Awesome work, Dave! I added a Category tag.
[[Category:Techniques]]
== Introduction ==
Sour mashing is a technique for adding acidity to a beer before primary fermentation begins. This is accomplished by the introduction of lactic acid bacteria after the completion of the mashing process. Sour mashing is similar to [[Sour Worting|sour worting]] in that both techniques involve acidification of unfermented wort with lactic acid bacteria before primary fermentation.
