Dan Karlsen, Chalone Winery, Soledad, CA, details the Organoleptic benefits of their Oenoflow Crossflow System. ""Sometimes you need to let go of preconceived ideas and go with what tastes better". He and his assistants did several blind tastings of wine processed with different filter equipment. Karlsen reports that the 2001 Chalone red wines that were cross-flow filtered simply tasted better. DE or pad filters, Karlsen notes, can introduce other flavors, such as mustiness or paper taste, and too much pad or DE filtering strips the wine of its flavor, weakening the structure and taste. The PALL Oenoflow crossflow filter did not produce the same results".
