Definition: Beer Spoilers are microorganisms that can change the flavour, aroma, or appearance of beer in a manner deemed undesirable by the brewer (and the consumer!!). Although there is some overlap, brewers seek to divide spoilage organisms into the categories of “beer spoilers” and “wort spoilers,” with the latter largely inhibited by alcohol, pH, and/or the anaerobic environment created by yeast fermentation (Priest 2003).
