Cleanliness of Wine
We as humans live with our eyes, especially when it comes to food or drink. If you don’t like what you see or the product is not visually appealing, chances are you won’t taste it. Wine is no different in this regard. Cleanliness is the most important aspect. Aside from sediment in reds from age or non-filtering, all wine should be clear and clean. Any wine that is cloudy, hazy, has an oil slick on the surface, or has suspended particles floating in it, says there’s probably some sort of problem with it, ranging from chemical and bacterial to winemaking. You could ignore what you see and taste it, but chances are, most folks would not. Thus, visual cleanliness of a wine in a glass will ultimately determine whether you sip it or not.
