What those ingredients are, by type

Boone counts every distinct named ingredient on Starbucks’ published component lists, including sub-ingredients, and removes duplicates, so sugar appearing in three syrups counts once. Ice and water added at the counter are not counted. Raw covers whole foods and basic kitchen staples such as milk, sugar, salt and oil. Manufactured covers substances that only exist as an output of industrial processing. Every figure here is a minimum.
