What Is Unsweetened Tea?
Unsweetened tea has its origins in the Camellia sinensis plant, which is the source of all true teas, including black, green, oolong, and white tea. Herbal teas, on the other hand, are made from a variety of other plants and are not derived from the Camellia sinensis plant. Teas have been consumed for thousands of years, with many regions cultivating their own varieties and processing methods.
How It Is Made
To create unsweetened tea, the leaves of the Camellia sinensis plant are harvested, withered, and then processed depending on the type of tea desired. For example, green tea leaves are typically steamed or pan-fired to prevent oxidation, while black tea leaves are allowed to fully oxidize, giving them their darker color and stronger flavor.
The processed leaves are then brewed in hot water to extract the flavor and beneficial compounds, such as antioxidants and flavonoids, resulting in unsweetened tea.
There are a variety of market forms for unsweetened tea, ranging from loose-leaf to pre-packaged bags or sachets, as well as ready-to-drink bottled varieties. The teas can be found in several forms, including:
- Loose-leaf. Tea leaves are sold in bulk and you can measure out the desired amount for brewing.
- Tea bags. Pre-measured tea leaves are contained in a paper or fabric bag, ready for brewing.
- Sachets. Similar to tea bags, but often contain higher-quality tea leaves and provide more room for the leaves to expand while brewing.
- Ready-to-drink. Bottled unsweetened tea can be found in grocery stores and convenience stores, typically in the refrigerated beverage section.
Ways of Preparation
There are several ways to prepare and cook unsweetened tea, depending on your preference:
- Traditional hot brewing. Add tea leaves (either loose-leaf or in a bag/sachet) to a teapot or teacup and pour hot water over them. Let the tea steep for the recommended time based on the tea type—usually between 2 to 5 minutes for green and white teas, and 3 to 5 minutes for black and oolong teas.
- Cold brewing. Place tea leaves or bags in a pitcher or jar and fill it with cold water. Let the tea steep in the refrigerator for several hours or overnight. The resulting tea will be smoother, less bitter, and lower in caffeine since the cold water extracts fewer tannins from the leaves.
- Sun tea. Similar to cold brewing, but instead of placing the container in the refrigerator, it is left outside in direct sunlight for a few hours. This method can also result in a smoother, less bitter tea.
Remember, the key difference between unsweetened tea and sweetened tea is the addition of sugar or other sweeteners. To keep your tea unsweetened, simply avoid adding these sweeteners during or after the brewing process. Enjoy the natural flavors and potential health benefits of unsweetened tea as a part of your daily routine.
In unsweetened tea, you’ll usually find a few common ingredients that make up the base of this beverage. It’s essential to be aware of these ingredients as you explore whether unsweetened tea is a good choice for your daily routine.

Health Benefits of Unsweetened Tea
Being a water-based beverage, tea is a great way to keep your body hydrated. Adequate hydration is essential for maintaining bodily functions such as digestion, nutrient absorption, and regulation of body temperature.
Rich in antioxidants
Unsweetened tea, particularly green tea, is rich in powerful antioxidants such as polyphenols, catechins, and tannins. These substances help protect your cells from damage by neutralizing harmful free radicals, thereby reducing the risk of chronic diseases and slowing down the aging process.
Regular consumption of unsweetened tea, especially green and black teas, has been associated with a lower risk of heart disease and stroke. The antioxidants in tea can help improve blood vessel function, reduce inflammation, and lower both blood pressure and cholesterol.
Tannins in tea can have a soothing effect on the digestive system. They help to combat intestinal and gastric illnesses and can contribute to proper digestion.
Certain types of unsweetened tea, like green tea, have thermogenic properties that can help boost your metabolism, increase fat oxidation, and hence, assist in weight management.
Blood sugar control
Unsweetened tea, being a no-sugar beverage, can help manage blood sugar levels and reduce the risk of type 2 diabetes. Some studies also suggest that the polyphenols in tea may improve insulin sensitivity.
Tea contains a combination of caffeine and L-theanine, an amino acid, which work together to improve brain function. They can help increase alertness and improve focus, making tea a popular choice for those needing a mental boost.

According to a study published on NCBI, drinking black tea regularly may help reduce the chances of developing cardiovascular disorders. Unsweetened tea is also a great option for individuals with diabetes, as it doesn’t contain added sugars that could cause spikes in blood-glucose levels.
A comprehensive umbrella review of existing research indicates that consuming two cups of unsweetened tea daily could reduce the risk and progression of cardiovascular disease (CVD). Regular tea intake appears to improve both established and emerging CVD risk markers, such as blood pressure and cholesterol levels, likely due to its high flavonoid content.
While high-dose supplemental intake can cause side effects like hepatotoxicity and gastrointestinal disturbances, moderate consumption of tea as a beverage generally seems more beneficial than harmful.
Based on data from the 2011-2016 National Health and Nutrition Examination Survey, a study found that tea drinkers, predominantly older adults and higher-income individuals, tend to have healthier diets and better cardiovascular biomarkers. Regular tea consumption was associated with diets high in protein, fiber, and certain minerals, and low in added sugars and alcohol.
These consumers also exhibited higher levels of “good cholesterol” and lower body mass indexes. The study underscores a potential link between tea drinking and healthier lifestyle choices, especially among those in higher socioeconomic brackets.
