Barley Brewing

Unlock cost savings and sustainability with barley brewing

Using barley over other cereal adjuncts offers significant advantages to the brewer. Because its starch has a similar gelatinisation temperature (53-58˚C) to malted barley (61-65˚C), it can be easily incorporated into conventional malted barley mashing procedures. Its endogenous ß-amylase ensures maltose production during mashing. Likewise, the presence of a husk can aid mash filtration through a traditional lauter tun. However, because of its low endogenous enzyme levels and high levels of unmodified cell wall components, brewing with raw barley can present many processing difficulties to a brewer.

Barley brewing also has a significantly positive environmental advantage over malting, because it is a less energy-intensive process. The potential savings for brewing with barley, and the decision at what level to brew with, depend on several factors, including:

  • Raw material prices

  • Percentage of barley used

  • Quality of barley (and malt)

  • Process design (milling, mashing, brewhouse lautering/filtration system) and final product specifications (e.g. taste panel and consumer acceptance)
