WildBrew™ Helveticus Pitch

WildBrew™ Helveticus Pitch is a ready-to-use dried bacteria, a strain of Lactobacillus helveticus specifically selected for its ability to produce a wide range of sour beer styles. In comparison to WildBrew™ Sour Pitch, the new bacteria produces a more intense citrusy flavor at higher temperatures. Additionally, WildBrew™ Helveticus Pitch will deliver unmatched consistency, effortless application, fully assured performance and unparalleled purity for brewing the sour beer style of your choice.

WildBrew™ Helveticus Pitch is recommended at a dosage of 10g/hl to pour directly into the unhoped wort.

WildBrew™ Helveticus Pitch is part of a wider set of solutions for sour beer making, which also includes the newly launched bioengineered Saccharomyces cerevisiae yeast Mascoma Sourvisiae® that can produce lactic acid and ethanol simultaneously.

Classified as Lactobacillus helveticus, a facultative hetero-fermentative strain.

  • Viable bacteria > 1010 CFU/g
  • Dry matter > 92%
  • Coliform < 102 CFU/g
  • Acetic bacteria < 104 CFU/g
  • Moulds < 103 CFU/g
  • Yeast  < 103  CFU/g

In line with Lallemand’s strict quality control and assurance procedures, every single batch of WildBrew™ Helveticus Pitch is released to the market only after passing a rigorous series of tests, guaranteeing the highest standards of purity, quality and performance.

In Lallemand’s Standard Wort conditions, WildBrew™ Helveticus 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™ Helveticus Pitch when producing sour beer styles is between 38°C to 45°C (100°F to 113°F).

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