Reboiling water spoils tea: chemists explain the reason.

According to ТСН: Chemists explain: when water is reboiled, it loses some oxygen, which is responsible for the freshness and smoothness of the taste.

When new water is added to a teapot, the old water mixes with the new. This leads to the taste becoming flat, heavy, and unnatural. Additionally, multiple boiling increases the risk of scale formation, as calcium and magnesium salts settle on the walls of the kettle, altering the taste of the water.

Experts note: tea brewed with such water loses its aroma, as tea leaves do not open up fully, and the drink becomes bitter.

Research shows that reboiling increases the concentration of nitrates and fluorides in the water, which can be harmful in large quantities.

Expert Recommendations

Experts advise pouring only the amount of water needed for preparation into the kettle. This simple rule will help maintain the taste and quality of the drink.

Tea masters emphasize that the taste depends not only on the type of tea leaves — water also plays a significant role. In China and Japan, water for tea is treated with great care, and reused boiled water is never used.

Tea sommeliers insist: even a novice will feel the difference immediately. Tea made with fresh water is always softer and more aromatic.

Impact on the Kettle

Reboiling also leads to wear and tear on the kettle. Scale damages heating elements and shortens the lifespan of the device. Engineers recommend regularly cleaning the kettle from scale, but the best option is to simply prevent its formation.

Some housewives believe that topping up water saves time and resources, but in reality, this often leads to extra costs for repairs or replacement of the kettle.

Thus, the habit of adding water to the kettle after boiling is one of the most harmful, as it spoils both the taste and the quality of the drink.

In general, to preserve the taste and aroma of tea, it is worth adhering to simple preparation rules. Using fresh water not only improves the quality of the drink but also extends the lifespan of the equipment. Kettle owners can save on repairs by following these recommendations and paying attention to the amount of water in the kettle.
