Scientific Publications

A listing of peer reviewed scientific publications and non-peer reviewed scientific studies that focus on subject material that is relevant to sour brewing. Some good journals to keep an eye on for new publications about sour and funky beers include Cerevisia, The Journal of the Institute of Brewing, and The International Journal of Food Microbiology.

Brettanomyces

Much of the scientific research done to date on Brettanomyces approaches the yeast from the view point of wine production and treating the yeast as a spoilage organism. These papers can still be useful to brewers interested in using Brett while recognizing the possible preconceptions, motivations, and biases that this viewpoint might contribute. Other groups, notably those led by a couple of Belgian researchers as well as Chad Yakobson's masters work, have studied Brett from the viewpoint of a desired component in certain beer fermentations.
