Once in a while, you may see a label announce that the wine is \u201cunfiltered\u201d. This does not mean the winemaker was smoking a Camel cigarette when the wine was bottled (though, it doesn’t mean he or she WASN’T, either), nor does it mean that you need to pour the wine through a coffee filter before drinking it. Basically, it\u2019s an explanation for the wine\u2019s lack of clarity.<\/p>\n
For the last 25 or so years, wineries have used fining and filtration techniques to make a wine appear crystal-clear. This makes for a more attractive and trustworthy product. Most wines sold at retail today are filtered, and as a result you can see right through them (this is most obvious with white wines).<\/p>\n
A wine is filtered in one or more of several ways. For example, sterile filtration uses micropore filters, which are fine enough to remove yeast cells, and thus prevent a second fermentation inside the bottle. On the other hand, depth (or sheet) filtration is not unlike the use of a coffee filter, though is a bit more sophisticated than the typical #4 cone you use in your coffeemaker. The process relies on a thick layer of fine material (diatomaceous earth, cellulose powder, perlite, etc.) to trap and remove small particles. There are other methods as well \u2014 membrane filtration is common \u2014 and there are pros and cons for each process. Regardless of the way it\u2019s done, the goal is to remove any undesirable elements and produce a stable, clear liquid.<\/p>\n
However, these filtering processes may also remove elements that affect the flavors and aromas of a wine, so some winemakers choose not to filter. They believe that filtering strips the wine of its true character, and employ other methods of getting the wine as clear as possible (racking, cold stabilization, and other old-school techniques are the alternative). There are also wineries that avoid filtering \u2014 or keep it to an absolute minimum \u2014 to maintain organic status.<\/p>\n
Does an unfiltered wine taste better than a filtered one? Maybe \u2014 it all depends on the individual. For many, it can be more of a visual thing than a flavor issue. Some people are put off by a wine that is not completely clear, while others feel a cloudy wine is more \u201cnatural\u201d.<\/p>\n","protected":false},"excerpt":{"rendered":"
