As a complete novice I have been making a simple brew: one third of a
litre of fresh pressed supermarket red grape juice and granulated sugar
and baking yeast made up to a final volume of one litre at about 9% ABV.
When i buy a bottle of supermarket red wine after a couple of days of
being opened it soons turns sour. But my home made concoction does not
seem to do this and just remains the same and is drinkable.
Anyone with an explanation why this home made behaves differently ?
