In Lallemand Standard Wort conditions, WildBrew™ Sour Pitch bacteria exhibits:

  • Fast pH drop that can be completed within 2 days (typically within 24 to 36 hours).
  • High lactic acid versus lower acetic production.
  • Aroma and flavor is citrus and tangy with a hint of fruit.

The optimal temperature range for WildBrew™ Sour Pitch when producing sour beer styles is between 30°C to 40°C (86°F to 104°F)

Fermentation rate, fermentation time and pH drop are dependent on inoculation density, bacteria handling, fermentation temperature and nutritional quality of the wort.

    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.
