Why does tea make my mouth dry?

In this brief guide, we will answer the question “Why does tea make my mouth dry?” its effects on the mouth, and remedies to solve this problem.

Why does tea make my mouth dry?

Tea makes the mouth dry since it has increased levels of tannins, this also has oil content with less quality that causes sensation and it is known as astringency which makes the skin and mouth dry. 

How do Tannins in tea make the mouth dry?

Tannic acid and other tannins present in tea, interact with enzymes and proteins in the body, as well as in the mouth. The bitter feeling is produced by an interaction between tannic acid and proteins in the saliva.

In contrast, the tannins in your tea stimulate the epithelium in the mouth to constrict. This amplifies the impact, and these responses combine to give you the taste you’ve felt.

Why are the tannins present in leaves?

Tannic acid allows the plantation to defend itself from microbial pathogens that would otherwise hinder or indeed kill the tea plant’s capacity to thrive. Tannins get it by adhering to metabolic enzymes, preventing pathogens from growing. Furthermore, this trait inhibits bigger animals from consuming the tea plant’s foliage or stems.

What affects the quantity of tannin in tea?

There will be tannins in the tea leaves, regardless of the type of tea you purchase (and stems). During manufacturing, this isn’t modified significantly.

Tannins are not removed from tea leaves by oxidative stress or post-fermentation. Drying the tea leaves properly helps to reduce tannins. Tannic acid, on the other hand, dissociates at temperatures exceeding 400 degrees Fahrenheit (200 degrees Celsius). As a result, toasting is a potential option for destroying tannins.

Aside from this method of processing, there are several things you may do while brewing your tea to avoid a dry mouthfeel.

Variation in temperature of the water 

Tannins are particularly soluble in water, and tannic acid will be no exception. This reduces the impact of water temperature on tannic acid absorption from tea leaves.

Many other chemicals in tea are more dissolvable in boiling water than in ice water, but tannin mobility is too intense for this to be a realistic solution. However, you can make use of tannic acid’s strong water solubility. With a semi-quick rinse in cold water, you may remove most of the tannic acid from the tea leaves.

Affect on steeping time and stirring

During prolonged soaking times, the quantity of tannic acid removed from the tea leaves improves. The recovery rate can be increased by stirring or moving the boiling pot.

This is due to the fact that tannins in the center of the tea leaves require years to finish the liquid than those at the edge. As a result, you won’t be ready to fully eliminate the tannins with a washing. Inside the leaves, a small quantity of tannic acid will persist, but it will be negligible.

Prefer the right quantity of leaves 

The content of tannins in the produced tea seems to be more essential than the quantity of tannic acid you consume. During the research, You would have some unpleasant experiences with a strong tannic acidic medium.

The quantity of tea you use might be too high if you have a tea that causes a dry sensation. With reduced leaf-to-water ratios, tannins become less prominent. When you increase the level of tea in a sample of water, the tannin absorption significantly increases. I’d suggest making relatively similar tea with fewer tea leaves and hence more water.

Identify the leaf grade and area 

The leaf grading is something else to think about. Dust, fannings, and shattered leaf, including the whole leaves are the most prevalent grades.

Tannic acid is found throughout the tea leaves and is much easier to separate from tea powder or fannings than it does from complete leaf tea. On a more practical level, the larger surface area and narrow size distribution lead to rapid extraction of all tannins. 

What is the recipe for tea which will reduce mouth dryness?

  • You need to adjust the ratio between water and leaf such that the concentration of tannins will be leveled properly.
  • You must use tea leaves of premium quality as tannins are taken out easily from them rather than broken tea leaves as they aren’t easy to be extracted. Also good quality of tea leaves reduces the dry effect.
  • You must wash the leaves well with cold water such that it helps to remove excessive tannin content in an easier way.
