I made my first batch of hefeweizen (which was also my first all grain batch). It is very cloudy. There is lots of sediment in the bottom that is grey in color and smells like bread yeast. When I drink a few sips, it makes my tongue feel a bit numb and then my mouth starts to produce phlegm. It doesn't taste horrible, but it certainly doesn't taste great either. I have opened 2 bottles and have been unable to get even 1/4 of either of them down as my mouth gets all funky when I drink it. Is it safe to say it is infected?
