Which option is considered for white winemaking?

• A. Cold stabilization
• B. Skin contact (duration, temperature)
• C. Fermentation T/vessels
• D. Carbonation

Answer: (B)

Skin contact in white winemaking is about keeping the pressed juice in contact with grape skins for a controlled period and at controlled temperatures to influence color, texture, and aroma. White grapes are usually pressed off skins quickly to keep the wine pale and light in tannin, but some styles deliberately use skin contact to extract additional phenolics, pigments, and aromatic compounds. The duration and temperature of this contact determine how much color and mouthfeel are extracted: shorter, cooler contact preserves delicate floral and citrus notes with minimal color, while longer or warmer contact can give more body, a tannic structure, and a deeper hue, producing distinctive styles such as orange wines.

Other listed options relate to general or non-specified steps: cold stabilization is a common pre-bottling treatment to prevent tartrate crystals; fermentation in vessels is a standard part of winemaking across styles; carbonation is typically used for sparkling wines, not still white wines. The technique that uniquely highlights how white winemaking can be adjusted to affect the wine’s character is skin contact.
