About one in every four soft drinks sold in Brazil is this single brand — made from an Amazonian berry with roughly triple the caffeine of a coffee bean.
Guaraná Antarctica is a bright, fruity soda flavored with guaraná, a caffeine-rich seed native to the Amazon that Indigenous Brazilians used long before it became a soft drink. It's sold in every corner bar, beach kiosk, and street-food stand nationwide, usually ice-cold.
