In the Bible, they reference the term ‘New Wine’.
‘New Wine’ is wine that has not finished it fermentation process and so still has a high sugar content and is still ‘sweet’ while having an alcohol content about the same as to day’s beer, 4-7%.
Fully fermented wine will have a 12-15% alcohol content and ‘Fortified Wines’ have near 20%.....................
