To make the juice:
In clean, sterile hot jars, place
1 Cup cleaned, de-stemmed grapes
1/2 – 1 Cup sugar
Hot-boiling water to within 1/2 inch of top
Put on lids and rings, and process for 10 minutes.
To use, strain, into a pitcher. It’s been a while since I made this, but I recall diluting it to taste.
Not to hard to find grapes, if you ask around. Many farmers/friends have a well-producing vine.
