Lactobacillus
A microorganism/ bacteria. Lactobacillus is most often considered to be a beer spoiler because it can convert unfermented sugars found in beer into lactic acid. Some brewers introduce Lactobacillus intentionally into finished beer in order to add desirable acidic sourness to the flavour profile of certain brands.
