Wine is one of the oldest and most popular alcoholic beverages in the world, and it comes in a variety of colours, flavours, and styles. Red wine and white wine are two of the most common types of wine, and they are distinguished by their colour. In this blog, we will explore the reasons why red wine is red and white wine is white, and the factors that contribute to these differences.
Before we dive into the science behind the colours of red and white wine, it’s worth noting that both types of wine can vary in colour, depending on a number of factors such as grape variety, winemaking techniques, and ageing. At Wine Tasting Mallorca, we offer a range of tours and tastings that allow you to experience the full spectrum of wine colours and learn about the factors that contribute to each wine’s unique characteristics.
Why is Red Wine Red?
The primary reason why red wine is red is due to the presence of tannins and pigments found in the skins of red grapes. During the winemaking process, the skins of the grapes are left in contact with the juice for a period of time, allowing the pigments and tannins to leach into the wine. This process is called maceration, and it is what gives red wine its characteristic colour, as well as its distinctive flavours and aromas.
The specific pigments responsible for the colour of red wine are called anthocyanins, which are found in higher concentrations in red grape skins than in white grape skins. Anthocyanins are sensitive to pH and can range in colour from pink to purple, depending on the acidity of the wine.
Why is White Wine White?
White wine, on the other hand, is made from white or light-coloured red grape varieties, and it typically lacks the pigments and tannins found in red wine. During the winemaking process, the skins of white grapes are removed before fermentation, so they do not have the opportunity to impart colour or tannins to the wine. Instead, the juice is fermented without the skins, resulting in a wine that is typically lighter in colour and body than red wine.
Some white wines may have a slightly yellow or golden colour, which is often the result of ageing in oak barrels or contact with dead yeast cells during the winemaking process. However, these colours are typically much lighter than the deep reds of a good red wine.
In conclusion, the colour of the wine is primarily determined by the presence or absence of pigments and tannins in the grape skins. Red wine is red because of the pigments and tannins that leach into the juice during the maceration process, while white wine is white because it is made from grapes with little to no pigments or tannins. While there are exceptions to these general rules, understanding the science behind the colours of wine can help deepen your appreciation and understanding of this beloved beverage. At Wine Tasting Mallorca, we invite you to explore the wide range of wine colours and styles through our tastings, where you can sample the best of Mallorca’s wines and learn about the unique characteristics that make each wine so special.
