What is the subtlety behind the color of red wine?

When tasting wine, the first step we have to do is to "look at the face". The reason why we should pay attention to the color of liquor is not only because it is a measure of wine appearance, but also because it hides many mysteries about brewing technology, quality and style.


1、 Where does the color of wine come from?


The color of wine comes from the grape skin. Whether the grape juice contacts with the grape skin and the contact intensity are the main reasons for the color difference of wine. Red wine is brewed from red grapes. From maceration to fermentation, grape juice always keeps in contact with the peel, which can fully extract the pigment substances. In addition, during the fermentation process, the staff will also increase the extraction efforts through pumpover, punchdown, and rackandreturn.


The brewing of white wine is quite special. It can be made from white grapes or red grapes. However, when making white wine, soaking is an optional process, and grapes must be pressed before fermentation to separate grape juice from solid substances such as grape seeds and grape skins containing pigments. Not only that, the pressed juice usually needs to be clarified before it can enter the fermentation process. Because the contact time between grape juice and peel is very short, no matter whether its raw material is white grapes or red grapes, the finished wine will only show light colors such as lemon yellow and golden yellow.


2、 What can the color of wine tell us?


In the systematic wine tasting method, observing the color of liquor is an indispensable step. By observing the color, drinkers can preliminarily judge whether there are defects in the wine. Most defective wines are gray in color and at least have a hint of brown. It should be noted that some wines in good condition but aged for a period of time will also show brown, especially those aged in oak barrels for a long time. Secondly, the color of liquor can roughly reflect the length of wine age. With the growth of wine age, the color of red wine will gradually become lighter, from the initial purplish red to ruby red, then to garnet red, and the color of white wine will become darker and darker, from lemon yellow to golden yellow, and finally to amber.


Moreover, the darker the color of wine, the fuller and heavier the wine. As for white wine, we can also know whether it has been aged in oak barrels from the depth of liquor color. For example, light yellow Chardonnay wines are generally not aged in oak barrels, while golden Chardonnay wines are mostly aged in oak barrels. In addition, the color transparency of unfiltered wine before bottling will be low.


3、 How to observe the color of wine when tasting?


Different lighting environments and backgrounds will affect our judgment of liquor color. To make an accurate assessment, we should use a pure white tablecloth or napkin as the background under the condition of sufficient natural light, hold the cup stem and tilt the wine cup 30-45 degrees, and watch the color of the wine against the white background.


The edges of white wine and most pink wine are almost colorless, so the color should be identified according to the central tone of the liquor. When observing the color of red wine, we need to shift the visual focus to the edge color band of the wine, because the central tone of red wine is too deep and it is difficult to identify. In addition to paying attention to the hue, we also need to pay attention to the edge zone extended by the liquor while observing the color. The wider the edge band, the lighter the color of the wine, and vice versa.
