Editor & Lead Reviewer

Justin Park is the editor and lead reviewer at Yerba Mate Reviews. He covers mate across its formats: traditional loose leaf, tea bags, and canned RTDs. He reads every brand on stems, smoke, and strength, checks stated origin, cut, and drying style against the label and the producer's documentation, reads the long-run drinker consensus, and ranks on one scale with zero hype. He does not claim tasting rounds he did not brew. Every review on the site is edited to his standard and every price verified live before a guide is published. Questions, corrections, or a mate you would like reviewed? Reach the desk at hello@yerbamatereviews.com.
