Unroasted coffee and raw beans are not suitable for drinking.

Last Updated: 2026/04/04, Unroasted raw coffee beans contain emetic ingredients such as propionic acid, butyric acid and pentanoic acid. If you boil raw coffee beans directly, it is easy to turn your stomach and even vomit. Coffee is so magical that after roasting, these ingredients are neutralized, resulting in more charming aroma and richer taste.
