What is Quick/Kettle Souring?
Quick souring is a way to make a sour beer quickly using a pure culture of Lactobacillus.
While this method was originally developed with the kettle in mind, nowadays many brewers use closed fermentors to perform souring. This is why we refer to the process as Quick Souring from this point onward rather than Kettle Souring.
What do I need to make a sour beer?
To quick sour a beer, you’ll need a culture of Lactobacillus (we recommend Lactobacillus Blend 2.0) and one of the following souring vessels:
- A completely airtight brew house (uncommon)
- A brew house fitted with a CO2 purging system
- A fermentor
Overview of Quick Souring Methods
Quick souring can be broken down into 3 steps:
