Video sum up: What makes a wine a particular color?

Although this question looks silly the answer is really complex.

Basically:

• white wines comes from white grapes
• red wines comes from red grapes

After a lot of other factors have to be taken into account:

• The longer you live the skin of the grape in contact with the wine the darker the wine would become. For example: Rosé wines are red wine where grape skins have been exposed to wine only for a limited period of time.
• Different grapes will give different depth of color. For example Viognier and Pinot Grigio give a very light color.
• It also depends where the wine is aged: if the wine is aged in steel it will not add any additional color. But if the wine is aged in oak it will be darker.

After it is all a winemaker choice.
