As an expert sommelier and brewer, I have come across many different clearing aids in my career. One such clearing aid that I have used is the FermFast DualFine. This product is specifically designed for beer, wine, and spirits, and it is a dual-stage clearing aid.
The purpose of the DualFine is to help clarify and improve the appearance of the final product. After the fermentation process is complete, there can be residual particles or haze in the liquid that can affect the visual appeal of the beverage. The DualFine helps to remove these particles, resulting in a clearer and more visually appealing end product.
The DualFine comes in two packets – A1 Kieselsol and A2 Chitosan. Each packet serves a specific purpose in the clearing process. In this answer, I will focus on the A1 Kieselsol packet.
To use the DualFine, you simply need to gently stir the entire contents of the A1 Kieselsol packet into your beer, wine, or spirits after fermentation is complete. It is important to note that the fermentation process should be fully finished before adding the clearing aid, as any ongoing fermentation can interfere with the effectiveness of the product.
Kieselsol, which is the main ingredient in the A1 packet, is a natural fining agent derived from silica. It helps to bind and remove particles suspended in the liquid, such as yeast cells, proteins, or tannins. By adding Kieselsol, you are promoting the settling of these particles, allowing them to be easily removed during the subsequent clearing stage.
I have personally used the FermFast DualFine in my brewing and winemaking processes, and I have found it to be quite effective in improving the clarity of the final product. It is important to follow the instructions provided by the manufacturer and to use the product in the recommended quantities for optimal results.
The FermFast DualFine is a dual-stage clearing aid that helps improve the appearance of beer, wine, and spirits. The A1 Kieselsol packet is specifically designed to remove suspended particles and promote settling. By incorporating this clearing aid into your brewing or winemaking process, you can achieve a clearer and more visually appealing end product.
