How to Make Rooibos in a French Press: A Better, Fuller Brew
By Rooibrew Team
Your French Press Is Better at Tea Than You Think
A French press usually lives next to the coffee grinder, but it is also one of the easiest ways to brew excellent loose-leaf rooibos. The wide chamber gives the fine rooibos needles room to circulate, the mesh filter keeps most of them out of your cup, and the plunger makes serving clean and simple.
More importantly, a French press produces a full, flavourful infusion. Rooibos is naturally caffeine-free and low in tannins, so it can steep longer than black or green tea without turning aggressively bitter. That makes this method forgiving enough for a weekday mug and precise enough for a proper tea ritual.
Here is how to make rooibos in a French press, plus a few ways to turn the same brew into a latte, iced tea, or stronger cafe-style drink.
The Best Rooibos-to-Water Ratio
For a balanced everyday cup, use:
- 2 teaspoons loose-leaf rooibos per 250 ml water
- Freshly boiled water at about 95-100°C
- A steeping time of 5-7 minutes
For a standard 1-litre French press, use roughly 8 teaspoons of rooibos. If your press is labelled by “cups,” check its actual volume: a French press cup is often much smaller than a normal mug.
Rooibos rewards a generous dose. Using too little leaf and extending the steep will usually create a thin, woody drink rather than a richer one. Start with enough rooibos, then adjust the strength by a teaspoon on your next brew.
How to Make Rooibos Tea in a French Press
1. Preheat the Press
Rinse the glass chamber with hot water, swirl it briefly, then pour the water away. Preheating prevents a cold press from pulling heat out of the brew, especially when you are making only one or two cups.
2. Add Loose Rooibos
Place 2 teaspoons of rooibos in the press for every 250 ml of water. Shake the press gently so the leaves form an even layer.
Loose rooibos consists of small needle-like pieces, so a fine mesh plunger works best. A few tiny particles may still pass into the cup. They are harmless, but you can pour through a small tea strainer if you prefer a perfectly clear drink.
3. Pour Freshly Boiled Water
Pour the water evenly over the rooibos. Unlike delicate green tea, rooibos handles boiling water well. The high temperature helps extract its deep red colour and naturally sweet, rounded flavour.
Give it one gentle stir to wet all the leaves, then place the lid on top without pressing the plunger down.
4. Steep for 5-7 Minutes
Five minutes gives a lighter, cleaner cup. Seven minutes creates more body and deeper caramel, honey, and woody notes. You can leave it for 8-10 minutes if you like a very strong brew or plan to add milk.
Rooibos does not become sharply astringent in the way over-steeped black tea can, but an extremely long infusion may taste flat. More time is useful; all afternoon is not.
5. Press Slowly and Pour
Push the plunger down with slow, steady pressure. If it resists, lift it slightly and try again rather than forcing it. Pour all the tea once it is pressed. Leaving brewed rooibos sitting on the leaves will keep extracting flavour and can make the final cup heavier than the first.
How to Make Strong French Press Rooibos for Milk
Milk needs a concentrated base. For a French press rooibos latte, double the normal dose and reduce the water:
- 4 teaspoons loose rooibos
- 150 ml boiling water
- 8-10 minutes steeping time
- 150 ml hot, frothed milk
Brew, press, and pour the concentrate into a large cup. Add steamed dairy or barista oat milk, then finish with cinnamon or a small amount of vanilla if you want it sweeter.
This creates a smooth red latte without an espresso machine. It will be softer than pressure-extracted rooibos espresso, but it still has enough body to stand up to milk. If you want the denser cafe version, Rooibrew is ground for espresso-style extraction and works in espresso machines, moka pots, and AeroPress brewers.
Can You Cold Brew Rooibos in a French Press?
Yes. A French press is particularly convenient for cold brew because the brewing vessel and filter are already combined.
Add 3 teaspoons of rooibos per 250 ml cold water, stir, cover, and refrigerate for 8-12 hours. Press slowly, then pour the tea over ice. Add lemon, orange peel, fresh mint, or a splash of sparkling water.
Cold water extracts rooibos more gently, producing a smooth and naturally sweet drink with less of its earthy edge. Make a full press in the evening and it will be ready for breakfast.
Common French Press Rooibos Mistakes
Using Too Little Rooibos
Weak rooibos is usually a dosing problem, not a steeping problem. Use 2 teaspoons per 250 ml before extending the brew time.
Pressing Too Early
Rooibos needs at least five minutes to develop its full colour and flavour. The water may turn red quickly, but colour alone does not mean the brew is ready.
Using an Oily Coffee Press
Coffee oils cling to the mesh and can make rooibos taste stale or smoky. Take the plunger apart and clean each section with warm soapy water. If you regularly brew both drinks, a separate small press for tea is worth considering.
Leaving Tea in the Press
Serve the whole batch after plunging. If you make more than you need, transfer the rest to a thermos or jug rather than leaving it on the leaves.
French Press vs Teapot for Rooibos
A teapot remains a lovely way to brew rooibos, particularly when it has a fine built-in infuser. The French press wins on visibility and control: you can watch the leaves circulate, stop them with one movement, and brew enough for several cups without handling a separate strainer.
It is also versatile. The same press can make hot rooibos, concentrated latte bases, and overnight cold brew. For anyone trying loose-leaf rooibos for the first time, it may be the most useful equipment already sitting in the kitchen.
A Simple Method Worth Keeping
Making rooibos in a French press is not a workaround. It is a genuinely good brewing method: 2 teaspoons per 250 ml, freshly boiled water, and 5-7 minutes for a rich everyday cup.
Use more leaf for milk drinks, cold brew it overnight for summer, and clean the filter thoroughly between coffee and tea. The result is smooth, full-bodied, naturally caffeine-free rooibos with almost no fuss.
