Life Cycle Traceability Demonstration – Beer Brewing System
The Beer Brewing Process
Depending on the beer type, there may be three or more temperature steps during the mashing process that will influence enzyme extraction, sugar extraction, and sugar conversion.
The times and temperatures affect the sweetness, strength, and “body” of the beer. There are many other variables at the brewer’s disposal such the selection and quantities of malted grain, hops, and other additives, but these static variables are much easier to control.
The brewer may input a brewing profile that specifies a number of steps. The brew profile consists of a series of steps, each with a specific duration and temperature.
