Yes. This recipe was tested using apple juice but you can so use grape juice, cherry juice, orange juice, cranberry juice, and more to make these gummy candies.  You may also need to increase the amount of gelatin when using other fruit juices. Make a small test batch using your preferred fruit juice and adjust it based on your preference. Do not use pineapple juice to make homemade gummies. Your candy will not set up properly. Gummies made using other fruit juices may be more flavorful, so you won't need to add candy oil. They will also be more colorful, so you can skip adding food coloring.
