Trang 3In today’s mordern life, beer is not a drink strange to us It is everywhere and everyone can use regardless wealth After you get euphoria felling that they had brought beer when you wonder produced beer like???
Below is a brewing process
that the group we tried to
summarize you understand

the following stages

Trang 6Barley 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 1 Step 2 Step 3
Lautering
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”
In addition, malt grains must be classified to ensure the homogeneity
of size
At the end of saccharification, filtering is
performed to remove solids
Trang 8This is where the filter in the filtration process brewery
Trang 9Worting 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 residual enzymes in the malt liquid
are deactivated, and the malt liquid is
thoroughly sterilized
The proteins are precipitated in the beer
liquid
Hops bitterness to help create beers
Trang 10Whirlpooling 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
bottom-fermenting and 15-20oC for
top-fermenting) 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

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
Beer is transferred to the storage tank, where it
is fermented again
Young beer will
be transferred to the maturing tank
The fermentation stage won’t be completed until approximately 85% amount of sugar has
fermented

Yeast and other dregs in
the maturing process will
be filtered
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

Thank you!
