as to the statement that all fresh grape juice kept in a container for more than 30 days will ferment, I have grape juice in my refrigerator that I squeezed myself in July of 2007 and it has not fermented in the least.

Every time I put it in the freezer, it freezes solid. Alcohol will not freeze in conventional home freezers.

What I have proves that preservation of wine in its non fermented state is possible... just as it was possible 2000 years ago.

History records non fermented wines that kept for years.
