What qualities of coffee and tea change when water temperature is off

Tea tastes weak or bitter mainly because of leaf size, water temperature, and the size of the brewing vessel. Large leaves need more time or a light break to release flavor, while water that is still too hot masks subtle notes and can pull out astringency. Letting the cup cool to about 160°F often makes those quieter qualities easier to taste.

The same qualities of coffee apply to tea: water temperature and contact time decide how much is extracted. If sweetness fades after the first infusion, raising the water temperature slightly on later pours helps. A brewing vessel that is too small also stops leaves from expanding, so the liquor stays thin. Repeated brewing beyond the leaf's capacity mainly risks a flat, bitter cup rather than any real safety concern.

Have you ever encountered a situation like this: you take out your gaiwan, choose a tea you particularly like, brew it, and then find that the taste is not as good as you remember? Or perhaps due to a momentary lapse, the tea soup becomes bitter and astringent? In fact, there are many factors that affect the taste of tea soup, from the form of the tea leaves and the water temperature to the choice of brewing vessel, all of which directly influence the final flavor performance. This article will systematically sort out the common reasons why tea soup is too light or too bitter, and share some practical adjustment techniques to help you better release the aroma and sweetness of the tea. In addition, we will also discuss the potential risks that may arise from repeatedly brewing tea leaves too many times, so that while enjoying the fragrance of tea, you can also drink with greater peace of mind.

Have you ever had this experience: you pick up your gaiwan, select your favorite tea, brew it, and find that it does not taste as good as you remember?

Or you forgot, and now it is too bitter?

In any case, we have gathered some tips to improve the taste, so let's take a look at the following issues!

The taste is too light

The larger the tea leaves, the longer the brewing time

Next time, try breaking the larger tea leaves a bit to let the flavor come out, while also making it easier for water to enter the tea leaves.

You will end up with a more delicious coffee

Sometimes the taste of tea fades faster than we think. If you notice that your tea loses its sweetness only after the first brew, then try slightly increasing the water temperature in the subsequent infusions.

Some teas require a higher brewing temperature, and sometimes when we taste shortly after brewing, we cannot taste the subtle qualities of the tea because the water is still a bit too hot and our sense of taste cannot capture the subtleties in it.

We recommend waiting first for the tea to cool a little in the cup, preferably to around 160ºF (for a small gongfu teacup, this should not take too long). Try this technique and see whether you can catch some of the more subtle notes.

Check whether the brewing vessel you are using is too small

Give the tea leaves more room to expand

Sometimes, the tea leaves do not expand enough to release all their flavor into the water, and the brewed tea is a bit tasteless.

The tea soup is too bitter

Try slightly lowering the water temperature until your tea has enough flavor without astringency

Another good way to avoid bitterness in tea is cold brewing, which allows the sweetness to be released slowly and leaves the unpleasant bitterness behind.

Try pouring the tea from one vessel into another. This not only allows the tea to cool, but also lets it breathe, allowing the bitterness to dissipate and making your brew sweeter and more aromatic!

The bitterness we feel in tea is a direct result of tea polyphenols, that is, tannins. Although they are good things, in general, the higher the water temperature, the more pronounced they become, while the lower the water temperature, the more pronounced the amino acids become (these amino acids are the cause of sweetness in tea). Amino acids dissolve at 140°F, and tannins dissolve at 176°F.

For this reason, we usually do not brew green tea at temperatures above 176 degrees Fahrenheit, and generally keep it at this temperature to achieve a perfect balance in the taste of the tea.
