For those who mostly drink bottled tea, this summer, We highly recommend “Super Green Tea”! Not only does it have 50% more umami, but it also revitalizes immunity with the new component “epigallocatechin.” Plus, it contains almost no caffeine, making it perfect for children and safe to drink before bed!
The secret to achieving this super green tea lies in the method of brewing it with “ice water for five minutes.” This technique is actually used in the production areas. By using low temperatures for a short time, the bitterness and astringency (catechins) that can interfere with the umami are minimized, allowing even regular, affordable tea to have the exquisite sweetness and umami of gyokuro (high-quality green tea).

Ice Water Brewed Green Tea
- Ingredients: Use 10g of sencha (green tea) and 100ml of ice water.
- Brewing Method:
- Place the sencha in a teapot and add the ice water.
- Wait for about 5 minutes (this may vary slightly depending on the brand).
- Use a strainer to pour the tea into a cup.
Notes:
- Avoid using “deep-steamed tea” as it can become bitter even when brewed with ice water.
- Any type of sencha will enhance its umami when brewed this way, but high-quality sencha is recommended for a richer flavor and aroma. Be cautious of inexpensive teas that may contain deep-steamed tea or finely crushed leaves.
- After drinking, store the teapot in the refrigerator to brew more ice water tea multiple times. However, make sure to pour out all the tea after each brew to prevent spoilage (consume within one day).
- The first brew will have the strongest aroma, but you can enjoy the flavor for 4-5 brews.
- If the taste becomes weak, adding hot water will restore a flavor similar to that of traditionally brewed tea, resulting in a slightly astringent tea rich in catechins.
