How to Make Iced Tea: Hot-Brewed vs Cold-Brew Methods
There’s something particularly good about a cold glass of iced tea on a warm day. Whether you like your tea bright and fruity, fresh and minty, or rich and full-bodied, there’s an iced tea version worth discovering.
You don’t need a special iced tea maker or complicated ingredients to get started. A little loose-leaf tea, some water and a jug are all you need. What matters is how you brew it.
Hot water and cold water extract flavour differently, so the method you choose can affect the strength, character and finish of your iced tea. Hot brewing gets the flavour out quickly, while cold brewing takes longer and can produce a gentler result. The right approach also depends on the tea itself.

Here are two ways to make iced tea at home, with tips to help you get the best from each method.
1. How to Make Iced Tea Using Hot Water
If you want iced tea without the long wait, hot brewing is a great place to start. Hot water extracts flavour quickly, so you can brew your tea as usual, let it cool and chill it before serving. You can also brew it a little stronger if you plan to pour it straight over ice.
You’ll need:
- 250 ml water
- One serve of loose-leaf tea, following the recommended amount for your blend
- A heatproof jug
- Plenty of ice
- Optional extras: fresh fruit, citrus or mint
Method:
1. Heat the water to the temperature recommended for your tea. Black tea and many fruit infusions generally suit freshly boiled water, around 100°C. Green tea often benefits from cooler water, around 80 - 90°C.
2. Add the loose-leaf tea and steep according to its brewing instructions. Many fruit infusions need around 5–8 minutes, while green and black teas often need less time.
3. Strain into a heatproof jug and allow the tea to cool.
4. Refrigerate until cold, then pour over a glass full of ice.
5. Add lemon, fresh mint or pieces of fruit if you like.
Short on time? You can pour freshly brewed tea over plenty of ice to chill it quickly. Use a heatproof vessel and remember that the melting ice will dilute the tea, so a stronger brew helps here, too.
A word of warning: If you’re planning to serve the hot tea straight over ice, brew it slightly stronger than you normally would. As the ice melts, it dilutes the tea, so a more concentrated brew helps preserve the flavour.
2. How to Make Cold-Brew Iced Tea
Cold brewing takes a little planning, but very little hands-on effort. Instead of using hot water, you steep the tea in cold water in the fridge for several hours. Depending on the blend, this can produce a gentler flavour with less of the sharpness you might notice in a hot-brewed tea.
You’ll need:
- 1 litre of cold, preferably filtered water
- Loose-leaf tea, using the recommended amount for your blend as a starting point
- A clean jug or bottle with a lid
Method:
- Add the loose-leaf tea to the cold water in your jug.
- Cover and place in the fridge.
- Leave to steep for around 6–12 hours, tasting as you go. The ideal time will depend on the tea and how strong you like it.
- Strain out the tea leaves.
- Pour into a glass over ice and enjoy.
Many fruit infusions, green teas and fragrant herbal blends are worth trying cold-brewed. Black tea can work well, too, although the result will depend on the particular tea and your preferred strength.
The trick: Start with the recommended amount of tea and taste before extending the steep. There’s no single brewing time or quantity that works for every blend, so a little experimentation will help you find your preferred result.
How to Make a Jug of Iced Tea for the Fridge
Once you’ve found a method you love, making a larger batch means you’ll have something refreshing ready whenever you fancy a glass.
For a one-litre batch, you’ll need:
- 1 litre of water for cold brewing, or around 500 ml for a concentrated hot brew, plus extra cold water to top up
- Loose-leaf tea, using the recommended quantity for your blend and adjusting to taste
- Ice for serving
- Optional extras such as lemon, orange slices, berries or mint
Method:
- Choose your tea and decide whether to use the hot-brew or cold-brew method above.
- For a hot-brew concentrate, use around 500 ml of water and increase the amount of tea to suit the smaller volume. Brew according to the tea’s instructions, then strain and allow it to cool before topping up with cold water to make one litre.
- For cold brewing, steep the tea directly in one litre of cold water in the fridge, then strain when the flavour is to your liking.
- Refrigerate the finished tea in a clean, covered jug.
- Serve over fresh ice, adding fruit or herbs if you like.
Keep your iced tea refrigerated at 5°C or below. For best quality, aim to drink it within 2–3 days, and always use clean equipment. Discard it if its appearance, smell or taste changes unexpectedly.
The trick: Add delicate garnishes just before serving. Citrus slices and fresh herbs look lovely in a jug, but leaving them in for days can change the flavour.
How to make iced tea taste even better
A few small adjustments can make a real difference to the finished cup.
Get the strength right. Ice melts and dilutes your tea. Brew a little stronger if you're pouring it straight over ice, or chill the tea first to keep the flavour more concentrated.
Watch your steeping time. Leaving tea to steep for too long can create a bitter or overly astringent flavour. Follow the instructions for your particular blend, then adjust to taste.
Choose your water temperature carefully. Black tea and many fruit infusions generally handle freshly boiled water well. Green tea is often better with cooler water, which can help preserve its more delicate flavour.
Try it before adding sweetener. Some fruit infusions have plenty of naturally sweet, fruity character without anything extra. If you'd like a sweeter drink, add a little sugar or syrup while the tea is still warm so it dissolves easily, then chill.
Keep the additions simple. Lemon, orange, mint, fresh berries and sliced stone fruit can all work beautifully. Start with one or two additions so you can still taste the tea itself.
Don't overlook the ice. Plenty of ice helps keep your drink cold. If you find it dilutes the flavour too quickly, chill the tea thoroughly before serving or use larger ice cubes.
Frequently asked questions about homemade iced tea
Can you make iced tea with any tea?
You can experiment with many different teas, including black, green, white and herbal blends. The flavour will depend on the ingredients and how you brew them. Some blends are specifically designed to be served cold, while others may need a little experimentation to find their best balance.
Is cold-brew iced tea better than hot-brewed iced tea?
Neither method is automatically better. Hot brewing is quicker and can produce a fuller, more immediate flavour. Cold brewing takes longer and often creates a gentler-tasting drink. The best method depends on the tea and the flavour you prefer.
How long does homemade iced tea last in the fridge?
For best quality, aim to drink homemade iced tea within 2 to 6 days when it's prepared hygienically, stored in a clean, covered container and kept at 5°C or below. Don't leave it sitting at room temperature for extended periods, and discard it if anything seems unusual. Green and white teas tend to only last up to 2 to 3 days, because they're more delicate they tend to lose flavor or turn grassy quickly. Whereas a black ice tea can last up to 4 to 6 days.
Do you need to add sugar to iced tea?
Not at all. Many fruit and herbal infusions have plenty of flavour without added sweetener. If you prefer a sweeter drink, start with a small amount and adjust to taste. You can also try adding fresh fruit or citrus for extra character.
Find your next favourite iced tea
Making iced tea at home is a simple way to get more from the tea you already love. Brew it hot when you want something quickly, cold-brew a jug overnight, or make a batch to keep in the fridge for the next warm afternoon.
Start with a flavour you enjoy, experiment with the brewing method, and keep the additions simple. You might discover that your favourite iced tea is a blend you’d never thought to serve cold.
