Waku Prebiotic Herbal Tea is a caffeine-free, ready-to-drink canned tea made with a brewed herbal blend of lemon verbena, lemon balm, lemon grass, chamomile, white basil, and mint. This Costco Mix & Match variety pack includes 12 cans (12 fl oz each) drawn from five available flavors — Raspberry, Passion Fruit, Peach, Pineapple, and Mango — letting shoppers customize their assortment.

Each flavor is sweetened with stevia leaf extract and monk fruit extract with zero grams of added sugar. The drinks are enriched with chicory root inulin, a plant-based prebiotic fiber that supports gut health. Fruit juice concentrates and natural flavors give each variety its distinct character: Raspberry is fruity and crisp, Passion Fruit is sweet with a slight tartness, Peach is lush and mellow, Pineapple is tropical and tart, and Mango brings a bold tropical sweetness.
