Step 1: Get your materials: Tea, Kyusu or other brewing vessel, and Ice. Then place about 25% of the tea in the bottom of the Kyusu or other vessel
*Note--if you are going to ice brew you should not sacrifice water quality--I have a sepearate tray I use with high quality filtered water for my ice cubes:

Step 2: Add several ice cubes filling the Kyusu about 1/3 of the way and add the same amount of tea you have on the bottom of the Kyusu on top of the ice; add more ice filling up to about the half way point of the Kyusu:

Step 3: Repeat step 2 adding more tea on top of ice on top of tea twice more until the kyusu cannot contain any more ice:

*Filled to top:

Step 4: Add about 1 oz (depending on size of your Kyusu....I fill mine up to about a 6oz mark)....adding the water gets the ice started in the melting process.
Step:5 Leave it alone! Just let it sit until all the ice melts:

Step:6 After all the ice has melted the tea will be incredibly cold and ready to enjoy:

*The result is an incredibly sweet and incredibly refreshing cup that brings out new flavor dimensions in the tea and it is a fun change to the typical hot water brewing method:
