The H 2 S starts converting to mercaptans almost immediately, and fermentations without adequate nitrogen will leave you with reduced sulfur compounds and off-smells in the finished wine. 4.

Indeed, Pambianchi goes so far as to say, “In general, it is good practice to add yeast nutrients when making wine from grapes or fresh juice to ensure a problem-free fermentation.” The distinction regarding grapes or fresh juice is important to note. The reason why grapes are most commonly used in wine making is due to their large amount of naturally occurring yeast, which covers the surface of grapes.
