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
