What is Winemaking?
Winemaking is the process that changes grape juice into wine.
Different winemaking techniques can create completely different wine styles.
- Making red and rosé wine
- Making white wine
- Making sweet wine
- Making sparkling wine
- Making fortified wine
Making White Wine
Making Red and Rosé Wine
Red Wine
Red wines are typically drained off the skins at the end of alcoholic fermentation.
Rosé Wine
Rosés are drained off the skins after only a short maceration. Fermentation continues without the skins.
Making Sweet Wine
Residual sugar is the sugar left in wine after fermentation.
Different levels of residual sugar determine the sweetness of wine.
Example: Sauternes
Grapes with concentrated sugar
↓
Alcoholic fermentation
↓
Yeast stops fermenting before all sugar becomes alcohol
↓
Bottling
Example: Moscato d'Asti
Ripe grapes
↓
Alcoholic fermentation
↓
Remove or kill the yeast

Bottling
Concentration of Sugar
Sugar concentration in grapes determines potential alcohol, sweetness balance, and final wine profile.
Extra RipeningLonger hang-time increases sugar levels and flavor intensity before harvest.
Shriveling / Noble RotWater loss concentrates juice, creating dense sweetness and aromatic complexity.
Frozen GrapesIce wine production presses frozen berries to extract highly concentrated must.
Making Sparkling Wine
Sparkling wine bubbles are created by dissolved carbon dioxide gas produced naturally during fermentation.
Example: Champagne, Crémant, Cava
