I read that grape juice has all the nutrients yeast needs.


The perfect grape will have the perfect nutrients for the perfect
yeast. Unfortunately little in the world is perfect and nutrient
hungry yeast stains will produce unintended by products if they are
deprived of specific nutrients. Among these is certainly Nitrogen,
which can be suplimented with DAP or with the amino acid content of
inactivated yeast hulls (ghosts). The best solution would be a mix
of
both, because it both will provide nutrient and the yeast hulls
will
also absorb toxins and pull them to the bottom of the fermenter.
In the future it is prudent to add at 1/3rd sugar depletion a
"complete" nutrient (Fermaid K, Super food) that contains DAP as
well
as essential vitamins like Pentothenic acid and Thiamine which are
proven to avoid H2S production. These nutrients also reduce the
risk
of stuck ferments.
