Disparaging? Moi?
The basic difference between wine grapes and table grapes is the acid/sugar balance, Tony. Although your taste buds will tell you otherwise, wine grapes contain more sugar than table grapes, but a higher proportion of acid (tartaric, malic and a little bit of citric). It's those acids - the total amount and the relative proportions - which actually produce the resultant wine characteristics. Table grapes have less acid (the reason why they taste sweeter) and so wines you make with them do not develop in quite the same way.
That is NOT to say that you can't make decent wine from table grapes - you CAN, but you'll probably need to play about with those acid proportions. However, the first thing to do is to find out what your grapes will do by themselves - make up a gallon (or whatever amount of juice you can extract) and suck it and see. You can always blend it with something else later if you really don't like the results.
I'm going to guess that you could produce something of about 8 to 9% ABV from your table grapes. Adding a half-pound of sugar would be all you need to achieve 10.5 to 11.5 % ABV. First, though, get a specific gravity reading of the unfermented juice and one for the fully fermented juice with no additions and then you can calculate your natural sugar content (unless you have a more direct way of measuring sugar content in your lab

).
So - press the grapes in a bucket as best you can, leaving everything in the mix, and sprinkle on a level teaspoon of the yeast you've chosen (yeast has an input on the wine characteristics too - general purpose wine yeast will do the job, though). Let it all ferment for a couple of days and then strain off the liquid into a container under an airlock. That's it until it stops bubbling and clears. Rack it off and let it age for a couple of months, then put on your wine-critic's head and see what you think. It will probably be ultra-dry and on the flat side tastewise, but keep going and note down absolutely everything which comes to mind when you're tasting it. Those are the things to address for the next time. If you find it a bit lifeless, you can work wonders with a splash of lemonade.
I'll look up the apple and raspberry recipe and post it later.
