PROCESS OF MANUFACTURING OF WINES

After having brief knowledge about wines and grapes i am going to share the different stages of the wine manufacturing.
each and every stage is very important and should done nicely to get the good wine. the stasges are as follows:-


  • Crushing/De-stemming:- The harvested grapes are dumped into a large HOPPER called crusher which cracks the grapes, and allowing the juice to flow.
in this process the stems of the grapes  separated which then again sent to the grapes farm and used as the fertilizer.  the crushed grapes and the juice are kept toghether.
  • Fermentation:- In this process, yeast converted natural sugar into ethyl alcohol and CO2. this natural yeast is called as SACCHAROMYCES CEREVISIAE. The temperature increases during this process and the ideal temperature should be from 15 to 18' c. To cool the vats by cold water running through the metal coils inside the vats. and this process continues till all sugar is converted into the alcohol. all the casks are well sealed to avoid the oxidation.
  • Racking:- It is a natural clarifying process that aids in settling suspended particles in the wine and removing them from contact with it.  After the fermentation process the young wine is full of impurities and sediments that are called LEES. All the impurities settle down after fermentation stops  and then the wine is transferred into another casks and filled to the brim (edge of the cask) and sealed well to avoid the oxygen to contact with the wine.
  • Finning:- This process is done to obtain the clarity in wine. the impurities are mixed with the wine even after the racking process so to extract them this process is done. And by this the stability of wine also increases over a period. in this process we can use the finning agents such as:- Egg white, gelatin isinglass (Bladder of sturgeon) and the OX blood.  This also makes the wine bright and clear.
  • Maturation and Ageing:- This is the process of Ageing when the wine becomes Mellow.  For this the wine kept in the casks and the air circulates through the pores of the cask which makes the wine mature.  And when the wine is fully mature its qualtiy starts to decline. the process of maturation continues till the bottling. After a certain time the wine changes its color. White wines changes to greenish to golden straw colour and the red wines into purple to garnet colour.
  • Blending:- In this process, different qualities of wine are mixed to produce a standard quality wine. Vintage wines are not blended but to bring up the standard quality of wine of different years, they are mixed with vintage wines to produce the standard quality of wine.
  • Bottling:- Before the bottling of wines all the equipments and bottles are sterilized by passing sulphur dioxide and the washing in boiling water. the cork is also sterilize so that it cannot spoil the wine. first put the cork in the bottle and then dip the neck of the bottle into wax which makes it air tight and then wrapped into the metal foil.
This is the process of making wines.  This post is definitely helpful to you .It is the brief detail and if you want the details in explain you can send me the mail or contact with me.  thanks to you all.
