A drink made by fermenting grape juice.

Wine is a drink made by the alcoholic fermentation of grape juice. Yeast feeds on the sugar in the grapes and turns it into alcohol and carbon dioxide. Most wines have 9 to 15% alcohol. Wine is made from grapes of the species Vitis vinifera, which grow on the grapevine.

It all starts in the vineyard. Viticulture looks after the vine: pruning, the trellis, the harvest. Then winemaking takes over: the grapes are crushed, the juice ferments, and the wine is aged and bottled. The science of wine is called oenology, and the study of grape varieties is ampelography.

The taste of wine depends on the variety, the climate, the soil and the people who make it. Together this is called terroir. The vintage matters too: in a warm year the grapes are sweeter, in a cool one more acidic.

There are many types of wine: still, sparkling, dessert and fortified. Sparkling wine is made, for example, by the traditional method or the Charmat method. Wine contains alcohol, so it is sold only to adults and is best drunk in moderation.

Frequently asked questions

What is wine made from?

From grape juice fermented by yeast. Wines made from other fruit are called fruit wines.

How much alcohol is in wine?

Most still wines have 9 to 15% alcohol. Fortified wines such as port or sherry are usually stronger, at 15 to 22%.

What is the difference between red and white wine?

Red wine ferments with the skins of dark grapes, which give it colour and tannins. White wine is usually made from the juice alone, without the skins.

⚠️ Wine contains alcohol: adults only, drink in moderation. Wine usually contains sulphites; egg white or milk proteins are sometimes used for fining — important for allergies and for vegans.
