I am not sure you can generalize. In the case of wine, what we make today
bears no resembelence to Chazal's wine. What they called yayin was
- thick enough that in order for it to reach the ground the same time as
  water, the mizbeiach had to have a measurably wider shis for nisuch
  hayayim than nisach hamayim (Sukkah 48a);
- thick or strong enough to require mezigas hakos to the point that what
  one drank was 67% water (Raba would drink 25%; Eruvin 54a); and
- tasted poorly, and was usually spiced and sweetened. (Tehillim 75:9;
  lehavdil, there is also textual evidence of what was done in Judea in
  its day in the Xian bible.)

What we have today is a vastly different product. The differences caused
by centuries of horticulture and in the technology of storing liquids
(to minimize evaporation) is far more clear than most cases of nishtanah
hateva.

Tir'u baTov!

micha at aishdas.org        with the proper intent than to fast on Yom
