Three and six percent wine? That isn't wine; that's grape juice. Most wines run about 12%. Three percent is even weak for a beer.

Answer 3

In wine, the alcohol percentage is the percentage of alcohol by volume, as opposed to percentage by weight.  Most table wines range from 9% to 15%.

The wine maker tests this during to fermentation process.  He stops the process when he has the desired amount of sugar and alcohol.  Continuing to ferment will create a higher alcohol percentage and leave less residual sugar.
