In modern times, many wines - especially mass-produced labels - are run through a fine-pored filter aimed at removing any tiny particles that may remain in suspension and give a hazy appearance to the finished wine.

Some wine makers, especially those at smaller, artisanal wineries, believe that this process may strip subtle aromas and flavors from the finished wine, along with the haze, and so they make their wines by more traditional processes. The clarity may suffer (although most well-made wines come out clear even without filtering), but these wines are certainly as good, and perhaps even better, than the industrial-type wines.
