Sour Beer Cultures

This list taken from https://www.themadfermentationist.com/p/dreg-list.html last copied 2/5/2018.


This list is divided into three categories: sour beer with both yeast and bacteria; those that contain Brettanomyces, but not bacteria; and those that contain bacteria, but not Brettanomyces. It is by no means comprehensive, but it should include at least a few bottles that almost everyone can find at a local store that specializes in good beer. There are a number of sour beers out there that are pasteurized or filtered after fermentation is complete, so be careful of those not listed. Examples of beers that do not contain viable dregs include many Belgian Flemish reds (e.g., Rodenbach), sweetened fruit lambics (e.g., Lindemans, Liefmans), and American sour beers from some larger breweries (e.g., New Belgium).

If you are unsure about whether a beer contains viable microbes, contact the brewer to ask. In most cases breweries are consistent, with either all or none of their bottled beers containing viable dregs.
