Depending on the brewing / extraction method, it's effect might not be noticeable. In a french press, where nothing but coffee and water are involved for a long extraction time, it can be noticeable. Shorter brew times and/or certain filters can potentially reduce or eliminate the bitterness too. It's all rather subjective, personally, even with a pinch of salt, I still find french press coffee to often be unpalatable. YMMV.
