Hi I'm Sampath Rathnayake
Once again joining with Bar Hopes,
Today let's talk  about
3rd step of Alcohol Production,  Alcohol Fermentation
From this session i would like to explain
process of an alcohol fermentation,
what producers expect
and  fundamental elements for the fermentation process
also let's briefly talk  about, what does alcohol fermentation mean  in General
From a fermentation process, producers are expecting two equally important outcomes
1 . Alcohol
2. Flavours  for the final spirits
Let's talk about later on with little bit more details
Now I'll brief you about fundamental elements for Alcohol Production
There are two main required Elements
1.Sugar solution
2. Yeast
In the second step of spirits production,
i have briefly explained about sugar Solution how does the process happen
trough Processing the raw Materials
So You Have seen how the process is changed country to country
That Accordign to the selected  Raw Materials
what ever  Process and the Raw Materials been used but final expectation of the producer's
to make a sugar Solution for alcohol fermentation.
Not Only that specially  i have to add something to the topic
when we talk about single malt Whisky prodcution
There are couple of additional steps in raw materiel process
, ill talk about single malt whisky in a difefernt episode near future
then will explain the difference between regular Raw material process for the whisky
and the Single malt
So now let's have a look WHAT'S A FERMENTATION?
the sugar solution made  of carbohydrates from the raw materials selected by the  producers
the name of the Sugar solution &  the way it calls  can be changed country to country
In Scotland it calls  WORT or sweet water
as a first step , Producers are adding yeast into WORT or sweet water (EX-10000L WORT - 150L YEAST)
There are several types of Yeast are used for alcohol fermentation
However Most common used yeast is Saccharomyces cerevisiae
So what does Yeast do living in the WORT?
once Yeast Adedd into sugar solution ,
Same time Yeast Mutiplies by feeding on the  sugar
this proces takes place for 5 to 6 days
Then yeast will consume all sugar contains in the solution
Producing alcohols , Carbon dioxide,  Flavors (Congeners ) and also the heat
after 5 to 7  days of fermentation completely  sugar will be consumed by the yeast
then the fermentation process will be stopped
killing all yest due to no more sugar to be consumed in the Sugar Solution
So the Liquid produced during the feremenation by Yeast calls  a WASH
In Scotland it calls a WASH
In this  WASH contains 5% to 9% Alcohol
this low alcohol contains Liquid calls WASH Before its sending to the distillation process
but In American whiskey production it calls as Beer
So this is the most Simplest and the easiet explanation
that I can provide about Alcohol Fermentation
I hope you gatta learn something today
Kindly do let me know if you have any further Questions
Also this is a very simple explenation for you to understand
the basic fermentation process by Bar Hopes
STAY TUNED
Next episode  bar hopes will talk about the 4th step in the Alcohol production
Alcohol Ditillation
HAVE A BEAUTIFUL DAY
