Stimula Syrah
Stimula Syrah is 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. As the uptake of thiol precursors occurs in the very early stages of fermentation, the addition of Stimula Syrah at the very beginning of alcoholic fermentation will enhance yeast metabolism, avoiding any catabolic repression and increasing the transporters efficiency. This is essential for thiol precursors and their bioconversion to volatile thiols, particularly 3MH.
In addition, the high level of vitamins helps to avoid H2S production and limits the excessive reductive character that masks positive aromas.
- Stimula Syrah increases the release of varietal aromas.
- Helps to avoid sulfur off-flavours.
- Increases yeast ethanol resistance.
