Stimula™ is a new range of 100% yeast autolysate products developed to supply the optimal levels of
organic nitrogen sources in order to optimize yeast metabolism and to promote the aromatic profile of
different grape varieties.
Stimula Syrah™ is an organic nutrient particularly rich in different nitrogen sources (peptides and free
amino acids), specific vitamins (pantothenate, thiamine) and minerals to increase the release of varietal
aromas and avoid sulfur off-flavors.
This specific composition results in an increase in the release of varietal aromas (thiols, terpenes and
norisoprenoids). As the uptake of thiol precursors occurs in the very early stages of fermentation, the
addition of Stimula Syrah™ at the very beginning of the alcoholic fermentation (AF) will enhance yeast
metabolism, avoiding any catabolic repression and increasing the transporter’s efficiency. This is essential
for thiol precursors and their bioconversion to volatile thiols, particularly 3-mercaptohexanol (3MH). In
addition, the high level of vitamins (pantothenic acid) helps to avoid H2
S production and limits the excessive
reductive character that masks positive aromas. The optimized content in oligo-element (magnesium) also
increases the yeast ethanol resistance.
