If your gummies are sweating, there is a possibility that they have been contaminated or have been in storage too long. You can easily check for contamination by placing a single gummy onto a white piece of paper and checking it. If you see any discoloration on the gummi, then it has been contaminated and should be disposed of immediately. You can also use this method to test if the flavor is still good without having to eat one! Simply run under hot water for 30 seconds before eating them. They will not look fresh anymore but they will still taste great!
