- Cold-brewing teais healthier. Makingtea with hot water will lead to release of a large amount of caffeine. Especially, drinking hot strong tea after meals will affect people’s absorption of iron. In addition, excessive caffeine will make the heart beat faster and stimulate gastric juice secretion. Cold-brewing tea can perfectly solve these problems, and the polysaccharide in cold-brewing tea is better preserved, which is suitable for diabetics to drink.

How long should it take to make the best cold-brewing tea?
This is a question that many tea lovers concerns.
On this issue, some professional researchers have done experiments of making cold-brewing tea with green tea and oolong tea. 3g, 4g, 5g and 6g of green tea were respectively weighed, poured into 300 ml of water and shaken well. Sensory evaluation was conducted after 0.5h, 1.0h, 1.5h, 2.0h and 3.0h respectively. The results showed that when the tea-water ratio is 4:300 for steeping time 1.5 hours, and when the tea-water ratio is 5:300 for steeping time 1 hour, the green tea aroma and taste are relatively better.
And in the experiment of making cold-brewing tea with Oolong tea, the results showed that when the tea-water ratio is 5:300 for steeping time 2 hours, and when the tea-water ratio is 6:300 for steeping time 1.5 hours, the Oolong tea aroma and taste are better.
As the steeping time gets longer, the more intense tea aroma is, and the more bitter and astringent the tea becomes. This is because that Longer steeping times result in higher quantities of caffeine being extracted, and the tea soup will gradually become dim and turbid. This is because that catechin undergoes oxidative polymerization under the enzymatic action and forms red and yellow pigment substances, eventually leading to the difference in color and lustre of tea.
What calls for special attention is that it is appropriate to drink off the cold-brewing tea within 3-5 hours. If not finished up, it had better be put into the refrigerator for cold storage, with the temperature set at 4℃, but the storage time should not exceed 12 hours.
Also, cold-brewing tea had better be brewed not more than two times. Otherwise, the cold-brewing tea will have great difference in appearance, aroma and taste from the first flush.
