Indigenous wines from the Thracian Lowlands region recognized as a Protected Geographical Indication (PGI) region are various in terms of colors. The grape variety is the main parameter that determines the color of the wine. Pinot noir for example is made of black grapes and their skins give the drink its color. These red grapes usually produce red wine, but the intensity can still vary. The climate also has an influence on the color of the drink – in general, if the wine has been aged in a cool environment, its color is lighter. It should be noted, however, that this rule is not absolute, as other elements can play a role in climate, namely orientation to the sun and altitude. These other parameters can affect the intensity of the color of the wine. Vinification is also one of the parameters that give a wine its color. A wine with an intense red color is likely to have undergone a stronger extraction process.
In the category of white wines and wines with a lighter color, such as champagne or sparkling wine, the color can range from greenish-yellow to rusty. White wine may be straw yellow, greenish-gold, pale gold, yellowish gold, old gold, light amber or dark amber. In the range of white wines, there are dry white wines and sweet wines, which are usually more or less pale in color. Sweet wines range in color from golden yellow to amber.
