Terroir-driven differentiation of phenolic profiles in grapes and wines: A case study of sub-regions in the eastern foothills of Helan Mountains

Key Points

• Distinct phenolic profiles were linked to terroir variations, enhancing understanding of regional wine characteristics.
• Key findings establish that specific sub-regions of the Helan Mountains significantly contribute to the unique phenolic content of wines.
• The study employs a comparative analysis of grape and wine samples from various sub-regions to assess phenolic differentiation.
• Implications suggest that terroir should be considered for optimizing grape cultivation and wine production in these areas.
