The winemaking process
Harvesting: Grapes are harvested when they are ripe. The timing is critical for the sugar, acid, and flavor balance. Harvesting can be done manually or mechanically.
Crushing and pressing: The grapes are crushed to break the skins and release the juice. For white wine, the juice is typically pressed away from the skins immediately. For red wine, the skins are left with the juice during fermentation to extract color and tannins.
Fermentation: Yeast is added to the grape juice (must) to convert its sugar into alcohol and carbon dioxide.
Primary (alcoholic) fermentation: This is the main fermentation process.
Secondary (malolactic) fermentation: This is a second fermentation, common in red wines, that converts malic acid to a softer lactic acid, adding complexity to the wine.
Clarification: After fermentation, the wine is often racked (transferred from one container to another) and clarified to remove solid particles, using processes like fining or filtration.
Aging: The wine is aged, often in stainless steel tanks or oak barrels, to develop flavor and complexity. This step is also known as maturation.
Bottling: Once the wine has reached the desired age, it is bottled. The bottle is sealed with a cork or cap to prevent spoilage and preserve the wine as it continues to age.
