Overview

A desk, a gym bag or a trail is where an unsweetened bottle of yerba mate gets used, according to the recommended uses for exercise and for work. Guayaki makes it from organic brewed yerba mate.

Yerba mate is the source of the caffeine, and unsweetened means no sugar to offset the bitter side. The listing mentions increased energy and ethical sourcing. The liquid contents field calls it a fruit juice drink, which looks like an error.

Who it's for

Yerba mate fans who want an unsweetened bottled tea for work or exercise. Anyone who prefers a sweetened or fruit-flavored drink, or who avoids caffeine, should look elsewhere.

Pros and cons

Performance notes

Brewed yerba mate supplies the caffeine, and with no sweetener the taste stays plain. The listing says medium caffeine. It does not describe the flavor, so expect an earthy, unsweetened drink.
