Wild Yeast < 1 per 106 yeast cells
Bacteria < 1 per 106 yeast cells
Finished product is released to the market only after passing a rigorous series of tests
*According to the ASBC and EBC methods of analysis
In Lallemand’s Standard Conditions Wort at 20°C (68°F) Belle Saison yeast exhibits:
- Vigorous fermentation that can be completed in 4 days
- High Attenuation and Low Flocculation
- Aroma and flavor is traditional of Saisons with citrus and pepper notes.
- The optimal temperature range for Belle Saison yeast when producing traditional styles is 15°C(59°F) to 35°C(95°F)
Saccharomyces cerevisiae var. diastaticus strains are capable of utilizing some types of dextrins. Extra care should be taken to ensure proper cleaning procedures are in place to avoid any cross-contamination with other brews.
Fermentation rate, fermentation time and degree of attenuation are dependent on inoculation density, yeast handling, fermentation temperature and nutritional quality of the wort.
