Japanese Tea Can Be Enjoyed as Cold Brew!

Did you know that almost all Japanese teas like Sencha, Gyokuro, Hojicha, or Kukicha, can be brewed using cold water? Cold brewing is an easy and refreshing way to enjoy tea that is naturally sweet, smooth, and low in bitterness. It’s perfect for beginners, kids, or anyone sensitive to caffeine.

Why Cold Brew Japanese Tea Is Different

The temperature of the water changes what compounds are extracted from the tea leaves

Hot Water (Above 60°C / 140°F)

  • Caffeine → contributes to bitterness
  • EGCG (Epigallocatechin Gallate) → gives astringency (dry, slightly harsh taste)

Hot water extracts these quickly, making your tea stronger, more bitter, and more astringent. Perfect if you enjoy bold traditional green tea.

Cold Water (Cold Brew)

  • Less caffeine and EGCG → less bitterness
  • More amino acids (like L-theanine) → natural sweetness and umami
  • EGC (milder catechin) → gentle, smooth taste

The result is a tea that is mellow, refreshing, and easy to drink with almost the same sweetness and umami as hot-brewed tea but much less harshness.

Health Benefits of Cold Brew Tea

Cold brew Japanese tea isn’t just tasty. It’s also good for your body.

  • EGC supports respiratory and mucosal immunity, helping your immune system.
  • L-theanine promotes relaxation, reduces stress, and may improve sleep quality.
  • Low caffeine makes it ideal for children or anyone avoiding stimulants.

By extracting the “good stuff” without too much caffeine or bitterness, cold brew tea gives you a balanced, healthy drink.

How to Make Cold Brew Japanese Tea

  1. Add tea leaves – about 10g per 1 liter of water
  2. Pour cold water – fresh, filtered water works best
  3. Refrigerate 2–6 hours – adjust steeping time for stronger or lighter flavor
  4. Strain and serve – tea leaves can often be used for a second brew

Tips:

  • Drink the same day for freshness and hygiene
  • Fine leaves may cause slight cloudiness but this is normal
