You also do not want to add excessive nutrients at the beginning of fermentation .

In addition, residual nutrients in the wine may contribute to microbial spoilage during aging.
Can you make wine without yeast nutrient?

Do I need yeast nutrient?
Yeast nutrition is an essential factor in the overall health and success of fermentation. Managing nutrient requirements not only allows for regular and complete fermentations but enhances sensory quality. Nitrogen , the most important yeast nutrient, is a key factor that has a significant impact on wine fermentation.
Are raisins a yeast nutrient?

The amount of nitrogen added by a handful or two of raisins is miniscule, unfortunately this myth persists. ...
