As one of the oldest alcoholic beverages, beer is known as "liquid bread". It is mainly made of barley malt and water with hops added and fermented by yeast, among which brewer's yeast plays an important role. It is the power source of the whole fermentation process. How much do you know about brewer's yeast? Today, beer equipment manufacturers to take you to understand.

Historically, the style of beer that can be brewed in a region has both benefited from and been limited by local water quality. The water in Ireland, for example, is rich in calcium ions and bicarbonate, balanced by the acidity of roasted barley, which makes for a dry world. The water in the Pilsen region of the Czech Republic is extremely soft and contains almost no mineral salt, giving rise to the Bohemian Style of Pilsen. The water in Bolton Trent is extremely hard and rich in calcium sulfate and bicarbonate, which aggravates the bitter taste of hops and makes the mouth plump and dry, resulting in the British IPA.

Water is not only one of the main raw materials of brewing, but also the most widely used raw materials. the key to the quality of beer lies in the quality of beer. The water used to make beer is called "beer blood". The characteristics of the world's famous beers are determined by the water used to produce them. The water used for beer production is the same as the water needed by human body. It must be qualified and conform to industry standards. If it fails to meet these requirements, the quality of beer production cannot be guaranteed and the physical and chemical standards of beer cannot be met.
