• 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.
