Where are absorbed toxins stored in the grape plant? Leaves? Roots?
Fruit? Inner city soil is typically high in lead and various other
pollutants.

I have an urban organic garden on my property, and what edible plants I
grow (a fair number) are grown entirely in soil I had trucked in and
build beds with. Just being near city streets will have deposited much
lead from car exhaust, and who knows what else was dumped in the yard
before I bought the house?

Even if I did drink wine, I wouldn't drink that wine until I knew about
more about this question.

Residues from herbicides, pesticides, and air pollution would settle on
the outside of a plant. Absorption from the soil is unlikely in that
roots facilitate the passage of certain nutrients which are required by
the vine, leaving undesired compounds and minerals to decay or wash away
with a rain.

That's certainly not true of carrots. They'll collect lead from the
soil. They're one of the worst vegetables to plant in polluted soil.

If wine is made, the yeast will absorb any heavy metals that it may
contain. The clear wine is decanted (racked) away from the sediment
(including the yeast), which results in a wine, free from toxic levels
of heavy metals and/or pesticides.

Ah, OK. Thanks.
