Q&A for How to Make Grape Juice

Yes, you can freeze grape juice.

Sugar is optional. If the juice is lacking sweetness, add sugar to taste.

I put all my grapes in a big pot, mash them with a potato masher, and then add just enough water to cover them. You should not need more than 1-2 cups of water.

No, however it will last longer canned. It should last a week or two if you store it in the fridge.

Grapes seeds are usually very small and can't harm you. If you really do want to remove all the seeds, though, you can take a thin piece of cloth that water could easily flow through and place it over a bowl. pour the grape juice slowly over the cloth and the seeds should rest on top of the cloth while the juice flows through to the bowl.

You can, but you will regret it as the acid from the grapes will start to burn or irritate your feet.
