What negative attributes can malt contribute to beer?
Negative characters contributed to beer by malt are summarized in Table 2. In addition to these effects on beer, malt components can also influence the brewing process itself. For example, excessive levels of beta-glucan can give rise to poor wort filtration and beer filtration performance. Malt components can bring about premature flocculation of bottom-fermenting yeast during fermentation, or changes in the skimming behaviour of ale yeast strains. And malt may be implicated in fobbing during fermentation. Table 2. Negative characters contributed to beer by malt.
