DualFine is a two-stage clarifying agent that is specifically designed for use in clarifying wine. It is an excellent tool for winemakers who want to achieve a clear and visually appealing finished product. However, it is important to note that DualFine may not be effective in clearing pectin haze or wines made with hard water.
So when should you use DualFine? Well, the answer depends on the specific needs of your wine and the desired clarity you are aiming for. Generally, DualFine is used towards the end of the winemaking process, after fermentation has completed and the wine has been racked off any sediment.
The first stage of DualFine involves the addition of Pack 1, which contains Kieselsol. Kieselsol is a form of amorphous silica that works as a fining agent to help remove small particles and haze from the wine. To use DualFine, simply stir in Pack 1 and then allow the wine to sit for a minimum of 1 hour. During this time, the Kieselsol will start to bind with the unwanted particles in the wine, helping to clarify it.
After the minimum waiting time has passed, you can proceed to the second stage of DualFine by adding Pack 2, which contains Chitosan. Chitosan is derived from the shells of crustaceans and acts as a positively charged fining agent. It works by attracting and binding with the negatively charged particles in the wine, forming larger particles that can easily settle out. Once Pack 2 is added, allow the wine to sit for an additional 12-48 hours to allow the Chitosan to work its magic.
It is important to note that DualFine may not be effective in clarifying wines with pectin haze. Pectin haze is caused by the presence of pectins, which are natural substances found in fruits. If your wine has a pectin haze, you may need to explore other clarifying agents or techniques specifically designed to address this issue.
Additionally, wines made with hard water may also not respond well to DualFine. Hard water contains high levels of minerals, which can interact with the fining agents and prevent them from working effectively. In such cases, it may be necessary to use alternative clarifying methods or seek professional advice.
DualFine is a valuable tool for winemakers looking to achieve clarity in their wines. It should be used towards the end of the winemaking process, after fermentation has completed and the wine has been racked. While DualFine may not be effective in clearing pectin haze or wines made with hard water, it can be a reliable option for many other types of wines. Remember to follow the instructions provided with the product and allow sufficient time for the clarifying process to take place.
