Suggested Varieties: Sauvignon Blanc, Viognier, Riesling, Chardonnay, Rose, Chenin Blanc
Information on Strain:
- Product of the yeast hybridization program of the Institute for Wine Biotechnology at the University of Stellenbosch in South Africa.
- Aromatic as well as cold tolerant (10-15°C/50-59°F), VIN 13 also has high alcohol tolerance (16.5% v/v) and low nitrogen requirements (qualities obtained by hybridizing S. bayanusand S. cerevisiae strains). Good choice for restarting stuck white fermentations, especially when fructose levels remain high.
- VIN 13 is a very good thiol releaser (guava, passion fruit and grapefruit) and outstanding ester producer. On tank-fermented Chardonnay it promotes pineapple and banana flavors, while on Riesling, Gewürztraminer and Viognier it accentuates floral notes.
- The combination of fermentation kinetics and sensory contributions make this strain very suitable for cold-fermented aromatic whites that are fermented to dryness. Do not over inoculate.
