1. First check the status of the plug. If it is stuck at the neck of the bottle, you can first remove the envelope with a knife to facilitate viewing and the next step. 2. Use a paper towel or towel to clean up the debris from the bottle mouth. At this time, it is best not to continue to use the corkscrew to drill into the wine cork, otherwise it is easy to press the remaining half of the wine cork into the wine bottle and contaminate the wine. 3. With the bottle tilted, use the corkscrew to slowly drill into the broken cork toward the bottle wall. If the cork is very short, you can drill straight through the cork. Finally, slowly lift the cork vertically. This avoids pushing the cork into the bottle. 4. If the broken cork has cracked and fell into the bottle with a little force, the wine has to be poured into the decanter immediately. When pouring wine, it is best to use a coffee filter or similar filter screen to quickly transfer the wine while filtering out the cork sawdust. If you move fast enough, the wood chips shouldn't affect the wine too much.
