Lallemand Wildbrew™ Helveticus Pitch 10g

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.
