How to Recognize Table Grapes Vs. Wine Grapes

When you think of grapes, do you imagine a bunch of grapes ready to eat or a stretch of vineyards? They're not the same thing: there are in fact two main types of grapes, designed for different uses. If you pictured a plate of grapes, then you had in mind table grapes, that is, the grapes you buy at the supermarket or greengrocer, to eat. If, on the other hand, you pictured a vineyard, then you thought of wine grapes, which can be used to produce and market bottles of wine.

Although both belong to the same species, they have very different characteristics. Today we'll explain how to recognize table grapes and wine grapes and how they differ.

Table Grapes Vs. Wine Grapes

Both table grapes and wine grapes belong to the same species, Vitis Vinifera. Over time, cultivars have been selected that have led to this clear differentiation. Let's start with table grapes: these are primarily intended for direct consumption. What are their main characteristics?

• The grapes are larger, fleshier and crispier.
• The peel is thin and easy to chew.
• The pulp is firm and juicy.
• The flavor is sweet, thanks to a high sugar content.
• Mild or absent aromatic profile.
• It is often seedless (but not necessarily).
• It is always harvested when fully ripe.

As for wine grapes, we note characteristics that are in some cases opposite:

• The grapes are smaller in size.
• The peel is thicker.
• The pulp is juicy, but not crunchy.
• The flavor is intense and often veers towards sour or bitter.
• The sugar content is medium-high, but varies depending on the wine the winemaker intends to produce.
• Complex aromatic precursors are present (the substances that, during fermentation, will give rise to the aromas of the wine).
• High levels of acidity are present.
• The grape always contains seeds.
• It is not always harvested when fully ripe, indeed, the time of harvest varies depending on the intentions of the winemaker, the type of grape, and the territory it belongs to.

These differences are mainly due to the different ways in which these types of grapes are used.

Table grapes are those you can eat as they are, freshly washed: for this reason, they must have specific characteristics that make them palatable. It's no coincidence that the berries are large, crisp, and juicy, with thin skin and a sweet flavor.

Wine grapes, on the other hand, are a different story: they're not eaten for pleasure, but are carefully selected to be transformed into wine. What matters is not so much the taste of the grape, but rather the fruit's internal composition: sugars, acidity, aromatic substances, and tannins. Even if the flavor may seem harsh or unpleasant, that particular balance is essential for obtaining a harmonious, structured, and aromatic wine.

Can You Make Wine With Table Grapes?

In theory, yes, but with some limitations. You can use table grapes to make wine at home, but only for personal consumption: the law prohibits the sale of wine made from grapes not authorized for winemaking.

There's also a more interesting reason: wine made from table grapes is almost always very simple, not very aromatic, and lacks the structure that makes a wine complex and long-lasting. This is because table grapes have lower acidity, few aromatic precursors, and often a "flat" sweetness that doesn't withstand fermentation.

In practice? Yes, you can make wine with table grapes, with realistic expectations, and it will be ready to drink immediately, within a few weeks.

Can You Eat Wine Grapes?

Technically, yes, but it's not meant to be eaten. Producers sometimes taste wine grapes to monitor sugar, acidity, and ripeness: it's a useful way to decide the exact time to harvest. But that doesn't mean it's enjoyable to eat.

Wine grapes, in fact, have small berries, thick skin, and often a sour or bitter flavor. They also contain many seeds, and their aromatic profile only develops after fermentation. So, yes, you can taste them, but don't expect the sweetness and crunchiness of table grapes.
