@ Yonghe Nine Minor pointed out something beyond common knowledge: “Tea brewed with hot water and then cooled isn't tasty. However, you may not know that cold-brewed tea is popular in places like Korea and Japan. In Japan, cold-brewed tea is known as Mizukiri-cha (water-dripped tea).”

How can tea be cold-brewed to best display its charm?

Is cold brew tea a bit of a break from tradition?

1 Cup of cold brew tea = 10 cups of hot tea. Is this somewhat revolutionary?

Compared to tea made with hot water, the nutrients are maximally extracted, and the taste is not at all bitter, making it perfect for summer consumption. Cold brew tea not only quenches thirst and clears greasiness but also has specific benefits for lowering blood pressure and uric acid levels.

Preserving Beneficial Substances Completely

Tea contains over 700 types of nutrients. Cold brewing avoids the destruction of the tea Leaf's cellular structure by temperature, preserving the beneficial substances intact. This conclusion is supported by research data. According to a report in the Beijing Morning Post, Lin Zhi, Director of the Tea Research Institute of the Chinese Academy of Agricultural Sciences, once presented a foreign study on cold-brewed tea. Published in the Journal of Food Composition and Analysis, the study showed that overall, the polyphenols, catechins, and antioxidant activity in cold-brewed tea were better than those in tea made with hot water.

Brewing tea with room temperature water for a longer time allows the leaves to fully expand and release their beneficial substances into the tea. Room temperature water does not damage the cellular structure of the leaves, ensuring the integrity of the active ingredients, resulting in a beverage richer in polyphenols.

Outstanding Effects in Lowering Blood Pressure, Lipids, and Glucose

Polyphenols are a group of polyphenolic substances abundant in tea, proven to lower blood sugar, lipids, prevent hypertension, cerebral thrombosis, and arteriosclerosis. Theaflavins, the oxidized polymers of polyphenols, also have effects similar to polyphenols in the prevention and treatment of diabetes. Additionally, theaflavins can lower cholesterol, which is beneficial for preventing and treating cardiovascular diseases and arteriosclerosis, common complications of diabetes. Cold-brewed tea, due to its longer Steeping time, allows for the full extraction of polysaccharides, which is beneficial for patients with type 2 diabetes. After two hours of cold brewing, the maximum amount of catechins, polyphenols, theaflavins, and polysaccharides is released.

Does Not Affect Sleep

Green Tea steeped in cold water for 4 to 8 hours effectively extracts beneficial catechins while releasing only half the caffeine that might affect sleep. This method reduces caffeine release, is gentle on the stomach, and does not impact sleep. Additionally, since less Tannic acid is released, the bitterness of cold-brewed tea is less pronounced compared to hot-brewed tea.

How to Cold Brew Tea

Cold-brewed tea involves using cold water to steep tea leaves. Cold water can be tap water, mineral water, or purified water, at room temperature. Mineral water provides the best taste when used for cold brewing. A good-tasting cold-brewed tea has a natural sweetness without added sugar and a smooth flavor. Cold brewing increases the potency of the tea, but it requires higher quality tea. New tea is best for cold brewing to achieve an aromatic and flavorful taste. Lightly oxidized teas, such as green tea, lightly oxidized oolong tea, and moonlight white tea, are suitable for cold brewing. Highly oxidized teas like black tea, Tieguanyin, and Pu'er tea do not work well for cold brewing, as they become bitter and lose their aroma.

Three Steps to Healthy Cold-Brewed Tea

After preparing the tea leaves, cold water (or mineral water), and a glass container, use a ratio of approximately 50 ml of water per gram of tea leaves for the best taste, although you can adjust according to your preference. After letting it sit at room temperature for 2 to 6 hours, the tea can be poured out and consumed (or filtered and refrigerated). Green tea requires a shorter time, about 2 hours, while oolong and white tea need more time. Therefore, while respecting tradition, we should also be open to trying new things, which is our best choice.
