Buchu
A Cape fynbos shrub whose small leaves smell startlingly of blackcurrant and mint, infused in South Africa and used to flavour brandy and, later, soft drinks. Two species are traded under the name and the distinction between them is a commercial grade rather than a technicality.
Identity
- Botanical name
- Agathosma betulina
- Family
- Rutaceae
- Part used
- Leaf
- Origin
- The Cederberg and western Cape fynbos, South Africa — mountain slope, on sandstone
- Drunk in
- Western Cape, Cederberg, South Africa
Character
Sharp, blackcurrant-like and minty with a resinous bitterness behind it, and strong enough that it is nearly always a small part of a blend rather than a cup of its own.
Notes: blackcurrant, mint, resin, cat’s tongue
History
Long used by the Khoikhoi and San of the western Cape, recorded by European visitors from the eighteenth century and exported to Britain in the nineteenth as a Cape commodity. Boegoebrandewyn — the leaf steeped in brandy — is a Cape household preparation with a continuous history. Pressure on wild stands has been a persistent management problem and cultivation has expanded in response.
How it is drunk
Infused domestically in the western Cape and sold in South Africa alongside rooibos and honeybush, though at a small fraction of their volume. Its widest reach is as a flavouring: it is one of the aromatics behind blackcurrant-scented drinks, and a South African soft drink is built on it.
Production
Leaves are harvested in summer, dried, and often distilled for oil rather than sold whole — the oil trade is larger than the tisane trade. The oil glands are visible as translucent dots when a leaf is held to the light, which is the standard field check and works on dried material too.
Preparation
Infusion · Blended with tea
Herbal infusion (tisane)
1–2 g/100 ml · 90–95 °C · 4 min
Category-typical practice rather than a measurement for this specific botanical. Most infusions are far more tolerant of a long steep than tea is.
What gets confused
Agathosma betulina (round-leaf) and A. crenulata (oval-leaf) are both sold as buchu, look similar dried and are priced differently. Older literature and much of the trade still use the genus name Barosma. Wild-harvested and cultivated material are both on the market and are not distinguished on most labels.
Common mistakes
- Dosing it like rooibos. A pinch is a blend component; a spoonful takes over the pot.
Evidence for this page
This page is TeaHQ synthesis throughout. No external source stands behind any statement on it, including the botanical name. 132 of the 204 botanicals have had their names and distribution checked against a taxonomic authority and this is not one of them.
Brewing parameters here are typical practice for the category rather than measurements of this plant, and each set says so.
This page makes no safety claim. It describes what Buchu is, where it comes from and how it is prepared — not what it does to a person. The absence of a safety note here is not a statement that the plant is safe. How TeaHQ handles this.
