Oolongnotebook is an independent, practical reference for people who want to brew and describe tea more consistently. Presented as a quiet, offline notebook, it brings together steeping tables, a brewing timer, tasting vocabulary, and concise guides to water, brewing methods, and common faults. Its tables cover white, Chinese and Japanese green, rolled and roasted oolong, black tea, raw and ripe pu-erh, and herbal infusions.

For each, they offer starting-point guidance on water temperature, leaf quantity, steeping time, and repeat infusions, with separate figures for Western and gongfu brewing. A temperature and timer tool adjusts recommendations by tea type, method, and steep number, and includes controls to start, reset, or adjust the countdown. The tasting glossary explains terms for texture, aroma, flavour, finish, and the leaf, helping readers record cups with consistent language.

Short articles offer practical advice on estimating water temperature, choosing water, understanding tea-to-water ratios, and improving an unsatisfactory brew
