General Disclaimer

The information and tools provided by LeafSteep (“https://www.dayoba.com”) are for general educational and brewing-reference purposes only. Everything here is offered in good faith, but we make no representation or warranty of any kind, express or implied, as to the accuracy, adequacy, validity, reliability, or completeness of any information or result on the site.

A Brewing Guide, Not Certified Advice

LeafSteep’s calculators — the steep time & temperature calculator, the caffeine calculator, the tea-to-water ratio calculator, the tasting wheel, the gongfu brew timer, and the water hardness calculator — are designed to help you brew tea more consistently and understand what you’re tasting. They are not professional, nutritional, or medical advice, and taste is inherently subjective. Adjust every recommendation to your own leaf, water, and preference.

Caffeine Estimates Are Not Medical Guidance

The Tea Caffeine Calculator produces a rough estimate built from commonly cited averages, not a laboratory measurement of any specific tea. Actual caffeine content varies substantially by cultivar, leaf grade, growing conditions, processing, and how the tea is brewed. This tool is for general interest only. If caffeine intake matters to you for a health reason, consult a qualified medical professional and rely on a lab-tested source rather than this or any online estimate.

Results Are Rounded Estimates

The tools apply standard formulas and commonly cited brewing conventions, and round their output for readability. That rounding, together with the assumptions of a deliberately simple model, means a displayed value may differ from what you experience with a particular tea, water, or equipment.

Water Hardness Is About Flavor, Not Safety

The Water Hardness Calculator classifies mineral content for its effect on tea flavor. It is not a drinking-water safety assessment. For any question about the safety of your water supply, contact your local water utility or a qualified water-testing service.
