How to Make a Rooibos Latte at Home (the Caffeine-Free Coffee Substitute That Actually Works)
Rooibos is a caffeine-free herbal "tea" from South Africa. It's not actually tea — it comes from a legume shrub, not from Camellia sinensis — but it's been brewed and consumed like tea for over 300 years. The cup is naturally sweet, slightly woody, with notes of honey, vanilla, and a mild red-brown color.
A rooibos latte is the same drink as a coffee latte, but with brewed rooibos standing in for the espresso. The result is a sweet, creamy, caffeine-free cup that works well as an evening drink, a coffee alternative for people who can't have caffeine, or simply a different kind of morning ritual.
This is how to make a rooibos latte at home in 5 minutes, plus the brewing details that make the difference between a flat cup and a good one.
What rooibos actually is
Rooibos (pronounced ROY-boss) is the Afrikaans name for a legume shrub native to the Cederberg region of South Africa, about 200 km north of Cape Town. The botanical name is Aspalathus linearis. The plant is not related to the tea plant (Camellia sinensis) but the leaves are processed in a way that produces a tea-like brew.
The processing is similar to black tea in some ways. The fresh green leaves and stems are cut, bruised, and left to oxidize in the sun for several hours. During oxidation, the leaves turn from green to the characteristic red-brown color. After oxidation, the leaves are dried in the sun, sorted, and packaged.
The result is a brew that is naturally caffeine-free, low in tannins, and rich in antioxidants (particularly aspalathin and nothofagin, which are unique to rooibos and not found in true tea).
The flavor is sweet, slightly woody, with notes of honey, vanilla, and a mild earthy character. There's no bitterness and very little astringency. The cup is sometimes compared to a mild black tea, but without the caffeine and without the tannic bite.
Rooibos has been consumed in South Africa for centuries. It became internationally popular in the 20th century, particularly in Germany, the UK, the Netherlands, and Japan. It's now widely available in most tea markets, including the US.
There are two main types of rooibos:
Red rooibos. The standard, oxidized form. Reddish-brown leaves with a sweet, full-bodied cup.
Green rooibos. An unoxidized form. Lighter, greener leaves with a more grassy, less sweet cup. Green rooibos is rarer and more expensive.
For a latte, red rooibos is the standard choice. Green rooibos works but produces a less rich, less sweet cup.
Why a rooibos latte works
A rooibos latte is built on the same structure as a coffee latte — strong brewed base + steamed milk + optional sweetener — but with a different base.
A few reasons it works particularly well as a latte.
Naturally sweet. Rooibos has a built-in sweetness that comes from the plant, not from added sugar. When you add milk, the sweetness carries through.
No bitterness. Unlike coffee, rooibos has no bitterness to mask. The cup stays smooth even when brewed strong.
Low astringency. Rooibos has very low tannin content, so the cup is never puckering. Milk and rooibos complement each other without competing.
Caffeine-free. A rooibos latte is a true caffeine-free drink, suitable for evenings, pregnancy, or anyone avoiding caffeine.
Forgiving of brewing variables. Rooibos is hard to over-extract. Brewing it too long or too hot doesn't make it bitter, just stronger. This makes it easier to get a good cup than coffee.
Inexpensive. A pound of rooibos costs less than a pound of most true teas, and a single latte uses only 4 to 6 grams. A 250g bag makes 40 to 60 lattes.
What you need
Loose rooibos or rooibos tea bags. Loose rooibos is generally better — the leaves are larger and more flavorful. Tea bags work fine and are more convenient. Get a rooibos that's labeled as "superior grade" or "long cut" if possible — the finer cut rooibos tends to brew dustier and less sweet.
Milk of choice. Whole dairy milk produces the creamiest, most coffee-shop-style cup. Oat milk is the most popular dairy-free alternative and steams similarly. Almond milk and soy milk also work but are less creamy. Coconut milk is too strongly flavored for most palates.
Sweetener (optional). Rooibos is naturally sweet, so most people don't add anything. If you want a sweeter cup, honey, maple syrup, or simple syrup all work. Vanilla syrup (the coffee-shop style) is also a good option.
A small pot or kettle. For brewing the rooibos concentrate. A stovetop pot, electric kettle, or even a microwave-safe container works.
A way to froth or steam the milk. Options include:
- A French press (pour hot milk in, pump the plunger up and down for 30 seconds)
- A handheld milk frother (inexpensive, works well)
- A standalone milk steamer (if you have an espresso machine)
- A jar with a lid (shake hot milk vigorously for 30 seconds)
- A whisk (works in a pinch)
For a 5-minute version, the handheld frother or the French press method is the easiest.
The 5-minute recipe
Step 1: Brew the rooibos concentrate.
Bring 1 cup (240 ml) of water to a boil. Add 2 tablespoons (about 6 grams) of loose rooibos or 2 rooibos tea bags to a small pot. Pour the boiling water over the rooibos. Reduce heat to low and simmer for 4 to 5 minutes — longer than you would for drinking rooibos plain, because you're making a concentrate that will be diluted with milk.
The brew should turn a deep reddish-brown, similar to a strong black tea. Strain out the leaves (or remove the tea bags) and set the concentrate aside.
Step 2: Heat and froth the milk.
In a separate small pot or in a microwave-safe container, heat 1 cup (240 ml) of milk to about 150°F (65°C). The milk should be hot but not boiling — you'll see a thin skin form on top when it's ready.
Pour the hot milk into a French press or a deep jar. Pump the plunger or shake the jar vigorously for 20 to 30 seconds, until the milk has roughly doubled in volume and has a thick, foamy top.
Or use a handheld milk frother: hold it at the surface of the milk and move it up and down for 20 to 30 seconds, until the milk is foamy.
Step 3: Combine.
Pour the rooibos concentrate into a large mug (12 to 16 oz). Pour the frothed milk over the concentrate, holding back the foam with a spoon if you want a layered look. Spoon the foam on top.
Step 4: Sweeten (optional).
Add 1 to 2 teaspoons of honey, maple syrup, or vanilla syrup, to taste. Stir. Most rooibos lattes don't need sweetener, but adjust to your preference.
Step 5: Optional toppings.
A sprinkle of cinnamon, a dusting of cocoa powder, or a few drops of vanilla extract all work. Keep it simple — rooibos doesn't need much.
The iced version
For a cold rooibos latte, the process is similar but with cold milk and cold brew instead of hot.
Step 1: Cold brew the rooibos concentrate.
Add 2 tablespoons (6 grams) of loose rooibos to 1 cup (240 ml) of cold water in a jar or pitcher. Refrigerate for 6 to 8 hours, or overnight. Strain out the leaves.
Step 2: Pour and dilute.
Fill a glass with ice. Pour in 1/2 cup of the cold-brewed rooibos concentrate. Add 1/2 cup of cold milk. Stir.
Step 3: Sweeten and serve.
Add sweetener to taste, if using. Stir and serve immediately.
The cold-brewed version is sweeter and less woody than the hot-brewed version. The cold water extracts the sweet notes more slowly and leaves some of the woodier notes behind.
Variations to try
Vanilla rooibos latte. Add 1/4 teaspoon of vanilla extract to the concentrate before combining with milk. Or use vanilla syrup as the sweetener.
Honey rooibos latte. Use honey as the sweetener and add a pinch of cinnamon on top. The honey notes complement rooibos's natural sweetness.
Spiced rooibos latte. Add a pinch of ground cinnamon, a pinch of ground cardamom, and a small piece of fresh ginger to the concentrate while it's simmering. Strain before combining with milk. The result is a chai-like cup without the caffeine.
Chocolate rooibos latte. Add 1 tablespoon of cocoa powder to the concentrate while it's simmering. Strain before combining with milk. The chocolate notes complement rooibos's woody sweetness.
Dirty rooibos latte (with espresso). Pour a single shot of espresso into the mug before adding the rooibos concentrate. The combination is a coffee-and-rooibos hybrid, with the espresso's bitterness and the rooibos's sweetness playing off each other. Note that this adds caffeine.
How it compares to other lattes
The rooibos latte has its own character, distinct from other non-coffee lattes.
Versus a matcha latte. Matcha lattes are green, slightly bitter, and contain caffeine. Rooibos lattes are red-brown, naturally sweet, and caffeine-free. They serve different purposes.
Versus a chai latte. Chai lattes are spiced, with notes of cinnamon, cardamom, and clove. Rooibos lattes are simpler, with a honey-wood character and no spice. If you want chai spices, add them to the rooibos latte as in the spiced variation above.
Versus a turmeric latte (golden milk). Turmeric lattes are earthy, with a distinct turmeric note. Rooibos lattes are sweeter, less earthy. They're different drinks for different moods.
Versus a coffee latte with decaf. Decaf coffee lattes taste like coffee but without caffeine. Rooibos lattes don't taste like coffee at all. If you want a non-coffee, non-caffeinated hot drink, rooibos is the closer fit.
Common mistakes to avoid
Brewing too weak. A rooibos latte needs a strong concentrate to stand up to the milk. Use 6 grams of rooibos per cup of water and simmer for 4 to 5 minutes. Don't try to brew it the same strength as drinking rooibos plain.
Brewing too short. Rooibos doesn't extract quickly. A 30-second steeping produces a thin, watery cup. Give it at least 4 to 5 minutes for a proper concentrate.
Using too much milk. A latte is not a milkshake. The ratio should be roughly 1 part concentrate to 1 part milk. If the cup is mostly milk, it's not a latte — it's warm milk with rooibos.
Overheating the milk. Milk above 160°F (71°C) develops a cooked, slightly burnt flavor. Heat to 150°F (65°C) for the best texture and taste.
Skipping the foam. A latte is defined by the foam. If you don't froth or steam the milk, you have a rooibos-and-milk, not a rooibos latte.
The honest take
A rooibos latte is a good drink. It's sweet, soothing, and easy to make. It's not a replacement for coffee if you love coffee — it's a different drink for different moments.
If you're looking for an evening drink that doesn't keep you up, a caffeine-free alternative to your afternoon coffee, or a coffee-adjacent drink for kids or pregnant friends, a rooibos latte is one of the better options. The cup is mild, the prep is forgiving, and the cost is low.
If you're a serious coffee person who needs the bitterness and complexity of espresso, a rooibos latte will probably feel thin. Make it once, see what you think, and adjust.
Where to find good rooibos
If you want to try a rooibos latte, the rooibos you use matters less than you might think. Most rooibos on the market is similar in quality. Look for:
Long-cut or superior grade rooibos. Larger leaves brew a cleaner cup. The finely cut "tea bag" grade rooibos tends to brew dustier.
Single-origin rooibos. Rooibos from the Cederberg region of South Africa is the standard. There are also small amounts of rooibos grown in other countries, but the South African rooibos is the original and most consistent.
Avoid flavored rooibos for lattes. Vanilla-flavored, caramel-flavored, and other flavored rooibos teas are designed for drinking plain. They often clash with milk. Use plain rooibos for lattes and add your own flavoring.
We may add a rooibos option in 2027, particularly a single-origin Cederberg lot. For now, this post is educational — the kind of recipe we'd recommend if you want to try caffeine-free lattes at home.
