Below is a brewing process that the group we tried to summarize you understand The process of brewing beer is typically divided into the following stages Whirlpooling Whirlpooling Worting and hops Worting and hops adding adding Lautering Lautering Malting Malting Fermentating Fermentating Maturing Maturing Filtering Filtering Packaging artwork Barley grains are very rich in nutrients They are classified in a certain size to ensure the spent grains having the equal dimension The grains with the width of 2.5mm and over are selected First, the nutritional components such as starch and proteins are resolved Barley which is in the process of germination is also known as “Green Malt.” The Green Malt contains many enzymes which are the extremely important factors in the next stage Then the Green Malt is dried with the hot air flow at about 80oC, this action helps to control the proliferation of bacteria and to preserve Malt in good condition for a long time Prior to boiling, the malt grains are milled into particles, this process improves the efficiency of converting the starch in the grains into sugars (saccharification) Step Step To resolve and break the crystalised structure of starch, malt is put into the boiling tank and brought into boiling water to convert into a melted form This stage is called “gelatinization” www.themegallery.com Step Step Step Step At the end of saccharification, filtering is performed to remove solids In addition, malt grains must be classified to ensure the homogeneity of size Company Logo Lautering This is where the filter in the filtration process brewery Worting and hops adding The boiling of malt liquid and hops extract components of hops that contribute bitterness and aroma to the beer; it also prevents microorganisms and enhances the retention of beer froth The malt liquid reaches the proper concentration The proteins are precipitated in the beer liquid The residual enzymes in the malt liquid are deactivated, and the malt liquid is thoroughly sterilized Hops bitterness to help create beers Whirlpooling Whirlpooling Filtered solids in Filtered solids in the fluid malt the fluid malt Malt is poured into this tank, as it spins the centrifugal force collects the denser solids into the center of the whirlpool Malt is cooled down to the fermentation temperature and then is provided with the necessary enzymes for the growth of yeast Yeast is put into the solution once malt is cooled to the fermentation temperature (8-10oC for bottomfermenting and 15-20oC for topfermenting) and enzyme is added Yeast then absorbs sugar and makes sugar fermented Under the impact of enzyme fermentation, sugar transforms into alcohol (methyl alcohol) and CO2 The young beer is formed a week later www.themegallery.com Company Logo Maturing Beer is transferred to the storage tank, where it is fermented again Company Logo Young beer will be transferred to the maturing tank The fermentation stage won’t be completed until approximately 85% amount of sugar has fermented Frozen under 0oC, it will be matured for several weeks Young beer must have fermentable extracts and remain a proper amount of yeast to ensure the next fermenting stage works efficiently Filtering Yeast and other dregs in the maturing process will be filtered Packaging Empty bottles recovered Cleaning and disinfection Filling and bottling In fact, in the brewing process manufactures are adding some additives such as cooking process also experiencing some small stage So that you understand the group we’ve picked out the most important to introduce -> thank you and you’re listening Company Logo www.themegallery.com LOGO The end Thank you!
