Get some grape juice.
Mix the grape juice with 2 parts water. (The less water, the stronger the wine. Use all grape juice if you want it really strong)
Mix in just enough sugar to where it starts to turn cloudy.
Add half of a packet of yeast. (A whole packet if you are making a lot.)
Find a container to make the wine in. I would suggest a plastic container.
Poke a small hole in the lid of the container. This is to let the carbon dioxide produced during fermentation out of the container. If the hole is too small to let the carbon dioxide out, the wine will spoil, but if the hole is too big, and air gets in, you will have vinegar. Experiment, this part takes some experience.
Mix everything together and put on the lid.
Store in a cool, dark place for 3-7 days. (Until the small bubbles stop rising to the top.)
Warning: Step 8 smells. Bad.
After the bubbles stop rising, open the bottle and prepare a white coffee filter.
Run the mixture through the white coffee filter to get all of the excess sugar and yeast out.
Throw away the filter and all the stuff in there.
Enjoy!
