The aging process of wine is influenced by various factors, including the presence of oxygen, the temperature, and the storage conditions. While oxygen can have both positive and negative effects on wine quality, temperature fluctuations during storage can impact its chemical composition. This study has investigated the aging of Merlot and Sangiovese wines under traditional cellar conditions and underwater, exploring the influence of storage parameters on their chemical evolution. Analyzing parameters such as temperature, pressure, and chemical composition, the research revealed subtle but significant changes in the wines over time. Both wines showed a gradual reduction in total phenols, anthocyanins, non-flavonoid compounds, and total sulfur dioxide, irrespective of the storage conditions. Preliminary findings suggested that aging wine underwater does not induce significant alterations in its fundamental characteristics compared to traditional cellar aging. These results contribute to a deeper understanding of wine aging processes and highlight the importance of storage conditions in preserving wine quality. Further research is needed to fully elucidate the complexities of underwater aging and its broader implications for wine production.
葡萄酒的陈酿过程受多种因素影响,包括氧气的存在、温度和储存条件。虽然氧气对葡萄酒质量既有积极影响也有消极影响,但储存期间的温度波动会影响其化学成分。本研究调查了梅洛和桑娇维塞葡萄酒在传统酒窖条件下和水下的陈酿情况,探讨了储存参数对其化学演变的影响。通过分析温度、压力和化学成分等参数,研究发现随着时间推移,葡萄酒发生了细微但显著的变化。无论储存条件如何,两种葡萄酒的总酚、花青素、非黄酮类化合物和总二氧化硫含量均逐渐降低。初步研究结果表明,与传统酒窖陈酿相比,水下陈酿葡萄酒的基本特征不会发生显著变化。这些结果有助于更深入地了解葡萄酒的陈酿过程,并突出了储存条件对保持葡萄酒质量的重要性。需要进一步研究以充分阐明水下陈酿的复杂性及其对葡萄酒生产的更广泛影响。
