Can you drink mulled wine the next day?

Generally, whether cooked red wine can be consumed the next day depends on the storage method and its condition. If it has been properly sealed and refrigerated without signs of spoilage, it may still be safe to drink; however, if left at room temperature or showing signs of spoilage, it should not be consumed. Detailed analysis is as follows:

If the cooked red wine is promptly transferred into a sealed container after cooling and stored in a refrigerator at 0–4°C, and if there is no unusual odor, cloudiness, sediment, or discoloration the next day, it is generally safe for consumption. Refrigeration helps inhibit bacterial growth and slows down ingredient degradation. Before drinking, reheat the wine thoroughly until boiling to eliminate any potential microbial contamination.

If the cooked red wine was not sealed properly and left at room temperature for more than four hours, or if it develops sour or rancid odors, appears cloudy, or shows flocculent particles or sediment the next day, it should not be consumed. Cooked red wine often contains fruit and sugar, making it prone to bacterial growth and oxidation at room temperature, which could lead to gastrointestinal discomfort if ingested.

When preparing cooked red wine at home, it's advisable to make only the amount needed. Any leftovers must be immediately sealed and refrigerated, and should not be kept for more than 24 hours. Use fresh ingredients during preparation and avoid adding excessive sugar. Always inspect the wine carefully before consuming, and discard it immediately if any sign of spoilage is detected.
