SELECTYS® La Raffinée

SELECTYS® LA RAFFINEE is a natural yeast selected by Sofralab for its capacity to elaborate fruity and complex red wines that will be aged or not.

• Elaboration of fruity and complex wines that can be aged or not made from high quality international grape varieties
• Targeted valorisation of red grape varieties rich in methoxypyrazines and unripe grapes

Fermentation characteristics:

• Species: Saccharomyces cerevisiae
• Killer factor: sensitive
• Optimum temperature range of fermentation: 15 to 28°C
• Fermentation kinetics: average
• Alcohol tolerance: up to 16 % Vol.
• Production of volatile acidity: low
• Nitrogen requirements: high
• SO2 production: average

Organoleptic characteristics:
SELECTYS® LA RAFFINEE, thanks to the enzymes it contains, develops fruity and complex aromas through the production of fermentation esters and varietal aromas. In addition, it decreases the vegetal notes (such as green bell pepper) linked to the presence of methoxypyrazines.

Thus, SELECTYS® LA RAFFINEE is particularly suitable for grape varieties such as Merlot, Cabernet etc… or unripe grapes.
