You belong to fans of the tea drink and you have already noticed at least several times that Foam, turbidity or sheepskin appeared on its surface? In this article we will tell more about why such phenomena take place. Although at first glance they may look disturbing, In fact, they have their natural causes.
Foam on tea – where does it come from? Well, it turns out that This is one of the most common phenomena that can be observed when brewing this drink. Many people often notice it after pouring boiling water on the tea list, especially when brewing black and green. This phenomenon does not appear every time, but when it occurs, it is worth knowing why this happens.
Foam on tea is formed as a result of the content of natural organic compoundssuch as polyphenols that are responsible for the color of the infusion and its health properties. When brewing, these substances react with water, forming air bubbles on the surface of the drink. It is worth emphasizing that Its presence is not a sign of spoilage of tea – On the contrary. It is its lack that indicates the low quality of the product.
The only type of foam that should raise your doubts is one with a yellowish or greenish color and a strange taste. In this case, it is better to give up enjoying your favorite infusion.
Another question that often falls from the mouths of the enthusiasts of a black infusion is – Why is tea cloudy? This phenomenon is also not a reason for concern. It happens that after brewing, the tea drink acquires slight turbidity and there are several reasons for it.
Firstly It is related to the type of drink. With a high content of small leaves, for example, ground and in handbags, it can easily produce a cloudy infusion. What’s more, when brewing, small tea particles can be released into the water.
The second factor is water temperature. For hot fluid, it can cause too many ingredients to release. A similar effect may give brewing too long. What else is worth remembering? For example, the fact that the catechins contained in the tea are oxidized, which means that it can gain a yellow shade and cloudy, resembling tea combined with yellow milk.
Tea sheepskin – what does this phenomenon mean? It may appear when it stands in a cup or jug for some time. It often resembles a whitish settlement, which is formed in a characteristic sheepskin coat. It is the result of the presence of natural essential oilswhich are released when brewing tea, especially in the case of black and green.
The sheepskin can also arise as a result of high water hardnesswhich in combination with minerals is set on the surface of the infusion. Most often it appears on water with high concentration of calcium and magnesium. What is worth knowing about him? First of all, that It is completely safe to eat and does not affect the quality of tea.
Do you not want a sheepskin coat to appear on your drink? In that case, steer tea a bit shorter and use soft water for this. The principle is very simple – the harder the water, the greater the probability of its formation.
