Sihaferm Finesse Red
SIHAFERM Finesse Red yeast is a newly selected pure yeast of the new generation, based on color stability and protection at high fermentation temperatures. It is recommended for the fermentation of Pinot Noir.
Technical Specifications
SIHAFERM Finesse Red Yeast is a selected yeast strain produced using classical selection techniques. It features low ß-glucosidase activity and is POF(-), meaning there is no production of negative, volatile phenols. These selection criteria support the optimal protection and stabilization of color.
SIHAFERM Finesse Red yeast has a strong fermentation activity and does not produce killer toxins.
The yeast can tolerate SO2 quantities up to 18 gr/100 fl oz (40 mg/l).
SIHAFERM Finesse Red yeast can produce up to 15.5% alcohol by volume. The practical alcohol yield is approximately 47% of the sugar content. For each lb (kg) of sugar fermented, approximately 247 kJ (59 kcal) of heat is released.
Features and Benefits
The specific advantages of SIHAFERM Finesse Red yeast:
- Pinot Noir Yeast
- High color stabilization ability and color protection especially at fermentation temperature 77 – 86 °F (25 – 30 °C)
- Excellent color extraction up to 25%
- Increase of polymerization of color compounds due to the better extraction of colorless phenols
- Low foaming ability at fermentation temperature ~ 64 °F (18 °C)
Product Applications
In general, musts and mashes should be inoculated with SIHAFERM Finesse Red yeast as early as possible. Longer maceration times promote uncontrolled propagation of wild yeast and undesired bacteria.
The fermentation range is between 59 and 86°F (15–30°C). The optimum fermentation temperature is between 64 and 82°F (18–28°C).
SIHAFERM Finesse Red yeast is best stirred into 10 times the amount of a fifty-fifty must-water mixture at 95–98.6°F (35–37°C), stirred again after 2–3 hours, and then added to the must. Please note that the pure yeast SIHAFERM Finesse Red forms only a slight head of foam or none at all.
