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.
