I've made two batches of this. The first, following this recipe above, took one week to jell. For the 2nd batch I used these ingredients and one package Sure-jell low sugar pectin and followed their directions on the insert for the process. The 2nd batch jelled within a couple hours. Sure-jell has you mix 1/4 cup sugar with a packet of their powdered pectin. You bring that mixture and the wine and berries to a boil and then add the rest of the sugar. Bring to a boil for one full minute then pour into jars and water bath.
