What are the Differences between Red Wines and White Wines?
Aside from the obvious colour differences, red and white wines can vary in numerous ways. The differences in their composition can affect their taste, the foods they should be paired with, and their ability to age. Different types of grapes may be used for each type of wine, but in some instances the same grape varietal can produce both a red and white type with contrasting flavours and bouquets.
Fermentation Process
The first difference to be mentioned regarding red wine and white wine is the way they’re made. Red wine will generally be made form black grapes while whites can be made from black or green or a combination of both.
When making red wine, the manufacturer leaves the skins, seeds, and stems in the fermenting vat with the juices to allow the extra tannins to leech into the liquid. For white wine the juice would first be extracted from the skins, seeds, and stems then fermented on its own. Blush wine is produced by removing the skins part way through the fermentation process.
Taste and Tannins
The tannins in wine that give it a more bitter flavour come mostly from the skins. Because red wines are fermented in a vat with the skin, they a have higher tannin content and generally have a more dry and bitter flavour. Whites usually taste fresher and crisper as their tannin content is lower.
Aging
The tannins in wine help to preserve it, so for the most part, red wines can be aged longer and will taste better with age as the tannins mellow. Some of the tannins can be removed to make the wine ready for immediate consumption, which is why white wines are usually ready to drink much more quickly as they naturally have a lower tannin content.
Flavours
Generally speaking, red wines will have a more bitter, mouth puckering taste while whites will be much smoother and sweeter. Reds may taste heavier and full-bodied and lights may be fresher and fruitier, but in some cases those characteristics could be reversed. Tasting as many wines as possible will give you the best idea of what to expect with each type and can give you a better appreciation of the differences between white and red wine.
