Mix gelling agent and sugar well in a large pot. Add wine and bring to the boil while stirring over high heat. Let everything boil for at least 3 minutes while stirring constantly
Fill jelly still hot into prepared twist-off glasses. Immediately close tightly, turn over and allow to cool standing on the lid
Tip: reduced sugar jam
(fruit to sugar 2:1 and 3:1) spoils faster after opening. Therefore it is best to fill only into small glasses, which are consumed faster. Always keep the opened jam in the refrigerator
