Iced Green Tea Recipe

Green iced tea

This iced green tea recipe is made by steeping the tea in cold water for a long time. The flavour of the tea is different when you brew it in cold water. It seems smoother and sweeter. When you are using a good quality green tea, the taste is subtle, delicious and very refreshing.

I prefer to use Sencha green tea for this recipe, but you can of course use any green tea.

The only draw-back is the length of time you need to steep it for. I rather like the subtlety of tea that hasn't been brewed for so long, and I often leave my green tea in the fridge for just a couple of hours. But if you like a full-flavoured tea, you need to leave it in the fridge for around 6 to 8 hours.

Each batch of tea is differently flavoured, so it's difficult to give an exact recipe. Some teas are beautifully sweet just on their own. Sometimes they taste either a little bitter, or sometimes not full enough in flavour.  

In this case, I like to use maple syrup and lemon juice which I add until I feel that the taste is right. So although I've put suggested amounts for those ingredients, do taste first!

Iced Green Tea Recipe

Time: 2-8 hours
Makes: 4 tall glasses


1 1/4 litres (5 cups) cold water
5 tsp of green tea leaves
Optional to taste:
4 tsp lemon juice
4 tsp maple syrup


  • Put the water and the green tea leaves into a large pitcher.

  • Stir it around and and put it in the fridge for 2-8 hours, depending on how strong you like the tea to be.

  • Alternatively, you can brew the tea from hot as with other iced teas. In this case, use just four cups of water, as the volume will be made up by the ice.

  • Empty your kettle and add the four cups of water. Turn it on.

  • In the meantime, put the tea leaves into a teapot.

  • Watch your kettle carefully. As soon as it reaches the boil, turn the kettle off. Leave the water in the kettle and set the timer for 15 minutes. 

  • This will reduce the water to roughly the right temperature. Green tea should not be made with boiling water. Here is more information on how to make the perfect cup of green tea.

  • After 15 minutes, pour the tea over the tea leaves in the teapot, put the lid on and set the timer for three minutes.

  • In the meantime, prepare the pitcher with 12 ice cubes.

  • When the tea is brewed, pour it over the ice cubes through a tea strainer. Leave the tea to cool.

  • When it is cold, put it in the fridge for 45 minutes to cool thoroughly.

  • When you are ready to serve, either the hot brewed or cold brewed tea, you can taste it and add the lemon juice and maple syrup as desired.

Serve with

I like to serve green iced tea with flower ice cubes. Borage is lovely in green iced tea, and mint and lemon are also lovely garnishes to use.

This green iced tea recipe goes particularly well with shortbread cookies, ham sandwiches and cream puffs.
