Homebrewing API
Homebrewing maths as an API, computed locally and deterministically. The abv endpoint computes the alcohol by volume from the original and final gravity — both the simple (OG − FG)·131.25 estimate and a more accurate high-gravity formula — along with the apparent and real attenuation and the calories per 12 oz serving. The gravity endpoint converts freely between specific gravity, degrees Plato and Brix (the three ways brewers and winemakers measure dissolved sugar) and reports the gravity points. The ibu endpoint computes hop bitterness in International Bitterness Units by the Tinseth formula from the hop alpha-acid percentage, the weight, the boil time, the batch volume and the wort gravity, returning the utilization and the alpha-acid concentration too. Gravities are specific gravity such as 1.050, hop weight in grams, boil time in minutes and volume in litres. Everything is computed locally and deterministically, so it is instant and private. Ideal for homebrew, craft-beer, cidery and winemaking app developers, recipe and batch tools, and brewing education. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. This is brewing maths; for a brewery directory use a beer API and for coffee brew ratios a coffee API.
