/diy/ - Do It Yourself

I'm worried.

I made some hard cider. Threw in some Lavlin E-1118, buncha sugar, seemed to come out fine. So I put it in secondary to sit for a while.

It was absolutely still for a few weeks. No movement on the airlock. But today, I noticed the ticking sound of the lock inner-piece moving around again. I'm afraid to open it up again to see what's going on inside. Why would it start outgassing again after week of stillness?

Am I going to crack this open and find it's a hell of bacterial forest growth caked onto the top of my brew?
