The preservation and storage of sweet wine has always been a technical problem. The fermented sweet wine can be stored at room temperature for 1 month. Moreover, it can not be completely sealed during storage, and secondary fermentation after sealing will cause flatulence and damage the packaging.
But some time ago, Beijing De Machoke New Technology Development Co., Ltd. will adopt a new patented technology-"infrared computer-controlled sterilization technology" to sterilize and package sweet wine. The application of new technology will break through the technical barriers of traditional storage and preservation, and it is expected that the shelf life of Changle Yukun sweet wine will be extended from 1 month to 6 months. I hope this technology can be used as soon as possible to extend the shelf life of sweet wine.
