Many tea lovers are alarmed by the film that sometimes forms on the drink.
Some people believe that it is not possible to drink a drink with such a whitish coating.
We hasten to reassure those who consider tea film dangerous: in fact, it is harmless.
Contrary to popular belief, it is not the detergent that is causing the problem, traces of which supposedly remain on the cup after washing the dishes.
The assertion that the film appears due to the “melting” of wax on the surface of the tea leaves is also erroneous.
The real reason for the whitish coating is that compounds in tea react with calcium carbonate, which may be present in tap water.
The film that appears on the drink is absolutely safe for health.
If you don't like the plaque from an aesthetic point of view, try making tea using bottled water instead of tap water.
The minimal content of impurities in such a liquid will significantly reduce the risk of film formation.
You shouldn't use distilled water: along with the film, the tea will lose its bright taste.
