Our verdict

A case of organic, canned yerba mate in a berry lemonade flavor with a stated caffeine amount. The title says low sugar but the listing gives no sugar figure, so check the can if that number matters.

Overview

Guayaki makes this ready-to-drink yerba mate with a berry lemonade flavor and sells it as a case of canned drinks. The listing calls it certified organic, fair trade and a certified B Corporation product, and files it as an energy drink alternative.

Yerba mate gives a caffeine lift with a flavored, juice-like taste, and the organic and fair trade tags will matter to some shoppers. The limitation is missing sugar and calorie detail, since low sugar is claimed in the title without a number behind it.

Who it's for

A workday fridge or gym bag where a flavored, caffeinated mate stands in for soda or standard energy drinks. Those sensitive to caffeine, or who want an unsweetened tea, should look at another style.

Pros and cons

Pros
  • Certified organic and fair trade
  • Stated caffeine amount
  • Vegan, gluten free and kosher
  • Hydration and energy uses listed
Cons
  • Sugar and calories not listed
  • Caffeinated, adult age range
  • Flavored, not plain yerba mate

Performance notes

The caffeine comes from the yerba mate leaf, so the lift is tied to that natural source. Berry lemonade flavoring masks the herbal edge and makes it taste closer to a fruit drink than a tea. How quickly it works depends on the person, since the listing only states the caffeine amount.
