Storing Greek yogurt properly ensures it remains fresh and maintains its texture and flavor. To achieve this, you should refrigerate your Greek yogurt immediately after purchase, keeping it at 40°F or lower. This temperature inhibits the growth of harmful bacteria that can cause spoilage. Unopened Greek yogurt typically has a shelf-life that extends a few weeks past its sell-by date, which gives you a good window to consume it at its best quality.

Once you’ve opened the container, it’s essential to reseal it tightly to prevent any air, contaminants, or odors from affecting the yogurt. Each time you serve yourself some Greek yogurt, use a clean spoon to avoid introducing bacteria into the yogurt, and to help keep it fresh, it’s recommended to use a separate bowl rather than eating directly from its original container. If you’re looking to keep the Greek yogurt for an extended period, freezing it is an option and can extend its shelf life for up to 2 months, although this may alter the texture, making it best suited for cooked or baked applications upon thawing.
