Everytime I seal my fruit
Everytime I seal my fruit, such as grapes, blue berries, strawberrys, 5 or 6 days later, I notice they have a fermented taste. Why?

That can happen with certain fruits, especially berries and grapes. They continue to release natural gases as they ripen, and vacuum sealing reduces the oxygen around them. In some cases, this can create an environment that causes the fruit’s flavor to change or develop a fermented taste. For best results, we recommend using our glass containers for delicate fruits, adding a paper towel to absorb excess moisture, and freezing berries and grapes if you plan to store them for longer periods. It’s also best to start with fresh, dry fruit that isn’t already overripe. We’re sorry for the inconvenience and appreciate you sharing your experience with us!
