Beer Spoilage Organisms
Microorganisms — Brewing Stages
From a microbiological standpoint, the brewing process can be broken down into various stages from malting followed by those that include wort production, fermentation, and subsequent beer processing. Microorganism contamination can occur during anyone of these stages. A summary of such microorganisms and the stages of the brewing process at which they are found are outlined in Table 19.1 and will be discussed in more detail further below. The spoilage character of a particular organism will depend on the stage at which it is found in the brewing process.
