Amberinfusion is a quiet, practical tea-brewing notebook designed to help tea drinkers prepare and describe a cup with greater consistency. Its reference tables offer starting points for water temperature, leaf quantity, steeping time and re-steeping across white, green, oolong, black and pu-erh teas, as well as herbal infusions. Figures are provided for both Western brewing and gongfu methods, with guidance on adjusting for different leaves.

A built-in temperature and timer tool lets users choose a tea and brewing method, then view suggested settings and time successive steeps. The notebook also presents 19 tasting terms covering texture, aroma, flavour, finish and leaf characteristics, helping readers record and compare their impressions. Three short guides address judging water temperature, understanding Western and gongfu ratios, and correcting brewing faults. Amberinfusion works offline, requires no sign-up and does not save information between visits. Its pages are designed as accessible references for everyday brewing, offering clear guidance while emphasizing that the suggested measurements are starting points rather than strict rules.
