   Filtration
   The removal of suspended solid particles in a wine by passing it through a filter. It can be a useful alternative to allowing the solid particles to settle naturally, thereby speeding up the winemaking process, or it can be used in cases where the wine won't clear naturally. But it is a controversial practice. Opponents to filtration claim that it strips out some of the flavour, and marketing people consequently use the term 'unfiltered' to help sell wines that haven't been treated in this way. Is filtration always bad, though? Like many winemaking decisions, it's a question of balance. Sometimes filtration is necessary, sometimes it isn't.

    Filtration
    `Filtration` is a mechanical/physical operation which is used for the separation of solids from fluids (liquids or gases) by interposing a medium to fluid flow through which the fluid can pass, but the solids (or at least part of the solids) in the fluid are retained. It has to be emphasized that the separation is NOT complete, and it will depend on the pore size and the thickness of the medium as well as the mechanisms that occur during filtrati...
