Vason Premium Fructo 500 gram
An excellent choice for a second yeast in problematic fermentations, retaining the aromatics from the primary yeast while taking the wine to dryness.
SKU: WZZZ1370
This special strain is best used as a restart for sluggish or stuck fermentations. It metabolizes fructose (often found in very high concentrations in a stuck fermentation), thus making it an effective yeast for re- inoculation. It is an excellent choice for a second yeast in problematic fermentations, retaining the aromatics from the primary yeast while taking the wine to dryness. It is not recommended as the primary yeast for must fermentation. Recommended dose: 20-30 g/hL for high alc sequential ferment, or 50-100 g/hL for stuck fermentations. Optimal temperature: 18-30°C (64.4-86°F).
Dose:
- High Alc Sequential Ferment = 20-30 g/hL
- Stuck fermentations = 50-100 g/hL
