Tested your beer and it doesn't taste quiet right...
Chances are you have a germ, maybe something wasn't clean. Wine can handle handling better, beer is very sensitive to germs, air, everything b/c it's only 5%.
So what do you do? You can improve the taste slightly by filtering and carbonating, but you may just have to throw it out.
How avoid this in the future? Cleanliness is godliness in everything, especially beer making, it will not handle any miss handling.
