I just smacked my pack and it broke the seal in the corner. I was planing to brew tomarrow. Can I just put it into a bottle with some tin foil over the top?
I'd make a starter as fast as you can and get an airlock on it. You can use foil over the top of a container instead of an airlock, preferably with a small opening, as long as you sanitize it first and fit it loosely over the top. Too tight and it will pop.
I wouldn't risk something getting into my yeast by leaving it open in the fridge OR getting it knocked over and spilled.
