Field Guide No. 001 — Ilex guayusa
Every guayusa tea sold in the US, catalogued and compared.
Guayusa is an Amazonian holly leaf brewed by Kichwa communities for centuries — naturally caffeinated, smoother than coffee, without the crash of a sugared energy drink. This guide specimens every US-market guayusa product side by side: format, caffeine, origin, certifications, and how it actually tastes.
