This utility model discloses a tilting wine pourer for convenient storage, including two sets of bottle necks connected by a connecting strap. The lower inner surface of each bottle neck features a quick-release sealing connection structure for improved ease of installation and fixation. This tilting wine pourer, with its quick-release sealing connection structure and dual structure of rubber sealing rings and threaded connections, allows for rapid assembly and disassembly of the pourer from the bottle while ensuring a tight seal at the connection point, reducing contact between the wine and air and facilitating long-term storage of any remaining wine. The dual-branch design with air vents not only allows for simultaneous pouring of two bottles of wine for easy mixing but also balances the internal and external air pressure of the bottle, preventing splashing or interruption of pouring due to pressure imbalance. It also regulates the flow rate, allowing for optimal mixing of two different liquids at different flow rates, making the pouring process smoother and more convenient.
