Large breweries usually apply more cost-effective processes to produce beer, such as the use of cheaper raw materials including supplementary grains. Craft breweries, on the other hand, use only barley malt as a raw material in beer production, the use of which may be related to the existence of different or richer phenolic compounds in craft beers (Cheiran, Manfroi, Kahmann, & Frazzon, 2019). During storage, phenolic compounds in beer cause turbidity by reacting with proteins. Large breweries usually utilize clarification process by removing these phenolic compounds. After the clarification, the beer has to be stabilized by exogenous antioxidants to enhance the flavor. While craft beer is not filtered and do not use additives, hence has higher contents of phenolic compounds than that in final commercial beer (Marques, Quelhas, Visentainer, & Monteiro, 2017).<ref name=yangao/> | |||
