Sesame seeds milk tastes slightly nutty and sometimes, it can have some slightly bitter notes. Sesame milk made from hulled seeds (the ones that have the shell removed) tastes more mild (without bitterness) while having a more intense sesame smell. Black sesame milk taste reminds of black sesame paste (but with a smoother texture). I think sesame milk smells of sesame very clearly, but as I gave my husband some sesame milk for blind tasting, he thought it might be some kind of nut milk, so maybe it doesn’t taste/smell as strong of sesame.
