Not to nit-pick (or even grape-pick), but we still don't get an "exact
percentage" without defining percent determined by what?

So, we've got a field with zinfandel, carignane and petite syrah
vines. Do we get our percentage by weight of grapes picked? By number
of discrete grapes (I know that's absurd, but bear with me...)? By
volume of pressing liquid? By volume of the picked grapes--77 barrels
of picked zin, 16 of picked carignane...? By ratio of vines picked?

Are all varietals even picked at the same time, or might one varietal
be harvested two weeks later?

I'm not seeking a UC/Davis education, but simply holding feet to the
fire regarding what should be a fairly simple question.
