1. Do not drink. Red wine can only be stored for 3 to 7 days after opening the bottle. After this period, the flavor and taste of the red wine will disappear, become bland, and the quality of the wine will also change.

2. Long-term exposure to air has oxidized the wine, and a large number of harmful substances have entered the wine (such as haze, dust, bacteria, etc.). At this time, the wine should have strong acetic acid The taste is accompanied by various sediments. I believe you will feel nauseous even if you bite the bullet and take a sip. For this kind of wine, I'm afraid it won't be enough for cooking or soaking your feet. I strongly recommend that you pour it out directly.

3. Not only cannot you drink wine that has been left open for a year, but you cannot drink wine that has been left open for such a long time, even if the bottle is opened and the cork is put back in.
