Its application improves must yield, color and aromatic compound extraction, colloidal stability, and product clarity. Furthermore, it helps reduce fermentation and clarification times, improves filterability, and allows for the precise correction of technical imperfections without altering the wine’s authenticity.
Benefits of enzymes in wine products
Oenological enzymes are applied during different stages of production, providing key benefits that impact both the process and the final product.
Our enzymes offer benefits such as:
Higher extraction efficiency
During maceration and pressing, enzymes such as pectinase, cellulase, and hemicellulase break down the cell walls of the grapes, facilitating a greater release of juice and phenolic compounds. This not only increases must yield but also improves the aromatic profile and body of the wine.
Clarity and filterability
One of the major challenges in winemaking is the efficient removal of turbidity. Pectins present in the must hinder clarification. Pectinases break down these viscous structures, significantly improving settling, filtration, and the clarity of the wine.
Colloidal stability
Complexes formed between proteins, polysaccharides, and other compounds can cause visual instabilities. Some enzymes reduce the colloidal charge, helping to prevent unwanted precipitation during storage or after bottling.
Intensification of color and organoleptic profile
In red winemaking, the release of anthocyanins and tannins depends on the efficient breakdown of cell walls. Specific enzymes involved in color extraction contribute to producing more intense wines with greater color stability and a rounder, more persistent mouthfeel.
Process optimization
Enzymes reduce maceration, clarification, and pressing times. This allows for greater efficiency in the winery, facilitates operational scheduling, and decreases the use of resources such as water and energy, which also has a positive impact on the sustainability of the process.
Practical examples
Application in white and pink grapes
In these cases, the main objective is to achieve a clean extraction of the must and a stable fermentation. Pectinases help reduce the viscosity of the juice, facilitating its separation and clarification. This improves clarity and allows for fresher wines with more defined primary aromas.
Winemaking of red wines with short maceration
To achieve intense color quickly, enzyme mixtures with specific activity against cellulose and hemicellulose are used. This allows for the extraction of more anthocyanins in a reduced period, without compromising the wine’s structure or generating excessive astringency.
Clarification without aggressive treatments
In situations requiring rapid clarification, the use of enzymes eliminates the need for intensive heat or chemical treatments. The controlled degradation of polysaccharides and proteins facilitates natural sedimentation and efficient filtration.
Ease of use in the warehouse
Winemaking enzymes are available in liquid or granular form and can be easily dosed according to the grape variety, the desired wine style, and the working conditions. Their application does not interfere with yeasts and is compatible with both traditional and more innovative processes.
Reduction of methanol formation
The enzymatic hydrolysis of pectins using specific pectinases allows for limiting methanol release during fermentation, especially in varieties with high concentrations of methylated pectins. This application is key to complying with food safety regulations and improving the quality of the final wine.
Optimization of aromatic extraction
Certain enzymes release aromatic compounds bound to the cell walls of grapes, such as terpenes and norisoprenoids. Their application allows for enhancing the sensory profile of wine from early stages, improving aromatic intensity and complexity without the need for external additives.
Enzymes in wine color
The intensity and stability of color is one of the most valued attributes in red wines. This color comes primarily from anthocyanins, compounds found in the grape skins, the release of which depends on the degree of cell rupture during maceration.
Enzymes such as cellulases, hemicellulases, and pectinases allow for a more effective breakdown of these structures, increasing the solubilization of anthocyanins and their subsequent fixation in the medium. This results in wines with greater visual intensity and improved resistance to color oxidation over time.
Furthermore, this enzymatic extraction eliminates the need for excessively long maceration, which can lead to excessive tannins or the unwanted extraction of plant compounds. This results in a balanced wine, with a combination of color, body, and elegance in the final product.
Wine analysis
The application of enzymes also has significant technical value in wine analysis and quality control. Some enzymes are used in the laboratory to measure the concentration of compounds such as glucose, fructose, malic acid, or tartaric acid through specific enzymatic reactions that allow for precise and rapid quantification.
Furthermore, during production, the monitoring of parameters such as viscosity, the presence of pectins or protein stability can be improved with the incorporation of enzymes that facilitate the sensory or instrumental analysis of the wine.
These tools allow for more precise technical decisions, detection of fermentation problems, prediction of instabilities, and correction of deviations without the need for subsequent corrective treatments.
