Educational information only

All content on TeaSteep — calculators, articles, tables, and examples — is published for general educational purposes. It is not caffeine advice and is not a substitute for a qualified professional. We are not physician if caffeine affects your healths, and no client or advisory relationship is created by your use of this Site.

Caffeine figures are typical ranges — actual content varies by harvest, leaf grade, and steep time (longer and hotter extracts more). Pregnant visitors and those with caffeine sensitivities should count all cups against their own limits.

Temperature guidance optimizes for the standard Western steep; gongfu practice uses hotter water, more leaf, and shorter times. Both are correct — they are different hobbies with the same leaves.

Accuracy of calculations

We implement well-known, publicly documented formulas (see the methodology section on each calculator page and published steeping standards and origin-specific practice as applicable). Even correctly implemented formulas produce estimates that depend on your inputs and assumptions. Real-world outcomes vary. Do not rely on a single web tool for a consequential decision.

Advertising disclosure
