Red wine and its mysterious colour
Purple, ruby, dark red. Pale or opaque. About the colour and intensity we learn a lot about a red wine. Character, age or even the grape variety can be appreciated. Very well known and important grape varieties of red wine are Pinot Noir, Cabernet Sauvignon or the dark red Syrah or also known as Shiraz. In a young red wine, purple tones dominate. The older the red wine is, the more the colour changes to reddish brown. The berry skin also has a strong influence on the colour of the red wine. The pigments in the skin of the berries give the red wine a strong colour note. The must of the grapes is white.

Production of red wine
In addition to the grapes used, red wine differs from other types of wine such as white or rosé wine in terms of the production process. Dark grape varieties are used for the production of red wine. Apart from the choice of grape variety, the main difference between red wine and white wine lies in the fermentation process. While for white wine the pressed must ferments, for red wine fermentation the mash is used. This is a mixture of the juice, skin and pulp of the grapes. Usually the maceration lasts 8 to 14 days. A longer maceration tends to result in heavier and stronger red wines. For many red wines, the so-called malolactic fermentation follows the maceration. In this process bacteria convert the intensive malic acid into lactic acid. In white wines, this second fermentation takes place less often than in red wines, which is why white wines usually have more acidity.

Important varieties of red wine
Many wines do not consist of only one grape variety. When different varieties are mixed, one speaks of a blend or cuvée. In France this combination is called Assemblage. The most important red wine grape varieties are Merlot, Cabernet Sauvignon, Syrah, Tempranillo, Garnacha, Pinot Noir and Sangiovese. The main differences are the colour, the tannin and sugar content and the acidity. During the wine storage, it changes its taste and colour. During bottle ageing, the wine gradually develops its complexity and maturity. Once this peak is passed, it loses its taste and colour. For optimal wine storage, both temperature and humidity must be right. The temperature should ideally be between 10 and 13 degrees Celsius.
