Viinintuotannossa

Viinintuotannossa refers to the process of winemaking in Finnish. This complex and ancient practice involves transforming grape juice into wine through fermentation. The journey begins with the harvest of ripe grapes, where the quality of the fruit is paramount. Grapes are typically crushed to release their juice, known as must. For red wines, the grape skins, seeds, and sometimes stems are left in contact with the must during fermentation, imparting color, tannins, and flavor. White wines are usually fermented from juice that has been separated from the skins.

The core of winemaking is fermentation, a biological process where yeast, either naturally present on the grapes or added by the winemaker, consumes the sugars in the must and converts them into alcohol and carbon dioxide. This stage requires careful temperature control to ensure optimal yeast activity and to preserve delicate aromas. After fermentation, the wine may undergo various treatments. Malolactic fermentation, a secondary bacterial fermentation, can convert sharp malic acid into softer lactic acid, adding complexity and stability.

Aging is another crucial step, often taking place in oak barrels or stainless steel tanks. Oak barrels can impart flavors of vanilla, spice, and toast, while also allowing for slow oxidation, which softens tannins and develops more nuanced aromas. Stainless steel tanks, on the other hand, are used to preserve the fresh, fruity character of wines. Finally, the wine is clarified, filtered, and bottled, ready for consumption. The specific techniques and choices made at each stage significantly influence the final character and quality of the wine.
