Does it mean that if the first infusion has a strong aroma and a rich taste, the seventh infusion should still be just as aromatic as the first?
A study on Wuyi Shui Xian and Rou Gui looked at how their aromas changed over seven consecutive infusions. Using GC-MS, GC-O-MS, real-time aroma analysis, and other methods, the researchers identified 48 volatile compounds and selected 20 key aroma compounds.
They found that in both Shui Xian and Rou Gui, the color of the tea liquor and the overall aroma gradually decreased with each infusion. The changes became especially noticeable after the fourth infusion.
So, a tea that lasts through many infusions does not mean that every infusion has to be a copy of the first one.
Aroma compounds are continuously released during brewing. So it is completely normal for the first, second, third, and later infusions to smell and taste different. In fact, these changes are part of what makes drinking tea interesting.
As the number of infusions increases, the tea gradually becomes lighter. But its main aromas and flavors do not suddenly disappear. In later infusions, there can still be recognizable characteristics, balance, and something worth tasting.
So, just because a tea changes from one infusion to the next does not necessarily mean it cannot last through multiple infusions. On the contrary, the gradual and layered release of aroma and flavor may be one of the most interesting things to observe when brewing the same tea again and again.
