About Beer Fermentation

Malted barley is the source of the fermentable sugars in beer - and the resulting alcohol in beer is produced by yeast fermentation.

Most yeast fermentation is done with a Saccharomyces strain, which tends to be the quickest and most reliable way to create beer.

Some brewers, thought, are opting for Brettanomyces strains, which take much longer to convert sugars into alcohol, but some say produce a more unique flavor.

Generally, bacteria is seen as a contaminant in beer production, but in certain cases (and especially in the production of sour beers), flavor-enhancing bacteria are added to give these beers their unique taste.

Here is a look at the two most common genus of bacteria used:

  • Lactobacillus converts sugars into lactic acid rather than into alcohol, which lowers the brewing beer’s pH, giving it a sour taste. Popular styles using Lactobacillus include goses and weisses. 

  • Just like the LactobacillusPediococcus converts sugars into lactic acid, also giving the beer a sour taste. However, many beer brewers and drinkers find the Pediococcus strains' flavor-producing profile to be much stronger than the Lactobacillus's. In addition, Pediococcus is more often paired with the Brettanomyces in the brewing process than is Lactobacillus because of the complexity of a longer fermentation time and more unique flavors produced using the Pediococcus. Popular styles using Pediococcus include lambics and certain reds.
