The biological fermentation of wine is a very delicate process that determines the quality of the wine in an important way. The sugars present in the must are transformed into alcohol and carbon dioxide, which is why this phase is so important for the quality of the final product.

What changes from normal to organic fermentation
If we talk about organic wine, the fermentation process of the must is even more particular and the method of analysis plays a fundamental role. In recent times, the sensory analysis method has been used to understand when is the best time to pick the grapes.
Once the grapes have been harvested, the maceration process begins. This is a particularly delicate moment because there may be microorganisms that could damage the final product. Even in biological fermentation and during the vinification phases, natural products can be used without the use of chemicals.

Use of yeasts, better selected
In the biological fermentation phase, where there is the transformation of the sugar present into alcohol, yeasts must be used. In organic winemaking, the yeasts must be selected and not genetically modified.
But that’s not all, because the choice of yeast also affects the taste of the wine, so it deeply changes its characteristics. You must therefore choose the most useful strain for the result you want to obtain.

Use of enzymes in wine production
Enzymes also play an essential role in the wine production process. Knowing how to choose and quantify them in a precise and constant way over time, is an added value that allows to obtain a standardized production of quality, and possibly, can also eliminate off flavours, and reduce process costs.

What we can do for you
Bict has extensive expertise in microbiology and enzymology, which is why we can offer you the best services in these areas.
We are therefore able to isolate and characterize the strains, to perform microbiological and chemical-physical analysis, to define the conditions of storage of the strain. We can also study with the customer the best solutions in terms of enzymes.
Our processes are automated through the use of robotic units, this means excellent quality and timely delivery.
