DualFine is a product that is specifically designed to assist in the clarification process of wine. It comes in the form of two pre-mixed pouches, one containing kieselsol and the other containing chitosan. These two components work together to create both strong negative and strong positive charges in the wine, which in turn allows for larger yeast clumping and faster clearing.
The first component, kieselsol, is derived from silicon dioxide and serves as a fining agent. It works by creating a negative charge in the wine, which attracts the positively charged particles present, such as yeast cells and other suspended solids. This helps to aggregate these particles together, forming larger clumps that are easier to remove during the clarification process.
The second component, chitosan, is derived from the shells of crustaceans such as shrimp or crab. It acts as a positively charged fining agent, which helps to further accelerate the clarification process. The positively charged chitosan molecules are attracted to the negatively charged particles in the wine, forming larger clumps and aiding in their removal.
When these two components are used together, they create a synergistic effect, enhancing the efficiency of the clarification process. The combination of the strong negative and positive charges helps to attract and bind a wide range of particles, including yeast cells, proteins, and tannins, among others. This results in a faster and more effective clearing of the wine, leaving it with a cleaner and brighter appearance.
To use DualFine, one pouch is typically sufficient to clear a 5 or 6 gallon carboy. The contents of the pouches are simply added to the wine, following the instructions provided. It is important to note that DualFine is best used after fermentation is complete and the wine has been racked off the sediment.
I have personally used DualFine in my winemaking endeavors, and I have found it to be a reliable and effective product. It significantly reduces the time required for the clarification process, allowing me to enjoy my homemade wines sooner. The clarity and brightness of the final product are noticeably improved, making for a more visually appealing presentation.
DualFine works by utilizing the unique properties of kieselsol and chitosan to create strong negative and positive charges in the wine. This facilitates the aggregation of suspended particles, resulting in faster and more efficient clarification. The use of DualFine can greatly enhance the overall quality and appearance of homemade wines, providing a professional touch to the winemaking process.
