SELECTYS® Thiol

SELECTYS® THIOL is a strain of Saccharomyces cerevisae isolated in Italy and selected by our R&D department using an innovative genetic identification programme. The aim of the programme was to verify that this strain does carry the nucleotide sequence (+ 38 bases) on the IRC7 gene coding for the protein connected to thiol expression (β-lyase activity).
After three years of trials to validate the strain in the wine-growing regions most recognised for their production of wines with thiol character, and thanks to the Oenofrance®’s R&D department, we were able to verify its ability to bring out aromatic notes of:

• 4-Mercapto-4-Methylpentan-2-one (4MMP): boxwood, broom, blackcurrant bud, tomato leaf
• 3-Mercapto-1-Hexanol (3MH): passion fruit, pineapple, grapefruit
• 3-Mercapto-Hexyle acetate (A3MH): exotic fruits, guava, citrus zest

SELECTYS® THIOL brings out and enhances intense, stable aromas over time.

SELECTYS® THIOL guarantees fermentation security and uniform kinetics.
SELECTYS® THIOL is ideal for the production of white and rosé wines with highly intense, elegant thiol aromas, characterised by freshness and taste persistence.
The strain’s characteristics enable it to adapt to the fermentation of all varieties with thiol potential.
