===Souring in the Boil Kettle===
Souring Also known as ''kettle souring'', souring in the boil kettle is a simple process that is often used if the brewer wants to subsequently heat pasteurize the wort. Pasteurizing the wort has the advantage of allowing the brewer to rack the pasteurized wort into a fermenter and pitch brewer's yeast without fear of an ongoing Lactobacillus infection in their post-boil equipment.
The brewing process is the same for any all grain batch up until the first wort and sparge runnings are collected into the boil kettle. The temperatures that a typical mash out/sparge reach should be enough to pasteurize the wort <ref name="pasteurization">[http://science.howstuffworks.com/life/cellular-microscopic/pasteurization4.htm Heat pasteurization]</ref>. Once all of the wort is collected in the boil kettle, the wort is chilled to around 80-120°F (37-48°C), depending on the [[Lactobacillus]] culture that is being used. Once chilled to the temperature that is appropriate, the wort in the kettle is inoculated with a culture of Lactobacillus.
