Yes, that is what I tasted .. a weird undertaste. Mine was the organic coffee bean flavoring, not the extract.
See, I have always said that too but, I was the only one that tasted it up until now. Hard to describe but maybe almost a chemical like taste? IDK but it is not good and does get stronger as it steeps to me. It is almost nauseating (so, sorry Bov!) I like what I have tried of the extracts so far much better. The alcohol is there but that funky undertaste is not lol
