Tea
Even more water-sensitive than coffee
Why tea is so sensitive
Tea's flavor compounds - especially in green, white, and delicate oolong teas - are often more subtle than coffee's, so water chemistry issues that a bold espresso might mask become much more noticeable.
| Tea type | Ideal water |
|---|---|
| Green / white | Softer, lower-mineral water |
| Black | Moderate mineral content, fuller body |
| Any type | Chlorine-free - always the first improvement |
Key takeaway
Hard water can cause a filmy, iridescent layer on brewed tea - a reaction between tea compounds and excess calcium/magnesium. Cosmetic, but a clear signal.
Filtration solves chemistry, not technique
Filtered water improves the baseline quality of what you're extracting into - it doesn't replace correct brewing temperature and steep time for the specific tea type.
Frequently asked questions
- Does RO water work for tea?
- Similar to coffee, straight RO can taste hollow - tea relies on some mineral content, though less than coffee.
- Why does my tea look filmy sometimes?
- Most commonly a hard water reaction - not a safety concern, but worth addressing.
