Guaraná
Paullinia cupana · Sapindaceae · also known as Guarana, Brazilian cocoa, Uaraná
An Amazonian climbing vine whose red fruit splits to reveal a black seed in white flesh — looking uncannily like an eye. The caffeine-packed seed powers Brazil's national soft drink and the global energy-drink industry.

A ripe guaraná fruit looks startlingly like a human eye — a red shell opening around a white aril with a black seed at its center — which is exactly what the Sateré-Mawé origin myth describes: the eyes of a beloved child planted in the forest.

How to select & store
Picking a ripe one
The fresh fruit is rarely sold; most guaraná reaches people as powder, syrup, or soda. For powder, choose fresh, tan, earthy-smelling guaraná, not stale or musty.
Storing it
Dried, roasted guaraná powder and traditional hard "bastão" sticks keep for a very long time — one reason the Amazonian Sateré-Mawé people historically made and traded it as sticks grated on demand.

Eating guaraná: what to know
What regular consumption looks like
Guaraná is mostly water with natural sugars, a little fibre, and assorted micronutrients — a hydrating everyday addition to your overall fruit intake rather than a standout for any one nutrient.
Sensible amounts
A typical fruit serving is roughly a handful, one medium fruit, or about 80 g, and two or more varied fruit servings a day is a sensible everyday pattern.
Evidence & conditions
As a whole fruit, Guaraná contributes fibre, vitamins, and beneficial plant compounds, but it has not been shown to treat or prevent any specific condition — so it is best enjoyed as part of a healthy diet rather than as a remedy.

Few fruits are as instantly recognizable as a ripe guaraná: the red capsule splits open on the vine to reveal a single black seed set in white flesh, looking uncannily like a human eye. For the Sateré-Mawé people of the Amazon, who first domesticated the vine, that resemblance is no accident — their origin myth describes the eyes of a beloved child planted in the forest.
The caffeine capital
The fruit’s pulp is a minor food; the seed is the treasure. Roasted and ground, it’s one of the most caffeine-rich plant materials on earth — several times the strength of a coffee bean by weight — with a bitter, earthy, faintly chocolatey character. That potency built an industry: guaraná is the flavor and kick behind Brazil’s beloved national soft drink (Guaraná Antarctica) and a global staple of energy drinks and supplements. The Sateré-Mawé still make it the traditional way, pressing the roasted seeds into hard sticks (bastão) grated on demand into water. The town of Maués in the Amazon is its capital, celebrating the harvest each year. Potent, sacred, and unmistakable, guaraná is the Amazon’s gift to the world’s caffeine habit. For its fellow Amazonian energizers, see açaí and cupuaçu.
