I just made a partial mash beer as an exercise, since it's been a long time since I brewed last.
Well, I think I'm rusty.
I must have pitched some old, non-viable yeast because after 18 hours, I'm smelling vegetable odors with no activity other than the slightest beginning of kreusen. My solution? I threw in some dry yeast I had sitting around and tossed in some hops in hopes of covering up any off odors.
Am I wasting my time and is my beer ruined? God, it's been years since I've asked that question, but I'm pretty ticked I made such a stupid mistake.
