So my dad did up an extract kit scotch ale. This is about his 4th or 5th batch, but his first bad batch.
He brewed it up like normal, cooled it, pitched in the yeast, put it in his cellar...and nothing. No bubbles in the air lock. He called me and I told him he probably threw in the yeast too early or it was bad yeast. It had only been 4 days so he got more yeast and threw it in. Still nothing.
So what could have happened?
Two bad batches of yeast? Doubt it. Too cold? Doubt it. Its the same room that produced the exact same scotch ale the first time.
I didn't actually see the set up, so I don't know if his specific gravity was falling or if there was any krausening. And he's thrown it out and since brewed up another batch that is doing fine in the same carboy in the same room.
So what could it be? Didn't get the stopper in so the gas wasn't passing through the air lock? Over zealous on the cleaning and left enough in the carboy to kill the yeast? I'm at a loss.
