Tangent Membranes Inc

Ultrafiltration is a process by which wine or juice passes through a membrane and becomes clarified. Tighter than what is commonly referred to as ‘crossflow,’ ultrafiltration removes undesirable color and flavors. For color removal in whites the technique is to remove the right amount while retaining as much of the desired flavor. When removing astringency and other off flavors in reds the trick is to not remove much color. Additional factors include the age of the wine, temperature, and operating pressure. Overall loss is minimal and in many cases up to 95% recovery is possible. Let us help bring your wine to its fullest potential.
