Why, and what each one means
We weight independent testing (30%) and sourcing (25%) most. Steeped tea is usually low in lead: Consumer Reports found it concerning in only two of 30 teas after brewing (2024 tests (opens in a new tab)). Matcha is different because you drink the leaf: every one Lead Safe Mama tested (opens in a new tab) had lead, 23 to 153 ppb, so we reward makers who publish numbers. Loose leaf beats bags (guide); fluoride rises with leaf age (study (opens in a new tab)).
- Leaves & farming 25%
- Certified organic with a named origin and harvest; for teaware, the maker and where it is made.
- Independent testing 30%
- Pesticide, lead and fluoride results for the tea, published; for teaware, lead and cadmium tests of glazes. Independent tests count most.
- What touches the tea 15%
- Loose leaf or paper bags without plastic mesh; glass, clay, porcelain, stainless steel or bamboo in the pot and tools.
- Trust 10%
- Highest when the maker names everything, answers questions, and has no recalls, warning letters, Prop 65 notices or lawsuits over safety or labeling. Points come off for unresolved problems and for paid promoters it does not disclose.
- Value 20%
- Price per cup or per gram against the others here that pass.
Each product scores every one from 1 to 5, and its rating is the weighted average. We list only products rated 3 or above that break none of our rules.
We avoid
- Plastic mesh tea bags and plastic infusers steeped in boiling water.
- Matcha with no origin or test results, especially very cheap “culinary” tins.
- Glazed cups and pots, often imported, that make no lead statement.
- “Toxin-free”, “purest” or “heavy-metal free” claims with no numbers behind them.
