When the warm days arrive, nothing beats a tall glass of homemade iced tea — chilled, lightly fragrant and, above all, without the mountain of sugar you find in bottled versions. The good news: making it at home is easier than you'd think, cheaper and infinitely tastier. In this guide I'll walk you through the two methods that work every time (including the famous cold brew), share my foolproof base recipe, then give you five variations to enjoy all summer long.
Why make your own iced tea?
Store-bought iced tea has one big flaw: it's usually very sweet, sometimes artificially flavoured, and the tea itself barely comes through. Making it yourself puts you in charge of three key things: the quality of the tea, the strength of the brew and the amount of sugar (which you can simply leave out). Homemade iced tea costs just pennies a glass, creates no plastic bottles and leaves you free to play with fruit, fresh herbs and spices.
It's also a lovely way to enjoy your favourite teas and infusions in a new form. A delicate green tea, a smooth caffeine-free rooibos or a fruity herbal infusion all lend themselves beautifully to cold steeping.
Cold brew or classic steeping: two methods
There are two main ways to make iced tea. The results aren't quite the same, and each has its merits.
The cold brew method (cold steeping)
Cold brew means steeping the tea directly in cold water for several hours in the fridge. Cold water draws out the aromas slowly without releasing the bitter tannins, giving you a remarkably smooth iced tea that's naturally less astringent and less bitter, even without sugar. It's my favourite method for green tea and scented teas, which reveal all their finesse this way. The only “downside”: you need to plan ahead, as steeping takes 6 to 12 hours.
The quick classic method
In a hurry? Brew your tea hot as usual, using twice as much leaf as for a regular cup (the brew will be diluted by the ice), then pour it straight over a generous amount of ice. This thermal shock locks in the aromas and chills the drink in seconds. The taste is bolder and more tannic than cold brew — ideal if you like a punchy iced tea, especially with a black tea.
The basic homemade iced tea recipe
Here's my cold brew recipe, deliberately neutral: it's the canvas you'll personalise next. Make a big jug to last the whole day.
- 1 litre of cold water (filtered if possible)
- 3 teaspoons of loose-leaf tea (green, black, rooibos or an infusion of your choice), or 4 tea bags
- A few lemon slices
- Ice cubes to serve
- Optional: 1 teaspoon of honey or agave syrup, and fresh mint leaves
Pour the cold water into a jug, add the tea (loose in an infuser, or in bags), cover and refrigerate for 6 to 12 hours. Remove the tea, add the lemon and mint, then serve over ice. The iced tea keeps for 48 hours in the fridge.
5 iced tea ideas to enjoy all summer
Once you've nailed the method, it's time to get creative. Here are five variations that work wonderfully.
1. Green tea, mint and lemon
The great refreshing classic. A cold-brewed green tea, a generous handful of fresh mint and the juice of half a lemon. Thirst-quenching and very light — perfect after a workout.
2. Rooibos, peach and vanilla
Caffeine-free, so perfect for the evening or for children. Cold-steep a rooibos with chunks of fresh peach and a split vanilla pod. Naturally sweet, it needs nothing added. For a richer, creamier version, take a look at our rooibos latte recipe.
3. Sparkling iced matcha
Whisk 1 teaspoon of ceremonial matcha with a little cold water using a bamboo chasen, top up with sparkling water and serve over ice. Energising, with a vivid green colour. If you prefer the creamy version, follow our homemade matcha latte recipe.
4. Hibiscus and raspberry
A hibiscus infusion takes on a gorgeous ruby colour and a tangy taste. Add a few crushed raspberries and a squeeze of lime: it's the most photogenic iced tea of the summer, full of colour without a single dye.
5. Sugar-free fruity iced tea
Reach for a fruity herbal infusion (red berries, citrus, apple-cinnamon) steeped cold: the dried fruit releases enough natural sweetness to skip added sugar entirely. To keep the freshness going on the milky side, check out our iced lattes for summer.
My tips for a great iced tea
A few details make all the difference. First, don't over-steep a hot-brewed iced tea: bitterness stands out even more once the drink is cold. Next, think about flavoured ice cubes: freeze water with pieces of fruit or mint leaves to flavour the drink without diluting it. Finally, if you want it sweet, go for a homemade syrup dissolved while warm (sugar mixes poorly in a cold drink) or, better still, let the fruit do the work.
As for equipment, a simple jug and an infuser are all you need. For iced matcha, a bamboo chasen remains the ideal ally for a lump-free froth.
Frequently asked questions about homemade iced tea
How long does homemade iced tea keep?
In the fridge, in a covered jug, your iced tea will keep for about 48 hours. After that the aromas fade and the freshness is past its best. It's better to make smaller batches and refresh them regularly.
Which tea should I choose for iced tea?
Every tea works in iced form. Green tea and rooibos make smooth, thirst-quenching drinks, black tea gives a bolder result, and fruity or floral infusions (hibiscus, red berries) bring colour and indulgence with no caffeine.
Does cold brew contain less caffeine?
Cold steeping extracts caffeine more slowly, so a short cold brew generally contains slightly less than an equivalent hot infusion. For a completely caffeine-free drink, simply choose a rooibos or a herbal infusion.
How do I sweeten iced tea without sediment at the bottom of the glass?
Granulated sugar dissolves poorly in the cold. Make a simple syrup (sugar melted in a little hot water) to add once cooled, use liquid honey, or steep naturally sweet fruit such as peach or raspberry.
With these two methods and these five variations, you've got everything you need to enjoy homemade iced tea all summer without ever getting bored. Over to you: pick your favourite tea, let it steep, and enjoy a fresh, wholesome, full-flavoured drink.
