SAUVY™
(Saccharomyces cerevisiae)
For optimal expression of varietal thiol aromas.
SAUVY™ has been selected through an innovative microbiological approach due to its unique metabolism and enzymatic activities resulting in the exceptional potential to uptake and release volatile thiols, especially 4MMP (also known as 4MSP). Combining those distinctive properties and abilities to express other aromas, SAUVY™ is well suited for the production of intense and fresh aromatic whitewines. Wines fermented with SAUVY™ show typical flavor profiles described as boxwood, gooseberry, tomato leaf, passion fruit, citrus and black currant. SAUVY™ also favors refreshing and crisp mouthfeel sensation. Moreover, thanks to its unique enzymatic activity, SAUVY™ can build up a high reservoir of thiols precursors, which are gradually released over time after alcoholic fermentation. Wines obtained with SAUVY™ develop intensity and aromatics even better some weeks or months after alcoholic fermentation.

FAQ
SAUVY™ can be used with any grape variety that has thiol forming potential, to maximise varietal expression.
It can also be applied to more neutral varieties or warm climate juices to support a fresher and more vibrant aromatic profile.
SAUVY™ was selected through an innovative selection approach that enables the full IRC7 gene expression. IRC7 encodes β-lyase activity, the key enzyme responsible for releasing varietal thiols during alcoholic fermentation.
Choosing SAUVY™ maximises thiol release and enhances varietal typicity.
• Yeast inoculation temperature: >16 °C (18 °C recommended during the first third of alcoholic fermentation)
• Initial SO₂ addition: ≤ 5 g/hL (pay attention to molecular SO₂ at low pH)
To fully maximise your grapes’ aromatic potential, SAUVY™ can be used in combination with synergistic products such as: LalVigne AROMA™, GLUTASTAR™, STIMULA SAUVIGNON BLANC™, and PURE-LEES LONGEVITY™.
