  Sensory and Chemical Effects of Cross-Flow Filtration on White and Red Wines

  Peter Buffon, Hildegarde Heymann and David E. Block; Am. J. Enol. Vitic April 2014 ajev.2014.13090

  Cross-flow filtration is an increasingly common post-fermentation process in the wine industry. Because of the nature of the membranes used in this process, our hypothesis was that cross-flow filtr...
