How long can homemade kefir be kept?

Just like yogurt, homemade kefir can be kept for 2 to 3 weeks in the refrigerator in an airtight container. 🥄🥰 However, to extend its shelf life, avoid eating it directly from the jar. But, since it tastes so good and is so versatile, you'll likely finish it in a few days! 💚
