Contact LeafSteep

LeafSteep is a small, independent, ad-supported site — there is no support desk standing by, but a real person reads everything that comes in to support@dayoba.com.

A few things this address is genuinely useful for: a calculator that gave you a result you think is wrong (say which tool — the steep time & temperature calculator, caffeine calculator, tea-to-water ratio calculator, tasting wheel, gongfu brew timer, or water hardness calculator— and the values you entered); a tool you wish existed on the site; an error or unclear step in the blog, learn section, or the museum; or a bug in how a page looks or behaves on your device.

There’s no fixed response time to promise, and no ticket number or live chat — email is read and handled as it comes in. LeafSteep provides general-purpose calculators and reference content, not personalized brewing consultations, and it isn’t affiliated with any tea estate, brand, or retailer.

Before writing in about a tool result, it’s worth double-checking the values you entered — the wrong unit (grams versus teaspoons, ppm versus grains per gallon), a mismatched cup size, or a mistyped number is the most common source of a surprising answer. If it still looks off after that, that’s exactly the kind of message worth sending.
