Watch the colour before you taste anything. A French press shot of rooibos espresso settles into a deep, ruby-red pour with a soft, golden crema and real weight behind it. Getting there takes a fine-to-medium grind, a full four-minute steep in water just off the boil, and a slow, deliberate plunge. It will not look identical to a machine-pulled shot, the crema is softer and the body a touch rounder, and it is a genuine espresso preparation in its own right.
Why the French press works for rooibos
Rooibos gives up its depth slowly. The plant's needle-thin leaves come from South Africa's Cederberg mountains, milled fine, and a full-immersion method suits that pace far better than a rushed pull ever could. Rush it, and the cup turns thin and flat, missing the body a proper steep builds. A French press hands the grounds the time they need. What comes back is a shot with real weight on the tongue.
You pour Roi into the French press, finely milled and ready to go, sieved at source so you get the same full body, cup after cup. Your grinder stays in the cupboard, one consistent grind built for full immersion every time. If you want the full walkthrough across every brew method, see our guide on how to make rooibos espresso.
Dosing and water temperature
Start with 2 to 3 teaspoons, around 15 grams, of ground rooibos per 200ml of water. Heat your water until it is just off the boil, roughly 96 to 98 degrees Celsius. A full rolling boil can scorch the finer particles and pull out a flatter, more bitter note, while water that is too cool under-extracts and leaves the shot thin.
Steep time and why it is longer than coffee
Pour the water over the grounds, stir gently to make sure everything is saturated, and rest the plunger on top without pressing down. This traps the heat while the rooibos steeps. Give it five to ten minutes, considerably longer than a coffee press, because rooibos releases its depth more slowly than roasted coffee does. Four minutes is the minimum for genuine body, and pushing toward the ten-minute mark gives you a richer, more rounded cup if that is the style you are after.
Reading the steep
Watch the colour deepen in the glass. What starts as a pale amber will darken into a rich, ruby-red liquid by the time you are ready to plunge. That colour shift is your best real-time signal that extraction is on track, more reliable than a timer alone.
The plunge technique
Press the plunger down slowly and steadily, over ten to fifteen seconds rather than one firm push. Rooibos grounds compress differently to coffee. Push too hard or too fast, and they clog the mesh. A gentle, even pressure keeps the flow clean and keeps grit out of your cup. If you feel real resistance partway down, ease off, let the pressure settle, then continue. If you're just getting started, our herbal espresso starter pack with French press has everything set up for this exact technique.
What the crema and body look like
A French press shot will not build the tight, lasting crema you get from a pressurised espresso machine, that microfoam depends on forced pressure through a fine portafilter basket. What you get here is its own thing, a looser, golden-toned layer on top sitting over a fuller-bodied liquid, built by a longer steep that draws more out of the leaf. Side by side, the machine shot runs sharper and more concentrated. The French press version runs rounder and softer on the palate, closer to a rich, full-bodied pour than a tight double shot. Both are legitimate expressions of the same single-origin ingredient.
Serving your French press shot
Drink it neat in a small cup to taste the depth on its own, or stretch it with steamed milk for something longer. Whether it is the moka pot, the machine, or the press, slow down, measure with intention, and let the process do the work. A ritual worth keeping.

Frequently asked questions
Can you brew espresso in a French press?
Yes, a French press is a legitimate full-immersion method for pulling a concentrated, full-bodied shot. It will not replicate the tight crema of a pressurised machine, but the depth and body hold up well, especially with a grind and steep time suited to the ingredient.
What is rooibos espresso?
Rooibos espresso is a concentrated shot of finely milled, single-origin rooibos, pulled or steeped to produce a full-bodied, ruby-toned cup with real depth. Roi uses single-origin rooibos from the Cederberg, ground specifically for espresso-style extraction, and it is naturally caffeine-free.
How many scoops of rooibos do you put in a French press?
Use around 2 to 3 teaspoons, roughly 15 grams, per 200ml of water. That ratio holds for a single serve, and you can scale it up proportionally for a larger press.
How long should rooibos steep in a French press?
Give it five to ten minutes rather than the shorter steep you would use for coffee. Rooibos releases its depth more gradually, so four minutes is the floor for real body, and longer steeps build a richer cup.
Does a French press rooibos shot taste different to a machine-pulled one?
Yes, though both are genuine. The machine version is sharper and more concentrated with a tighter crema, while the French press version is rounder and fuller-bodied thanks to the longer steep. Both are genuine expressions of the same single-origin rooibos, drawing depth out of the leaf in different ways.
