Difficulty: Medium
Correct Answer: Using whole-cluster fermentation (including intact stems)
Explanation:
Introduction / Context:
Color in red wine largely derives from anthocyanins in grape skins. Winemaking choices determine how effectively these pigments and copigmenting tannins are extracted and stabilized. Some practices intensify color; others trend toward lighter, more aromatic styles.
Given Data / Assumptions:
Concept / Approach:
Higher fermentation temperatures, frequent cap management, and extended maceration generally increase extraction of color and tannin. Saignée increases the skin-to-juice ratio in the remaining must, often deepening color. Whole-cluster fermentations tend to yield lighter color and tannin, partly due to intact berry fermentation and stem inclusion, which can raise pH and dilute or alter extraction.
Step-by-Step Solution:
Verification / Alternative check:
Comparative trials show whole-cluster ferments often produce paler hues and different phenolics versus fully destemmed ferments, while saignée frequently intensifies color in the principal lot.
Why Other Options Are Wrong:
Common Pitfalls:
Assuming whole-cluster always increases color due to added tannin; in practice it often lightens color while affecting aroma and texture.
Final Answer:
Using whole-cluster fermentation (including intact stems).
