Due to the fact that the trace elements in the wine still undergo reactions and changes after being filled out of the factory, the content of irritating substances continues to decrease, aromatic substances continue to be generated, and the longer shelf life of sauce wine increases the probability of these reactions occurring. Therefore, when filling, porcelain bottles will be used, with a tight mouth and good insulation performance, which can effectively prevent the entry of oxygen in the air, thereby effectively preventing the decomposition of alcohol extracts and the oxidation and deterioration of the wine, thereby maintaining the original flavor and extending the shelf life of the wine.
