Tea Cold Brew Guide

Water temperature plays a large role in the taste emitted from tea leaves.  For example, boiling water may scald tea leaves, leaving an acidic aftertaste.  To enjoy the undertones of tea leaves, reduce the water temperature by placing tea leaf and water infusion in the refrigerator for 6-8 hours.  Some tightly rolled oolongs may rest at room temperature in water for  about 5 minutes to allow leaves to expand and color to form slightly before placing in the refrigerator.

Recommended to use mineral spring or filtered water. 


  • Glass Jar with Lid
  • Food Scale
  • Tea Leaves
  • Water (Mineral Spring or Filtered)
  • Stirrer
  • Filter
  • Glass Pitcher with Lid


Cold Brew Ratio: Tea Leaves to Water 

  • 1 g of tea leaves to 100 mL of water.
  • Which is approximately 2.5 g of tea leaves for every 1 cup of water.


Step 1:  Prepare a wide mouth clean glass jar or other glass vessel with sealable lid.

Step 2:  Measure out the amount of water you plan to use.  Based on the water amount, use the above Cold Brew Ratio to determine the weight of tea to be used.

Step 3:  Measure the tea leaves with a food scale.

Step 4: Pour room temperature water into the glass jar, add tea leaves on top.  Stir water into a tornado that whisks the tea leaves into the water.

Step 5: Cover the jar with a well sealing lid. 

Note:  Some tightly rolled oolong teas may sit at room temperature for about 5-10 minutes (more or less depending on the warmth of the room) and expect the water color begin to change and leaves to start expanding.  

Step 6: Move the tea water infusion jar into the refrigerator for 6-8 hours.

Step 7:  Remove the tea water infusion jar from the refrigerator.  Use the filter to strain out the tea leaves as you pour into a glass pitcher with lid. 

Step 8: Enjoy your cold brewed tea for up to 48 hours.
