Raw Material for Beer Manufacturing
摘要
Malt, the principal brewing raw material, contains extractable components and enzymes. Barley is the main raw material used in making beer, second only to water. The process of malting involves cleaning grains, steeping them in water, allowing them to germinate, and kilning them. The morphology of the grain is crucial for malt quality, with characteristics like kernel shape, hectoliter weight, thousand kernel weight, and uniformity and plumpness. Hops, a perennial plant, contribute to beer brewing by providing bittering and aroma components. Around 97% of the world’s hop harvest is used, with various aromas attributed to hops. Dry-hopping, a popular method, has decreased bitterness in recent years. Beer production involves alcoholic fermentation and maturation, involving various scientific disciplines. Different types have unique characteristics, with Saccharomyces yeasts playing a crucial role.
