Sparging is a common technique in wineries that consists of injecting a gas, normally before bottling, in order to displace the dissolved oxygen in the wine and prevent oxidation. The objective of this study was to examine the effect of sparging on wines with three different levels of dissolved oxygen and the evolution of the chemical parameters in a bottle. This study was carried out on two white wines, and . The results indicated that sparging did not immediately affect the chemical parameters in the white wines, but it did affect their evolution in bottles, with a greater effect found in the wines than in the wines. Sparging, which was carried out to remove oxygen from the wines, had a protective effect on their color during the time in the bottles, preventing a more rapid decrease in free SO. The effect of sparging on the volatile compounds of the wines was more evident in the wines, which showed a reduction in their content, possibly due to carry-over when the N was applied. With regard to the effect of sparging on the sensory profile of the wines, no immediate effect was found. However, the wines with a DO content of 6 and 8.4 mg/L to which sparging was applied evolved better in the bottles than the deoxygenation wines, showing more fruity notes and fewer oxidized and phenolic aromas (mainly in the wines).
鼓泡是葡萄酒厂常用的一种技术，通常在装瓶前注入一种气体，以置换葡萄酒中溶解的氧气并防止氧化。本研究的目的是考察鼓泡对三种不同溶解氧水平葡萄酒的影响以及瓶中化学参数的变化。本研究以两种白葡萄酒进行。结果表明，鼓泡不会立即影响白葡萄酒的化学参数，但会影响其在瓶中的变化，其中[某种葡萄酒名称1]葡萄酒受到的影响比[某种葡萄酒名称2]葡萄酒更大。为去除葡萄酒中的氧气而进行的鼓泡，在葡萄酒装瓶期间对其颜色有保护作用，可防止游离二氧化硫更快地减少。鼓泡对葡萄酒挥发性化合物的影响在[某种葡萄酒名称1]葡萄酒中更为明显，其含量有所降低，这可能是由于施加氮气时的携带作用。关于鼓泡对葡萄酒感官特征的影响，未发现立即产生的效果。然而，施加鼓泡的溶解氧含量为6毫克/升和8.4毫克/升的葡萄酒在瓶中的变化比脱氧葡萄酒更好表现出更多果香，氧化和酚类香气更少（主要在[某种葡萄酒名称1]葡萄酒中）。
