How long can you keep glue wein?

Gluehwein, or mulled wine, can typically be stored in the refrigerator for up to 3-5 days after it's been made. To maintain its flavor, it's best to keep it in an airtight container. If you want to extend its shelf life, you can freeze it for up to 3 months. Just remember to thaw it slowly in the refrigerator before reheating.
