain minerals & metals are available in high amounts in tap water, and people with a sharp sense of taste may be able to detect a variety of flavors in the water they consume.

Water is composed of oxygen and hydrogen, yet some aspects of the earth can dissolve and mix with water. These mineral particles or contaminants, such as iron and manganese, can modify the flavor of the water, making it taste salty or sweet. 

The tannins in tea and coffee can darken the hue of these beverages and cause discoloration of kitchen appliances and garments.

pH Imbalance

An alteration in the acidity level of water can also have an impact on its taste, as well as other aspects.

Generally, drinking water has a neutral pH. However, if any pollutants, minerals, or salts enter the water, it can lead to an elevated pH level.

To prevent this, you should consider putting a water filtration system in your home’s plumbing, such as reverse osmosis.

You were secretly hoping for a scientific explanation for why water tastes sweet. I’ve experienced this too. Here are some medical reasons why water tastes sweet: 

Nutrient Deficiencies

Nutrient deficiencies can cause sweet water. Vitamins B-12, zinc, and D are essential for keeping your senses of taste and smell in good condition. If you believe you may lack nutrients, speak to your physician about adding a multivitamin to your routine.


If you recently had something sugary, that might be why your water tastes sweet. However, this could also be a symptom of diabetes caused by a hormonal imbalance that makes it difficult for your body to control its sugar levels. This produces a sugary flavor in the mouth that you could believe is arising from your water.

Bacterial Growth In The Mouth

Have you ever encountered the phenomenon of “morning breath”? When people wake up, their mouths contain a large number of bacteria.

Occasionally, this microorganism can alter the flavor of food and drinks. It tastes sugary when you take the first sip of water, even if you’re just rinsing your mouth.

A straightforward swish with water should banish the sugary taste, but if it persists, it may be a great idea to brush your teeth or use a mouthwash that contains alcohol.

Keeping your mouth clean and healthy will help you prevent this issue.


A health issue in the ears, nose, and throat region may be the cause of why you have experienced the sudden sensation of sweetness in water.

Bacterial and viral infections that block your respiratory system can prevent your brain from sending signals to your taste buds and lead to unusual flavors and aromas or even a complete loss of your sense of taste and smell. Even small-scale diseases can raise the glucose level in saliva, which produces a sugary flavor.

You can be positive that once the other areas of your body have improved from the infection, your sense of taste should also be back to normal.

Sensory Dysfunction

Variations in sensory functioning can lead to various alterations of taste in the mouth. Some individuals may experience a lack of taste, while others may continually taste something sweet, and some may have intermittent taste changes.

People may experience a disruption in their senses if they have recently experienced a stroke or have an existing health issue.


The biological process of pregnancy can have a noticeable effect on a person’s physiology, including giving a sugary flavor to plain water.

During pregnancy, the body undergoes hormonal alterations which affect the digestive system, often resulting in cravings and peculiar flavor preferences, including an inclination for sweet water.

Medications & Medical Treatments

It is essential to understand that any medication you consume can cause some reaction in your body, and some of those reactions can be more severe than others.

Specific medical interventions such as chemotherapy can negatively affect various bodily processes. 

People undergoing chemotherapy often experience changes in their sense of taste, and the reactions vary from person to person. If you’re on chemo and find that water tastes sweet, it could be related to the treatment. However, some medicines can cause the drinking water to make you nauseous.

If you have doubts or worries regarding any of your prescriptions, bring it up with your physician.

Why Do Water Taste Sweet: When You’re Thirsty

If you have been consuming foods that dry your mouth because of their acidic or spicy nature, and your tongue is savoring these flavors, then a single swallow of water will taste unbelievably sweet.

H2O reactivates the taste buds that detect sweetness by canceling out the spicy taste, leading to a sweet sensation.

When you are incredibly thirsty, consuming water can be both a physical and emotional relief. After experiencing a lack of hydration, a tiny sip of uncontaminated tap water can activate the secretion of endorphins, increasing the delight of quenching one’s thirst.

This is why do water taste sweet when you’re thirsty.

You can set up an aeration filter in your water system to eliminate iron, hydrogen sulfide, and manganese, leaving you with safe and clean drinking water. This is an excellent approach to purifying your water without using synthetic substances. This is the ideal solution if you are drawing water from a well.
  • Alteration – An alteration in the water’s pH level might be why it has a sweet taste. To fix this, add a filter in the plumbing system of the entire house that can balance out the pH. Applying this technique will lessen the corrosion rate in plumbing, enhance the flavor of the liquid, and sustain the pH balance in the water.
  • Reverse osmosis system – An alternative approach to purifying the water and eliminating any undesirable tastes is to use a reverse osmosis system, which can eradicate contaminants. The World Health Organization (WHO) states that regularly drinking filtered water can be detrimental to one’s health since it eliminates vital minerals and nutrients, such as calcium, magnesium, potassium, and bicarbonates, which are essential for maintaining a healthy lifestyle.
