Ok. I brewed my first batch of beer. After a few days (4 now to be exact) nothing happened with my yeast for whatever reason. I checked the gravity to confirm. I actually have two questions:
1. Is it ok to repitch the yeast?
2. I tasted the beer when I checked the gravity and it tasted terrible. I want to say almost metallic. Kind of similar to Natty Light which is obviously what i dont want. Is that a bad sign? Should I just give up on this batch and try again?
Thanks for the help.
