Fast restart of stuck fermentations.

Purpose

Fermivin® CHAMPION BOOSTER is a fructophilic strain with very high alcohol tolerance. Thanks to a new specific production process, the fermentation kinetics of strain 67J are boosted.

Fermivin CHAMPION BOOSTER therefore restarts sluggish or stuck fermentations faster.

It is even more effective if added after detoxification with Extraferm® D’tox in an already stuck fermentation, as these yeast hulls very effectively remove the toxic compounds that inhibit alcoholic fermentation. See also the article on restarting a stuck fermentation.

Alcohol tolerance 18 % vol.
Temperature range 15–30 °C

Science and technology

Fermivin CHAMPION BOOSTER is a fructophilic strain thanks to a unique hexose transporter (the HXT3 version of strain 67J). Because of its high affinity for fructose, the strain can ferment fructose together with glucose and is therefore very well suited to restarting stuck fermentations.

The specific production process improves implantation and fermentation performance, speeding up the restart even further.

Сравнение на способността за рестарт на два щама. Опити на INRAe във вино от Chardonnay с 12,85 % vol. алкохол и 21,1 g/L остатъчна захар – pH 3,50; ТА 3,90 g/L H2SO4; ЛК 0,46 g/L H2SO4; свободен SO2 14 mg/L; общ SO2 92 mg/L (след добавка на 4 g/hL).
Comparison of the restart capacity of two strains. INRAe trials in a Chardonnay wine with 12.85% vol. alcohol and 21.1 g/L residual sugar – pH 3.50; TA 3.90 g/L H2SO4; VA 0.46 g/L H2SO4; free SO2 14 mg/L; total SO2 92 mg/L (after adding 4 g/hL).

Tasting notes

Completing alcoholic fermentation with Fermivin CHAMPION BOOSTER protects the wine from undesirable compounds (off-odours) that appear in slow or stuck fermentations.

Metabolic characteristics

Production of SO2 < 10 mg/L
Glycerol production 5–7 g/L

Killer factor neutral

Fermivin CHAMPION BOOSTER contains more than 10 billion active dry yeast cells per gram.

Origin

Species: Saccharomyces cerevisiae var. bayanus. Strain 67J was selected and validated by INRAe (National Research Institute for Agriculture, Food and Environment) in the Corbières area (Languedoc, France) in 1967. It was first marketed by Gist-Brocades in 1978. The specific production for Fermivin CHAMPION BOOSTER was introduced in 2017.
