Enjoy making your own cold brewed green tea at home.  

Put water and the leaves for 6 to 12 hours in refrigerator then shake gently for the color as you wish to see.

Also after enjoying them as cold brew, you can add hot water to the same tea leaves you used so that you will experience different flavor.

Cold brew means the water used to brew has lower temperature, which results in less extraction, and smoother flavors.  Output will be sweeter and have a heavier mouthfeel than hot brew. It also can be stored in the refrigerator after brewing for about 1 week. Once you have the desired extraction, take brewed tea out of contact with the water.
