Choosing a Filtering System: Techniques - WineMaker Magazine. Winemaking is not a science but rather an art.
There are many opinions on the pros and cons of the various processes that winemakers use.

Some advocate the practice of filtration, others believe that fining is sufficient, while many traditionalists simply let nature take its course.
Emile Peynaud, one of the greatest enologists of the twentieth century, commented on “the sensory consequences of filtering” in his book “Knowing and Making Wine” (John Wiley & Sons, 1984). “The mechanical action of filtering has never had a negative influence on quality.” Make your own wine, beer, liqueur and cheese.
