SELECTYS® THIOL ROUGE is a Saccharomyces cerevisiae strain belonging to the SOFRALAB GROUP's internal collection® and identified by the Innovation, Research & Development department through a programme enabling a strain to be selected on the basis of its genetic profile and aromatic impact. SELECTYS® THIOL ROUGE was chosen because it: • carries the nucleotide sequence (+ 38 bases) in the IRC7 gene coding for the synthesis of the protein linked to the revelation of thiols (β-lyase activity), • produces aromatic compounds which act as aroma vectors that amplify the fruity, fresh aromatic profile of red wines. SELECTYS® THIOL ROUGE favours the expression of fresh fruitiness with notes of black berries.
