Im brewing american wheat ale from a kit I bought from MoreBeer, I started my yeast a day in advance, which i figgured out pretty quickly wasnt necessary. Fermintation ,after pitching my yeast, started within a few hours, by the next morning, it had about 3 inches of foam on it an was working furiously. I couldnt get my temp below around 78F here in central texas. I broke my hydrometer so i cant test specific gravty. After only 4 days the foam disappeared,and I cant see any activity. I was wondering if it would be wise to add some finishing sugar to it and start fermentation again, and therefor increade the alcohol content, any feedback on this would be greatly appreciated. Thanks in advance.
