Data corrections

When reporting a correction, include the brand, exact product name, UK or US market, serving size and a link or photo reference to the current label. Include the caffeine, sugar or calorie value you believe needs updating and whether the label states a per-serving or per-100ml amount.

A useful subject line is “Drink correction: [brand] [product] [size] [country]”. If you send a label photo, include the nutrition panel and caffeine statement, and crop out receipts, addresses or other personal information.

Suggest a drink

Send the product name, country, container size and manufacturer page or readable nutrition label. An imported product may differ from the local version, so the market matters. We need supporting nutrition information before a new drink can be treated as verified.

Calculator feedback

For a calculation or display problem, tell us which device and browser you used, which drinks and quantities you selected, and what you expected to happen. Please do not include medical records or other sensitive personal information.
