There are many chemicals used for cleaning / filtering in bier which technically don't/shouldn't end up in the beer and as such do not have to be listed; also the main ingredients are plants and as such they are fed and sprayed with things that are not ingredients. Pesticides and micro plastics are found in most (all?) German beer but are not direct ingredients so they are not listed.
