The differences between red and white wines go far beyond just the choice of grapes and the colour. Here are several fascinating facts about the real differences between red and white wines.
Made with Different Grapes
Fundamentally speaking, red wines are made with red grapes (Pinot Noir, Cabernet Sauvignon, etc.) and white wines are made with white grapes (Chardonnay, Pinot Grigio, etc). What’s interesting, though, is that nearly all wines we find in the marketplace were originally made from one species of grape called Vitis vinifera. Ampelographers believe that the first Vitis vinifera grapes were black grapes (e.g. red wine grapes) and that a natural mutation created the first white grapes.
For example, Pinot Noir (a black grape), Pinot Gris (a pinkish-gray grape), and Pinot Blanc (a white grape) all share the same DNA!
Made Using Different Parts of the Grape
After the grapes are picked and head to the cellar for winemaking, different processes are used to make red wine versus to make white wine. One of the most important differences is that red wines are fermented with the grape skins and seeds and white wines are not. This is because all the colour in red wine comes from the skins and seeds of the grapes.
There are a couple of special cases where this isn’t true and the result is very different tasting wines. For example, there is a type of Champagne called “Blanc de Noirs” or “white of blacks,” which is made in a similar way to white wine making and ends up to be a wine that looks like a white wine. Another example of this is White Pinot Noir, or Pinot d’Alsace.
With white wines, there is also a special method where white grapes are fermented with the skins and seeds of the white grapes. Wines made with this technique are referred to as Orange Wines, and they taste similar to red wines and have tannin. This technique is still quite rare and the wines are unlike any other!
Made with Different Wine Making Methods
Red wines are loved for their soft, rich, and velvety flavours, whereas white wines are loved for their zesty acidity, floral aromas, and pure fruit notes. To achieve these results, winemakers enlist two very different methods of winemaking. The largest difference between red winemaking and white winemaking is the oxidation that causes the wines to lose their floral and fruit notes in exchange for rich, nutty flavours and more smoothness. To increase oxygen, winemakers use oak barrels because they breathe and allow the wine to ingress oxygen. To reduce the exposure to oxygen, winemakers use stainless steel tanks, which ensures that wines retain their fruitiness and flower flavours.
Each Type Has Different Chemical Compounds
So, the big question remains: “Which type of wine is better for you?”
Well, since all the health benefits associated with wine are found in the skins and seeds of the wine grape, then red wines are the style of wine that’s commonly considered “better” for you. That said, not all red wines are equally!
