Guarana (Paullinia cupana) is a climbing plant in the maple family, native to the Amazon rainforest. Its seeds contain roughly twice the caffeine concentration of coffee beans, which has made it one of the most commercially important stimulant plants in the world.
In Brazil, guarana-flavoured soft drinks are a cultural staple — Guaraná Antarctica is one of the country’s most popular beverages. Internationally, guarana extract is a key ingredient in energy drinks, supplements, and caffeinated products. The plant has deep roots in Indigenous Amazonian cultures, particularly among the Sateré-Mawé people, who have cultivated and used it for centuries.
Beyond caffeine, guarana seeds contain theobromine and tannins, which contribute to their distinctive slightly bitter, astringent flavour. The seeds are typically processed into a paste or powder before use in beverages and food products.
How it's produced
Guarana is both wild-harvested from Amazonian forests and cultivated on farms, primarily in the Brazilian states of Amazonas and Bahia. Cultivated guarana is grown as a perennial shrub or trained vine, typically in partial shade that mimics its natural forest understorey habitat. Plants begin producing fruit after three to four years and can remain productive for decades.
The ripe fruit splits open to reveal dark seeds partially covered by a white aril — giving them a distinctive eye-like appearance. Seeds are harvested by hand, washed, and then traditionally dry-roasted and ground into a fine powder or formed into sticks of guarana paste. Commercial processing involves drying, shelling, and milling the seeds into extract or powder for use in beverages and supplements.
