Boone counts every distinct named ingredient on the Starbucks published component lists, including sub-ingredients, and removes duplicates, so milk appearing in three components counts once. Additive class names are dropped and the named substance kept, so "stabiliser: guar gum" counts guar gum once. Raw covers whole foods and basic kitchen staples such as water, coffee, milk, sugar and salt. Manufactured covers substances that only exist as an output of industrial processing. Figures are for the standard build; syrups, cold foams, whipped cream and drizzles added to order are not included. Retrieved 28 August 2026.
