Coffee is mostly bitter in taste, Orange juice or Ananas juice is fairly sweet and acidic in taste in comparison.

So you are supposing the taste has something to do with it? because on the ph scale oj and coffee are pretty close. Sounds extremely subjective.

Likely yes.

I do find that a glass of oj gets me "moving" rather quickly in the morning
