Transfer to a large stockpot. Continue to mash and transfer until all the grapes are done. Slowly heat the mashed grapes and juice over low heat until they come to a low simmer. Cook for 10 minutes. Strain the juice though a cheesecloth lined colander placed over a large bowl or saucepan overnight. Pour the juice into jars, cover and refrigerate.
