I would like to learn how I can make fresh grape juice in autumn and have it in winter. I don't want it to turn into wine, because I will have my kids drink it. And, I want to prepare big amounts, say 15-20 litres, so that they can have a glass every day during winter.
So, what is the way of keeping big amounts of fresh grape juice still fresh months later?
Also, I don't have big space in the flat, nor do I have a cellar etc... I have glass jars with plastic covers which can contain upto 8 litres.
Thanks in advance.
