Grapes in our Japanese friends

Our Japanese friends (Yoshio & Anders) told us that we can just come to their house and get/pick more grapes, because they can’t eat it all and they don’t know what to do with them. They told us that we can make some wine.   Is that possible?  We don’t know how to make a wine and it will take some time to do it. CL said that maybe we can make a grape pie  . Will it be good? I haven’t heard a grape pie before.  It maybe good to make a saft (juice) but the question is HOOOOOOOOOW can I do that? What should ingredients I need? It is really sounds great and interesting to experiment things that we haven’t heard or tried it before. I just really hope that we can decide sooon what should we do those grapes.
