In some cases, animal products may be used in the processing of coffee (e.g., certain fining agents in
sports games decaffeination). Vegetarian coffee would avoid these. Some non-vegetarian coffees might use animal-derived agents during processing, such as isinglass (from fish) or casein (from milk), which would be avoided in vegetarian coffee. If any flavorings or additives are used, vegetarian coffee would ensure they are free from animal products, unlike some non-vegetarian options.
