Field notes
The homepage groups calculators by ferment rather than by formula: pickles and brine, kombucha, sourdough, beer, yogurt and dairy, mead and cider, condiments, and general tools. Individual entries describe concrete jobs, including calculating salt from water or total weight, estimating kimchi time from storage temperature, and plotting kimchi ripening or kombucha carbonation windows on a timeline. It also says formulas are explained and reference numbers sourced; the extracted homepage does not expose calculator input screens.
