What is wine?
Quick answer
Wine is an alcoholic beverage made by fermenting fresh grape juice. Yeast converts the natural sugars in grapes into alcohol and carbon dioxide, typically producing a drink between 8% and 16% ABV.
Detailed answer
At its simplest, wine is fermented grape juice — but that one-liner barely scratches the surface. What makes wine endlessly fascinating is how much the final taste depends on where the grapes grew, which variety was picked, and what the winemaker decided to do (or not do) in the cellar.
The basic process hasn't changed in thousands of years: crush grapes, let yeast eat the sugar, and you get alcohol plus CO₂. Modern winemaking adds precision — temperature-controlled fermentation, oak aging, blending — but the core chemistry is the same one Georgians stumbled on 8,000 years ago in clay pots called qvevri.
There are five main wine families: still wines (red, white, rosé), sparkling wines (Champagne, Prosecco, Cava), fortified wines (Port, Sherry), naturally sweet wines, and dessert wines. Each uses a different technique to achieve its character — for instance, sparkling wines undergo a second fermentation that traps CO₂ in the bottle.
With over 10,000 grape varieties catalogued worldwide and vineyards on every continent except Antarctica, the world of wine is vast. The good news? You don't need to know it all. Start with what you enjoy, and let curiosity guide you from there.
