Inadequate Equipment:
The wine making equipments may look same as home utensils but they are made of some special materials. Pails, carboys, air locks and spoons are the major equipments needed to prepare wine. Reusing plastic pails which is previously held food products is a major mistake. The food order may remain in the pail and it will taint the wine. Pails made from plastics cannot be used for wine making.
Cleaning and Sanitizing:
The specific reason for failure in wine making is lack of cleaning and sanitation. Cleaning is the process of removing the chemicals from the equipments. Sanitizing is the process of preventing the growth of spoilage organisms in the equipments. All the process carried out with wine preparation should be clean and properly sanitized to avoid failure of your batch.
Bad Water:
Water is not a very big problem in this preparation. The ordinary water which you used for drinking is quite fit for wine preparation. If the mineral like iron content is high in water then it is unfit for wine making process. The water get from water softener is also not used for this process.
Poor Yeast Handling:
The yeast can be re-hydrated or can be directly sprinkle on the juice as per your wish. The packet of dried yeast is of good quality and it can be used directly. The major problem with this is the people should have a clear idea before going for re-hydration. The improper re-hydration will spoil the goodness of wine.
Adding Sulfite and Sorbate at the Wrong Time:
The stabilizers like Sulfite and Sorbate should be used to inhibit the yeast activity. The stabilizers should be added in a proper time. If you add it too earlier then the fermenting process cannot be completed successfully. The sorbate added in the first day will make the yeast not to get active which in turn spoils the fermentation process.
