Fusel alcohols can be formed from intermediates in branched-chain amino acid biosynthetic pathways. These authors also suggested that nitrogen starvation could lead to a depletion of methionine and cysteine in the yeast cell, resulting in derepression of genes in the sulfate reductase pathway and thereby increasing the flux of sulfur. The aromatic complexity of wines varies according to the primary or varietal aromas associated with the grape from which they were produced, the secondary aromas formed by yeast during fermentation, and the tertiary aromas that develop during aging. Tetrahydrofolate one-carbon metabolism plays a role in methyl group biogenesis, vitamin biosynthesis and the anabolism of some amino acids [ 4251 ]. However, the involvement of urea in ethyl carbamate formation in wine has led to a ban on its use [ 17 ].
