In 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 process of brewing beer is typically divided into
the following stages
Whirlpooling

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 1
Step 1

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”.

Step 3

At the end of
saccharification,

filtering is
performed to
remove solids

In addition,
malt grains
must be
classified to
ensure the
homogeneity
of size

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

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

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
