What you'll love about the recipe

  • Rooibos (or redbush) tea is naturally caffeine-free so you can drink it at any time of day, and it's ideal for children
  • Rooibos is low in tannins, which can make other teas taste bitter and interfere with mineral absorption. It is ideal for drinking cold. You can keep a jug of iced tea in the fridge and top it up throughout the day, and it will still taste delicious
  • No added sugar. Unlike many soft drinks, this iced rooibos tea recipe is designed to be drunk unsweetened. Rooibos has a full-bodied, rich, slightly sweet flavour which works very well as a refreshing summer drink
  • It's healthy. Rooibos tea, made from a South African shrub called Aspalathus linearis, is rich in antioxidants and polyphenols. Orange and cinnamon are also a natural source of antioxidants
  • Quick and easy to make, iced red tea has just 3 ingredients. It's perfect for entertaining, served in a big pitcher

Ingredients

Rooibos tea bags, orange and cinnamon.

Rooibos tea. I use tea bags to make iced rooibos tea as it won't need straining, but you can use loose leaf tea if you prefer. One teaspoon of loose leaf tea is the equivalent of one tea bag.

Adding a piece of fresh orange to homemade rooibos iced tea naturally sweetens it slightly, and I love the flavour of orange and rooibos together.

Cinnamon. A cinnamon stick is ideal for this recipe. Half a cinnamon stick is sufficient; you can reuse it several times. If you don't like cinnamon, you could also use other warming spices such as cloves, cardamom, ginger or star anise.

How to make iced rooibos tea

All you'll need to prepare your perfect iced rooibos tea is a heat-proof jug and some boiling water.

Pour the boiling water over the tea bags and add the slice of orange and cinnamon stick. Leave the tea bags in the liquid until you are ready to serve. Unlike other teas, I find that rooibos tea does not go bitter even if you brew it for a long period of time.

Leave to cool. If you place it in the fridge, it'll reach room temperature in about an hour.

Serve over ice with an extra slice of orange.

Cold Brew Method Iced Rooibos

Alternatively, you can cold brew rooibos tea to drink chilled. Cold brew rooibos has a slightly smoother, sweeter flavour than hot-brewed, although it's quite a subtle difference.

You'll need to use twice the number of teabags or loose leaf tea and cinnamon when cold brewing to get a good depth of flavour.

Leave the tea to infuse in the fridge for about 8 hours, or overnight.

Strain out the teabags and cinnamon when you are ready to drink and add a fresh slice of orange and ice.

Flavour variations

If you want to add extra sweetness to your redbush tea drink, try a spoonful of honey or maple syrup. You could also add some vanilla extract for a slightly sweeter flavour.

I've added orange to this caffeine-free iced tea recipe, but you could also use other fruits

  • A small handful of raspberries or strawberries add a beautiful colour and a sweet, summery berry flavour
  • This recipe is a great way to make a healthier sugar-free peach iced tea. Thinly slice half a juicy ripe peach and add to the mix (you can add the peaches to a cold-brewed tea as well as hot)
  • A few slices of apple also complement iced rooibos tea perfectly

You can also add a spring of mint and a slice of lemon in place of the orange if preferred.

For a sparkling iced tea, top up with some sparkling water. Brew the tea (hot or cold) with half the quantity of water in the recipe to make a more concentrated infusion. Then dilute the drink with an equal amount of sparkling water.

Recipe tips

If you are a big rooibos iced tea drinker, you can top the jug up once or twice during the day. Just add some more boiling water and place it back in the fridge. I find it tastes just as nice on the second or third brew. Discard the tea bags at the end of the day.

Double or triple the recipe as needed for entertaining. If you want to make large batch for a party, I think it's easiest to cold brew the tea overnight. It's great for barbecues as both kids and adults enjoy this caffeine-free, sugar-free drink.

Leftover tea can be stored in the fridge for up to 2 days.

Frequently asked questions

Can you make rooibos tea with cold water?

Yes, you can make rooibos tea with cold water (cold brewed). But you'll need to use double the quantity of tea bags and infuse the tea for 8-12 hours.

What is the best time to drink rooibos tea?

As rooibos tea is naturally caffeine-free, it can be drunk at any time of the day. It is also low in tannins, which means it won't interfere with the absorption of minerals such as iron and can be safely drunk with meals.

Can you steep rooibos twice?

Unlike many other teas, rooibos doesn't contain bitter-tasting tannins. That means that it can be brewed for a longer period of time. I regularly re-steep my rooibos tea bags once or twice, and I do the same when I make iced rooibos tea too.
