All about grape varieties
When you choose a bottle of wine , its label gives you some key information, which constitute clues about the type and aromas of this wine .
One of these pieces of information is the grape variety(ies) used. Indeed, it is the grape variety that is the basis of each type of wine.
What is a varietal ?
Wine is produced from grapes. The vine, on which this grape grows, can belong to various varieties . It is these different varieties of vines that are called “grape varieties”.
So when you choose a grape variety, you are choosing the type of grape (or mix of grapes) used to create your wine. Some wines are said to be "monovarietal" , which means that they are made from a single type of cultivated vine, while others are made from blends of different grape varieties .
Note that there are over 8,000 different types, sometimes used very locally or sometimes in dozens of countries at once. There are wine grape varieties and table grape varieties, used for table grapes.
We can distinguish two main families of grapes:
- “White” grapes : they have a white juice used for most white wines,
- “Black” grapes : they can have a red juice (used for red wines) or a white juice (used for white wines).
To identify the grape variety to which a vine belongs, it is necessary to observe the appearance of the plant, such as the morphology of the leaf, the shape of the bud and the color of the clusters . The science of studying the differences between grape varieties is called “ampelography”.
How are the different grape varieties distinguished?
Knowing that there are different types of grapes is good. Understanding why it is important to distinguish them is better.
Indeed, each grape variety gives the wine a different taste, aromas and characteristics . The reason for this lies in the characteristics of the grape itself.
Each type of grape has a particular taste , even before being transformed to create wine. These particular aromas are the basis of the characteristics presented by the wine at the end of the process. Thus, while some grape varieties offer aromas considered relatively neutral, others will have more floral characteristics, such as Muscat, or vegetal characteristics, such as Sauvignon Blanc.
The acidity level
Not all grape varieties are equal, in terms of acidity either. Some grape varieties are naturally very acidic, which greatly influences the wine produced .
A grape that has a very thick skin gives more tannins , compared to a grape with a thin skin.
The size of the grape
The logic is the same: the more skin there is, the more tannins the grape will deliver . However, if a grape is small it will contain less juice than skin.
This is not insignificant, because the characteristics of the grape are subsequently transmitted to the wine. This is why it is useful to know how to recognize certain grape varieties, which are more common than others.
The main grape varieties and their characteristics
Unless you are a real expert, it is quite difficult to know all the grape varieties that exist. It is nevertheless very useful to know some of them and to identify those that we prefer .
Here is some information about some of the most used grape varieties in France:

Cabernet Sauvignon is the second most used red grape variety , after Merlot. Its favorite land is Bordeaux, where it has acquired its letters of nobility, in particular thanks to Médoc and Graves. However, it is also used for many blends in the South and South West.

Grenache is a purely Mediterranean grape variety . It has a particular success in Spain. The wine it produces has a full-bodied character .
