I went with the white grape juice almost exclusively. To my complete surprise, when I needed to "use the facility" the by-product reeked of white grape juice. I'm 66 years old and I never had an odor reflect so precisely what I had taken in. That really astonished me. Yes, different foods give you different results, but none that had so much the same odor/fragrance as what was taken in. I don't know if anyone else ever had the experience.

That experience made me remember reading a biography of Benjamin Franklin. He had attempted to find a way to influence the odor of flatulence. He was never successful. I remember he had tried intaking perfumes, rose petals, etc. He should have tried white grape juice.
