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.
- Ideal for making red wines with fresh, intense black berry aromas.
- Ensures safe fermentation with regular kinetics.
- Suitable for fermenting all varieties with ‘thiol’ potential.
- Fermentation kinetics : Fast
- Recommended FA temperature for thiols : 22-25°C
- Resistance to ethanol : >14.5% vol. <17% vol.
- Production of glycerol : Medium to high
- Production of SO2 : Low to medium
- Production of volatile acidity : Low to medium
- Production of H2S : Low
- Nitrogen requirements : Low to medium
The nutritional requirements of SELECTYS® THIOL ROUGE are low to medium depending on the matrix. However, adequate amino acid nutrition at the start of fermentation is recommended, in order to enhance the desired aromatic profile.
