There is no easy version. The reason why grapes will ferment by itself is because wild yeasts has contaminated it. You will most like poison yourself if you drink those stuff.
For fresh grapes, remove the stems and get a large straining bag and strain the fruit juice. You should inspect the grapes yourself and discard any grapes that looks rotten. After getting the juice, you should follow the standard home wine making procedures and use proper equipment and ingredients to ferment the juice.
Easy version:Crush grapes, put them in sealed container of sorts, let them ferment. It probably won't taste that great, but it works, even with store-bought grapes!
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
