Wine clarification is vital to guarantee wine clarity and shelf life. Diatomaceous earth (DE) filtration has long been the mainstream clarification method for wineries, yet it suffers from disposable consumables, solid waste, unstable filtration and loss of wine aroma. Ceramic cross-flow membrane filtration serves as an advanced alternative. This article compares the two technologies and introduces the advantages of ceramic membrane, including stable clarification, reusable membrane elements, less flavor loss and automatic operation. It helps wineries select proper wine clarification equipment.
