Someone on Freecycle posted that they had grape vines that needed to be picked.
The kids came along and Lillian helped me pick some. I did not want to take them all.
In sterilized jar place 1-2 cups grapes.
Add 1/2 cup sugar.
Fill to top with boiling water.
Seal jars at once with 2 piece lids. Process in water-bath canner for 10 minutes. Remove from canner and keep out of drafts(cover with a towel). Next day remove metal lid-bands, and label with date and contents.
Let juice stand 3 to 4 weeks before using.
Strain juice from grapes and use juice.
