If you like to start the morning with a cup of black tea, the details of the new study how to make it feel better. Apparently, the ‘pure’ water system found in many houses reduces the taste of your tea, making it more bitter than if brewed using ‘impure’ water that forms a film on drinks.
If you have ever made a cup of hot tea and see the thin film shape above the cold surface, it’s a good beverage, according to the new research from Et Zurich. The candle film was formed because of a combination of milk, sugar, acidity, how concentrated in tea, the temperature was brewed, and how hard the water was.
The last part is probably the key to improving someone’s brewing skills, depending on where one life. Although manyplaces have ‘hard’ water naturally giving a clearer sense, the house often has a mounted water purifier that produces soft water. While it helps prevent mineral buildup in water pipes, it also leads to tea that tasts bitterly.
In describing how they studied the film, co-author of Caroline Research Giacomin said:
In interfacial reign, experiments carried out involving metal devices placed on the surface of the tea. The device rotation is carefully controlled, and the resistance to the rotation used by the film is what allows us to determine its strength.
The researchers found that films in tea were mostly the results of calcium carbonate reacting with tea compounds. Adding something sour to tea when using a dry mixture, the researchers noted, increasing the taste while reducing how visible the film was. Acid compounds can, for example, oranges.
