Coffee Brewing Data

Brewing parameters and data graphics from the published iCoffee house recipes: coffee-to-water ratio, water temperature, dose, and brew water for every brewing method we publish, as machine-readable data files and charts in five languages. The methods covered today: espresso, moka pot, V60, AeroPress (standard and inverted), French press, siphon, cold brew, and Japanese iced coffee.

All values are the parameters we actually publish and maintain in our recipes, not aggregated third-party figures. The full write-up with context and sources lives on the iCoffee coffee statistics page: icoffeeapp.com/en/learn/coffee-statistics.

Data files

File	Contents
data/brewing-parameters.csv	One row per house recipe: canonical_id, method_en, ratio, water_parts, water_temp_c, coffee_dose_g, brew_water_ml
data/brewing-parameters.json	Same dataset with export metadata (generated_at, source_hash, recipe_count)
data/method-labels.csv / .json	Localized brewing-method display names (English, Spanish, Brazilian Portuguese, Simplified and Traditional Chinese)

ratio is the coffee-to-water ratio as published (e.g. 1:15); water_parts is its numeric water side for sorting and plotting. water_temp_c is the brew water temperature in °C. Missing values (e.g. no meaningful dose for a method) are empty in CSV and null in JSON.

Brewing parameters at a glance

The full dataset, from the current published recipes:

Method	Ratio	Water temp (°C)	Coffee dose (g)	Brew water (ml)
Espresso	1:2	93	18	36
Cold Brew	1:5	20	200	1000
Moka Pot	1:10	100	18	160
AeroPress (Inverted)	1:11	100	18	200
AeroPress	1:15	85	15	225
French Press	1:15	94	30	450
Siphon	1:15	92	17	255
Japanese Iced Coffee	1:16	96	30	300
V60	1:16	96	18	288

The CSV/JSON files carry the same rows with stable recipe ids and the localized method names.

Charts

Provenance and freshness

The dataset is exported from the same recipe corpus that renders the charts on the live site; SOURCE.md records the corpus hash and export date for the current revision. This repository is refreshed whenever the published recipe data changes (new recipes, adjusted parameters, or new chart types), so the files here always match what the site shows.
