I made my first batch of wine last fall with the help of a friend whose family has done it for many years. Well it turned out great. Even my friend thought it was something quite special, all in the grapes I guess. Anyway the wine is quite bubbly, the corks even make a slight pop when you pull them out. My friend wasn't sure why this happened. He said his aren't this way and we used all his ingredients. Anyone know why this would happen? I'm pretty sure the fermentation had stopped before bottling as it was in a carboy for 4 months.
